    Holy toledo

    I had a starting problem with the fuel system, low pressure, low idle, and low boost on my 2004 f250 6.0, friends told me about this stuff and for two years I had not bought it. Today I did and I drove it for about an hour after adding 32 ounces to the oil and 12 ounces to the fuel, had about 15 gal in the tank. When I started it I had the same problem with starting and low Idle, took it for another ride and holy toledo I had increased boost and acceleration. When I got back the starting problems went away idles great. You saved me from being raped by a dealership…..Thanks

    First use of Diesel Extreme

    I just put in my first dose of Diesel Extreme in my ’05 F250 6.0 and went a little heavy by mistake (probably .8qt instead of .5qt), will this hurt anything?

    I was impressed the Oil Stiction Eliminator that I had to try the Diesel Extreme. The performance is back. Light throttle on maintaining speeds and very little black smoke on acceleration. Great products, you won’t be disappointed.

    Ran the diesel extreme through my truck and changed the fuel filters at same time WOW. Did it clean out my fuel system. Less than 1000 miles I ran out the last of diesel extreme and pulled my fuel filters they were coal black. I have 305,000 miles on my truck and have never seen my filters that dirty and they are usually only changed every 10,000 miles. So I know that it really cleaned my entire fuel system will definitely be using Diesel Extreme again.

    Question

    (verified owner)

    I have an 02 lb7 duramax with the amazing injector problem. Just bought the diesel extreme. Will this help eliminate my white smoke issue. Smokes during idle. Smokes while in drive and smokes on take off. Some days smoke more than others. Will this help and how many treatments will I need to do before I get these notorious lb7 injectors restored?

      Hi Lyle, yes the Diesel Extreme is the product to use! Simply use the recommended treatment in 2 or 3 back-to-back fill-ups and it will restore the injectors (or your money-back!)

    (verified owner)

    I like this product. I was have a fuel problem every time I pulled a trailer. The warning light would come on and reduce power on my 2008 Chevy dully. I have a Duromac diesel and I continued to fight the problem of changing the fuel filter. The last time it happened I had about 200 miles on a new filter. After checking with a Diesel mechanic he said I would need new injectors at a price of about $7,000. Then I went on line to see what the injectors would cost and do the job myself, that when I saw your ad for diesel extreme and thought I would try your product prior to changing injectors. I’m seeing a major change in the performance of my truck not to mention an increase in mpg. Your price is a lot cheaper than changing injectors. I mentioned your product to a friend and he stated he has already been using this product and doesn’t have any problems with fuel filters and doesn’t pull any maintenance until after 3000 miles and he also pulls trailers. I just purchased your EDT to add in my fuel.

      Hi Jim, yes the Diesel Extreme 4 times a year will be a great regimen for the EcoDiesel. Just don’t use in the same tank as Lucas, or mix additives in general.

      Also, we think you’ll love our EDT (Everyday Diesel Treatment) fuel additive in between treatments of Diesel Extreme!

  19. Steve

    Question

    Cost aside, any harm in running your Diesel Extreme 16oz per every 30-35 gallon tankful , instead of using your EDT? The reason is I’ve got a new- used 2006 Cummins that has had its injectors and fuel neglected, and I want to drop the proverbial hammer on potential injector problems and eliminate excessive small amounts black smoke coming out of pipe upon acceleration.

    5 out of 5 Quick start and smooth, I am sold on Diesel Extreme

    (verified owner)

    95000 miles on my Cat 3126B when I bought it and the previous owner never added anything, it had been sitting for almost a year when I bought it, it was starting hard, idle RPM was surging from 720 to 770, someone told me to try Diesel Extreme so I did, within a couple hundred miles it was getting better, after 2 tankfuls about 1200 miles it now starts good, runs smooth and idles at 750 plus or minus 5 rpm. I am now about 2000 miles into the Stiction Eliminator and it sounds smother, no smoke. I am very happy with both of these products.

