What I notice more than anything else is the way the fuel gauge plumets. Even tho' it does about 32mpg, the tank is tiny, so I can start the week with 3/4 of a tank, do 200miles and it's on the red.
Small tank = less fuel..... less fuel = less weight.... less weight = better mpg....
This is the thinking behind the smaller tanks....

Update, switched the lights to long seems to have made a difference and I have noticed they now go on/off based on the sun/daylight etc.
