What MPG do you get in your 951?
 

I average about 20mpg in the city driving like a grandma (gas is $4/gallon here for 93), running consistently on a 10-gallon refill to keep the car light. No spare tire or tools to weigh me down, but do have 285mm rear, 245mm front tires.

On the highway this last weekend, I did 600 miles @ 21mpg average, 65-70mph, lots of hills, full car (600lbs of people, gas, luggage, dogs)

In the city, with just me or me & the misses in the car, I average about 20 in granny-mode.

My car has rebuild injectors, 928 pump, Vitesse chips with an adjustable FPR running 30psi fuel pressure (no, I don't get on boost at all with it 8psi low)< but found a semi lean & clean 15.5:1 at cruise which is about as lean as I can go w/o feeling the reduction in fuel.

I ran 31psi down there for 20mpg, 30psi back for 22mpg, but it's bordering on way too lean & of course, I don't dare get on boost like that.

Just curious to see what others are getting.

I get 23 mixed highway/city 50/50 mix. Straight highway doing 80 MPH I got 28 MPG.

With the turbo mill in these cars you can get 28 mpg. That was just me and a passenger plus our bags oh and no A/C cause mine is broke.

Interesting. I tried 10 gallons a month ago with one gear higher: ie, always between 2700-3300rpm, both city & highway: my MPG dipped down to about 19. I was thinking that since engines are more efficient, maybe the efficiency over-rides the extra fuel needed to sustain the higher RPM, but appears to be invalid.

Normally, I'm low RPM & high vacuum.

On a California to New York trip, 25 mpg highway at 75 mph. Moderately loaded, no passenger.

Mileage on trips with city and highway average in the high 20's to 30 mpg. There is more info in this thread...http://forums.pelicanparts.com/porsche-944-turbo-turbo-s/590862-951-fuel-mileage.html

I did my first track day the other day. I went 70 miles and used pretty much the whole tank. It's probably in the 6-7mpg range. :) that's probably not the info you were looking for though

I've been getting mid 20's on the highway but it's been a long time since I've driven it long distance much less around town until this past week after it sat in the garage all winter.

~23MPG in mixed city driving.

On a trip to Road America a couple of years ago I managed 32MPG, once there and on the track..6MPG.

Generally 15 mpg city and 20 to 25 mpg highway but depends on how heavy my foot gets.

At times I can smell fuel, but is always fuel-vapor free under the hood & yes I've changed out my hoses. Wonder if I have a leak out back??? :(

I replaced the cam tower gasket recently, was getting just below 20mpg before, now I have
driven it only 90 mi. or so and used half a tank. This car is all orig. equipment except for boost enhancer that I have set per instructions from Lindsey.
Nothing seems to be wrong, no excess gas smell, runs well, new plugs, wires, cap, injectors sent to witchhunter for cleaning etc.
Guess I need to do a bit more poking around.

Do you have a wideband? 14.7 air:fuel at idle and cruise?

If the oxygen sensor is out of order, the system goes rich.

consistent 26mpg...

22-28 depending on how I drive it.

Well that and the weather.

0, ZIP, NADA, NO MPG.....Car is sitting until I get 2 more project cars out of my garage. Then I'll have the time and space to freshen mine up. Actually, was getting about 27 highway, about 20 city.

I get 30-31 driving about a steady 65 mph with car fairly heavily loaded and TP at 37 psi. The best I get in town driving is 23+. On the track it gets 6-7 mpg. I have a k27, 3 bar fuel pressure, MAF. Three years ago my O2 sensor went bad and the highway mileage dropped to about 25. With a new O2 sensor, it popped back up to 31 ish. Fuel injectors have be professionally serviced.

18 in the city. ..I definitely want to get more without driving like a snail. ..

My town driving is nothing like city driving. I don't think I'd get 23 in a 'real' city.

i just replaced my AFM with another Ohm'd good one: so we'll see how the next tank or to does.

The only way to get better fuel economy, is to run skinnier tires - but who wants to do that?