      The first/main differentiator in Diesel Extreme to look for on an SDS sheet is 2-Ethylhexyl:
      Morey’s Diesel Quench: <10%
      - Hot Shot's Secret Diesel Extreme: 49%

      Not necessarily George, BUT, you should fill up the tank whenever it gets down low enough to add 4 or 5 gallons of gasoline to dilute the Diesel Extreme. Also, don’t drive the truck aggressively until the Diesel Extreme is gone.  Diesel Extreme boosts cetane which is just the opposite of what a gas engine needs (octane).  Cetane speeds up the burn and octane slows down the burn.  With Diesel Extreme in the tank you may get hard starting when engine is warm and get spark knock.

      Levi… In regards to your response to George (DE in gasoline)…. you were explaining the difference between Cetane & Octane (flame front retardation)….. would it be correct to understand that the Higher the (pump) Octane rating (ie: 91-vs- 87) the Slower the flame front during the burn period?…… which would be advantageous in higher cr engines with, say… 10:1 or higher cr’s ?

      Mike,

      We would recommend you put in 5 quarts of Diesel Extreme.

      With it being 8-year-old diesel fuel, we cannot be sure 100% if it will make it like new.

      Please let us know if it does work.

      If it does not do what you want, we do offer a money back guarantee.

      Hello Kelly! With Diesel Extreme, there is really no specific year/make/model bias as long as it’s a diesel! The Stiction Eliminator is different as it will clean out the oil side of injectors in ’99-’07 Fords. We do recommend both products (the Diesel Duo) to see the best results, even in 2010 and newer Ford diesels.

      Online, there is a 10% discount when you buy multiples of (6) 2QT or 1 GAL OR (12) 1QT or 16OZ. Or, feel free to call 800-341-6516 to talk to an account executive!

      Diesel Extreme’s benefits are long lasting; using sooner than the recommended 6k miles/6 month intervals won’t provide enough additional benefit that it becomes cost effective to use more frequently than that. Our Everyday Diesel Treatment is formulated to be a more wallet friendly, maintenance level dose if you’re desiring everyday protection.

      If you’re experiencing a fuel system related issue then we typically recommend a few back to back doses until the problem is corrected. Thanks Eric!

    5 out of 5 Diesel Extreme goodness

    I bought a 2000 F-350 with the Powerstroke 7.3L and only had 90K original miles. A buddy told me Hot Shots Secret was the cats meow so I started by running the Diesel Extreme in the tank to make sure the fuel system was clean. Using EDT on regular fill ups and currently running Stiction Eliminator in this oil change. After I run Stiction Eliminator in this oil cycle I will be using the FR3 product in my oil changes. I honestly don’t know how much this has helped my truck because I didn’t have it long before using the Hot Shot Secrets products but I am sure they have helped. Gives me with a warm fuzzy feeling knowing I am doing what I can to keep my diesel a trucking for many more miles down the road.

    I have a 2003 Ford F-550, 6.0 liter engine with 136,000 miles. Acceleration has been a bit sluggish so I thought I’d try Hot Shots products before changing out injectors. I know according to Fords plug in computer I had a few that were recommended changed. I put about half the 32oz in the fuel tank with about 30/35 gallons of fuel. After driving about 50 miles pulling my 48 foot living quarter car hauler, I noticed better throttle response! Can’t wait to put their oil additive in during the next oil change.

      Congratulations on your new truck! You’ve come to the right place! I would recommend our Everyday Diesel Treatment to keep the fuel system in original condition. EDT addresses fuel quality issues like moisture, low cetane, and prevents corrosion. We’ve also seen great benefits on newer trucks that had regens and DPF issues be completely fixed by EDT, so the smooth burn from the high quality fuel is definitely appreciated by the emissions system. When Lavon from Firepunk Diesel tested EDT in a 2016 Ram, the truck saw a dyno-proven 11 horsepower increase from a few ounces of our EDT, so even new trucks can appreciate the higher quality fuel. You’ll get peace of mind and fuel system longevity all for just a few cents per gallon. 1-2 ounces will treat most truck’s fuel tanks. After you get a few thousand miles on the truck, I’d start working a dose of Diesel Extreme in once or twice a year.

      Our FR3 would by my recommendation for the oil side. FR3 has been proven to reduce wear over untreated Shell Rotella by 43%, which equates to longer engine life. FR3 will help keep the engine from “getting tired” as you put the miles on her.

      Our products will not affect your warranty and we have money back guarantees on every Hot Shot’s Secret product, let us know if you have any more questions, thanks!

