[QUOTE="Dewalt03Cobra, post: 16722476, member: 12357"] So I send oil samples of to Blackstone Labs for wear testing which measures oil degerdation, and contamination. I use to get is checked every year with each oil change (less than a 1000 miles a summer). I Bought my car new in September 2002. After 7 years of almost exactly the same results I started doing it every 2 years. No real change, slight increase in wear contaminants which was expected (metals), but no signs of oil degredation. With My job I travel to oil refinery machine shops and one thing I learned from product engineers is syntheic oil does not break down anywear near as fast as conventional oil. How do you think manufacturer recomendations have increased the miles a car can go between oil changes with having much tighter engine specifications and clearences. Synthetic oil is not conventional and doesn't have the same rules. [/QUOTE]
