Castrol AP Gear 80W-90 is a multigrade gear oil fortified to meet the requirements of API GL-5.
Its primary use is for hypoid gears featured in automotive differentials but is often specified in highly loaded spiral bevel or planetary gearboxes on offshore installations and onshore drillling sites.
Advantages
Good thermal/oxidation stability eliminating deposit formation that thickens the oil.
Superior low temperature fluidity providing smoother operation in cold start conditions.
