## Description

Valvoline Advanced Full Synthetic 75W-90 Gear Oil goes where other gear oils don’t. Our patented pouch is easy to use in compact spaces, releasing 2X more fluid with less effort for 3X faster filling vs. traditional bottle packaging using 75W-90 Gear Oil. Engineered for hypoid rear differentials and non-synchronized manual transmissions, the full synthetic formulation and special additives protect from rust and corrosion while providing enhanced high temperature performance and cold temperature fluidity. With 30% better protection against towing and heavy loads, 1.5X stronger extreme pressure protection and 1.5X better gear wear protection vs. Valvoline Daily Protection 75W-90 in ASTM D-7452, it’s essential for demanding, severe-service driving as well as off-roading. Our innovative gear lubricant features a limited slip friction modifier for optimal clutch pack performance, an extreme pressure additive to protect gear teeth and prolong life, and an anti-foaming agent for better lubrication. Protect your gears with Valvoline, the #1 gear oil brand.

Review: Great Gear Fluid without Breaking the Budget! - Valvoline is great rear-end fluid for my Ford 8.8. Added during a recent fluid and differential cover change. WIth the limited slip additive and Flexfill gear oil, my differential hooks up much better and is definitely smooth as butter. The gear oil bags/packaging are very useful but I still used a hand pump/hose to add back the new oil to the differential. Highly recommended for the health of your differential!
Review: Great design & product! - Perfect, used as a maintenance item on a 2019 Ram Rebel as the differential fluid on the truck needed limited slip additive. So far the fluid is doing its job with no leaks. I love how easy it is to fill the differential with the baggy design for the product, brilliant! Great value for the money!
