I'm going to change out the tranmission fluid and differential gear oil for my Z. After looking around, I stumble on to a website that tested the Redline vs. Mobil 1 on a C5. They recommended the Redline lightweight "shockproof" 75W80 for the differential. I know that the manual said to use 75W90, but does anyone have any experience with the Redline 75W80?
