Are these figures taken from the computer or from working it out manually by calculating it from miles covered by a fuel tank?
Also, how does the computer calculate MPG? Is it just tell you what the car is doing at that moment? Or if you continue at those revs? Or does it average it over the whole tank??
Taken from the computer. Their pretty accurate on my 182.
When you hit the reset button, it takes a few hundred meters to pick up a reading. When it does its basically what your doing then and there, but after time it starts to get the average since its been reset. If you see what i mean. I was wondering why the fuel was going down so quike, checked the mpg and it said 31.5 !! Bit low for a 1.2 lol. Its soooooo slow.
