Average MPG - Longterm - GTI

[GolfTi]

11 gallons x 37mpg should be over 400 per tank.

Mine after 17k is 36mpg long term. I normally get 370 or so before the refuel warning. 400 in total if I'm lucky.

Are you remapped? Indicated fuel consumption becomes a little optimistic if you are.

Momentum seems to give another 20-30 the odd time I've tried it.

3,300 miles in, and showing roughly 33mpg on the long term still. This isn't helped by my wife doing too many short journeys for my liking.

What is the rule on the long term MPG resetting? Mine reset recently (maybe around the 3,000 mark). Does it reset itself at set intervals?
