Valvoline Advanced Full Synthetic 75W-90 Gear Oil 1 QT

The flexi container makes it super easy to fill your differential. Quality oil

I've used Valvoline sythentic oil in many applications for over forty years. Valvoline is a top notch A+ grade lubricant, not some cheapo over-hyped and over-rated snake oil.I used this particular GL-5 rated sythetic (with limited slip additive) in a BMW E36, and it meets or exceeds all BMW requirements. Works great, and better protection than stock 75W-90 when driven hard, towing or in hot environments. Thanks to the limited slip additive, the pos-unit is smooth and gradual, not chattery. The limited slip additive is in the package, no extra costs or mixing required. NOTE: If you don't HAVE limited slip, no problem. The Valvoline limited slip additive is harmless to non-posi differentials, so you can use it in either application without any concern.Finally, a small but significant detail is that the Valvoline container style makes actually putting the lubricant into the rear axle of the BMW very very easy. No hoses or pumps required! Drain the old gear oil from the bottom port. Close it up and retorque the drain plug. Now, open up the top port and squirt the oil in with this squeeze style bottle. Retorque the fill nut, you're done.Works fantastic - didn't spill a drop, and absolutely no hoses or pumps required. A simple no-nonsense solution to what can be a messy problem, and a GREAT synthetic gear oil from a real old-school oil company - one that actually operates real refineries. (unlike so many other snake-oil style gear oils and engine oils, which come from people who don't own or operate actual refineries...I bet you didn't know that, eh? HINT: BMW, Mercedes, Audi, Amsoil, Royal Purple, etc. do NOT refine anything. They SPECIFY, and then real refineries make their product for them.) Just personal taste, but I'd rather buy from the source, as opposed to a vendor who bought it for me (with markup included, of course - plus advertising and marketing)Go Valvoline - you can't go wrong.

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.

Works great, great convenient squeezable container for axle fills. Would buy again.

These soft packs are far better than the hard plastic bottles for getting in nooks and crannies under a vehicle. The nozzle is still hard plastic FYI. Valvoline makes quality gear oil, but make sure the specs meet your vehicle’s requirements.

Great product and the package is amazing! No more struggling with cheap hand pumps to get the gear oil in. Just clip the spout and squeeze. Should be eligible for a Nobel peace prize!

I’ve recently did a fluid change on my differential in my Mazda Miata. the gear oil seem to be pretty good without any issue. I did not notice any change compared to the OEM fluid. Overall, it seems to be pretty good.Because the design of the bottle you’re going to need to use a fluid pump to extract the fluid from the bottle into your gearbox I wish in the future they will change the design of the bottle and use a squeeze type design so it’s much easier to change fluid.Overall for the price is a good deal I would recommend it

I used this on my 2025 Evolution cart's differential. Ten minute job, zero mess.Diff is much quieter now. Service at dealer would have cost hundreds $.Will buy again.
