It even has tire size correction, so you can get more accurate mpg based on real distances and not based on numbers written on a car dashboard.
Or good old brim to brim, divide miles driven by fuel added, repeat a few times for accurate figures.

I have a spreadsheet dating back to 2005, no need for these apps!
Yup, I stil have good old Excel as a backup ;)
Yes, I back up to Excel too. Have data for my last 5 cars across almost 20yrs. Best mpg I ever recorded was in a BMW 320d manual on a trip from Calais to Cahors in France, almost entirely on French motorways. Myself and 1 passenger plus boot and back seats full of luggage. I got 78.6 mpg measured brim to brim!

How do you manage brim to brim with the XC40's double flap filler? Surely you don't go off the auto pump click off?

Like any other car Walter. I never go by the first click off, carry on until the trigger won't dispense any more.

Then it very much depends on the individual pump. For me brim to brim literally means that you see the actual surface level of fuel in the filler. Anything else and you're guessing.

This is why I use Fuelly.
Nothing complicated, accessible as a website or an app.
It can give loads more data if you want or need it but I have used this for years

It worked out at 34 mpg in the morning and 33.6 in the evening. It's not just that Volvo On Call told me these values, but I refilled the same amount of diesel fuel at the gas station near my home.
I'm not that satisfied with 34 mpg for a D4 engine, but I blame the Pirelli Scorpion Winter tires on that. Hope I'll get better results with Continental summer tires soon.
With such a high average speed (120-130 km/h) I’m not surprised by your fuel consumptions. Due to lower aerodynamics of the car, driving above 100 km/h tends to punish mileage much more compared to a sedan. My T4 FWD driven at 130km/h (80 mph) returns 8,2 l/100 (34,5 mpg), whereas at 100 km/h returns 5,8l/100km (48,7 mpg).

Unfortunately, summer tires won’t decrease significantly consumption figures, but higher outside temperature will surely make a difference...
Hi eugen61, I just found out this interesting video on XC40 D4 AWD consumption
It pretty much sums up and confirms what we were talking about :)
