Hi
I think it is time for me to change the differential oil. I know it uses a "special" GM oil, but I find it to expensive.
Can I use some other oil?

Thanks in advance

Sorry, I'm from chile and I don't speak englinsh perfectly, but isn't rear end and differential the same thing??
Maybe I was trying to say final drive unit oil.

Rear differential. You can use Mobil One Synthetic Gear Lube. It's roughly 1/2 the price of the GM fluid. My guess is 75w-90 but best to check your owner's manual.

Thanks
I've seen the owner's manual, and it says SAE 90 (excluding limited slip diferentials).
It's Ok to use multigrade instead of monograde oil?
