also, i am a big proponent like others on here of calculating the MPG by hand. it's more realistic since not depending on the computer at all. a great way to do it is to set up a spreadsheet and keep a running tally. i am really anal keeping track of all of that for my car: miles driven, total fuel fillup, MPG, average MPG, cost per mile driven, average cost per mile driven, etc.

Bingo! I've been doing this "anal" thing for many years and now it's just a habit. With smart phones and such it's even easier to keep track.

Hope this helps.
The MPG dash readout is only an approximate number. You really have to record your mileage and gallons per tank refill to get an accurate mileage reading - and of course there is a lot of variance with where and how you drive.

It's a 16 gallon tank. You have an odometer. Pretty easy to figure the rest out for yourself

I'm sure most people could probably just use Google or simply call Ford to get an answer instead of posting a question on this board, but people chose to post here instead.

Why do you appear to have an issue with my questions? You've contributed nothing but negativity in this thread. Once again, everyone is not the master technician that you obviously are. Some of us just wanna ask a GD question. Capiche?

Just disregard people like that. Some people do it all the time because of insecurity.

My mileage has got better with time.
If I'm easy on the gas, and cruising in 6th, I can keep city driving down to between 13-14 L/100km. Normal driving, and it goes up to 16.
On the highway, I'll see anywhere from 9-12, depending on speed, wind, elevation, etc.

This is a normal operating characteristic for your vehicle.

My vehicle is currently 13 L/100kms with only 3200kms on the clock and thats even pampering the girl. Even when I go on the highway (nothing over 2300 rpm) for a cruise out of town I'm still showing 13 L/100kms. Break in period maybe causes fuel consumption to be higher? I don't know but she seems abit hard at the moment on fuel considering what its rated for.

There's nothing negative about what I'm posting. I'm honestly just confused by your questions. Is it not faster and easier than asking others whether your car is reading accurately when we don't have access to your car? You came at me pretty hard when I responded the first time - going as far as to question my basic reading comprehension (but then rewording your statement for lack of clarity), so my responses have been in line with the tone our conversation has taken.

So while I can't tell you whether your car is behaving as you expect it to, I can tell you that 18mpg and the car "losing" a mile to E when idling in a driveway is perfectly normal.

Just a quick reminder about the mpg ratings, these are the EPA's numbers, not Ford numbers. The window sticker clearly states, "EPA Fuel Economy Estimates".

Also, the City estimated MPG is 17, but on the window sticker it clearly states, "Expected range for most drivers 14 to 20 MPG" and on the highway mpg of 26 it states "Expected range for most drivers 21 to 30 MPG".

That is true and it isn't. Each manufacturer does the tests themselves, by the EPA's testing guidelines. The EPA doesn't verify every result. They audit at random (10-15%).

Car tell's me I'm averaging 14.3 MPG. I don't redline, but I do bring the Tach to a bit over 6k regularly. The 3.73's don't help mpg either, but I didn't buy it for mpg.:yelpleased:

An obviously obvious statement, but the car has to be somewhere when the miles to empty changeover from one to the next.

I'd be doing cartwheels if mine was getting 17.9-18 mpg. But am I disappointed? No. It's not like I went in intent on buying a high-mileage Focus SE and the dealer pulled a fast one and slipped me a 412 hp Mustang GT instead.

If you love your dog, get a microchip, they really work! My lost dog was back home in just under 24 hours thanks to the good citizens who called the county and the microchip that told animal control exactly where he lived.

my '11 3.73 just turned 4255 miles.
I do lots of highway driving.
The mpg AVERAGE today is 20.0 mpg
Somewhere the owners manual says to wait until after 4,000 miles are on the car to start watching the mpg.

my 1st 1000 miles were around 18.0 mpg

It has been getting better it seems.

Also after it got to 19.8-20.00 mpg, I flog the heck out of this car and it hasnt slipped below 19.8 since.

And I agree with the post about idiling it will kill the mpg average.

Anyway my .02!!!!!
And yes these cars are awesome!!!!!!
