Wile on our trip to Florida and back I checked the gas milage on our 2019 Grey Hawk 29mv. After several stops and checks I was getting 9.5 to 10 mpg driving 60 to 65 mph. I noticed in Tennessee and Georgia Buc-cees has non ethanol or 100% pure gas. Although the non ethanol gas is about 25 cents higher in price the results were amazing. My fuel millage on my first tank of non ethanol gas was 12.7 mpg. Second tank was 13.2. Has anyone compared no ethanol gas with ethanol added gas and was your findings the same as mine?
