Hi. I seem to filling up on diesel too often so installed an OBDLink LX to check fuel economy and it's reading 8-10 mpg after driving around town all day!
Is this accurate or have I set it up wrong?
Im assuming 80l tank, 2000kg kerb weight. Not sure how to estimate current fuel % What other variables might I have forgot to input?
It's a Mk7 LWB, 2011, 55k.
