Thee days, even racing gas(110) might have ethanol added.
You can always "wash" your gas to get rid of the ethanol - Eth is (quite easily) water soluble. Get a suitable container, fill to about 2/3 volume with gas, top up with clean water, (some recommend distilled water, but it's not really required) cap and shake well, let settle, decant the water layer that will settle out, repeat until you're happy. You end up with "clean" gas with little or no ethanol left in it. Depending on the blend, might take 3-4 washes to get it to the point you prefer, but other than that detail, easy-peasy...