    I’ve treated my fuel only once with Diesel Extreme and I noticed my highway MPG is 25+. I just bought a 2007 Dodge 2500 4×4 Cummins with 128,000 miles. If this is going to be typical highway mileage for this truck I’m extremely happy. Purchased the EDT a week ago. Can’t wait to see what kind of results I will get with it.

    Injector eating LB7's Best friend

    On My 3rd. set of injectors, (250k Miles), live in California so get the crap diesel. Started to smell raw diesel and see the light puffs of black smoke out the exhaust at idle (again), didn’t wait this time, stopped at a Pilot truck stop added about 1-2 cups to an already full tank. Drove about 30 miles home, got out No smoke, No smell, trucks idle was noticeably much smoother WOW!! I am sold.
    Been using Opti-Lube no were near the same results. I ordered the 16 oz. Everyday treatment from Amazon. Will be using on the GMC and the 2014 3500 Ram…
    In all honesty I don’t know what would happen if I waited a few more hundred miles or so until the white smoke started, would I have got the same results? (HA! Don’t care, don’t have too) 🙂
    Very pleased.

      Congratulations on the new truck Larry! I’d recommend our Everyday Diesel Treatment, this will ensure that every ounce of diesel fuel you put in your truck is the best it can be. Firepunk Diesel in Plain City, OH tested our Everyday Diesel Treatment in a 2016 6.7L Cummins and proved an 11.2 horsepower increase using their dynamometer. This is due in part to the fuel being optimized for the combustion process, thanks to the cetane boost of EDT. We’ve also seen newer trucks correct DPF and regen issues with EDT, so we know the emissions equipment will also appreciate the cleaner burn of the fuel.

      On the oil side, FR3 Friction Reducer is a great choice. In third party tests, FR3 has reduced wear an extra 43% over untreated Rotella engine oil; this translates to your new investment being on the road longer. Enjoy the truck! Thanks!

      Admin (verified owner)

      Hi David! While Diesel Extreme is a more powerful clean formulated for use every 6 months, the Everyday Diesel Treatment is better suited for everyday use. To better explain; the Diesel Extreme is like going to the dentist twice a year to ensure there is no build up, and EDT is like brushing your teeth everyday to keep your system clean. Going to the dentist everyday would be more expensive than brushing your teeth too. I’d recommend trying our Everyday Diesel Treatment after an initial Diesel Extreme dose. 1-2 ounces of EDT will treat 25 gallons of fuel, saving you money in the long run. Undertreating with a few ounces of Diesel Extreme for a few tanks might help use up whatever is left in your bottle, but in the long run I would definitely recommend our Everyday Diesel Treatment.

      You can use Diesel Extreme with other products, but Diesel Extreme contains the maximum cleaner and cetane improvers, you won’t see compounded benefits when using other products with the Diesel Extreme. You’ll see a higher cost effectiveness when using the products separately. Thanks!

    Diesel Extreme , great product!!!!

    (verified owner)

    i was a little skeptical, but after the first treatment, I immediately notice a difference. On my first trip to town, after adding the diesel extreme, I noticed an increase in the mpgs, at least 3 or 4 more miles per gallon on the interstate. Then on a hill that my truck usually down shift, held in 8 th gear without down shifting. I am very pleased with the product and plan to continue to use it along with the EDT treatment. Finally , a product that does with it says it will do, well done Hot Secret.

    After buying my King Ranch with 180k miles on it. A friend told me about this product and how much it helped his truck so I figure’d give it a try because I didn’t know about how this truck was taken care of. Could tell my idle wasn’t as rough after a few hundred miles plus got a little more spunky and maybe got a mile better per gallon. Now truck is deleted and fixin to do my second dose as recommended.

      Peter, while we have not tested against their product, our product has been the most potent and strongest in system cleaning and fuel boosting properties of all competitors we have tested to date. I do not see an SDS sheet for their product on their website so I cannot answer to the exact strength of their product. We have a money back guarantee, no questions asked policy; they seem to offer a much more complicated service schedule to receive protection with no money back guarantee. They do not have dosage listed on their website, if we base dosage off a customer on Amazon then we offer a more cost effective treatment. 16oz of Diesel Extreme will treat as much as one quart of their product, for a quarter of the price of their product. I would choose Diesel Extreme for quicker results and better results. Down the road if you decide to try both and are not impressed by our superior formula, we’ll honor the money back guarantee. Thank you.

