The difference between regular and premium is 0.20. 20 gallons of premium is going to cost you $4 more than 20 gallons of regular. In the big picture, is that really an issue? Buy one less coffee or snack during the week. I just don't get when people make it like premium is this major expense compared to regular. That was one of the first things my parents would ask me whenever I got a new car when I was younger. That's when it was $1.50 for premium. It would have been a $4 dollar difference then too. Just my opinion...
