No matter how I ride I always seem to get roughly 200 miles to a tank (20l), which is about 45mpg 55 mpg.


Most folk seem to get about 10mpg more so I'd like to know what I'm doing wrong!

FTFY when you do 200 miles per 17L (because you never spend all 20L) is exactly 55 mpg.

You are fine

Oh that's good news then, so what I was doing wrong was the maths, not my riding.
