About 2 years ago I changed my differential fluid and used ST synthetic 75w-90. I am coming up on 30k miles since that change. Wondering if anyone can comment on if this is a "good" gear oil or not.
Actually the differential is very highly stressed lube is very important.I’d have no hesitance using it, in fact I have.
My preference would be Amsoil SVG for a keeper car, but in some circumstances, including trying to get an old, dirty diff cleaned out, the WM stuff is probably good enough. Differentials aren’t engines. They don’t have the same hard conditions. They can get wet, they can suspend lots of junk in the oil, etc... but differentials aren’t as much of a failure or longevity concern as some other parts of a vehicle...

No problem using ST gear oil. Unless you have used the vehicle severely, 30k miles is nothing and you can go much further with your present fill.About 2 years ago I changed my differential fluid and used ST synthetic 75w-90.

well done Sir. . . By the time they geaux to change . . .
Even on a small boat … I like a longer trailer so that does not happenOne of the biggest enemies of differentials here in La. is water. 9 out of 10 Cajuns owns a boat. When they launch that boat (mostly salt water) the differential gets submerged in water. Then, their differential is churning up a gear oil milkshake. By the time they geaux to change the gear oil it's too late. The damage is done. Believe me, I have seen A LOT of truck differentials/gears in the local bone yards from ruined gears.
