Product Details
Performance Formula® All Season
The premium all-season, multi-function diesel fuel additive, designed to tackle virtually any diesel fuel related problem.
- Restores/Increase Horsepower – detergents clean deposits in the injection system resulting in improved combustion, better acceleration, power, and torque
- Reduces Fuel Consumption – independent tests show an average of 4% improvement in MPG and gains up to 9.6%
- Cetane Improver – improves combustion resulting in better engine starting, smooth running, and reduced engine noise
- Meets all engine fuel system requirements and will not harm exhaust after treatment systems
- Reduces Emissions – reduces Smoke and Particulates
- Cleans and Protects – detergents and deposit modifiers help protect injection pumps, injectors, nozzles, etc.
- Reduces Wear – lubricity improvers restore lubricity to ultra low sulfur and other low lubricity diesel fuels
- Stabilizes Fuel – keeps fuel fresher and protects against formations of gums caused by oxidation
- Cold Weather Protection – improves diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel
- Corrosion Preventative– Corrosion inhibiters will protect the fuel system from rust and corrosion
- Helps Remove Water – special demulsifiers cause tiny water droplets to come out of suspension/emulsion, so the filter/separator can more effectively remove water
- Contains No Alcohol – avoids corrosion and accelerated wear
- 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 shown in bio content up to B20
