- Excessive heat makes oil evaporate (switch to thicker oil with lower volatility) and sludge on engine parts (ditto.... plus change to synthetic)Well somebody must have had a problem with excessive oil consumption. Anybody care to share the common cause of this?
Or 4 each totally toasted rings!If its burning oil, you can use any. For that rate of consumption synthetic will just make it worse. 2 qts in 4k miles has to be a leak in addition to the rings. :biggrin:
