Hello folks, a noob here to the BITOG forums, though have been lurking for quite a few years. I have an old Winco Tri-Fuel TF6000E, a hand-me-down, my brother got a new generator. It runs fine and I intend to run it primarily on gasoline, but I want to set it up with the capability to run natural gas from the house in case I have to. Question is... Since NG is a "dry" fuel, and this causes increased valve wear according to what I read, is this a reason to find a special NG oil? Or, as little as it would be used, just nothing to worry about? Right now, it's running Synthetic 5W-30 year round. The dedicated NG oils I have found online also tend to be higher viscosities than regular engine oils.
