Anyone run Premium fuel or Octane Boost? Improved performance/mileage or waste of $$.

JaxDad,
I realize that. Just being a bit sloppy. :) I was including various situations in one set of rounded numbers: towing/not towing, generator use, different seasons, etc. But high 7's to 7 is about 10%. I guess I should've said low to mid 7's on the ethanol junk and from high 7's to low 8's with real gas. That would definitely be a more accurate statement. :)
My highest MPG ever, on a tank of real gas, occurred on a long day trip in the Fall (no generator, no A/Cs, not towing the minivan and driving mostly level terrain) and the rig returned about 9.2 MPG over the 300 mile round trip.
Unfortunately, I only had the rig about a year or so before all we could get up in this neck of the woods was the ethanol junk, so I couldn't really get really good, seasonal data. To be honest, I didn't expect any MPG drop when they forced the E-10 on us. But sure as can be, once that was our only choice, every vehicle we owned took an MPG hit in the neighborhood of 10%. For the cars, this became obviously apparent without even measuring anything. The "low fuel" warning lights were going on with about 10% fewer miles traveled.
