I don't think cost is the issue. I think the purpose of the reports is to objectively determine the potential effects of changing oil at various intervals. He's basically being the guinea pig for the rest of us.
I have always thought synth oil at a 10,000 mile interval or dino at a 5,000 mile interval would be fine. Now I am convinced of it.
3,000-mile oil change intervals appears to be for severe-duty vehicles only.
