try
www.thebestoil.com which is biased however the info on oil is supposed to be independent I think done by SAE looking at shear strenght, cold pour point, 4 ball wear test etc. I know many people who have over 200K on thier cars with regular oil. I prefer synthetics for many reasons listed in other oil threads in the forum. The best test for synthetic oil is to leave a qt outside at 15 below with regular oil and witness for yourself the unbiased info you get when you pour a little of each out synthetic=normal flow, regular=molasses. Which will protect best at cold (even summer) start up where 80% of wear occurs?
