Experts, is the fuel consumption display accurate? [facepalm]

Don't worry too much about the accuracy of the displayed fuel consumption. Just keep track of how many times you refuel each month and how much you spend. After a few months, you'll know if it's accurate.

It's inaccurate, always shows a bit over 6, but when I actually drive, it's around 7.

Why care so much about fuel consumption? Just refuel when you're out. It's that simple. For typical city driving, it's usually around 7-8 liters, and on the highway, it's around 6 liters.
