Looking for opinions on Mobil One gear Lube

[Bob R]

So would it be ok to use Mobil One 75-140 wt. synthetic lubricant on an open rear end? Thats what I just did. Now I wonder if I should drain and refill with 75-90.

What do you all think.

Thanks,

Bob

The 75w-140 will be fine. My owners manual specified both depending on which page you looked at and limited-slip was not an issue.
