I just found this site a few days ago and have already found out lots of useful information. I bought a sure drain valve from fram and just installed a few hours ago. I have always used castrol motor oil , i guess the commercials with the scientist running the motor without oil sold me. It seems alot of people here run synthetic, as for me ive always changed oil to synthetic only before a long trip. What do you'll think of the sure drain and reg. castrol oil.
