Wow, that iron level is shockingly low. Mine was at 32 after 6500 miles (first oil change on the Cruze). Maybe that's explained by the fact that I have an iron block but yours is AL? But then I would expect to see more AL in your sample, and there isn't much more. Is this a full synthetic oil?
I'm curious. Does anybody else have other ideas? Maybe Chevys come a little tighter from the factory.