      TSE can be a little more difficult to find locally since we tend to push the fuel and oil additives to retailers before the TSE. If you can’t find any locally on the map feel free to give us a call at 1-800-341-6516 and we’ll help get you some!

      Frank, we offer a money back guarantee, so there is no downside to trying Diesel Extreme out for your issue. As for a length of time, it depends on too many factors to narrow down each case. Most users typically see large improvements between 5-50 miles, and usually report issues being completely resolved before the 100 mile mark. Most users opt to let their truck idle for a little and then take it out for some highway driving. We’re here at 1-800-341-6516 and can offer advice, M-F 8-4:30 EST.

      Frank, your 6.9 is a mechanically gear driven injection pump engine. There are no stiction issues to be concerned with. Stiction occurs with HEUI injectors that require high pressure oil systems that exist on both the 7.3 or 6.0 Powerstroke, especially the 6.0. I used to have a 6.9 however and I have used the Diesel Extreme. Depending how dirty the injector(s) may be could be the difference in how long your performance increase becomes noticeable. If you use the product, I would recommend not drive the truck to the grocery store, but take it on a good non-stop 200+ mile open highway road trip. Stretch her legs! I speak with confidence that you will notice a difference.

    5 out of 5 Diesel Extreme use for 2 years

    (verified owner)

    I Started using Diesel Extreme 2 years ago after watching a YouTube Video of TruckU. I first purchased the product from Amazon. I previously had been using Stanadyne additives in my 1999 Chevrolet K2500 6.5 Diesel Suburban from original purchase new in 1998. The first improvement with Diesel Extreme was sub-freezing startup on the first attempt rather than 3-5 attempts prior to using Diesel Extreme. Over time my highway mileage increased from 17 to 19 miles per gallon using the same Citco Diesel from the same station. After one year of use deceleration rattle dissipated to non audible. The cold morning startup has been the best improvement for me.

    Question

    I recently purchased a houseboat with twin Caterpillar Diesels and a Westerbeke Deisel Generator. The fuel is about eight years old. Just before winterization last year all three engines “bogged” down and stopped running – UGH – Contaminated fuel I suspect. I changed all filters and water separator elements. I have three 250 gallon tanks. Two of the tanks have been empty for about 12 years and have been filled less than 10 times after being cleaned in 2005. The other tank is the one with the old fuel which could have as much as 125 gallons remaining. Several questions: Will your product work in a marine application where the fuel sits for long periods of time? Not knowing the condition of the fuel or the contaminants in the tank, do I need to empty the old fuel before adding Diesel Extreme? Should the empty tanks be cleaned before putting new fuel in or will the Diesel Extreme be sufficient? How much product should I use per tank. Often should I use it. One note, I’ll be taking the vessel on about a 1,000 mile voyage in a couple of months. Let me thank you in advance for your time and interest.

      Mark, our products will work with marine applications, Diesel Extreme would be what I recommend for “waking” up this tank of fuel, and then our Everyday Diesel Treatment is a great fuel stabilizer for when the boat gets put in storage in the future.

      While BP and Chevron both agree that diesel fuel has a storage life of 6-12 months, we find that pretty pessimistic. For your eight year old fuel, one of my only reservations is that the tank was only half full which promotes water build up and corrosion in the tank. If you’re able to look into the fuel with a flashlight we can get a sense of the level of fuel degradation and contamination by seeing how dark the fuel is. Diesel Extreme contains the maximum amount of cetane improver, water dispersant, and is backed by a money back guarantee. If we can’t get that fuel to work, let us know and we’ll issue a refund or send more product, just hang on to your receipt. Worst case scenario is you might plug up a few fuel filters throughout the course of this tank, lowered power from the energy content the fuel has lost, more black smoke from exhaust, etc. The key is fresh, high quality filters to prevent damaging lines and injectors. If the engine or generator starts and runs on the fuel I would top off with fresh diesel fuel. It’ll probably be difficult to start with the fuel, and a headache to keep running on it; if you have the means to safely dispose of the old fuel that would be the headache free way to go.

