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: Nicely replaced the fluid in my 2000 excursion - These Valvoline lube packs made refilling my differential clean and easy. My Ford excursion had over 220,000 miles and it was time to change the differential fluid along with transmission fluid and oil and transfer case fluid. After this lubrication service I was pleased to receive a 15% boost in fuel economy above the normal 10 and a half miles per gallon I had been getting.

### ⭐⭐⭐⭐⭐ Great design & product!
*by C***E on December 31, 2025*

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!
