Super Tech Full Synthetic Gear Lubricant SAE 75W-90, 1 Quart

Not paid to write this review. this is likely same as any other name brand gear oil and is full synthetic. I pour these into a larger gear oil gallon plastic container then use my compressed air and drill a hole in the top of the jug and drill a hole in the cap and slide a tube that fits into the hole in the cap securely (add hot glue if its loose) then start slowly but use the compressed air in the other hole and itll push the fluid out of the bottle at a nice rate and completely eliminate the need to use the stupid hand pumps. works great. keep the bottle you modified one for ATF, one for gear oil etc. No need to really rinse it out of oil fluid as long as they are in the same family (gear oil / ATF etc) a tiny bit of like 75-90 mixed with 80-140 doesn't matter. Just as long as it isn't half full. Works with ATF / Gear Oil / Probably coolant but never tried. I never use these bottles to actually fill from.

it's so handy to be able to hop on your phone when you realize oh my goodness I have to take the differential pan off and oh I don't have the differential fluid. Great price awesome delivery. I use this Walmart delivery service all the time and these products are great

I have changed differential fluid on most of the cars I've owned and have always felt that it's better to follow shorter service intervals than manufacturer recommended mileage and time. They want to get you into repairs for neglect imo. SuperTech products are a great value for the person who likes to do their own maintenance. Comparable to other reputable brands and packaged well. I used a pump to get this gear oil into my differential and it was one of the easier things I've ever done on a car. It would be nice if it came in pouches though as that would make the work much much easier to do.

Quality rear-diff gear oil. A bit less expensive than most other brands. I just use it as an intermediate flush before refilling with Mercedes OEM-approved gear oil.

Great oil woks great no reason to spend more money on expensive brand names this stuff is just as good

Good gear oil for half the price of the major brands... what's not to like?

The price and value are tremendous thanks again Walmart!

Stuff seems to be high quality and worked great to ensure my differential was full and ready to go.

super tech brand is noticeably less expensive than other name brands, quality is good

Main compliant: because of the handle, the bottle curves in to an extent that it interferes with the hand pump that most of us use to actually fill a differential or transfer case. You can insert it, but it sit at an angle and can't be screwed in/secured. I had to transfer the oil to a container from a different brand to use the pump. Please change the bottle design! Otherwise, well recognized as good oil and good value for price.
