i have a 2003 accent with just over 22,000 miles on it and over a year and a half ago the gas mileage decreased to the point of jam dropping. the worst we have gotten is 14mpg and the best we have gotten is 20mpg when driving in town. have taken to the dealer 5 times and they cant seem to find anything wrong with it and told me that i must tow things and dont know how to compute gas mileage. hahaha. when i first bought the car we were getting around 30-35mpg in town and around 40mpg on the highway. the car sat for eight months while i went away to school but was started and run by my parents. just had the oil changed last week and the tranny oil is black and smells burnt, the other thing that bothers me. please if anyone has any feedback i would be very greatful.
