First and probley only UOA I will do. I wanted to make sure the oil was holding up to the Ethanol as every time I change the oil it just reeks of E85. The car is raced frequently so Im suprized by the good wear numbers as I expected much worse. As for the sodium I have been a frequent Rotella or VR1 user so not sure if thats a additive in VR1 or not. The car has head studs but runs a decent amount of boost so would not be suprized if a little coolant found its way in the oil either, but I have not noticed any coolant being pushed into the overflow tank or coolant loss.
