Really think any good quality oil syn/dino is fine. engine life is based on maintenance/driving habits and luck IMHO. I use the expensive redline in all three departments. The cost is not important to me, as i can wast money on all sorts of useless crap. Redline is a placebo to me, it makes me feel better even though i really don't know if its doing my engine any extra good.
