Racing oils provide more wear protection than motor oils for passenger vehicles, however, these products contain fewer detergents and are not suitable for street use Details: Sold as 1 Gallon 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 2200 ppm of zinc and phosphorus for anti wear Each race oil product is a multi grade, offering 2 to 4 percent 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 Remember to change these oils more frequently than regular motor oils Popular in Top Alcohol and Pro Mod classes, AHDRA Nitro bikes and Blown Alcohol Tractor Pulling Can be heated to evaporate fuel dilution and reuse Phosphorus, Avg PPM 2350 Zinc, Avg PPM 2250 SAE Viscosity Grade 20W60 Vis at 100 degrees C, CSt 25 Vis at 40 degrees C, CSt 197 Viscosity Index 158 CCS Viscosity, Poise, at degrees C 30 at neg 10 degrees C Pour Point, degrees C neg 40 Pour Point, degrees F neg 40 NOACK Evaporation Loss,1hr at 482 degrees F (250 degrees C), percent 6
