I get between 5 - 8 MPG. I really only drive it on the track.

 

^^^ This is closest to what I get. Since replacing my coils, I'm getting an average of almost 23mpg between around town & highway driving. This is a FSI Stage II 3.8L w/ IPD plenum and GT3 Throttle body. When my coils went bad I was still showing around 17 or 18 mpg but the car just ran horribly when it was warm (ran fine til it warmed up)... I can't say it lives above 3500 rpm though (more like 2600 - 3k with a few runs up to 4500 - 5k).

 

Rarely rev the engine over 4k rpm? You guys are crazy, I've owned 911's since 1992 continuously and can say except for first gear I never shifted under 4k. 2 of them were 996's with original imsb and never had a problem with either of them other than batteries and an alternator on one.
I think you're asking for trouble running the engine its whole life like that. I didnt beat the hell out of em but I drive em like they're supposed to be driven and I've never been let down.

 

My weekend loop is around 100 miles and I know I need to add about 8 gallons for that, sooo...around 12.5 mpg.

If you're getting more, you're probably doing wrong.

amen

 

Yep, pretty much! My rib-jab is always "Are you buying it for the gas mileage?"

Foot down, keep the left foot and right hand busy, smile, then fill 'er up!

 

Gas mileage actually does matter, even if you are super rich.

I used to have a V10 M5, and my friend has a Shelby Mustang. Each are around 13mpg, which limits range and enjoyment when you have to stop every 220 miles for gas, especially when you want to get lost in the country and don’t always know when and where the next gas station is located. It can deflate the fun and add anxiety to an otherwise relaxing drive.

Plus, it’s cool these old cars made in a previous century are getting the same mileage as my wife’s 2019 BMW X3.

 

I figured the German engineers put the 4k on the tach dead center because it was the manufacturer’s suggested rpm, lol.

 

Admittedly I drive my '03 C2 in a fairly mild manner, but on country roads (speed limit 45-55, stop every couple miles), I get about 24. Cruising on interstate in 6th gear, I get 28.

I have no idea what the number would be in city, stop-n-go traffic.

 

I get around 20 mpg combined, and I rev it to 6-7k whenever I get the chance. Although it perhaps doesn't really matter how much the gas costs, I think it's still good to keep an eye on your mileage as an indicator of any problems.

 

Dporto,

Two quick questions for you.

1. Since you have an FSI engine, how do you handle servicing it? Has FSI designated a shop that can handle it or do you take it to your preferred shop.

2. Why don't you run it above 4500-5000 rpm very much?

​​​​

 

In my case, some of us just like to cruise. I'm not out to win any races, just love the driving experience as a whole. Sure, will punch it from time to time getting on the highway or down back roads, but most places I'm going I just want to hear the beautiful notes coming from the rear end.

 

I've gotten as high as 26mpg on highway not going 55. There were periods of straight 80mph cruising. Around town I'm getting 18-19mpg.

 

I have 2 FSI engines, Change the oil, keep the hood shut and drive.

 

Itusler,

​​​​​​What would you do or have been instructed to do if you need to service the car beyond an oil change? Ship it to FSI?
