getting ready to do some maintenance to my 02 silverado 2500.my question is,what fluid do you guys use in the front ??

 

I replaced mine with Mobil 1 75w-90.

 

I talked to the dealer and they said to use 80w-90 non synthetic ?? how much fluid did your 2500 hold ??

 

I don't remember how much, it has been a year or so ago. I think I bought 5 quarts to do the front and rear, ended up take a quart or two back. When I first got my truck I replaced all fluids in it, I bought all the fluids from the stealer (dealer). The dealer sold me 75w-90 for front and back, cost $17/quart, and it was synethic.

This is the oil they sold me, but cost $17 in 2000.

 

thanks for the replys.I think i'll use the mobil 1 75w-90 also.that GM oil is way over priced!! LOL

 

I use Amsoil 80w90 synthetic in mine but I think you will be fine with Mobil 1 75w90.

 

how much auto-track fluid does the auto-track transfer case hold ?? i'll be changing that as well.

 

front diff. - 3.5 pints (1.75 quarts)
rear diff. - 2.7 quarts
t-case - 2.4 quarts

I check my service manual after my last post.

 

you guys are great,THANKS !!!!
