Re: bad fuel mileage!
I donít think the computer is just a guide. Itís measuring the exact volume of fuel going into the combustion chamber and the actual mileage the vehicle is moving to calculate the mpg.
Itís also important, like someone already mentioned here, to reset your DIC every time you fill up to get an accurate reading of mpg for that tank, otherwise your averaging the mpg over all the tanks of fuel burned.
I have the four with the 6 speed, and my best Highway, long distance drive, was 36.6 mpg. I drive round trip everyday 94 miles, mostly two lane highway with lots of traffic lights in some areas, and I get 30.5 to 31 mpg in the summer and 32 +mpg in the winter. It has a lot to do with driving habits, at least for me, when Iím careful I get the mpg I just mentioned, when I drive without thinking about it or fast acceleration or last second breaking it drops off 4 to 5 mpg.
Anyway, just my thoughts and experience.
