Try finding the place that sells racing fuels, United Oils here in Boise carries at least 3 different levels of octane and no alcohol. I mix the 110 leaded with the 87 unleaded without alcohol, one gallon racing fuel to every four of the cheap stuff. This gives me a 93 octane without alcohol. Works great for the work and shopping etc., on the road, it is Chevron and it's highest octane sold whenever possible.
A tank of the 110 does make a noticeable power level increase, but at $8 a gal, too expensive for me! I think it makes the higher compression in my bike with it's stage IV state.
