I'll run it out of gas if need be, but I'll run an auxillary source for the test if it is that bad. One thing is I drive these things a lot and running 100 octane all the time would get to even me. I can get 87 octane non-ethanol about 3 miles from the house but not sure it would like a lot of that. I've never nothered with octane booster is it effective? Is there an additive that counteracts the ethanols tendency to boil out there?

Thanks for all the input so far guys and I'll update as I figure stuff out.
