  • Reformulated for improved frictional properties
  • Special detergents for improved lubricity and less detonation
  • Polyol ester base stocks provide more stability and film strength when exposed to excess fuel dilution
  • Each of these products has no less than 2200ppm of zinc and phosphorus for antiwear
  • Each race oil product is a multi-grade, offering 2-4% more power than oil of a similar viscosity - 20WT is a 5W20, 30WT is a 10W30, 40WT is a 15W40, 50WT is a 15W50
  • Improved protection at startup, lower oil temp, cleanliness
