    I first purchased this product in Phoenix, Az. during the diesel drags last summer. I added the the Extreme Diesel and had a instant increase of MPG up to 21-24 and boost. This is in a 2006 2500 FWD Dodge 5.9 diesel with 122000 miles.

    5 out of 5 try this sh-- it works

    mike

    Got some bad fuel that set my water in fuel light on in my 06 dodge 5.9 cummins. After repeated use of another product and 4 filter changes now i have injector code. Stopped by a friends shop one day and he said try diesel extreme. He grabbed a bottle off the shelf and started pouring it in my tank. I only had 15 gallons of fuel at that time. I ask what do i owe you ? he said nothing you will be back for more. so after about 20 miles truck started running better. so i finished running that fuel down to 1/4 tank. within 2 days the truck is back to 80% and no codes. so back to my friends shop for another bottle. He ask well what do you think? I said i think your right that sh– works. that was 500 miles ago. now back to normal truck has its power back and no injector problems with 166000 miles. Thanks Mark AA muffler & brake

    We were really skeptical when we started carrying this product at our truck stop, as we already had 20 different additives on the shelf. After a slow start in the first few months, these products took off. We now have repete customers buying it. Also, the buyers helps out the curious and skeptical ones to try it and then it becomes their product for life. We highly recommend this product to the fleets. Makes your trucks brand new from the inside again.

    I have ran Diesel Extreme many times before in many different diesels, I have had a lot of comments on how good Stanadyne diesel cleaners were very good, so as I was driving through Canada I found diesel extreme in 2qt size and that will treat 160 gallons and the tanks on the truck are 225 gallons, so I under treated the fuel and I bought enough Stanadyne to treat 240 gallons of fuel, at the end of the day with Diesel Extreme the truck avg. 7.2 miles per gallons 1.3 gallons of DEF, next day added Stanadyne and filled the tank, end of that day 6.5 miles per gallon and 2.5 gallons of DEF The results speak for themselves, will be using diesel extreme again

    5 out of 5 This stuff works

    Michael McNay

    Started with my 07 Dodge dually with the 6.7 Cummins that has 176,000 miles on the motor, we used the recommend amount & have seen our engine running smoother, no unburned diesel fuel smell & increased our mileage roughly 1 mile per gal. while pulling our 20′ enclosed equipment trailer. So I purchase another quart for 1999 C6500 GMC tool & equipment van with a Cat 3126E that was I repeat idling rather rough, it is now running smooth once again. Local store has run out of the product, so I will be ordering 6 qts online to try on our other two tool & equipment vans we use daily. Only question, do you sell a product this good for gas engine?

    5 out of 5 I thought I was screwd

    Tracy D

    My truck would spit out black smoke like a tire fire and had no throttle, like pulling out of the driveway top speed. Happened 5 different times after a stop light of store stop. Tried air filter, D Kleen fuel treatment, fuel filter, MAF sensor. Then a friend recommended Diesel Extreme, I put the recommended dose in and drove it hard for 300 miles up and down the highway no stopping. Only turning around when no on was coming so I didn’t have to stop in fear of it happening again. Ran 3 tanks of this stuff through my truck and it hasn’t happened since. My truck runs like it used too. This stuff saved my ass. I thought I was gonna have to spend $6500 on new injectors. This stuff works as advertised. If you have problems with your diesel give this stuff a try before taking it to the dealer.

    Tired of the engine light coming on only to find that the exhaust filter was the problem. After using your product it has not come on. The VW TDI 2.0 has had it’s share of problems after VW did their fix to comply with DEQ. I’m hoping that the problem is finally fixed and it is looking that way.

    5 out of 5 Fixed my EcoDiesel

    jared.morrow (verified owner)

    I had been plagued by my Ram 1500 EcoDiesel constantly needing to clean its exhaust filter. It would run rough, then the warning lights would come on, and I’d know I had a highway drive on my hand the next day even if I had nowhere to go. I finally gave Diesel Extreme and EDT a try with not much hope that my problems would be fixed. Much to my surprise, the truck started running differently from the first day using them. It runs smoother, quieter, and I have not gotten any exhaust filter warnings for the past two months. I’m so happy Hot Shot has seemingly fixed the issue that has been haunting me for over a year.

      My throttle was sticky for over a year, when I stepped on the excelerator the truck would learch forward. After the first treatment I had a smooth throttle and a smooth engine.. I dont understand how the throttle is affected by this product, but its just GREAT.

    I trust that Diesel Extreme is great. I didn’t notice much difference when I first used it but I will continue using it every 6,000 miles on my deleted/tuned 2011 BMW 335d. The product that I have truly noticed a huge difference from is EDT which reduced my black smoke by about 90%. It reduced how often it smokes and the opacity of the smoke. I will keep using Diesel Extreme and EDT for sure!

I ordered the diesel extreme, I added to fuel per instructions, ran it for 10 minutes at idle and shut it off. 2 days later I figured I would troubleshoot one last time before disassembling and was happy to say the problem was gone when I fired her up. Still running great

    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.

    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.

    Jeffrey (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.

    David Peterson

    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.

    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.

    Increased the drivability and toned down the smoking. I ordered some Stiction Eliminater to complete the process.

    I purchased Stiction Eliminator last year and so pleased I had to see what your other products were like. Used Extreme in the same 2005 Duramax and within the first 1/4 tank I noticed the truck fired up quicker.

    I work with many diesel machines, heavy equipment, and they always give me trouble because of the water in the diesel, after using HotShotsecret they sound like new.

    I recently purchased a 2002 Dodge Ram 2500 with 5.9l cummins I stated with a oil change and add the hot shot stiction eliminator and also add the diesel extreme to the tank. The truck runs so much smoother and going to continue with EDT in the tank at every fill up. So far I love all of the hot shot secret products and will be a long time user.

    5 out of 5 Diesel Extreme use for 2 years

    Salvatore Cosenza (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.

      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.
    Thank you Hot Shot Secrets!

    My name is Shawn, I have a 04 Dodge ram 3500 with 150,000 miles ato the end of a 4,000 mile round trip back home to visit my truck started running terrible. 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.

    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 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!

    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.

Dirt and water in your fuel system steal the power from your diesel. Your engine needs an extreme cleaning. Hot Shot’s Secret Diesel Extreme is a new and powerful formula designed to rejuvenate your diesel’s fuel system’s performance. Add a dose of Diesel Extreme at your next fill up and your engine’s fuel system will be cleaned, restored and boosted to its original performance power.

Diesel Extreme will clean everything in your tank, lines and injector tips and remove moisture. When used in conjunction with Hot Shot’s Secret Stiction Eliminator you will be giving your truck a complete cleaning on the inside. Stiction Eliminator is cleaning the oil side of the engine while Diesel Extreme cleans the fuel side. This product contains anti-oxidants and is not formulated for use in gasoline engines.

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.

Official OSU Test Results »

Reducing the need to perform regeneration cycles: City of Columbus, Ohio »

Directions:
2 quarts treat 160 gallons of diesel fuel.
1 quart treats 80 gallons of diesel fuel.
16 oz. bottle treats 40 gallons of diesel fuel.

Recommended Frequency:
Use one treatment of Diesel Extreme every 6 months.

Uses:

Diesel Extreme is extremely effective in middle distillate fuels to improve combustion and ignition efficiency, enhance fuel economy and maintain fuel in a clean, stabilized condition. Hot Shot’s Secret Diesel Extreme is safe in all diesel engines: semi-trucks, pick-up trucks, farm equipment and autos. Including but not limited to: Ford Powerstroke, Dodge Cummins, GM Duramax, Saab, Volkswagen, and Audi.

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.