      The empty tanks should be good to go with either Diesel Extreme or Everyday Diesel Treatment, if you’re able to visually inspect for corrosion/rust I definitely would recommend doing so.

      Two quarts of Diesel Extreme will treat 150 gallons of fuel.

      1-2 ounces of Everyday Diesel Treatment will treat 25 gallons of new fuel depending on your desired dose; a 16oz bottle treats 400. I’d put one ounce per 25 gallons if you’re running the fuel soon, two ounces per 25 gallons if you’re storing the fuel.

      Thank you for your response Spencer! An update following this seasons first visit to the boat this past weekend: Last fall, in a quandary about how to retrieve and then dispose of the remaining old fuel (about 125 gallons), I remembered being told the furnace also operates on diesel and draws from the same tank as the engines. In hopes of “burning up” the remaining fuel, I left the furnace running for the winter – HURRAY – SUCCESS – the fuel gauge now indicates an empty tank. Question: If there are a few gallons remaining, as I doubt the tank is “bone dry”, do I need to be concerned or will fresh fuel and the Diesel Extreme be sufficient to mitigate any negative effects the small amount of remaining fuel may still have? Is it recommended to run the Diesel Extreme with every tank until seasonal lay-up when I switch to the Everyday Diesel Treatment? Also, one important piece of information I didn’t share in my first post, each of the three 250 gallon tanks are aluminum. Again, thank you!

      Nice! Glad we got rid of that fuel easily! Fresh fuel and a dose of the Diesel Extreme will be more than sufficient for diluting the rest of the old fuel.

      You’ll see the results and protection you’re desiring by using Diesel Extreme in this initial tank, then follow up doses of 1 ounce per 25 gallons Everyday Diesel Treatment throughout the summer and a 2oz per 25 gallon dose when storing; 16 ounces of EDT will treat 400 gallons of fuel. EDT also has fuel stabilizing properties which make it perfect if you’re storing the fuel for long stretches of time. A dose of Diesel Extreme every spring offers long term benefits to cover you 6 months at a time. EDT focuses on fuel quality while Diesel Extreme is a potent cleaner and fuel booster.

      No issues with using our products with aluminum tanks; I like the corrosion resistance of aluminum tanks but once corrosion starts it is hard to stop. Congrats on the purchase and we wish you safe travels!

      Kurt, with a 7.3L I’d recommend Stiction Eliminator since it was developed specifically for International and Ford for their 6.0L and 7.3L. Our Diesel Extreme is the crowd favorite and since you only need a dose once every 6 months it’s a pretty easy way to make sure your truck is clean, protected and running strong. A Diesel Duo bundle would be perfect! The money back guarantee is simple; try any Hot Shot’s Secret product in your vehicle, if you’re not 100% satisfied let us know and we mail you a check. If you don’t notice a smoother idle, more power, improved fuel economy, or any other benefit listed on the label or our site we’ll honor the guarantee. Just hang on to your receipt or confirmation email so we don’t have to guess the amount! Limit is two bottles to keep people from abusing our policy, so the Diesel Duo definitely qualifies. Thanks!

      Hello,
      For accidental use of Stiction Eliminator in the fuel tank, we recommend topping off with diesel fuel everytime your tank reaches the 3/4 or 1/2 mark to help dilute it.
      There are no ill effects from accidentally adding the Stiction Eliminator, but it is obviously not recommended. Keep it topped off and your truck won’t even notice!

      I have a 03 Dodge I bought new. I used buy fuel in it it stopped running. Tried for over a hour. Then ups brought my diesel Ex I took the fuel filter off filed it full of diesel Ex and poured some in tank. Turned it over let it set about 20 minutes and then started it. It started right up first or second crank eavey. I have a bob cat it quit. Ran diesel ex in it and cleaned the fuel and after a half hour it started loosing power cleaned the fuel filter witch was full of water. It done it two more times on one tank with diesel ex. It some how took all the water out of tank and lines. I bought it new and we eaven filter our fuel in a funnel besides the fuel filter on our 100 gal tank in back of truck. I use it and have gave some to my customers to help them. It would have cost me over 8900 to have dodge put new injectors in it. I’m not a genius but 29 dollars is a lot cheaper then 8900. Not to mention a lot more power and it runs better than when I bought it new.

