Oil is in good shape. Oil was in for 1 year? I have no idea of any of those fuel adds would impact tbn.

I agree oil held up good. Yes, oil was in 1 year. I would have liked to seen silicon and iron lower.

Not bad. 1 year in a GM engine and the Fe is 15 ppm? That's awesome IMHO.

Si at 17 ppm, figure 5-8 ppm is native, that's really not bad.

Vis very close to 10, decent.

Really a nice report.

Oil is in very good shape. Fe is LOW. What is it with people and these numbers? LOL

Nothing to see here ...move along ...move along.

Maybe we are just the three obvious Privates.

Sorry guys, but not extremely impressed. Just kidding short trips and a wife driving are severe service personified!!! TBN is the only thing I see sitting down there on the low side, but hey it might have made 15k...I don't know about the fuel additives. Wear and viscosity are pretty darn good too!
