Good to know the long term ave is 29.9 I guess

I reset mine at every fill up too - helps me know when I've been a little too heavy on the gas + it's a good check everything is working as it should (increasing fuel consumption could indicate a problem/need for a service for e.g.)

I see between 9L and 12L/100km or 19-26mpg depending on how I drive.
I've noticed that I see between 12-15L per 100km or down to 15mpg when I am on higher ethanol fuel (e50-e85)... but that's also when I tend to drive a little faster.

Best mileage (highway driving, constant speed) is around 6-7L per 100km or 33-39mpg on normal fuel. On ethanol it actually drops a little and the BEST I've seen was around 5.5L per 100km (42mpg).

Interestingly I have also had some bad mileage since fitting a full exhaust... cos you know... you need to hear it a bit more often
