Hot Shot’s Secret Introduces Diesel Extreme Fuel Additive


New from Hot Shot’s Secret – their Diesel Extreme Fuel Additive. This additive cleans and boosts diesel fuel systems to return an engine to its original power. See more details below.

Official Release:

Engines lose power and fuel economy over time; Hot Shot’s Secret has the solution. Across the country, diesel owners are turning to Hot Shot’s Secret Diesel Extreme to restore a truck’s original power. With one dose, Diesel Extreme cleans out fuel tanks, lines and injectors, removes moisture, boosts cetane, lubricates the fuel pump and injectors, neutralizes acid and restores fuel economy and power back to the vehicle’s original performance.

Diesel Extreme contains 4X more cetane booster than leading competitors, as well as a top tier lubricity additive and fuel stabilizer to provide maximum performance while cleaning the fuel system. Diesel Extreme is also a fully formulated concentrated cleaner that removes all types of Internal Diesel Injector Deposits (IDIDs), including waxy and polymeric deposits. The removal of IDIDs restores the injector’s fuel spray pattern to help optimize the combustion process; resulting in a complete fuel burn and increased efficiency.

Diesel Extreme’s deep clean provides six months of protection and benefits to keep engines running strong. To maintain system cleanliness and performance between Diesel Extreme treatments, use Hot Shot’s Secrets Everyday Diesel Treatment (EDT) additive with each fill to the fuel tank. EDT is a highly concentrated cetane improver that greatly improves power and performance in all diesel equipment, increases fuel economy and lowers maintenance costs.

Diesel Extreme is extremely effective in diesel fuels for improving combustion and ignition efficiency, enhancing fuel economy and maintaining fuel in a clean, stabilized condition. Trusted in the performance industry both on the road and the drag strip, Diesel Extreme is the official fuel additive of the NHRDA, and is safe in all diesel engines: semi-trucks, pick-up trucks, automobiles, farm equipment and marine applications. These engines include, but are not limited to, Ford Power Stroke, Cummins, GM Duramax, Saab, Caterpillar, International, Detroit, Volkswagen and Audi.
