Order the Hot Shot's Secret P040416Z Diesel Extreme Fuel Additive from GAP for your vehicle today. Diesel Extreme is a fully formulated, concentrated cleaner that removes all internal diesel injector deposits (IDIDs) including waxy and polymeric deposits. In addition, Diesel Extreme contains a top tier level of cetane booster, lubricity additive, and fuel stabilizer to provide maximum performance while cleaning the fuel system. Hot Shot's Secret Diesel Extreme is a premium 6-in-1 diesel additive, containing the most concentrated detergent formula on the market. Diesel Extreme fuel additive is formulated to resolve issues related to Ultra-Low Sulfur Diesel and greatly improve your truck's performance and fuel economy.
Engineered with specific detergents, Diesel Extreme will safely remove and prevent Internal Diesel Injector Deposits (IDIDs), External Diesel Injector Deposits (EDIDs) and other forms of varnish and deposits that cause scarring and wear, which leads to premature failure of fuel system components, including fuel pumps and injectors. Diesel Extreme fuel additive also includes a powerful cetane improver, improving your diesel fuel's cetane rating by up to seven points, to improve combustibility, horsepower, and fuel economy. By improving combustibility, this diesel fuel treatment reduces the number of diesel particulate filter (DPF) regeneration cycles that are needed. Diesel Extreme also contains a lubricity enhancer to further reduce wear, a water dispersant, rust and corrosion inhibitors and a fuel stabilizer. Diesel Extreme fuel additive will improve your diesel's fuel economy, increase horsepower, clean injectors, improve cold starts, eliminate excessive black smoke, and improve reliability. This diesel cleaner additive is recommended for use in all diesel engines.
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 up to 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.
1 quart treats 80 gallons of diesel fuel.
16 oz. bottle treats 40 gallons of diesel fuel.
Recommended Frequency:
Use one treatment of Diesel Extreme every 6000 miles.
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.

Super Comfortable shoes.
Size: 11, Color: Charcoal
I purchased these Hey Dudes for my husband. His feet always hurt. The moment he put these on he was so surprised at how comfortable they are. He loves the color and how he can dress them up or dress them down. The material is sturdy and comfortable. He found them great to wear and bring on a recent cruise we took. Comfortable to wear and walk around all day in and wear them at night for dressier nights.
