Valvoline Daily Protection SAE 80W-90 Gear Oil is a thermally stable extreme-pressure lubricant that offers outstanding protection for gearboxes and differentials in passenger cars, light trucks, and sport utility vehicles. Combined with high-quality base oils, our formula’s superior additives help reliably safeguard against severe temperatures, shock loads, foaming, scuffing, scouring, corrosion, and pitting in high load, high torque, and high horsepower conditions. Available in quart-size bottles with a handy cone-top nozzle designed to get into tight spaces, it’s recommended for use in conventional hypoid differentials and non-synchronized manual transmissions where an API-GL5 or GL-4 fluid is specified.
