Be careful Rich that you don't mix the non-ethanol fuel with the "E-10". It can and will cause you grief, by way of separation with methyl-tertiary-butyl-ether.
As far as the octane goes, there seems to be a trend towards higher octane....when it comes to length of time stored. Although there is not any performance to be had {with motors that do not need the octane}, there is a safety margin with octane degradation. I would prefer to see you buy fuel at a high-volume, high turn station, rather than be brand selective. Also, avoid filling at any station where you see a delivery truck filling them up. You don't want the "remnants" of the bottom of their tanks.
On a side note...we are seeing ethanol contents ranging from "0" to an astounding 22%! Talk about trying to keep these motors running consistently is a chore.....:blink:
