i get exactly 20.3 miles on the highway crusing at 70-80. the stock gauge isnt accurate at all, it shows me half full when in realityn its closer to 75%.
not sure if this has anything to do with it but the car sometimes smells like it is running hot. not sure if you know that smell but it is a certian smell
Anyways the car is not running hot. I was thinking it might be the exhaust but could it be something with the gas?
could the maf be really dirty? if so is that hard to clean?
When I bought my car a couple of years ago I was geting terrible mileage. A tune up at the dealership cured the problem and I get 16-17 in city driving and 22-24 on the highway depending upon how fast I drive.
My guage isn't terribly accurate, so I record my gas purchases in a notebook and go by the trip odometer to judge when I need to refuel. I have gone 340 miles between fillups on long road trips.
