60 WT SAE (20W60) For supercharged alcohol engines like NHRA and IHRA Top Alcohol and Pro Modified classes.


2 WT SAE (0W2) Used for NHRA Pro Stock and Pro Stock Motorcycle Oil (1.7W), as used by many of the sport's top teams for extremely tight bearing clearances only. Use only at oil temps under 150øF.


5 WT SAE (0W5) Used by top NHRA Stock and Super Stock, and Pro Stock teams looking for an oil with very low viscosity but slightly more durability than other brands at this weight. Used by NHRA Pro Stock teams for durability and ring seal in warmer climates. Excellent ring seal, yet low parasitic losses. Use only at oil temps under 150øF.



10 WT SAE (0W10) For drag racing and circle track qualifying where the lowest internal friction is desired. Many drag racers run this oil for 10 to 12 passes before changing, with no sign of shear or loss of viscosity. Popular in NHRA Competition Eliminator. Used by many NHRA Pro Stock teams for dyno testing. Much longer drain intervals than competing brands at similar viscosity. Also used in Jr. Dragster engines.



20 WT SAE (5W20) For drag racing, circle track qualifying, and racing engines designed for low-viscosity oils. Many drag racers run this oil for 10 to 12 passes before changing, with no sign of shear or loss of viscosity. Popular with bracket racers looking for extra performance.



30 WT SAE (10W30) Suitable in well-balanced racing engines for sustained high-speed use where low internal friction is desired. Popular in bracket engines, 355 Sprint Car engines, and World of Outlaw 410 engines.



40 WT SAE (15W40) For use where temperatures may be high and when a wide range in RPMs and speeds will be encountered.



50 WT SAE (15W50) For use where extremely high temperatures may be encountered and when engine durability is the primary concern.



60 WT SAE (20W60) For supercharged alcohol engines like NHRA and IHRA Top Alcohol and Pro Modified classes.
