MPG question

[BLOCKHEAD1]

Hi

I have a 2017 Focus ST line automatic and I have a question about mpg. (apart from it being absolutely awful and way worse than my previous car which was a 1.8 Honda Civic Type S) 

The readout hasn't changed at all since I picked the car up. It hasn't gone up or down at all and is constantly showing 30.1 mpg. 

That can't be right can it?

It is likely showing average mpg which will take a while to change.

The best way to check you mpg is to fill the tank note the mileage drive about till the tank is at least half empty fill up,again then do some maths.

Although the brim method is best, you'll get a more accurate average by resetting it for your own ownership.  Press and hold the OK button to reset it.

Nitpick I know but I wish it was easier to reset the individual odometer in the mk8, I have to go to the info screen that shows mpg etc, press the option button on the steering wheel, then chose reset individual view, choose the trip odometer, then press and hold for a fee seconds.

on the mk7 it was one button, press and hold to reset.

unless I’m missing a quicker method?
