Valvoline SynPower SAE 75W-90 Full Synthetic Gear Oil 1 QT, Case of 12

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!

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.

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!

Super form of gear oil / Hyundai 6 speed DTC transmission fluid. This gets around using and contorting tubes and gravity for fluid replacement. This saved a bunch of time. Not only that, but it was much cheaper than the Hyundai OEM oil and had better certifications, and although it costs a little more than other equivalent fluids, their use in traditional bottles is much more laborious and less efficient. This saved a ton of time, effort, and then clean up. Super!!!

The bottle design saved me from having to buy a small hand pump for my transfer case. Overall the fluid is synthetic and at a reasonable price point so it’s a good fluid to use. Of course if you’ve never used gear oil before the smell is normal due to limited slip additives.

Valvoline is a top-notch synthetic differential, 75W-90 Gear Oil, that I used in servicing my 2019 Mercedes GLC300 for scheduled maintenance. This gear oil comes in a 1qt, flexible pouch with an easy fill spigot to fill the differential (front or rear.) The vehicle drives smoothly without hesitation or leaks. I highly recommend this Valvoline Extended Protection Gear Oil.

So easy to use under vehicle. Just squeeze and fill up.

Used these to change the differential fluids in my 2020 Jeep Grand Cherokee. I know it's not the recommended weight but I could care less about the fuel efficient "benefits" of using the lighter weight. Great quality for a great price. Runs great
