That's what I'm running. Problem is, my plug looks dry and burnt every time I check it. Just what kind of conditions should it be in order to have an accurate reading? Idle? Should I gun it before checking it? Tried three different tanks of gas, three different octanes and the results the same. I add oil to the mix by the capful until I check the plug and it eventually shows a little oil on it. But seems like I can't achieve the Goldilocks ratio. Just goes from bone dry to sopping wet.

Pretty sure that's an air / fuel adjustment.

The chart below will let you compare your plug and decide if you need more fuel or air. Sounds like you need more fuel.
