Performance Formula

Stanadyne Performance Formula® protects your diesel engine and  restores engine performance. The detergency and cetane improver in Performance Formula will help restore fuel economy, increase horsepower and torque. 

  • 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 aftertreatment 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
