Our Two-Step Fuel Treatment for Protection and Performance

The Signature Series Fuel Pack by Hot Shot’s Secret is designed for diesel engines. This solution will improve fuel economy, lubricity and combustion. The steps include:

  1. Diesel Extreme: Diesel Extreme is a deep cleaner and cetane booster for the initial fuel system cleaning removing internal diesel injector deposits (IDIDs). It’s formulated with a high concentration of cetane, providing up to a 7-point gain. The cetane provides a more complete burning of the fuel, and reduces DPF regen cycles. It also cleans the tank and lines while protecting the fuel system to avoid future damage.

  3. Everyday Diesel Treatment (EDT): Our Everyday Diesel Treatment is a six-in-one fuel booster to increase the quality of diesel fuel. EDT is a concentrated cetane booster to increase power and performance. It also increases the lubricity of the diesel to reduce fuel system wear and failure. EDt also prevents water, rust and deposits from gathering in the fuel system.

Our two-step diesel fuel program will thoroughly clean the fuel system of diesel engines, performance and economy while protecting the system from damage.

For the best results, use 16 ounces of Diesel Extreme in 40 gallons of diesel every 6,000 miles. For tank fills between the use of Diesel Extreme, use EDT. Just 1 ounce treats 25 gallons of diesel, use above 32 degrees F.  In temperatures below 32 degrees F, we recommend adding EDT+ Winter Defense instead. It contains the same 6-in-1 protection as EDT with the addition of an anti-gel.

    Frighteningly Effective

    Brian Alexander (verified owner)

    I was given a bottle of Diesel Extreme with my last order – I’d never used it before and didn’t figure I needed it having used EDT with every fill up since purchasing my 2016 Ram Ecodiesel. Since it was free, I certainly wasn’t going to let it go to waste and tossed it in with my next tank of fuel at about 67K miles… and was in for a surprise. After about 50 miles I became a bit concerned, as I noticed an the engine become uneven at idle as if an injector were starting to fail. Injectors are NOT cheap especially the piezo injectors used in my Ecodiesel, so I was starting to wonder what kind of damage this product could possibly have done and if HotShotSecret would stand behind their product and fix my truck… but from that point on the uneven idle started to smooth out and I saw a 1.3mpg increase in fuel economy just on that 1st tank. I’ve been working on engines since I could push a lawnmower (back when dinosaurs roamed the earth) and my best guess is that the idle issue was not caused by an in injector problem, but rather that some cylinders taking longer to clean up than others. The increase in economy leaves no other explanation than this product does exactly what it is supposed to… and remember I’ve been using EDT since day one, changing fuel filters regularly, and I live in an area not known for poor quality diesel fuel. My compliments to the chef who cooked up this magic witch’s brew!

    I’m glad that I found this product because I did not have to spend thousands on injectors
