Red Line LightWeight ShockProof Gear Oil in a quart offers film thickness greater than SAE 75W140 while keeping low fluid friction like lighter gear or motor oils. It provides excellent low-temperature flow and improved cold shifting, and is popular in racing transmissions and differentials; however, its extreme slipperiness means it is not recommended for most synchro applications.
