I have a stock 92 Si4WS and get about 25 mpg in town and on the interstate with the cruise set at 80. I only get 330 miles on a tank. I do get 32 if i drive 60 on the highway but i don't do much highway driving, mostly interstate. I live in Montana and ny elevation in from 3000 to 6000 feet which I don't know if that makes any difference. Now that i think about it my car has never been to sea level. it looks like i'll have to take a road trip to the Washington coast to give it some low altitude driving

I was wondering how my mileage compares to what you guys are getting.

 

Sound about right. I have a 92 SI 4WS and average around 25mpg @ 250-1000Ft. I have AEM Cam Gears , AEM Intake with K&N, Full Apexi Exhaust, Noligy Plug wires with NGK plugs. I am sure I am missing a few things. But you get the idea. Now that im 31 I consider myself a sport driver. I don't race everything that pulls up next to me anymore. So my driving is mildly agressive most days for fun. average speed on open road is usually 65-75 cruising 1/2 - 3/4 throttle acel.
