Description
Castrol Hypoy Light EP 80W was a mineral-based, extreme pressure gear oil for lubricating manual gearboxes and other manual transmissions, particularly where an API GL-4 specification was required. Its “Hypoy” and “EP” (Extreme Pressure) designation indicates it was designed to handle the high pressures found in hypoid gears, and “Light” suggests it had a lower viscosity.