    Husband drives 2006 Dodge diesel 2500. Of late, I thought it was running rougher than normal, but hubby didn’t notice, always in that truck. Finally, it flipped a code about injectors, and he limped the truck home. Never had used additives for cleaning in the 10 years we owned it. Our bad.
    Well, I hit the Internet, and stumbled upon Hot Shot Secrets Diesel Extreme. Bought it, added it to fuel, and let it run in the driveway for an hour. Hubby thinks it runs better than ever. Now also using HSS Stiction Eliminator also. Our 10 year old truck runs as smooth as ever. These products easily saved us an unnecessary $2000. repair bill.

    I recently purchased a 2015 Ram EcoDiesel that was a trade-in. It had 98K miles on it. After driving it 400 miles home I got my first engine code: Turbo underboost sitting at idle. GULP????? Bad Turbo? now what?. After going to a local dealer and talking to guys on forums, it kept happening. Of course it would go into limp mode when the code was set so all I could do was reset the code and keep on trucking. Finally, one day I got an injector code along with the turbo underboost, and I wondered “dirty Injectors?”. So i got the Hot Shot Secret Diesel Extreme and put it through my system. I doubled the initial dose-I wanted to hit it hard. Well that did the trick. I have not had one turbo code or injector code Since I used the Diesel Extreme. (P.S. I since have concluded and have evidence that the dealer where I bought the vehicle knew about the codes, and had replaced the ECM among other things to deal with the problem- to no avail). I got a great deal on an EcoDiesel because the dealer was scared of it, and it only needed Hot Shot Secret to make it run like new.! thanks for a great product. I’m sold.

    A.B.E. Towing & Recovery
    Allentown, Pa.

    We are small towing company located in Allentown Pa. Our 2009 Nissan UD 2300DH was starting to have power loss in the pass 9 months. Dealer told us it was a bad EGR and would cost close to 3000.00 to fix with labor. Truck would be tied up at there dealership for a minimum of 1 to 2 weeks. Before I agreed to get this repair done I decided to do some research on chemicals to see if it would help. I looked at many chemicals and nothing really caught my eye that would fix the problem. I did research on your product and reviews, they really didnt give me much to go on. So I decided to go with my gut cause it is normally right.

    We added the products, we started with the extreme boost. After filling the tank and letting idle for 30 minutes, we drove it about 15 miles, already we notice more power better pick up. So we brought it back to the shop and did the oil changed and added the oil additive with the oil change. drove the truck 95 miles and now all of the sudden this truck is shifting better. Before it would shift between gears at 2200 to 2500 rpms, now its shifting at 1100 to 1500 rpm, fuel consumption is not even close to what it was. The jake brake is working better, hill climbing is like is was brand new truck!

    As we drive this truck longer during the night and day it is still improving little by little with BIG results. For $70.00 i may have solved the problem myself which means I saved 2925.00 in repairs.

I suspected bad fuel, took it to a shop and was told it had 3 bad injecters…ouch. After a friend recommended this product,I thought it can’t hurt. After driving it for just 15 to 20 miles it was 90% better! I am convinced! Will run the rest of this tank and see what happens but wow! This could very well save me a huge repair bill.

    I have a 2015 Ram EcoDiesel with 105K miles. I was getting codes for turbocharger under boost, injector problems and throttle control. My ECM was so confused. I added Diesel Extreme to the fuel. All the codes cleared up and I’ve gone 3K miles no problem. All the troubles stemmed from the fuel system. Great results with this product.

    Hello, My name is Myk and I drive an 08 Duramax LMM. My truck has 325k and has been all over the US. Just in the pass few months I have noticed that my fuel mileage and power was dropping and I my truck was going into reduce power mode a lot. Dealership told me I had an bad injector and recommended replacing all of them. Well that make sense do to the mileage but at $495 each that wouldn’t be a cheap bill.
    So after some research one additives to help prolong them. I was told about HotShot products and figured give it a shot. I desired to run 3 tanks with the hotshot back to back to help to give a good clean out. And I do have to say that I’m now on my 3rd tank with out hotshot and my truck still feels like a new truck. I have all the power and fuel mileage that I did when my truck was new.
    I also bought the oil treatment but waiting for my next oil change.
    Thank you for making such a great product. And if you guys have any decals/t-shirts I wouldn’t mind having a few.

