Valvoline Axle Oil 75W-90 LS is a premium fully synthetic axle oil specifically formulated for passenger cars and vans equipped with limited-slip differentials. This specialized lubricant provides the precise friction characteristics required for smooth and reliable limited-slip differential operation, eliminating chatter, noise, and vibration during cornering and low-speed maneuvers.

Limited-slip differentials require a lubricant with carefully adjusted sliding properties to balance the friction between the clutch plates and the gear set. Valvoline Axle Oil 75W-90 LS is engineered with advanced friction modifiers that deliver this precise balance, ensuring consistent limited-slip performance throughout the entire service interval. This prevents the common issue of differential chatter that can develop with conventional gear oils.

The fully synthetic base oils provide excellent protection across a wide temperature range, from cold-weather startups to sustained high-temperature highway driving. At low temperatures, the oil flows readily to provide immediate lubrication and smooth differential operation, while at high temperatures it maintains a strong protective film that shields hypoid gears and bearings from extreme-pressure wear, pitting, and scuffing.

Key benefits include outstanding wear protection for hypoid gear sets under heavy loads, excellent thermal and oxidative stability for extended service life, reliable corrosion protection for internal components, and effective foam resistance. The oil also exhibits excellent seal compatibility, preventing leaks and maintaining proper fluid levels.

Valvoline Axle Oil 75W-90 LS is recommended for nearly all limited-slip differentials where SAE 75W-90 hypoid oil with adjusted sliding properties is specified. It is the ideal choice for performance vehicles, SUVs, and vans where precise traction control and smooth differential operation are essential for driving comfort and safety.
