I live in a rural area and the trip computer on my 12 year old S40 consistently shows fuel consumption between 36.0 MPG to 36.6 MPG.
Lower figure is for short journeys and the higher figure relates to longer journeys in excess of 100 miles. I use these figures for budget purposes and found them to be accurate. |

Mine has always been pretty accurate, and it's the older digital readout with the virtual fuel gauge and the bars. I commute an hour each way every day on rural and main roads, and currently get a consistent 37mpg with a mixture of aircon use.
As has been stated though, it is KEY that you reset the average fuel consumption counter every now and again. Ideally at each fill up. Otherwise it just eventually seems to stick. Quote:

AAND, avoiding the risk of starting an MPG war and hijacking the thread, this actually happened once after a 300 mile trip. And it was correct(ish). Not bad for a 1.8 Volvo engine.

Just wondering where you can drive 300 miles all downhill
My favorite is hitting the highway with a full tank on Friday night after a week of commuting... the miles to empty keeps going up for the first hour |

Mine usually shows about 3mpg worse than it really is, on a long run a few weeks ago the trip said 33 but when I filled up again and did the sums it equated to around 37, and that's with the engine light on for half the time (although it's now gone off again on its own 🤷*♂️) so obviously O2 sensor errors don't screw the mpg up.
