Good day all
What gear oil do you guys use for your Avalanche?
Owner's manual says to use 80W90 in the front diff, and 75W90 synthetic in the rear.
Do I need to be concerned about the GM specs (a.k.a. 'grape juice'), or will any good axle lubricant do the job?
Thanks for any testimonials that you may have
