Gear Oil, 85W-140 GL-5, 1-Gal

PRIME GUARD PG85W140GAL Premium GL-5 Gear Oil is a heavy-duty 85W-140 gear lubricant formulated for API GL-5 service, built to handle extreme-pressure conditions in differentials and gear sets. Blended with highly refined base stocks plus a sulfur/phosphorous additive system, it delivers strong anti-wear protection, corrosion resistance, and anti-foaming performance, while maintaining stability for long service life. It’s the kind of oil that shows up to work when the gears are under stress—so they don’t have to.
