Valvoline FlexFill Advanced Full Synthetic Full Synthetic 75W-140 Gear Oil 1 QT FlexFill

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!

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.

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.

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.

Works great. Convenient and mess free. Smells terrible.

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

Great product for my Durango 2018. Highly recommend

El embalaje fácilita la aplicación del aceite al diferencial, el aceite se ve muy bien en tonalidad y viscosidad. Además ya le hacia falta el cambio a mi unidad.
