None, because I don't have time to drive it.

Averaged about 20 plus with full a/c and speed (80 plus) on the trip to Wichita and back in the GT... Have seen 24 out of the old 87S4 on trips down to Devek days (again 70 to 80 mph..seems to be a sweet spot).

Mine gets 12 to 13 mpg up and down the 405 here in Los Angeles. I get 20 to 24 on a run with light traffic at legal freeway speeds

About 11 mpg. Same as the window sticker says. All city driving. On the rare occasion I go any highway miles it seems to use a lot less gas. Best guess is @15.

VT928

Took a trip from Burlington VT to Watkins Glen NY for some R and R and a little wine Tasting/Buying, total miles 806. Average miles per gallon 19.82 for the trip. The trip across the southern Addirondacks on Route 8 is perfect 928 road, big sweeping curves and lots of tight twisty bits to keep it interesting. With a bonus of almost no traffic to speak of in the early am. Lets just say I enjoyed the drive and leave it a that. The last hundred miles from Utica on is a boring 75 mph down the Thruway to the Seneca Lake. 19+ mpg is pretty good for a 1980 Euro S that runs a 255/285 front rear tire combo, is full of luggage and several cases of wine, with a driver that is enjoying himself. The CIS injection was tuned by Kemp and delivers 14/15 mpg in town. By the way the exhaust on my car is very open.

On a recent 1200 mile trip I got 24 MPG out of my GTS. The best that I've ever recorded. Speed was 75 MPH and the car is modified with a US 2.2 ring and pinion of an S4 otherwise completely stock.

Our GT gets around 20-21 on the freeway @ 75 or so. We try to avoid that, as much as possible.

According to the digital dash "Durchschnitt Verbrauch" I am averaging 24 MPG with city DD - but our gallons are bigger than yours.

Only thing non-stock is the EIS.

My '88 5 speed got ~25 mpg at about 80 MPH on my cross-country (MD to CA) drive, not counting the mountains

Put on a supercharger, turbo, or make it into a stroker and your car and around town you will get single digits. Burnouts are just way too fun!

My turbocharged 928: 17mpg city, 26mpg highway @ 75mph; 30# injectors but used wideband to set cruise A/F to about 15.3:1.
