[AT] Synthetic Oil

[John Hall]

Similar story--at work we were warned by the machine manufacturer NOT to 
use synthetic cutting fluid in their machines as it would deteriorate 
the seals. So maybe synthetic oil can do the same to older engines, 
assuming gasket and seal technology has changed.

I've only got synthetic in my son's 4 wheeler--thats what the PO was 
using. Aside from that its 30WHD, 30W low-ash, or 10W-40 in everything 
here. Of course we don't have to deal with very cold temps like some of 
you guys, thats a game changer.
