I was just reading some EPA testing mumbo jumbo and it made me think about the gasoline we put in our tank. Some of us could really be benefiting from 100% gasoline where others are getting a blend of gasoline and ethanol which is proven to have less BTU resulting in less power and economy. I have been using 85/15E and getting 41.5 avg per tank. I am wondering if I switch over to 100%, which I will have to seek out around here in Houston, will it bring my mileage up any and how much? What blend of gasoline are you using?
