Stanadyne Diesel Fuel Additive Performance Formula meets all fuel system requirements regardless of make, model or year. Approved by OEMs, this formula offers cold weather protection. It reduces the diesel pour point up to 40°F and cold filter plug point by up to 25°F, depending on base fuel. It also offers hot weather protection with lubricants and cetane improver to help when fuel is hot and "thin." This formula increases horsepower, with up to a 5-point cetane gain to improve combustion, resulting in better acceleration, power and torque. This formula reduces fuel consumption. Independent tests show gains up to 9.6% in MPG. This additive makes for easier and faster starting, in all conditions. It reduces smoke and particulate emissions, and is suitable for ultra-low sulfur diesel. This formula cleans and protects with its detergents and deposit modifiers that help protect injection pumps, injectors, nozzles, etc. And it reduces wear with lubricity improvers that restore lubricity to ultra-low sulfur and other low lubricity diesel fuels. It stabilizes fuel with antioxidants that keep fuel fresher. It fights the formation of corrosion and rust. This formula contains no alcoho, so it avoids corrosion and accelerated wear. It helps remove water with special demulsifiers that cause tiny water droplets to come out of suspension/emulsion, so the filter/separator can more effectively remove water. Specially formulated for use with ultra-low sulfur diesel fuel. Can be used with bio diesel fuel up to B20 (20% bio content approved). Increased water separation is shown in bio content up to B20,
