Automotive Gear Oil GL4 80W90

Phillips 66® Automotive Gear Oil GL-4 is a multipurpose, extreme-pressure, API GL-4 automotive gear lubricant. It's crafted for use in select manual transmissions and drive axles with spiral bevel gears or hypoid gears operating under moderate speeds and loads. Designed to provide long service life and superior gear protection, Automotive Gear Oil GL-4 excels in automotive differentials operating under diverse speed, load, temperature, and torque conditions. Its carefully balanced formulation minimizes oxidative sludge and varnish formation, reduces wear, prevents scoring damage, and guards against metal fatigue and spalling damage under moderate load conditions. It's also suitable for heavy duty commercial manual transmissions and transaxles where the OEM specifies an API GL-4 quality oil. Features & Benefits

• Excellent oxidation resistance and thermal stability to minimize sludge and varnish formation
• Good thermal durability and extreme-pressure (EP) properties for long gear life
• High load-carrying capacity for protection against scuffing and wear
• Protects against rust and corrosion
• Good foam resistance

Applications

• Service fill of conventional differentials in passenger cars and trucks with spiral bevel gears, or with hypoid gears operating under moderate loads where API GL-5 gear oils are not required
• Service fill of differentials, final drives and transfer cases in some off-highway equipment
• Manual transmissions in trucks, buses and heavy equipment where the manufacturer specifies an API GL-4 gear oil

Automotive Gear Oil GL-4 meets or exceeds the requirements of API Service GL-4.
