AVG MPG drops little by little at the Stop light

[scorpionKing]

Anyone notice that their AVG MPG display ticks down while at a stop light? Here is the scenario: reset the AVG MPG (to zero) on a nice long road (5 or so miles), notice the AVG MPG (anywhere around 27-30). come to a stop, foot on the break, and notice that the read out on the AVG MPG is ticking down. Usually by .3 - Asked dealer service - clueless, called Ford - clueless. I just want to know if this is normal, or is a glitch in the computer.

yea it is normal.do you not use fuel while sitting at a stop light?and are you also sitting still?so you are burning fuel and sitting still which means you arent making any miles per fuel consumption.also you have rest the mpg calculator and there for the numbers it is averaging against are not that may as it would be if you didnt reset.it does an instant average which means it take a reading every second or so.so say you are getting 16mpg while driving its constantly adding 16 and dividing to get your mean(average) of those numbers.now with that explained you shouldnt trust that damn thing anyway.you should hand calculate your mpg because it is more accurate that way.

Yep, normal.....

What is not normal is the dealer and Ford not being able to answer your question.

yea you might wanna find a new dealer for sure.

lol......you are moving zero miles and burning a bit of gas while at idle. If you really want to fix that problem just turn off the truck at the light and restart it when it turns green.

called Ford - clueless.

I hope that was not the case.... My 10 years old told me that " you must be moving in order to average to go up Dad"......... After 4 fill ups my lie o meter does not move from 17.1.....

It is rumored that tire wear is significantly reduced at stop lights as well. Green lights are still being evaluated.

Guys you are all mean.

But I have noticed that I'm not going anywhere, when stopped.
