I am a typical gas buyer.  I try to get the best gas for the best price so I will shop around before I stop to fill up.  I don't worry too much about the brand as long as the fuel truck is parked out there filling up the stations pumps. I know to be careful with my credit card so no one gets the number and all that worry too.  BUT now, we have to watch out to not buythe E15 gas as it can be a really costly mistake to buy. According to AAA, it can actually cost you a lot more money getting your car repaired from the damage this gas can do, especially if your vehicle was manufactured before 2012. So once again, buyer beware!
