Alright, I just filled up and put in 9.4+ gal over 214.4mi, giving me about 22.7 rotten MPG. Another thing that makes no sense is that the low fuel light came on before I filled up, and I only put in 9.4 gal and the gauge says I'm filled to the top! I'm going to search for info about the fuel filler neck to see if that could be it, as was suggested, but something seems odd about this problem. FWIW, when I filled up and the pump kicked off I tried adding more with the nozzle at different positions and different fuel delivery speeds and it still didn't take much more. Kind of a normal fill up really.
