Thanks for reminding me to update Puregas for the ONLY place that sells 87 E0 in the area - or I'd say region. There are a bunch of forest / remote folk who bite the bit to only get E0 premium at its premium price. If you don't need the octane its a complete waste. Unfortunately the fuel depot is out of the normal way.
I run E0 regular in the generator (used daily in the winter), the log splitter and ATV. I tried a tankful in the pickup and , yes, I monitored the results. I gained fuel mileage but it was a break even for E10 when all was said and done at a $0.30 increase for regular E0. I won't get into the political side but if the fuel stop was closer I'd use nothing but their stuff.
