Gas Mileage Question
Hi everyone,
What range of gas mileage do you get with your 944 in the city? Or on the freeway/highway?
Thanks in advance.

About 22-24mpg overall and about 27+ on the highway if max speed is about 65MPH. If above 70MPH it doesn't matter...
Tire air pressure is important.
You can increase your mileage by professionally cleaning the injectors---www.witchhunter.com.
Cleaning injectors is one of the cheapest ways to improve/return the cars performance.
Do not waste your time and go to a garage that will "Clean the Injectors" on the car. It is a waste of money. You can do this for a couple of cans of good cleaner for the same results----usually none.
Old injectors are probably 6-18% or more below new/cleaned injector performance if origninal.

+1 on clean injectors, keep tires inflated, and keep your foot light and you will get good mileage. swap in a turbo gearbox and they get better.
highway MPG on a 944 seems fairly independent of cruising speed in my experience. i once drove from san diego to santa cruz, with the ac on in the middle of the summer, and got 29mpg average on "open highway"

I usually get about 17mpg around the city in my S2. I've had the injectors done, replaced the O2 sensor, new air filter, new plugs, new cap and rotor -- still the same. Stock chip AFAIK. I've just stopped worrying about it for now.

My 1983, 944 5 speed DD is easily returning 22.5+ mpg cross city commute. The Syracuse area I commute in is not real bumper to bumper, stop & sit, but still many stop lights and no place in my commute is speed limit over 45 either, hardly ever in 5th gear it seems.
On my trips I got darned near 30 highway, with the high 5th gear used. The full tank range is 350+ per tank for me and seldom do I see the yellow low light, and that is almost 2.5-3 weeks between fillups. So I seldom get a real check of long highway tank use...Oh and I do not flog it.
