Prime Guard Gear Oil, SAE 80W90 5-Gal

The PRIMPG80W905GAL Prime Guard Gear Oil (SAE 80W-90, 5-Gallon) is a multi-purpose GL-5 gear lubricant formulated with sulfur/phosphorous EP additives for gear sets operating under load. Blended from highly refined base stocks and performance additives, it’s designed to deliver extreme pressure protection, strong anti-wear performance, and dependable protection against rust and corrosion, while also providing low-temperature flow (low pour point) and anti-foaming control. It’s recommended for use in passenger cars, light duty trucks, and SUVs where an 80W-90 GL-5 gear oil is specified, with limited slip use noted as top-off only.
