How accurate is your MPG monitor?

average fuel consumption since the last reset.Resetting is done by pushing the switch*B
for longer than 1 second. (The average speed is
also reset at the same time.)

The display is updated every 30 seconds. At
about the first 1/3 mile (500 m) after a reset, the
display shows “——”.

So, it is just an "average" based on the last 30 seconds or so of driving. Mine has been awfully close to the actual computations when filling up. Of course, I round off to the next increment ($$) so I probably don't get an exact read on gallons I put in.

the display is updated every 30 seconds, the average is from the last time the driver pressed reset. If you reset it and drive you will notice drastic changes in mpg at first in relation to acceleration and deceleration or idling. After driving for a while it starts to average out and changes very little.

OP, track your miles and fill ups and reset the mpg at each fill up. I get 21 - 22 mpg and I have a heavy right foot, and twitchy left hand on the paddle.
