I received my OnStar Diagnostic Report today, one month since delivery. I have 95% oil life left. They recommend service at 18,000 miles! COOL!
Uh-Oh, my RR tire is one pound low. Maybe the pressure will rise while the car warms back up in the garage.
I've used 5 gallons of gas, but I bought three gallons just make sure the gas cap and door work ok, but I don't plan on buying gas for a long time.
Thanks GM, thanks OnStar for this Way Cool System!
