A prospective oil supplier sent me the data sheet. I did check the GM website and confirmed valid Dexos1 gen2 licenses for both grades of oil.
To me, the TBN on the 0w20 looks way too low and the viscosity for the 5w30 appears to be incorrect. But these oils are GM licensed and are priced very very low. Should I buy?
