    Has anyone tested fuel octanes vs. mpg in a scientific sort of way WITH THE 1.8Ts specifically over different lifespan of the car in the stock config? I just averaged 28 mpg using 87 octane with total highway driving at 70 mph avg. I have my doubts 91 octane would improve on that but am going to try. That's with tires at 32 psi cold and brand new air filter and OAT of 30 degrees F.

    Up until lately i was averaging 31mpg but recently im around the 28mpg mile, thats since using v-power, ive started changing gears a few 100 rpm higher up now and its made a difference to mpg, cant believe it.

    I thought I recognised the username! If you're anywhere near the northwest and want a run in a mapped S3 let me know, i'll trade you for a run out in your 205

    Back on topic, my mpg has noticeably improved since I had it mapped to run VPower, the fuel costs more but it evens itself out. I also don't drive the car hard very often and when i'm on the motoryway i generally use cruise control which helps get optimum mpg. Despite all this, if economy is high on your list of priorities I'd avoid a fat, turbo charged, 4wd petrol engined S3!

I do mainly town driving and generally see about 150 - 160 miles off 20 of VPower, and thats mapped. The most I have achieved off a full tank is about 450 miles, the majority being motorway miles.

    P.s. Do you go on 205gtidrivers.com? The username seems familiar and I notice you have Pug...

    i do about 75% motorway miles in my leon fr tdi and get 500miles to the tank. if i could get your figure in an s3 on my drive home, i would be happy.

    I filled my tank up a while ago and drove as carefully as possible and tried not to be tempted to put my foot down at all (but failed once ) to see what mpg I could get. Got about 400miles which works out to be 33mpg which I thought was pretty good especially when I didn't do any motorway driving.

    Cruise control actually uses more fuel than if you used your right foot as no matter what incline you're on it keeps you at your set speed. Where as doing it yourself you can judge where the inclines are and adjust your foot accordingly, i.e. gain momentum down hill to roll up the oncoming hill or just keep your foot resting on the throttle and don't move it if you're going up a hill even if you slow down a bit then lift off when going down.
    Next time you use your cruise control you should watch your constant mpg thing on the lcd computer to see how far it goes down compared to using light throttle with your foot.

    I do, and cruise control seems to get better mpg, hence why I use it? Oh, and also because i'm lazy

    The whole 'rolling down the hill and creeping up the other side' thing is just a bit anal in my opinion, if I was that bothered about mpg i'd buy a diesel.

    The S3 might be quicker of the line but at speed they will be similar due to the high torque produced by the bmw. Parkers show it as 7.6 or 7.4 which aint that slow either.
