    My Gsi, under max acceleration 7mpg!!!

    Been doing some tests on my gsi this week. Been driving very calmy not booting and im getting 40mpg. Which i think i very good. So i though i'd c what it did when i floored it and kept it floored from 30 right up to..? dropped and levelled off at 7mpg. That explains why when i boot it even if not for long, i can watch the petrol gauge move faster than the rev counter lol.

    Wonder what a standard GSi will drop to, has anybody tired it. Also can any1 better 40mpg?

    Standard, mine will drop to around 9mpg, maybe worse.

    Best MPG I have had on a mixed journey is 34.5mpg - on average I will do 28mpg though.

    To be honest, that's pretty much exactly the same as my old SRi Tubo would get - although I could never get anywhere near 40 on an 'economy run'

    Its quite interesting but ive found that when running cold for first 5mins it runs in early 20s. When warm it gets late 20, early 30s and when pulling away its getting between 10-15mpg up to about 25mph. Over that it gets better. Best is around 50mph in 5th gear. Also you get better mpg @ 30mph in 4th gear than in 5th. I wouldnt have thought that. All in all im getting a better understanding on how best to drive it to maximise efficiency, as im putting in at leat £50 a week at present. Too much. I therefore must slow down, hence the tests lol.
