I am about 550 miles into my Fiesta ST ownership, and it seems like my MPG gauge seems to finally have leveled out. However, this is very concerning because it has flattened at about 24 MPG. most of my driving is Highway and during my commute i definitely try to nanny it, shifting before 2 grand. This is my first manual car, so i wouldn't be surprised if I'm doing something wrong, but I would at least like to get to the low end of what the sticker fuel economy is during my commute. does anyone have any experience in this? what kind of MPG are people seeing?

I reset mine after each tank, I haven't tracked overall average, but I'm usually about 33mpg (lowest I've had for a tank was 26, highest 38). 24 for mostly highway seems pretty low based on my experience. Might want to check tire pressures and alignment, and speed. 65mph is noticeably more efficient than 75mph. Not saying you should slow down, just that it might be a contributing factor.

 

[RevinRed302]

hmmm. odd. would there be an easy way to check my alignment? I'm not all that good a wrench.

 

[Cesso]

Get a professional with the right equipment to check your alignment if you want to do so, there is no DIY way. I don't ever check what the trip computer tells me my MPG is, I think it usually reads 20-22. I calculate the average from each tank so I know exactly what I get, so far I have gotten 24MPG consistently with 100% city driving, and going pretty hard on the gas pedal.

I'm currently getting overall 32.8 mpg (93 octane) with 75% somewhat aggressive highway driving mostly on the weekends; I did the Break-in 101 thing - easy does it for first 1500 miles w/rpm variance, etc., and have already changed the oil twice and the transmission oil once (I'm currently at ~2400 miles) so maybe that helped, but who knows?

Congrats on your new ST!

Per your Owner Guide:

Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine’s break-in period); a more accurate measurement is obtained after 2000 miles - 3000 miles (3200 kilometers - 4800 kilometers). Also, fuel expense, frequency of fill ups or fuel gauge readings are not accurate ways to measure fuel economy.

I hope this helps clarify things.

I just pickup mine up a month ago, and the fuel economy was not what I had bopped (in the beginning at least). How do I go about resetting it?

 

[Ca5p3r]

either use the push stick in the bottom right area of the tach or use the button on the end of the turning signal stalk.

press to cycle through odometer, mpg, trip, etc. When you are on the particular one that you want to reset, press and hold button

 

[Mister_Mino]

How fast are you driving on the freeway? I've gotten as high as 38+ when I stay around 62 but it will drop to high 20s at 80mph.

 

[RevinRed302]

I stay around 65 as well. it has crept up to 26 since i posted, but that's still not great. im assuming that its becasue of what the Ford rep above said.

 

[Mister_Mino]

do you reset your MPG every time you fill up?

 

[RevinRed302]

I have not.

 

[Mister_Mino]

I would suggest resetting it then driving some more miles to see where it settles at again.

 

[RevinRed302]

I think Ill try that once i hit 1000 miles

 

[Mister_Mino]

I can never mirror my driving tank to tank as my city and highway and driving style are all way too inconsistent. I'm sure over 1,000 miles you are getting an accurate average but one extra highway trip or one extra city trip and you're not at an accurate comparison before and after. Last summer for 1000+ miles with a lot of autocrossing and a lot of highway miles I only averaged 21mpg.

 

[ted lorendo]

With cobb stage 3 and a protune, I consistently get 31.7. That's hilly driving in a mixture of city and highway .

 

[hollywood]

My readout says 30.3 with combined city/hwy driving, however I'm running 205/45/17 tires, so my tires are covering a slightly longer distance than what the computer thinks they are. Probably averaging 31-32. I get 36 on the stock tires if it's strictly highway driving.

 

[Ben]

I'm getting about 7L /100km (About 32 MPG), which is a lot better than I did in the first thousand miles. That's with some good acceleration and city driving mixed in.

Its all about that "good acceleration"

 

[Cesso]

Just calculated my last tank with half a tank of city driving, one full-throttle hillclimb from 5,500ft to 10,700ft (as well as an aggressive descent), some highway cruising, and a spirited mountain road drive : 30.03mpg. Damn I love this car.
