Well I went on the trip and did about 300miles and had an average of 25.6 MPG but before the tripI put in 2 bottles of CRC fuel system cleaner/guaranteed to pass emissions. I usually fill up with BP gas but after the trip I filled up with Mobil gas, wenton a trip of 82 miles round trip, filled up, and my MPG was 27.3 MPG. So either Mobil gas is really good or that CRC stuff was taking effect.
After the tune up ill see what the MPG is and have to test out BP and Mobil gas.
