Flexfill SAE 75W-90 Full Synthetic Gear Oil 1 QT, Case of 4

Valvoline, 'nuf said, but oh man, did I love the package! So great not to have to have a pump or tubing or anything else to buy or clean up. These bottles are flexible enough to access even a Smart car transmission spill-free, and collapsed during filling like a cheap, recycled water bottle. Will buy this every time now!

Being in the plastic bags, it made it so easy to fill the differential I would buy this product again

I recently used the Valvoline SynPower SAE 75W-90 Full Synthetic Gear Oil for my 2017 Camaro's rear differential, and I am thoroughly impressed with its performance. The gear oil provides excellent protection and lubrication, ensuring smooth and efficient operation. One of the standout features of this product is its full synthetic formulation. It is specifically designed to handle extreme conditions, which gives me confidence in its ability to protect my car’s differential under various driving situations. Whether I’m cruising on the highway or pushing the limits on a track day, this gear oil maintains its integrity and performance. The 1-gallon container is also a great value, providing enough oil for multiple uses. The packaging is user-friendly, with a convenient spout that makes it easy to pour without any mess. Additionally, the clear labeling provides all the necessary information, including specifications and compatibility. Overall, the Valvoline SynPower SAE 75W-90 Full Synthetic Gear Oil is a fantastic choice for anyone looking to maintain and enhance the performance of their vehicle's differential. Its reliable protection and high-quality formulation make it a top-notch product that I would highly recommend to other Camaro owners or anyone needing a robust gear oil.

I use this in my 2013 Fiat 500 MT (Non turbo) and have never had a bad experience with it. The squishy pouch means I can just pop the fill plug on the front without putting the car on ramps and fill it on a level parking lot. (Also, putting a small MT car on ramps is an awful experience, I will do anything to avoid that) Love the squishy packs. Pricing is competitive to my local stores too.

I used this Valvoline FlexFill Full Synthetic 75W-90 Gear Oil for a differential fluid service, and I couldn't be happier with the results. The flexible pouch design makes filling the differential much easier than with traditional bottles, especially in tight spaces where a pump can be awkward or messy. The oil itself is high quality and provides smooth, quiet operation after the fluid change. I noticed reduced gear noise and greater confidence knowing I'm using a full-synthetic lubricant designed to protect against wear, corrosion, and high-temperature conditions. It's also compatible with limited-slip differentials, which is a huge plus. Overall, this product saved me time, reduced the mess of the job, and delivered exactly what I was looking for. If you're servicing your differential or gearbox and want a quality synthetic gear oil with an innovative, easy-to-use package, I highly recommend this product. I'll definitely be purchasing it again for future maintenance.

Worked great like the container easy fill

The bag is a rip-off. Cheaper to buy in a regular bottle and a quality transfer pump. Will work for rear diff, but front diff, transfer case and transmission probably don’t have clearance for the bag. Otherwise no complaints of the actual oil.

This fluid meets or exceeds both API GL-5 and GL-4 specifications, making it safe for a massive range of trucks, SUVs, and passenger cars. It comes pre-blended with limited-slip friction modifiers, which helps eliminate differential "chatter" in limited-slip differentials right out of the gate. However, if your specific vehicle manual mandates a non-hypoid or specialized GL-4 fluid that strictly prohibits limited-slip additives (common in certain synchronized manual gearboxes), you should double-check compatibility.
