When going across country this past summer to Grand Rapids, MI and back, I set cruise to 95mph most of the way, and I got 23.5mpg.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

What's the best mileage any of you have ever achieved in a 996 C2? I decided to try one day, and drove like grandma would: 31.4 mpg at freeway speed. I was surprised. Normal city traffic I get closer to 19 - 21 mpg. Coincidentally, these are also the thirst 3 digits of pi.

POST 3Original post

Never drive that slow again...have some self-respect. There is an image to uphold here. I just drove from Daytona to Jacksonville with a pack of BMWs. Average speed was 95 and the Avg MPG was 26.

POST 4Original post

The only time I pay attention to gas or MPG is when it's time to get more. There are certain things I simply don't pay attention to in the Porsche, and fuel consumption is one of them.

POST 5Original post

My trip from San Diego to Vegas and back last night got me 23.1mpg. I had cruise control set anywhere from 88-95mph on the way there for traffic, and 100mph on the way back. When going across country this past summer to Grand Rapids, MI and back, I set cruise to 95mph most of the way, and I got 23.5mpg. At 90mph, I get right around 25mpg.

POST 6Original post

75mph....26mpg on the East Coast (pretty hilly). Amazing cars....amazing. JB

POST 7Original post

If you drive that slow twice in one year, you are GUARANTEED to have a RMS leak! Read the fine print in your manual.

POST 8Original post

well when I fill up, I average 17 mpg eventhought the comp say 24-25

POST 9Original post

I got a flat tire about 100 miles outside of my home. Had to put on the donut and drive all the way back at 55MPH. I averaged 30.9 MPG. Simply amazing that these are 30MPG cars.

POST 10Original post

Well I got 99.9 downhill. Try it, find a really big hill and coast down

POST 11Original post

25 mpg over 1000 mile round trip to and from AZ - with a suitable amount of right pedal abuse

POST 13Original post

how do you get the display to read out mpg? i could dim the dash, set the tme, reset the trip and swtch between miles and km but how do you get to the mpg setting? also when i turn on my car the ac turns on with he car, how do i turn that off? sorry for all the noob questions....

POST 15Original post

Try filling your tank and then zero out your odometer. Drive until your low gas light comes on then fill up and divide miles by # of gallons. That should be the accurate way to determine mileage. I don't rely on the computer to determine gas mileage.

POST 16Original post

Quotes source post: 3866672

MPG = Miles Per Grin. The faster you go, the more Miles Per Grin!

POST 17Original post

2003 stock C4S 21 MPG (mostly HW) 1500 MPQ (miles per qt Mobile 1)

POST 18Original post

The mileage on these cars seem very sensitive to how you drive 'em - much more so than other cars I've owned. I've gotten as high as 26 (mostly highway), and as low as 14 (around town) on a tank of gas. Of course other factors come into play but it seems like if you're light on the throttle you'll get decent mileage, especially on the highway. - Nick

POST 19Original post

One afternoon, drove from Seattle to Anacortes, Wa -- about 75 miles freeway driving. Got 30mpg on the way to Anacortes & 29mpg on the way back. Confirmed through checking the numbers. I very much like having a degree of control over my fuel mileage. It doesn't bother me at all when I get less, but have more fun. But it's nice to be able to float along on cruise if I want and get really quite respectable mpg. It implies to me that the fuel injection is really dialed in--only giving the engine what it needs for the conditions.

POST 21Original post

never get more than 15MPG....but then who cares?? Get a prius and you get 40MPG

POST 22Original post

After changing 3 of the 6 plugs (I know, I'm slack), I drove 230 miles in the Interstate and averaged 26 mpg. That's my best ever and I was averaging 80 mph. Still have to order/replace at least 1 spark plug boot and the other 3 plugs that are going to be BEARS! I was amazed to see the 26 mpg. Best before that was 24 mpg on the same route a few months back.
