I'm amazed (and more than a little embarrassed) at how I've turned something as simple as filling crankcase and gas tank then pulling on a rope, into a major deal. I am the guy all those youtube folks make "break in your generator the RIGHT way" videos for. I didn't know break in was a thing. Now I'm trying to decide whether to put Marvel Mystery or Lucas oil conditioner, in the spark plug hole before my initial start up. I live in a state that won't let me buy non-ethanol fuel, so that was another couple of hours of pouring over the wisdom of internet wizards. I'm curious what is actually relevant prep for keeping this Inverter/generator happy for many years?
