I just bought a car with 72K on the clock. 00Z28 with 3.23s and auto. I'm changing everything I can think of.
-flushed coolant with green stuff
-plugs/wires
-engine oil
-rotors/pads/flush brake fluid
-fuel filter
Trans fluid was changed recently so I left that alone. Now, I'm going to change the diff fluid. What's the recommended oil to use?

I used Mobil 1 75W90 with a tube of diff. lube.

I use GM's gear oil with there anifriction additive. Also are you going to run the green antifreeze after the flush?

Yes, I'm running the green coolant right now. I flushed it once with Prestone Flush and distilled water, then flushed it again with just distilled water. Then I added the 50/50 mix of the green stuff. It says it's a new formula that can be added to whatever coolant. So that's good since I'm sure there is some tiny bit of orange left somewhere.

Is that new prestone compatable with our aluminum engines??

I am running the Moble 1 in the rear with an additive from GM. I noticed no difference.

It says compatible with other coolants so if that's true then it has to be compatible with whatever those other coolants are for. I'm sure if it wasn't, there would be a story about it on here. It's still your basic green stuff.

Check out Amsoil 75w-90 synthetic. Dont forget to get a bottle of GM Limited Slip Additive.
