    Driving style can be on the fast accelerating at times but i'm a smart driver so i also know how too save fuel at times when needed. 99% Local driving very rare too hit the highways.

    Tank size is anyone's guess as it's not standard and has a large dent, But takes on 66 litres average.
    14.6l/100km. 19.2/mpg. It could and should run under 10l/100km 28/mpg 100% on the highway.
    Had to quote myself I done a better one..

    Over the long weekend of TGWE2.. And beyond 80% Local 20% highway

    I used 77 litres of 98 octane fuel.. For a return of
    670km.
    11.4l/100km
    24.5mpg.
    I had a touch left but my best estimate is between 2-6 litres in ore out.

    I we went 40% highway it would just get better and better with more highway travling. I was pretty happy 3 big guys in the car.

    Pleasantly surprised.

    140 miles on Sunday on "Rallye in the Park" as course opening car and assistant clerk of the course.

    Blasting it on twisties and flat out on stages/tests.

    Managed 18mpg !!! Expected to be MUCH lower than that given I was revving the t!ts off it

    Last tank yielded 13.04mpg, or 18.03 l/100km. Believe it or not, this is the best tank I've pulled doing my normal in-town commute.

    Took a spring break trip to Louisiana last week, girlfriend's car got 28.42mpg or 8.27l/100km. I thought that was very good since it's only rated 27mpg highway and we did in-town driving as well...

    Toady on a 110km (95% motorway, 5% city) trip I've managed 7,1l/100km (39.8mpg) by driving on the legal speed limit. Not bad for a supercharged hot hatch.

    I've heard figures of around 1l/1km... I don't know if they are correct though. My personal best is still 1l : 20.5 km's

    Fuel economy has made a stunning comeback lately.

    Before the start of April, I was averaging about 26mpg, sometimes 28, sometimes 23.

    However, my last part-tankful (60%) earned me a cool 270 miles- which is exceptional. That means I should have been able to get 450 miles from one tank, which would be about 41mpg. I'm on track for 320 miles from this tank (80%), which is just about 37mpg. Not bad at all, seeing as I've been doing some more... 'spirited' driving lately.

    2001 GMC Sierra, 5.3L V8, Supercharged. 95% city 5% highway. I typically use about 50% throttle depression for normal driving. I average 4-5MPG.

    I'm surprised it's that low. Superchargers don't use that much if any extra fuel unless you really get on it and spool up some boost. Does "50% throttle depression" do that in a Sierra? And are these separate Sierras...?

    I'm averaging 25.73mpg or 9.14l/100km in my Focus, including the 118.1 mile highway trip home from buying the car. So far I've put about another 400 miles on it on rolling-hilled country roads and in-town driving. This tank's shaping up to be lower, though, thanks to a heavy right foot!

    Highway mileage is very good though. I used cruise set at 65-70mph with some a/c usage, and got 31.61mpg or 7.44l/100km. Lowest was my first tank in town before I'd learned to drive it economy style; I got 21.22mpg or 11.08l/100km.

    No that's my Sierra if I had $3,000 lying around and my real Sierra.
