Manual MPG vs Info Center MPG

[ls973800]

I have always used the info center mpg calculations and was very pleased to see an average of 22-24 mpg per tank. This is mainly freeway driving, not too much city stop and go. In the last several months, thanks to some information posted on this forum, I was able to find how to display an enhanced info which includes mpg, gallons used, hours running, etc.

 

I have noticed that I can always get at least 1-1.5 gallons more into the tank than what the display says I used. Yesterday, I put just a little over 2 more gallons in, and this was not to the point where it was spilling out of the filler tube. My display said I used 10 something, I put in over 12 gallons. That is over 20% more than what it says I used! My mpg display said 23 but my hand calculation said 20.3 with the amount of fuel I used.

 

Not feeling so good anymore about the REAL mpg I am getting, especially since the display is over 10% off on mpg, and 20% off on gallons used.

 

I really don't know if there is anything the dealer can do to correct this. I've seen similar posts about the same inaccurate readings, but never saw if there was a fix.

 

I guess from now on I will be keeping a close eye and recording the differences, so that next time I'm at the dealer I can at least document the problem.

which forum is the display info in? Does it matter what model Edge it is??

I always calculate by hand and see better mileage than what mft shows.

Edgieguy,

What I was asking is where you got the information how to display the enchanced info in your display center? Hours running, gallons used, time at idle etc.

 

Thanks

On page 114 of my owner's manual, it shows how to navigate through the different display choices for my duel screen displays. Page 116 shows how to choose the enhanced features for the fuel, time, gallons used, etc. I have a 2013 Limited with Sync and My Ford Touch. I'm not sure what option you have for your Edge or if you just have the single screen display above the steering wheel.

 

If you have just the single screen, page 108-109 of my owner's manual shows there may be the enhanced settings for fuel used, trip time, etc. It looks like you have to scroll through each reading, whereas on mine once I select enhanced, all the information is displayed at once on the left screen. No need for me to scroll to each individual reading.

 

Mine has to the right of the steering wheel an info screen for climate, navigation, entertainment, and phone.

 

To the left of the steering wheel is another info screen, which shows selections including Display Mode, Trip 1 & 2, Fuel Economy, Settings, and Information. This is the screen you use to find the enhanced fuel readings.

 

You will actually go into the Trip 1 & 2 menu, not the Fuel Economy setting where you would think it would be. In the Trip 1 & 2 menu, select standard display or enhanced display. Standard will only show trip distance and elapsed trip time. Enhanced will show trip distance, elapsed trip time, average fuel economy, estimated amount of fuel consumed, and total odometer.

 

What I like about the elapsed trip time is that it is actually an hour meter which runs whenever the engine is running. It stops when you shut off the car, and continues again from the last reading when you start it up again. You can reset it whenever you want back to 0 hours and minutes. I use trip 2 to accumulate miles and hours/minutes until I do my next oil change. I only reset trip 2 when I do an oil change (every 5000 miles). This gives me a good record of engine hours, miles driven, and MPG average over those 5000 or so miles.

Were you able to find if your Edge has the enhanced display?

So I filled up for the first time since I reported the huge difference between the amount of fuel I refilled with and the MPG computer reading versus my hand calculation as I posted in the original post above. I filled up at a different station, and was only able to get about .3 gallons more into the tank than what the computer said I actually used. My MPG figures were also within .2 MPG of each other.

 

Either the last station I filled up at had an out of spec pump, or there was some type of glitch with my last readings. Much happier to see that I actually did achieve almost 24MPG this last fill up.

Variables & variability!!! Bane of those seeking accurate information

I guess. I'll just stick with what the computer shows for MPG since that has been in my happy zone. :hyper:

i wish my 08 had the average mpg display. i have an app on my phone and a bluetooth adapter. it shows all kinds of stuff like instant mpg and average mpg. i was looking at it last night and it was saying my average was between 29-30. when i filled up this morning, i figured it at 22.1mpg. that is a mix of highway and traffic driving.

My feelings about mpg on my 2011 Edge and any other car I have ever owned:

 

What are you going to do if you don't like the numbers?

 

Take it back to the dealer and demand a replacement that gets better mpg?

 

Drive it off a cliff?

 

Drive it into a river?

 

That's why I don't even check my numbers anymore.

 

It's like worrying about tomorrow's weather.

 

Just my $0.02.
