Used by Joe Gibbs Racing in all their unrestricted NASCAR engines. Recommended for engines with clearances under .0025 or applications that specify a 30 weight oil. Although it is a SAE5W-20 it is on the thick side making it very close to a SAE5W-30 oil
This is a full synthetic race oil and the anti-wear additive pack makes it unsuitable for road cars fitted with catalytic converters.
