what are your guys' opinions on break-in oils?? i recently read an article in street rodder abouth that, they were talking to 3 diff race oil companies, most of which recomment breaking in the fresh engine with race oil because it has higher levels of zinc, an excellent anti-wear agent or diesel/mineral oil, which also have hi levels of zinc. new standard motor oils have less (600 ppm) of it because of pollution, these are the oils that meet the most recent ASE standards. but then again, some of them said the regular 10w30 was just fine. hogwash or smart????
