The Amoco (now BP) gas station at Four Corners in Jacksonville has the cheapest gas around Baltimore County. Jacksonville used to have more expensive gas being a small town set 20 minutes from Cockeysville and Timonium. But lately their prices have been considerably lower. It's out of the way if you don't live in Jacksonville but I have friends out there so I'm usually out there every weekend and get gas there. I have never had a problem with the service at this gas station and I think contributing to that is the country setting of Jacksonville. I love getting gas at this BP because I can be filling up and just look around at the nice country town and the intersection that is always filled with activity. If you want cheap gas, go to the Amoco in Jacksonville. By the way, BP is proven serve better and more efficient high grade gas.
