Can anyone direct me to a TSB or paper from Chevrolet that says something to the fact that it's OK to put 0w40 Mobile One oil in earlier model C7 Corvettes.
I remember reading that Chevrolet now requires the 0w40 weight oil in all the C7 corvettes. Also I would like to get the new Oil filler cap that reflects the 0w40 oil requirement, Who might have the part number for that. This would be a big help in convincing my dealership of the change.
Thank You for your help
Thanks very much for the reply It's just what I needed. Also I did a little search and came up with the part number for the Mobil One Oil cap.
Thanks again
Pete
