Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid. Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear-even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.

We’ve squeezed innovation into every ounce of Valvoline FlexFill SAE 75W-140 Full Synthetic Gear Oil, the ultimate gear protection in hypoid rear differentials and non-synchronized manual transmissions. Our unique new flexible pouch makes getting into the tightest places to lubricate gears easier than ever and with less waste. The superior detergent package-based formulation contains fully synthetic basestocks and special additives that help protect parts from rust and corrosion while providing exceptional high and low temperature protection and excellent thermal stability, especially in demanding driving situations such as towing and off-roading. It contains an extreme pressure additive for better load carrying capacity, wear resistance additives that assist in protecting gear teeth, a limited slip additive for optimal clutch pack performance, and an anti-foaming agent for better lubrication and service life. Valvoline FlexFill SAE 75W-140 Full Synthetic Gear Oil is recommended for use in axle applications requiring factory-fill or drain-and-fill levels for limited slip performance. Volume: 1 quart.

Union 76 gear oil is a conventional non-synthetic 80W90 formulation designed for all types of differentials.

Redline Heavy Shockproof Gear Oil is formulated to provide lasting protection.

Choosing an automatic transmission fluid just got easier. Valvoline Full Synthetic MaxLife Multi-Vehicle ATF, the #1 ATF product, is suitable for use in 95% of ATF vehicles in operation with US registered light duty applications. And now, it€™s also recommended for most belt and chain-driven continuously variable transmissions (CVT). Featuring advanced additives to prevent the major causes of transmission breakdown, it€™s designed to help prevent leaks, reduce wear and tear, and maximize performance €“ all for much longer than conventional fluids. It has improved thermal stability for longer fluid life, better viscosity stability for consistent transmission operation, and frictional enhancements for smooth gear engagements. Whether your vehicle has a CVT or traditional automatic, Valvoline MaxLife Multi-Vehicle ATF is suitable for a broad range of transmissions including Ford, GM, Toyota, Honda, Nissan, Hyundai, Subaru, BMW, Mercedes, Volvo, VW and Audi vehicles. It€™s specifically recommended for use in the following applications: GM DEXRON-II, DEXRON-III, DEXRON-VI, and DEX-CVT; Ford MERCON LV; Toyota/Lexus Type T, T-II, T-IV, WS, CVTF FE, and CVTF TC. For the many miles ahead, trust your transmission with Valvoline, the #1 automatic transmission fluid brand.

Modern transmissions are better than ever, with more gears to help improve fuel efficiency and acceleration. Greater performance calls for greater protection. Valvoline Extended Protection Full Synthetic ATF features our exclusive Dual Defense Additive Technology for two layers of protection against metal-on-metal contact and thermal breakdown, all while minimizing wear on clutch components. In fact, Valvoline Extended Protection Full Synthetic ATF is 45% stronger against breakdown compared to major brand DEX/MERC oxidative PDSC performance. Proven to maximize transmission life, our patented formula keeps your modern vehicle shifting smoothly, mile after mile, with the ultimate protection you can only expect from Valvoline, the #1 ATF brand.
