Designed for everyday use in passenger cars, light trucks, SUVs and vans, the formula stands up to towing, heavy torque and shock loads while helping control friction and heat build-up in the drivetrain.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this gear oil protect gears under heavy loads?\u003c\/h3\u003e\n\u003cp\u003eIts sulfur-phosphorus additive package creates a protective film on metal surfaces that reduces direct metal-to-metal contact during extreme-pressure events. That barrier helps prevent tooth wear and damage from sudden shocks and high torque situations without compromising smooth operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExtreme-pressure additives for shock-load protection\u003c\/li\u003e\n  \u003cli\u003eReduces friction and heat in the drive train\u003c\/li\u003e\n  \u003cli\u003eHelps prevent scuffing, scouring and pitting\u003c\/li\u003e\n  \u003cli\u003eStabilized to resist thermal breakdown under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this oil in differentials and non-synchronized transmissions?\u003c\/h3\u003e\n\u003cp\u003eYes — Valvoline 80W-90 is suitable for hypoid differentials that call for API GL-5 fluids and for non-synchronized manual transmissions specifying GL-4.
