This is the first analysis (Blackstone) after purchasing this car with 39K on it. Oil changed after 1 week of driving. 90%+ highway miles, average 800-1000 miles per week. Your thoughts? Thanks! Comments: The universal averages show average wear for the Audi 2.0L Turbo engine after 5,400 miles of oiluse. You ran your oil 5,239 miles and all of the wear metals read below those averages. They were also inbalance to one another, indicating normally wearing parts at 46,387 miles. The high sodium is likely fromadditive in oil that was in use previously. Since potassium and wear were low we doubt the sodium is fromanti-freeze. The TBN was 6.7, lots of active additive left. It's almost gone when it reads 1.0. Oil viscosity wasin the SAE 30W range. Nice wearing Audi!