    I have a 2006 Freightliner Century Class and I had begun losing power so much so that I had to downshift even though my flatbed my trailer was empty when going up hill. So I figured that if I was going the fuel injectors are clogged or motor was going bad I wasn’t sure because I’m not a mechanic. So I decided to try my luck and buy this stuff. I gotta tell you that I poured two gallons in my fuel tanks and within a hundred miles I noticed an increase in power and now trucks running smooth and the power has increased. Wow I have no doubt that I will need to rebuild in the next hundred thousand miles or so because my truck has 854207 miles on it but in the meantime trucks running great and I want to say thanks to great product and I highly recommend it.

      Hello Lee!
      For Stiction Eliminator, synthetic oil is highly recommended (but not required). Also, most effective when used with a fresh oil change and safe to leave in for the life of the oil.

    Your fuel add sure smoothed out the old John deer 240 skid steer hour meter broke in 2004 lots of mowing, log loading brush cutting, wood spitting, snow plowing dirt and gravel work. . Started to run rough after parking out side all winter with little use, wish I had known about your product then, fresh diesel, and the right amount of hot shot, smoothed my old johnny popper out almost like new. John deer is on the hot shot diet from now on. Thanks for a product that works.

    As everyone here I was skeptical but decided to try the fuel side first. I have been using the white jug fuel additive for several years and hoping it was doing something beneficial for my engine. I have a 2003 long nose 379 C15 Platinum overhauled about 380k miles ago. I put the Hotshot fuel additive in my tanks and within 200 miles my engine was running so smooth I was waiting for a rod to come through the side of the motor. It wasn’t until I stopped for the evening that I could tell just how smooth the motor was running I pulled a nickel out of the ashtray and stood it up on the dash and it never moved. Laying in the sleeper that night it was strange feeling how smooth the truck was running with zero vibration. I can tell you the oil side will get treated next week and I will recommend Hotshot to everyone I come in contact with, I’m sold..

    I just picked up a 2013 gmc denali 2500 a few months ago and this morning decided to put half a bottle of diesel extreme in when i filled her up and all I can say is amazing. The truck is stock with almost 74000 miles on it and its 13 miles from fuel station to my house and averaged 21.5mpg, I know the mileage is going to drop off but the truck instantly felt smoother both at idle and while driving. I can’t wait to see how it feels when I do the oil change and ise your stiction eliminator as well. I push your products to everyone who has a diesel, I’m also pushing my local autozone to get your antigel product in for winter. Thank you for your awesome products, I’ve used them in the past on a 03 F350 I had.

    I tried diesel extreme a few months ago. I was sceptical on these types of things but I won’t it on a contest. So I tried it. I was surprised 2mpg better less need to download shift. I used it in a all factory 2012 Ram 2500 CCLB 4×4 6 speed. Again it is not deleted.

    Have an ’06 Duramax LBZ with 72,000 miles. Been using another brand of diesel fuel additives(no motor oil additives) for a couple years and will switch over to Hot Shots products as soon as my local store gets some in stock, because of the great customer reviews. When I asked the experts here about how to use the diesel additives, I was told NOT to use the Diesel Extreme and EDT at the same time. Great info, fast response, greatly appreciated. Although my Duramax seems to run OK, after I use these products and compare mileage/exh temps/injector balance rates, I will be filing a full review.

    I own a 2003 Dodge Ram 3500 Diesel 4×4. I use my truck only for towing my boats which means that my truck sits a lot in the garage. To give you an idea of how much it sits, I bought the truck new in 9-03 and it now (9-11-12) has 32k miles, not a typo! I have found out the hard way about diesel fuel becoming contaminated with algae and who knows what else. It was to the point where I couldn’t drive the truck for 100 miles without it losing power not being able to go up hills faster than 50mph due to a clogged fuel filter. I saw your episode recently about Hot Shot Secret Diesel Extreme so I decided to spend the cash and buy it. I have so far run 1.5 tanks of diesel with HSSDE added and my truck is almost back to 100%! I think it will be back to perfect after running the rest of my tank through it. I am a true believer of this product and highly recommend it to anyone thinking about buying it. Thank you to Truck U for doing an episode showing what this product can do, I love the show!

