Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 12)

Great price.

Purchased to replace old oil in my 4runner. Good brand and quality. I used a small hand pump to install.

I bought this Mobil 1 - 75w90 to change the rear diff fluid in my Tundra. Toyota spec is a 75w85 that is incredibly hard to find, and ranges from $65-$150 a quart (stupid expensive). I did a ton of research, and found numerous testing write-ups. Mobil 1 was a good all-around performance option, and actually runs slightly THINNER at operating temp than some other 75w90 gear oils. In my estimation, it's not a big difference in viscosity from the 75w85 Toyota fluid, so I decided this was a good compromise. It might be slightly heavier than the Toyota spec 75w85, but the truck seems be doing just fine with Mobil 1 and at a very reasonable price. Also used it in my Mazda rear diff and it's doing well there also.

The rear wheel bearing in our 03 tundra when out on a trip @145,000 miles (typical problem) We were forced to bring it to a local-rip-off-shop in Escalate Utah where they changed the bearing but failed to refill the diff. They chased us out of the shop after paying! We disputed the charge to the CC and got our money back. Anyway, after getting home (over 1500 miles.) we checked the rear diff fluid and it was a qt low! So i topped it off, and week alter drained it. All i can say is WOW! it didn't smell burned, it looked just as good the day we put it in! No metal shaving or anything. Still no problems after a few months and another 2500 mile trip! Lesson: If you want you vehicle to hold up against rip off-hack mechanics, fill your vehicles with mobile one. It's an insurance policy!

Worked as expected

Have no idea what it’s doing in there or how well it’s working but I assume it’s doing its job. Got to have it.

Great price for quality gear oil. Used in my 16 Tundra and 14 4Runner. Never any issues and still looks great when I do changes

Ordered 12L and only received 9L
