What is your average MPG?

What is your car computer telling you your average MPG is?

Mine is reporting 18.9 mpg (12.5 l/km). 2006 V6, manual transmission.

I have been monitoring the metric reading since the summer it climbed from 11.9 to 12.5 l/km. Anything I should suspect?

27-30 Mpg. Depends on speed, if I am going at an even 100 (60mph) then the mpg is roughly 29.5 to 30.0. If I step on it then the MPG factor goes down slightly. V6 automatic transmission.

22.5 miles per imperial gallon. That's over the first 14,000 km.

I keep all my information logged on a spreadsheet, so it's accurate. V6, 5 speed.

Best tank was 31.5 (all highway). Worst was 18 (mostly city, after I got the Magnaflow )

I average 26.86 per imperial gal. I only have 4600 KM on my 2008 GT/CS. The mileage is made up of approx 80% highway and 20 % city. I usually drive 110-120 Km per hour. Not bad for a V8.

When I check my gas mileage I usually do it the old fashion way with pen & paper. I checked it Sunday and I get 20.9 mpg in the city. Now if I go by the instrument panel, it says I get the same with an average of 25 mpg. I'm assuming that last figure is for the average of all tank fulls.

I drive a 5 speed manual.

Is that city or highway mileage?

Combination of both. My commute is 50 miles/day, round trip, on which my avg. speed is 34pmph. Top speed is no more than 60mph, and for a short time, so MOST of that is city driving. Not stop & go traffic, but hitting lights on various back-roads with low speed limits. (all of which I exceed a bit....of course)

Needless to say, I am VERY pleased with my GT's mileage. It looks like the there would not have been much of a gain to get the V6, which I did contemplate. Also: I do NOT totally baby the car. Actually I take the revs higher than most probably do, and I get on it almost daily. Note: I did see an improvement in the mileage with the addition of the CAI.

autotrans with 33'000 miles, 255 tires, using 91 octane US (95 eurosuper) because in Switzerland we don't have regular gas...

Actual average 21.4 mpg (11 l / 100 km): 70% highway 30% city, average speed 50 mph
27 mpg with 75-80 mph on highway
between 18 and 19 mpg when only city driving

'08 GT 5-speed with 1,500 miles. Bassanni long headers, X-pipe, Cat-backs, C&L CAI, Diablo 93 octane tune.

20.7 mpg

Truely mixed around-town driving. 10 mi of interstate here & there. Plenty of short blasts. Plenty of stop light racing. Plenty of short 5th gear runs.

I am very happy with those numbers.....

I get about 18-22 in the city and I am very happy with that. I had a 96 gt and it was horribly on gas!
