Zero10

I just finished a long road trip, and I was absolutely shocked at the mileage I got, so I thought I would let everybody on here know. I drove 1040km's (650 miles) on a single tank, and it was still nowhere near the 'R'. Took only 60 litres!! That's almost 41mpg (us gallons) or almost 51mpg (british gallons). I never thought this car would get such good mileage. For us canadians, that's 5.77L/100km's. That rivals the new VW TDI's.

I remember when I bought this car, I was lucky to get 400km's to the tank.

Anyways, sorry for wasting forum space with shameless bragging =)

What kind of roads and at what speeds. Any traffic slow downs? All flat roads or hills?

slowazzporsche

yes i'd be interested in this too, i can go roughly 700 km on flat roads with no stops about a constant 140 kph (90 mph) on a full tank of premium and then i need to re-fuel

Zero10

I kept it right at the speed limit (110kph), except when it rained, spent about 1 hour at 80kph in 4th gear, I'm sure that hurt the mileage a bit. (yeah right!!). It was about 50% hills, 50% flat, but no really big hills, only a hundred or two hundred feet high. Had a reasonable head wind for part of the trip, maybe 40kph. My tires were all about 15% underinflated (whoops!). The traffic was reasonable, quite a few cars, but they were all moving pretty good.

This car never ceases to amaze me. The whole trip I was waiting for the needle to fall to the R, and the light to come on, I didn't believe it until I got back to Calgary, and filled it up (because I didn't believe I still had 1/4 tank left).

Lol, 140kph, that'll hurt the mileage.
Remember, wind resistance is proportional to velocity squared. So, the force you are fighting goes up with the square of your speed. Makes a big difference between 110 and 140.

Just out of curiousity, do you see a mileage gain with the premium? I used to run premium, since it gave me a few more kilometers to the tank, but I worked it out, and I just don't gain enough to save money by running premium. I don't really feel the power difference either.

Oh, one more question, when they publish mpg in a magazine (like car & driver), do they use british or american gallons? Their numbers always seem too good to be true, unless, of course, they are using british gallons.

with premium all i see is that the car smells prettier when it runs so rich haha, you can use 87 in em sure but i'm used to throwin 91 in it, just a habit, it.. well it FEELS to run smoother between reg and premium but mid-grade seems to do the same, i figure what's the extra $2.00 between the two :P

they use american gallons to the best of my knowledge.. whichever one it is that's roughly 3.78 cdn litres

I noticed that my gas mileage got better as I piled the miles on my n/a. Does that make any sense or was I just trying to see some advantage to having a car with 250K+ miles on it?

Dave951M

Michellle, it does make some sense that the older car can get better mileage, assuming that the rest of the car is well maintained. What happens is that as the mechanical systems of the car are used, they naturally "wear in" the tolerances to optimum, meaning "looser", resulting in better fuel economy. So, your observation doesn't seem out of line from what I've observed in other makes. I wonder if anyone else has been watching their cars like this as they age.

I've always noticed that these cars getter a lot better mileage than one would ever expect... that is if you can keep your foot from pushing to the floor board every 5 seconds :-)

I have taken three 1000 mile road trips this summer....typically at average speeds above 70 mph - and we pull down 29 mpg +/- on nearly every tank - the hot day of stop and go through DC on I-95 was the exception 24 mpg

I get about 18 mpg is that too low?

Mike1982

18 really depends on the kind of driving. I know when I drive around town and hard, I guess I get about 15 or 16, but when I am like normal in town I pull in 19-20. On the highway I pull in about 24-25 but that is also because my car just LOVES 80 mph, so I know that has to do with it.

I have checked my mileage on the last couple of fill-ups. I am averaging about 23-24 mpg in my daily driving. It is not city traffic and it is definitely not highway driving. And when I get a chance to stand on the gas.... I do. If I really wanted to go for high numbers, I think I could get 30 mpg without too much trouble. Where's the fun in that?

Anyway - it's nice to have an economy car that handles this well and looks so sharp.

slowazzporsche

my 911 got about 20 mpg in the city with some "spirited" driving, not much "heavy" traffic up here.. our gridlock is from about 4:45-4:46 haha

jeeper31

I am getting 18 on the high end. this is not my daily driver so when I take it out it is usually for some fun. My driving is mixed up between local and highway. I would thinnk with the amount of highway I do it would improve the mileage a little. Thinking about changing the O2 sensor. I hear that is supposed to help.

I tell you....this car has alot of wonderful things going for it. Looks, timeless design, all-aluminum engine(unheard of in 1983!), supercar roadholding, and good top speed....are all standard features of this car. If Porsche were to re-introduce the 944 family all over again- it would undoubtedly become the fastest-selling car of all time. I still don't know of any car freely giving its' owner the overwhelming value of money well-spent today. Porsche will never be in the position it was in- when the 944 was introduced. And, I dont think they will ever be able to create another car to top the 944 along the same appearance/performance/value category again. Consider ourselves the remaining few- who can really make or break this cars' bright future, as a sought-after collectible piece....or simply a rusting, neglected poster child for another "Abandoned Autos" scrapbook.
