We've got a 2000 Odyssey that seems to have a problem with the fuel gauge stuck on full. We filled it in Frisco, CO, drove four hours in heavy, slow traffic on I-70 to get home (approx. 82 miles), and noticed that the gauge was still on full. With a fairly well-loaded down car we get about 20 MPG, which would be about 4 gallons used on a tank that fills at around 17, so by my calculations we used about 1/4 tank. I know sometimes the fuel gauge will drop all of a sudden to "catch up" with the actual fuel consumption, but our gauge hasn't budged. Has anyone had a similar problem?
