Advanced Full Synthetic 75W-140 Gear Oil

The Valvoline Advanced Full Synthetic 75W-140 Gear Oil is engineered to provide superior protection and enhanced performance in hypoid rear differentials and non-synchronized manual transmissions. Key performance benefits include 1.5X better gear wear protection and 1.5X stronger extreme pressure protection when compared to Valvoline Daily Protection 85W-140, as measured in ASTM D-7452. It also provides 30% better protection against towing and heavy loads. The full synthetic base ensures excellent operation across a wide temperature range, from -50F to 300F, offering cold temperature fluidity and high temperature performance. Additional additives, such as a limited slip for optimal clutch pack performance and an anti-foaming agent for improved lubrication, contribute to its overall effectiveness. This gear oil is recommended for conventional rear axles and non-synchronized manual transmissions that require extreme gear lubrication under high torque, high speed, high load, and high horsepower conditions. Its formulation also includes corrosion inhibitors and safeguards against impurities, oxidation, and thermal breakdown, ensuring the longevity and smooth operation of drivetrain components. The advanced full synthetic formulation helps prevent noise and reduce chattering, while protecting gear teeth from premature wear, contributing to durable, smooth, and reliable shifts. The Valvoline Advanced Full Synthetic 75W-140 Gear Oil meets or exceeds API GL-5, Ford M2C-192A, GM 12346140, and Chrysler MS-8985 specifications, where GL-5 SAE 75W-140 gear oil is required. The addition of a supplemental friction modifier is not necessary for most applications.
