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.

    I own a 2016 Super Duty 6.7 Powerstroke with 121,000 miles usually average 16.5 to 17mpg. After just 1 tank with the LX4 I could not believe on how smooth it was feeling it felt like it had more power smoother shifting just all around different feeling.I stopped filled up measured 3 Oz. Checked my mileage and was Elated 18.3mpg on the 1st tank . I am worrying about that CP4 fuel pump as anyone who owns a Duramax , Cummings,Powerstroke should be concerned.This product at least gives you a little piece of mind knowing that it’s getting some lubricant and may last like you thought it would when you bought it. Thank You Hot Shots .

    I started using the products in my wife’s Mercedes diesel and then in my RAM truck, the engines seems quieter and the diesel is more responsive and the fuel mileage has increased. Love the product!
