There is about a 5-7 cent a gallon difference in NC for E10 gas. When you say 25 cent difference is that E10, E15? I don't think our engines are rated for use of more than 10% ethanol blends/
Ethanol has 34% less energy than gasoline. So any ethanol blend will result in worse fuel economy in proportion to the amount of ethanol in the fuel. In the case of E10 that would be up to 3.4% worse mileage. Whether or not that works out economically in your favor depends upon the savings over lost mileage.
In NC when fuel is $3.85 (without ethanol) vs $3.80 (E10) then I'm only saving 1.2% while getting 3.4% worse mileage so economically it makes sense to avoid E10.
There are other potential long term drawbacks to using ethanol in your vehicle but Jeepers aren't the most gentle users of vehicles so YMMV.
I vote no to ethanol and avoid fuel stations that indicate its use.
