I think you are in the ball park of mpg.
It depends if you are talking city or highway driving.
I got a 97 and on the average I get about 15-16 city and 20-23 highway.
A little lower during the winter months.

Hey! Wayner1011! Keep in mind that the 96's had smaller tanks than the later years. And if Ya be in Hamilton in January-the fuel economy will suffer! More warm up time,cold tranny and rear end all contribute to lower fuel mileage! Even when the vehicle is "warmed-up"! There were times I had as low as 12-13 when the temps dropped to -13 and -20* in northern NH(4x4 too) Now that I moved to a so called warmer climate: mileage ranges from 16-18 mpg on flat ground-where in warmer situations 24 is easily attainable! Fully normal in your location in Ontario!Just to rub it in...I attained 27MPG running east across Kansas in Nov with a hard tail wind on I-70!Awesome!

sounds about right to me..
i avg 14 city and used to be 20 highway prior to mods, now its 17-18 on highway.
drafting a semi will get ya 24mpg

Well my calculations were based on highway driving so I'm guessing I'm actually below the average but as of today I'm having some major fuel system issues I filled my tank up today and had the pleasure of watching the fuel poor out on the ground so I dropped the tank and could not find the problem the gas was coming down in front of the rear driverside tire the tank is brand new the fuel pump seal is not leaking and the valve on the front of the tank is working properly aswell my only guess is the evap canister maybe but my older brother decided to plug the valve on the from of the tank and bypass the evap canister entirely Is that a bad idea? Why? And any idea where I can find a fuel system diagram
