I've seen posts and I myself put ethanol free gas in my mini. Right now, regular gas is $1.50 and ethanol free is $2.79 a gallon. I drive a full size American pickup for work quite a bit. It tells me what my fuel economy is for the last 25 miles, 50 miles, etc. The last two tanks that I have filled up with have resulted in fantastic fuel economy. Over 4mpg better than usual. With oil being at an all time low and ethanol being at an all time high due to sanitizers, I'm thinking that regular fuel is now ethanol free because it's cheaper. 43 states do not require ethanol, but all allow 10%. I'm going to test some tomorrow, but I thought I'd just throw my conspiracy theory out there tonight.
