I just bought a 2004 HCH and just put in my 1st tank of gas. I put in 13.234 gals and had 480 Miles. Which is only 36mpg but the odometer said I averaged 44.2. What is up? Also what is the size of the fuel tank? It says it has a 13.2 gal tank but I put in over 13.234 gals and had little bit less than 1/4 of a tank and had just turned 3 green bars.
