Great product!
Used in my 2020 Tacoma at 50k miles. More metal in the original oil than I expected in the diff . Smooth as silk.

Better gear oil than OEM and a lot cheaper.
Replaced OEM front and rear differential gear oil in my 2017 Toyota 4Runner Limited with Red Line 75W85 gear oil. Toyota specification is listed on the bottle. Differential noise, present since I purchased the vehicle new, has gone away.

No pump will fit the top
C'mon Redline, we can't standardize the tops to fit our pumps and from what I can tell there is no fluid pump out there that will fit your tops of these quart bottles. I managed to make my slippery Pete fluid pump work but I do find it a little annoying that the tops on your bottles are a smaller diameter.You got a good product here but standardize your quart bottles to fit these pumps or how bout an adapter.Good product but you lose a star for this.

Good fluid for 4 Runners.
Great fluid. Used it on my 2019 4 Runner front and rear differentials. Meets all of Toyotas requirements.

Great oil. Got it for my 1991 Mercedes 300TE 4Matic rear diff.
Meets Mercedes spec for 1991 300TE (wagon). Being cheap, I ordered one, which is close to being enough to fill the rear diff. The fill port is hard to get to, so I ended up spilling a portion of it trying to get the bottle into the fill port. Pumping it in takes forever. Ain't nobody got time for that.I had to order another bottle, which showed up the next day. Quick shipping to MD. That was nice.If you have an 80s or 90s Mercedes-Benz 300, buy two bottles. Even if you get every drop in, it's still not quite enough. Probably because of that pesky metric system.
