If you run any weed-eaters or chain saws this is for sure important. (any 2 or 4 cycle)
I would buy some extra gas cans and drive the 20 miles to get the 100% gas.
I already drive 12 miles but this is just across town.
After stopping using the 10% Ethanol gas, I have almost zero carb problems unless something sits unused for a few months.
On these forums I read where carb problems are common.
Ethanol will degrade the rubber parts making them sticky and gummy; even deteriorate fuel lines. Clog injector holes etc.
You can use the additive but I never liked the idea of adding something to correct the additive.
Locally the 100% gas comes in only one octane grade.
