Lying Cars (Dash vs Reality)
Discussion
My company car claims on the dashboard that it is averaging around 55mpg, and has said approximately this since I got it earlier in the year.
I thought though it would be good to just check what it actually is doing to see its accuracy. I presumed a slight variance may happen of a couple mpg. Reality is the car averages betweeen 46 and 47 mpg. That's a difference of over 10%! I guess I was naive to think that the car would be able to produce a genuine figure? Are lots of manufacturers playing this game as well, fooling their buyers into thinking the car is doing better than it really is?

I suspect they are almost always overoptimistic. My old BMW used to have a correction factor you could type in to make it accurate.I thought though it would be good to just check what it actually is doing to see its accuracy.

Are you going off a long term average?
My Golf lets me do "journey" "since refuel" and "long term" and I'm one of those sad gits who brims it, zeros the counter, then goes home and plumbs it all into a spreadsheet and it's almost always within 1-2mpg.
Spreadsheets? How 1996. You need an app, if for no other reason than to annoy the person behind you by taking even longer to reset and record everything My Golf lets me do "journey" "since refuel" and "long term" and I'm one of those sad gits who brims it, zeros the counter, then goes home and plumbs it all into a spreadsheet and it's almost always within 1-2mpg.

I work in IT and honestly, there are times when I see things and simply think "why?" and apps like Fuelly are one of those times.I don't get the benefit tbh, assuming a single car and I just want to know my MPG and what it's cost me.

When you say you work in IT... Are you an Oracle dbadmin who sits in a cupboard all day?
