it's like saying help! my car costs too much!! i pay $600 a month for 60 months!!
without telling us what car, what options etc..
but since you live in OH i'd imagine you are paying under $2 a gallon, so your mpg maybe under 20, you also have to consider the weather. cold weather means longer warm up times, thus less efficient engine buring more gas. thus your mpg drops in the winter months, esp if you travel short distances..
