| I like mobile 1 Full synthetic. My Son and I did his 5th grade report / experiment on motor oil today. We tested Synthetic vs. Regular motor oil in a baking test. Kind of new the results before we did it but it was fun just to verify Before -
 After 500 degrees for 15 minutes-
 The regular oil was noticeably darker and more burnt looking, they both started burning off, the regular oil about 3 minutes sooner than the synthetic. In his report he is showing the need for synthetic in a turbo application, coking and burn points.
