It might help to put it in perspective. Your EX has a 44 gallon tank, right? So lets say you need 40 at a fillup. So $3.50/gal x 40 = $140. I can buy gas at Arco for $4.13 today. So $4.13/gal x 40 = $165. Only $25 extra per fillup!
Feel better? I thought so. Don't sell her. That would be a grave error.
