As far as I know, we don’t have corn free gas as an option. I am headed down the hill in an hour to drop off daughter and then to the gas station to see what we have available. At Denver altitude, we don’t get full power out of any engine (car or otherwise) that isn’t turbo charged, so the available octane ratings are lower because we don’t need the higher numbers necessary at sea level to make most cars run as designed.

And being so close to the smog laws in Denver, I believe ethanol is in all the gas, at least in the winter, when inversions trap the smog down low.

I just hate the idea of running 100LL due to fuel cost and maintenance cost (time and money) for the engine.

Maybe I should just hang a PT-6 on the front.
