Anyone use the REDLINE 75W85 gear oil in the rear differential? It is the only 75W85 I can find.
The REDLINE container does specify MB235/x but not MB231.1
The website for the product however DOES include MB231.1, who to believe?
Last thing I want is to screw up the differential.
Alternately, do you know of a source for the 231.1 oil?
