The synthetic oil (Hydrotex) I sold dissipated heat much better than conventional oils. My truck ran noticeably cooler in the summer and accross the desert. It is not labeled for aircraft use, but..... I used the partly synthetic oil available in 1989 in my 1988 Escort for over 255,000 miles and when the pistons broke from fatigue, I almost reused the old bearing inserts because they were still in such great shape.
