[s-cars] Synthetic Oils

>...from the cleanliness of the oil that came out, I don't know that
changing it is worth it.

At 130K miles the oil that came out of mine looked gross and smelled putrid,
so I'm glad I changed it.  I used MT-90 and think that shifting got slightly
smoother.  I don't live in a particularly cold climate so can't comment if
the cold weather behavior is any better or worse.
