Re: oil, gas options?
No, just said that the reason for synthetic might not have anything to do with engine life.
I know of three reasons to use synthetic instead of dino (and some "synthetics" have a lot of dino in there):
1) longer change interval
2) increased MPG
3) better flow qualities (viscosity) when cold.
In central Florida, (3) does not really matter, (2) is of interest only to the EPA and for advertising, and I change oil and filter in my other cars at or before 3,000 miles. (1) and (2) were specifically mentioned by MB. Was there something else ?
