Your friend is not the "expert" you thought ;-)

This is because Amsoil and Mobil1 and all the others disagree with him. You see, Amsoil is the best and it makes 0W-20 and 0w-30 and tens of thousands of cars using it are not failing. In addition, UOA for those oils shows very, very low wear...so much for the "molecues cannot stretch" comment.

I would suggest we all pay a visit to BobIsTheOilGuy.com and read the forums on oil there....a lot of superstitions will die if you do...at least they did for me.
