right now I am not washing gas (again only did that for 30 or so gallons of gas last spring) I am just using pumped E10 from any normal gas station.

I can not advance the timing any more without damage to the engine.
I don't understand. You ping on E10, but not on non-ethanol fuel. Is there a difference in octane?

So the only thing you were testing on washed fuel was mileage? And you noticed no pinging when you did?
