[Arragonis]

COCyclist - I'm pretty much doing what you do (I think if I understand it correctly) but I'm getting nowhere near the figures you are. OK my engine has more hp but the Fabia is lighter than the Golf and I have the 6sp.

I think I'm hitting a plateau and I think (maybe wishfully) that it is the environment. In terms of time the first 1/2 of my journey is queuing traffic. I engine off when I can but its sometimes crawling so not much chance to (loads of beeping because I choose not to sniff the behind of the person in front of me all the time).

Then the second half is 4-lane (2 each side) bypass and I sit on the left (slow) side with the trucks sometimes, although I sometimes go on the right. The difference between a 'good' and a 'fast' run is maybe 45 vs 50 average MPG on the computer. The journey back is in reverse and I can carry up to 65 before the traffic starts and then if I get a good run maybe 55 by the time I get home.

But my tank to tank average is only just nudging 50-51 Imp.
