SCHAEFFER'S OIL SUPREME GEAR LUBE SYNTHETIC PLUS SAE 75W-90
This ain’t your grandpa’s gear oil (unless your grandpa ran moonshine in a '68 Chevelle). Schaeffer’s Supreme 75W-90 is a synthetic-blend beast—built for brutal heat, hard pulls, and high-dollar hardware. Keeps your gears smoother than a late-night radio DJ.
Perfect for race cars, tow pigs, and anything else that turns hard and runs hot. It’s got extra stick, anti-wear goodies, and just enough voodoo science to make you believe in miracles.
Drain your junk. Pour in Supreme. Win more.
