Is Synthetic worth useing ? How about Pennzoil / Quaker State conventional oils ? Does Pennzoil cause problms with guming ? I tried to get your show a few weeks ago on this subject. I'm told that Pennzoil yellow is excellant oil.Last question: If you start useing synthetic, can you go back to conventional? Thanks Jim
