Product Details
Part No. 889785
Warranty Details (30 Day Warranty)
We've squeezed innovation into every ounce of Valvoline FlexFill SAE 75W-90 Full Synthetic Gear Oil, the ultimate gear protection in hypoid rear differentials and non-synchronized manual transmissions. Our unique new flexible pouch makes getting into the tightest places to lubricate gears easier than ever and with less waste. The superior detergent package-based formulation contains fully synthetic basestocks and special additives that help protect parts from rust and corrosion while providing exceptional high and low temperature protection and excellent thermal stability, especially in demanding driving situations such as towing and off-roading. It contains an extreme pressure additive for better load carrying capacity, wear resistance additives that assist in protecting gear teeth, a limited slip additive for optimal clutch pack performance, and an anti-foaming agent for better lubrication and service life. Valvoline FlexFill SAE 75W-90 Full Synthetic Gear Oil is recommended for use in axle applications requiring factory-fill or drain-and-fill levels for limited slip performance.

Product Features:
  • FLEXIBLE POUCH FOR EASIER USE WITH LESS WASTE in tight, hard to reach undercarriage situations.
  • EXCEPTIONAL HIGH AND LOW TEMPERATURE PROTECTION ranging from -30F to 300F degrees for dependable coverage year-round
  • REDUCES CHATTERING AND PROTECTS GEAR TEETH from oxidation, rust, and wear
  • MEETS THE DEMANDS OF CONVENTIONAL AND LIMITED SLIP REAR DIFFERENTIALS where API GL-5 is specified, as well as non-synchronized manual transmissions that require API GL-4 or MT-1 fluid
  • MEETS OR EXCEEDS PERFORMANCE REQUIREMENTS for Mack GO-H and GO-J; API GL-5 and API MT-1; MIL-PRF-2105E; and SAE J2360

Great stuff & flexfill makes it so much easier!
I can't believe it took this long for oil manufacturers to start making these flexfill or easypack packages for gear oil. Gone are the days of fighting to get the bulky oil bottle up around the spare tire or rear end without making a mess! This valvoline 75w90 is excellent oil as well. Have used it for years and always grab some when doing a diff service. This along with some AcDelco friction modifier has the rear end in my silverado working perfect without any chatter. Definitely recommend.

As described. Alittle pricey
Its oil. It did it's job and lubricated.
I would buy this product again.
This product was great. Very easy to use with a pour spout that does not make any mess. All the product is used with no waste. Cut the tip of the spout and start to pour. Great name and great product.
Bottom Line Yes, I would recommend to a friend

As expected
Good quality overall. It would get 5 stars if the threaded opening was compatible with the pump sold right next to it. Glad that it had limited slip additive.
Bottom Line Yes, I would recommend to a friend
Where has the old bag of lube been my whole life!
Seriously, why has it taken eons for someone to put gear lube in a bag. All the pumps, hoses, and hacks to get the lube in the ol rear end just so you can finish the job. The bag made it so much easier. I'll buy whatever brand has it in a bag.
Bottom Line Yes, I would recommend to a friend
