Improve fuel economy while increasing horsepower

Stanadyne Performance Formula offers all season protection for your diesel engine and restores engine performance.

Performance Formula - All Season Protection

Stanadyne Fuel Additive - Performance Blend All Season


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 also be used with Bio Diesel Fuel up to B20 (20% bio content approved), increased water separation shown in bio content up to B20

Available Product Numbers and Sizes include: 38564 (8oz./237ml); 38565 (16oz./473ml); 38566 (64oz./1.9L); 38567 (5gal./19L); and 38568 (55gal./208L)
