Went to AutoZone to get gear oil for the front diff and all they had was Mobil 1 75w90 LS. No other Mobil 1 gear oil . Is that okay for a 2006 Escalade AWD? Or should I continue down the street to O'Reilly?
Yes... use it with confidence. Your front and rear diffs will love this stuff. My GM's love this exact same product.
BTW, this is one of the best gear lubes on the market.