    Hey guys, its Max.
    I now have 4,800 miles on my Hot Shot’s Secret and ran the entire bottle of the fuel detergent. Vehicle is running about 50% better. It still misses a little and these are brand new injectors with like 20k miles on them tops. Valves are good they were checked when head job was done, fuel filters changed, new oil cooler, EGR delete, head studs, bypass filter, I’ve done everything to make this truck run right. I think one more run of it in some Rotella t6 would have it running proper.

    My friend told me about this and I used it on my International flatbed which I use to haul cars up and down the east coast. I thought I needed a new truck but he assured me that this could save it and sure enough, I poured it in and 20 minutes later my truck was running better then new. This product is amazing.

    Hey, I’m Tom from the Atlanta, Georgia area. I got a 96 Ford F250 with a 7.3 power stoke diesel. I tried your product for the first time on this past oil change. It made one hell of a difference. The mileage went up. I also tried the Diesel Extreme and I was very impressed with both products. I also have an ’06 F350 with the 6.0, I’m a fixing to try it in that truck also. I was very impressed with the products and in fact I just ordered a case of the Diesel Extreme and I’m fixing to place an order for the Hot Shot’s Secret [Stiction Eliminator]. Thank you very much.

Fuel detergents commonly have five elements: rust and corrosion inhibitor, cetane booster, fuel stabilizer, metal de-activator, and detergent and dispersant. Most fuel detergent products on the retail shelf are a “boost now, die later” product. They contain minimal cleaners and maximum boosters so that the driver experiences only a short-term boost. Trying to “boost” a dirty fuel system is ineffective.

Hot Shot’s Secret Diesel Extreme is designed to support a “clean then boost” strategy. Diesel Extreme is unsurpassed in its cleaning power and will cleanse your whole system including cylinders and lines. It will restore your fuel system components to their original cleanliness and prepare them for maximum response when Diesel Extreme’s cetane booster kicks in.

Diesel Extreme is a concentrated cetane improver which also contains a highly effective fuel stability package. It will tremendously upgrade power and performance in all diesel equipment, increase mileage and provide maintenance economy. Storage stability of fuels will be greatly increased and diesel engines will be kept in a much cleaner and maintenance-free condition. In addition, Diesel Extreme has a stabilizing system to improve storage stability that will prevent polymerization and breakdown of hydrocarbons which results in gum and sludge formation. The dispersant prevents insoluble residues from forming, which are sometimes produced when mixing fuels from different sources. Corrosion is prevented by an inhibitor which produces a protective non-deposit-forming film on metal surfaces in the fuel.

Diesel Extreme will improve cetane in the fuel giving it a smoother, less erratic pressure buildup in the combustion chamber during the ignition delay period, which occurs between injection and ignition. Controlling this pressure buildup eliminates the potential damage to piston rings and rod bearings. Power and fuel economy is increased as fuel burns more evenly and cleanly. Misfiring is controlled. When ignition improves, emissions are reduced and noise levels are lowered. Control of the pressure buildup allows more complete burning of the refractive molecules in the fuel, which steal power and produce deposits and wear. Cetane improvement gives quicker starts and faster warm-up at cold temperatures. Diesel Extreme will lower the minimum starting temperature of a diesel engine approximately 5°F.

Controlling Misfires, Stabilizing the Fuel System, and Improved Engine Performance. The point at which misfiring occurs in a diesel engine is influenced by the temperature of the intake air. Diesel Extreme will lower the temperature at which misfiring occurs by as much as 30°F. The fuel stabilizing system in Diesel Extreme eliminates problems caused by sludge, corrosion, rust or scale in degraded fuels. Sticking fuel injectors and plugged lines and filters are prevented, saving costly fuel and reducing maintenance. Engine performance is improved and wear is reduced when operating with clean, stabilized, sludge-free fuel. Diesel Extreme will not only prevent potential acid and sludge-forming reactions, which cause both corrosive and abrasive wear, but will disperse existing sludge and deposits.
