Prime Guard Premium Gear Oil, 85W-140 GL-5, 5-Gal

The PRIMPG85W1405GAL Prime Guard Premium Gear Oil (85W-140, GL-5, 5-Gallon) is a heavy-duty multi-purpose gear lubricant formulated to meet API GL-5 service requirements for gears operating under severe conditions. Blended with highly refined base stocks and additive technology, it’s designed to deliver extreme pressure protection, reduce wear, help prevent rust and corrosion, resist foaming, and maintain performance through oxidation and thermal stability for long service life. It’s recommended for use in passenger cars, light duty trucks, and SUVs where an 85W-140 GL-5 gear oil is specified, with limited slip applications noted as top-off only.
