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.

Hot Shot’s Secret Diesel Extreme is formulated with specific detergents to safely remove and prevent Internal Diesel Injector Deposits (IDIDs), External Diesel Injector Deposits (EDID’s) and other forms of varnish and deposits. Not all diesel additives on the market will remove IDIDs, as a special detergent is needed.

In order to effectively improve your diesel’s fuel economy, horsepower and combustibility, your fuel system needs to be clean of deposits and run fuel with a high cetane rating. Diesel Extreme not only cleans exceptionally well, it also provides a powerful cetane boost of 7 points. This allows for the fuel to burn more efficiently, increasing performance while also reducing diesel particulate filter (DPF) regenerations. The lubricity additive in Diesel Extreme also increases your fuel’s lubricity, improving protection and reducing wear. This helps combat the ill-effects of Ultra-Low Sulfur Diesel.

Diesel Extreme is a fully-formulated 6-in-1 diesel additive that addresses both common and uncommon problems with diesel fuel, making sure your diesel is always running at peak performance.

The Science

The introduction of Ultra-Low Sulfur Diesel (ULSD) coupled with today’s highly engineered fuel systems are creating new problems for diesel owners. Sulfur was a very good lubricant. The removal of sulfur causes all the moving parts in your fuel system to suffer. Waxy soap deposits that were soluble in higher sulfur content fuels are now being formed and are difficult to filter. Fuel systems incorporating High Pressure Common Rail Injectors operate at higher pressures which create high heat. This heat chemically changes the hydrocarbons in the fuel to longer chain hydrocarbons called asphaltenes, which can block fuel filters. The tolerances for the Common Rail injectors are very tight, sometimes around 1-3 microns. This means even small deposits can cause an injector to stick.

Several sources of sodium and calcium contamination occur from residual refinery salts, storage tanks, ship ballasts and biodiesel catalysts, to name a few. Dodecenyl succinic acid (DDS) and hexadecenyl succinic acid (HDS) are commonly found in certain pipeline corrosion inhibitors, refineries and aftermarket additive packages. When the contamination from the sodium or calcium reacts with the DDS or HDS, carboxylic salts are formed. These carboxylic salts have very low solubility in ULSD and are very difficult to filter. They end up depositing on the internals of your fuel injectors causing what are known as Internal Diesel Injector Deposits (IDID’s).

Hot Shot’s Secret Diesel Extreme was formulated to resolve these issues. Diesel Extreme is fully formulated with a powerful injector cleaner, cetane improver, neutral and sulfur free lubricity agent, water dispersant, rust and corrosion inhibitor and fuel stabilizer. Diesel Extreme’s injector cleaner specifically cleans IDID’s as well as the original carbon coking External Diesel Injector Deposits (EDID’s) and waxy soap deposits. Diesel Extreme’s powerful injector cleaner will also clean all components of your fuel system, including upper cylinders, fuel tank, fuel pumps and lines. The injector cleaner is also responsible for bringing asphaltenes and glycerides back into solution and preventing further asphaltenes and glycerides from forming.

With your diesel fuel void of carboxylic salts, waxy deposits, asphaltenes and glycerides in suspension, the problems with filter plugging and injector deposits are solved. DDS and HDS acids are neutralized by the injector cleaner to keep more carboxylic salts from forming. Independent testing has shown that power loss is restored up to 87% in the Peugeot CEC F98-08 DW-10 test with the keep clean level of injector cleaner found in Diesel Extreme. It also passes the ASTM D2068 Filter Blocking Test.

The Cetane levels found in diesel fuel in most states are around 42 to 45. The minimum required by ASTM D 975 is 40. Most diesel engines operate more efficiently with a fuel that has a cetane rating of 48 to 50. Fuels with higher cetane burn more efficiently and more completely than those with lower cetane ratings. Diesel Extreme contains a cetane improver that will raise your cetane number 7 points. There are many advantages to an increase cetane numbers. Cold starting is improved, and less black smoke is seen as a result of the improved combustion efficiency. Less hydrocarbons and particulate matter in your exhaust reduce the blocking of your Diesel Particulate Filter and using Diesel Extreme in your fuel has been shown to have 83% less DPF regenerations, saving you time and money. Increased cetane levels have also shown to improve fuel mileage and power. Fleet tests with Diesel Extreme have shown an improvement in fuel mileage up to 7.3% due to the combination of our injector cleaner and cetane improver. This combination is also responsible for restored throttle response.

Diesel Extreme contains a neutral lubricity additive for fuel pump and injectors that has a proven a wear scar reduction of 60µm in ASTM D6079 test. A Military grade non-alcohol-based water dispersant lowers the freeze point of water in fuel over 32°F over competitors water dispersants. With the condensed water in the fuel removed, the major cause of rust, icing in cold weather and the growth of microorganisms in warm weather is inhibited. Diesel Extreme also contains a package that inhibits rust and corrosion in the tank and lines and has a NACE corrosion test rating of A. To round out the package, a specialty fuel stabilizer was chosen that contains anti-oxidants, metal deactivators and dispersants.

    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.

    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.

      I know this is old message, but to anyone with similar situation. Unless psi dangerously low, or insanely burning oil don’t rebuil. I had 2 detroits and 2 cats running past 1.1 mil with no issues. One had coolant go to the engine at 1.22. Changed the gasket, rebuild the head and changed main shaft bearings and back on the road. Don’t rebuild unless really necessary. Best of luck
