Gear oil viscosity f/r diff ?

[2k3T4R]

Hi folks! Is it okay to use 75-90w when the manual calls for 80-90w gear oil? Mobil1 gear oil is only available in 75-90w and the rear pumpkin calls for 80-90w and front calls for 75-90w. Are there any other synthetic gear oil that is available in 75-90w weight?

absolutely fine.

I agree. Used M1 also. Not an issue.

I would stick with what the manual says but I'm kinda picky about that, but with suck a small difference you wont have a problem
