Yes, I ran an hour meter for a while, then switched over to the vapor.  No, I'm sure I switched up my fuel cans since my generator was burning race fuel!  My cylinder was still in great shape before this last weekend.  Decent compression and no wear when looking at the piston thru the intake and exhaust.  So far I'm impressed with the Amsoil Dominator oil.  I've increased my ratio from 50:1 to 40:1 to make sure I have good lubrication.
