I was curious what others get for gas mileage.

I am getting about 15 mpg on the highway with my '83S Euro 5sp. I wondered if that is about right. That is from a 200 mile trip at average speed of about 75 mph.

Am I in the ballpark with the rest of you?

Thanks for your responses.

I generally get 18-20 on the highway at around 80 mph. 15 around town.

 

Ditto, Mitch. 20 hwy/14ish town. But then I'm a lead foot.

Joe, you may be a bit rich but sure beats bein' lean. Bet it pulls pretty well.

 

Mitch and Mike,

Thanks for the info. Mitch, I'm assuming your car is US model. I wonder if the fact mine is EURO makes a difference?

I believe Mike is correct, my car must be a little rich.

Anyone else care to contribute mileage numbers for me? Thanks in advance.

Joe:

In mixed city/highway driving, I average almost 17mpg. On long highway trips, I manage to get over 20mpg. I never have a tank that's used only for city driving, so no figure for that.

 

Joe-

I know a guy with an 84(?) Euro S and I asked him what kind of milage he gets and he said almost always between 20 and 22 depending on his driving.

 

I've been getting really bad mileage lately with exclusively in-town driving. It was as bad as average 13.1 MPG at average 35 MPH on the last tank. Of course, that's including some rather sprited driving, too. <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" />

Odometer just turned over to 60000 yesterday and that means it's time for a new oxygen sensor. Maybe, just maybe, there's a relationship there. Isn't running rich (I'm pretty sure I am) one of the symptoms of an old oxygen sensor?

I just got the replacement oxygen sensor a few days ago, so I guess that's another job for this weekend.

 

I average 500 miles a week (irrespective of the vehicle I am driving that week). About 60% of that is highway, but heavy traffic with toll booths. I get an average of 17.5 MPG. This has been pretty constant for the last 10 years and 80,000 miles on "Gretch".

 

Uhh, mileage?
I just put $10 in every few days....
Must remember to fix thatlow-reading fuel gauge.

Ahh, forget it. I don't really want to know anyway.
Did Porsche even mention mileage when marketing these beasts originally?

 

Mine has a Fuel consumption gauge! Doesn't work though. In fact PO had it repaired 3 times by the porsche dealer. Maybe Porsche also thought, "Ahh who cares!"

 

My low fuel warning light typically illuminates with 6-7 gallons still left in the tank. I don't know or care if this is normal, since it's at least consistent.

When the guage reads as at or near empty (but before the light comes on), I usually get about 16 gallons in with a fill-up....usually about 280 miles from full.

 

I got 25 on the highway once. But it town i get maybe 10-12. I really do think i have lead in my foot with the new exhaust.

 

Not lucky enough to do any worthwhile Highway driving, but in city driving I get the equivalent of 18.5mpg (15.5US mpg).
Also, when red light comes on fill is 70Litres (about 18.5US gal.)
Note: car has no cats (factory) and runs on Premium unleaded (98 Octane....Factory setup is for Super (95 Octane))

 

I only do high way driveing. Houston being Houstion, you get on a high way to get anywhere. Plus I don't drive there much.

I just finished a 344 mile one way trip, I used about 16 gallons of gas. (Haven't filled up yet for the exact number) That works out to about 21-22 miles per gallon. Average speed, includeing stops, 59 mph. That was alought of troling through a small town at 30, and then accelerating to just under 80 before makeing it to the next town, and doing it again, there was a final finish way faster when I got to with in an hour of my house, as they're back roads, and I know them well.

15 highway sounds low to me, but maybe thats why the US got the L-jet fuel system.

 

16mpg cruising around the Bay Area; about 22mpg on long trips. Of the three 928s I've owned, this is clearly the most fuel efficient one.
