    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.

    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 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.

    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!

    I own a 2012 VW Passat TDI, can I use this product on my car

    • (verified owner):

      Absolutely, any diesel! Just 8 ounces every 6 months to keep the fuel system clean on a TDI.

    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 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.

    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.

    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..

    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.

    Just finished my first 2 quart bottle and I am sold. This stuff is great.

    i am still have not heard if you can use hot shot in mobil one 1 SYNTHETIC OIL

    • (verified owner):

      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.

    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, 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.

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.
