Valvoline Flexfill SAE 75W-140 Full Synthetic Gear Oil 1 QT, Case of 4

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!!!

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.

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

I used this 75W-90 gear oil in the differentials in my Subaru Outback and Forester. It’s Valvoline, so you know it’s good. Plus it was easy to pour. Should be good for another 50k miles.

Works great. Convenient and mess free. Smells terrible.

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

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.
