besides the physical calculations, (spark plugs, air filters, o2 sensors) alot of the mpg you get are reflected on the way you drive. If you baby your car and ease on the gas then you will get significantly longer distances out of one tank of gas, rather than just slamming on the peddal. You dont have to floor it to get up to speed, it took me awile to get used to not hammering down on the pedal casue i had a dodge neon with absolutely no acceleration and was nearly rear ended on every freeway. My solution, fix that sensor, check your air filter, spark plugs, etc. and if your still not getting higher mpgs, then you might wana have the car looked at cause theres definatly a major problem then. I get around 19-20 mpg average. I drive about half the time in town as on the highway and floor the gas about half the time so it weighs even.
