what oil to use

Do some google searches and see what everyone is saying about Frams. I just did a few different searches..."how fram filters are made", "fram filters good or bad" and a couple other searches and found tons of car sites from LS1 sites to Kia sites about Fram and issues and horror stories. Here is a motorcycle guy who cut the ends off a bunch of filters and shows the inner workings http://www.tobycreek.org/oil_filters/index.shtml. Check out all the filters he cut open on the left.

I dont have anything against Fram or have they ever cause me any problems that I know of, but after having my engine builder tell me to stay away from them and reading everything I have on the web I wont ever personally use one.
