Since may I have started recording my consumption in an exell-file.(driven 1403km since then= 871,78miles
My total average is: 5,0809 liters/100km= 1/19,68
US gallon: mpg=46,2888
Imperial gallon: mpg=55,5955
The lowest I got since then with one full tank is: 4,8120liters/100km
US gallon: mpg=48,8755
Imperial gallon: mpg=58,7022
I have a very gentle hand.

(women like that) And I check tire pressure once a week with a digital meter from michelin.
I actually once got 4,6 liter/100km but that wasn't accuratly calculated. But I will get those figures in the future again, that's for sure.
My bike is again full stock(since recording consumption), I had the leovince system before and it actually had a lower consumption because of the absence of a cat.
