[s-cars] Synthetic oil?

[Joe Pizzimenti]

Not to bring up this old debate, but I always thought that you should
use the heaviest oil that you can get away with in order to provide
maximum protection against bearing wear and other metal-on-metal
contact.  I just don't see a zero-weight oil doing that.

Joe, 15W-40 nonsynthetic Evo (against all recommendations) and still
ticking, Pizzo
