I do know of Tom, but not personally. He sounds like a great guy from what I've heard. I like to change my oil often because of the dirty conditions I drive in and I want it to cause as little friction as possible. Where can I get oil analyzed, I heard of farmers doing that like one guy said in an old post on the topic, and it seemed like John M. had good things to say about the Delo 400. Is that at normal auto part stores? Maybe that is the stuff for me? I don't know how the price of it compares with the synthetic stuff. As for now, I might as well stick with my quaker state peak performance and a NAPA filter if synthetics are built up to be more than what they are.
