MPG has been a real disappointment. Most owners talk about getting 26 easy, up to 29. I get 21 and I am not yet sure why. I have replaced both the fuel filter and fuel pump. I suspect the four years it sat up just did some more damage somewhere that I have not yet found. the gas tank itself may need a serious derusting process. No mods aside from a dark tint and moving the spare to behind the passenger seat, giving me a giant trunk space for my aquarium water.
