poor mpg

Just bought a 2014 V6/auto. The sticker says 30mpg highway. I'm lucky to get 23. Is this normal?

Yep. Lol, if you baby it on the highway you should see it get very close to 30 in all seriousness. I'll average around 26-27 now but it always wasn't like that. I used to average 21-23 but I change my driving habits a little when I need better mpg.

I just bought one new at the beginning of the month and have about 700 miles on it now. The mileage has gone up about 2-3 mpg so far compared to when it was brand new with some break in (in the city, I haven't taken a highway trip with it yet).

Depends on the rear differential gear ratio you have as well. My 2011 V6 with 3:31 rear gears is averaging 22 to 23.6 MPG on the highway at an average of 70 MPH.

Recently installed Airaid CAI and my mileage went down. Even when lightly driving it is still worse. Will a tune help? (Although the cost of a tune buys a lot of gas.)

They say a tune will help but it didn't for me!

I got a 2014 V6, 2.73 gears and Airaid CAI. LOTS of hwy: 26mpg average.
You'll get a solid 30+ on highway only, based on a recent road trip.
But if you're doin a good amount of city driving, and hitting the gas a bit, 23 is right on the money.

Go for a K&N air filter inflate your tires to the right psi and use a good brand gas. I only use chevron on my cobra. Higher octane makes the car run better and cheap gas makes it run like **it.

I've had my '14 3.7 6spd for a month and the total average mileage is 25.6 mpg over the first 1500 miles. I drive roughly 80% highway/20% city. I also only run 100% gasoline (no ethanol) and 93 octane fuel.

On the highway I typically set my cruise at 62 Mph.

I have not noticed any increase in mpg as the car breaks in.

the other thing (besides driver mod) is I found out that the epa rating is done with the economy tires, the summer only tires will drop you down 1-2 mpg. Your number is typical. I do semi-rural for the majority of mine and am getting 23/24 (math). It is a bit dissapointing but the performance to economy ratio is great....enjoy I did use math and found the premum did increase mpg enough to even the cost per mile and use that for the performance increase.

18 inch nice wide P-Zero Nero tires

They may be good tires but I'm sure they are bad for fuel economy. My next tire will be Michelin Pilot Sports.
I have been keeping 36PSI in my tires and get 24/25 MPG around town. On a trip I got 34 MPG average at 70/75 MPH on the interstate.
I regularly don't worry about how many MPG I get. I just drive my car the way I like to and enjoy the ride. I use 87 octane all of the time.
Believet it or not this Mustang gets about the same Miles per Gallon I got with my Mini Cooper JCW with four cylinders. "BUT" I always had to use premium gas in that Mini.
I can't complain about a thing with my Mustang.

I just put on a set of these Michelin Pilot Sports...you'll like them a lot. Quieter than the P-Zero tires, but I did get 52K on those pirelli's.

Take it back Immediately and DEMAND a new car Under the Lemon Law in your State. Then buy a Focus and you will get that mileage your dreaming of.

#1 stop looking at the stupid mileage numbers on the dash and use math

#2 learn to drive differently to see anywhere close to epa numbers

I have to make a conscious effort everyday to modify my driving to reach epa #'s in my focus. It doesn't take much to start dropping mpg.

Just drive and enjoy the ride.

Turn off the dash item that tells you how many MPG your getting,
Just drive like you enjoy driving.
Fill it back up when about 1/4 tank left.

I'm sure you will be much happier and love your Mustang even more then you would worrying about MPG all the time.

Buy good gas and your mpgs will go up. Don't buy cheap *** ethanol gas with God knows what in it as additives. I only buy 100% ethanol free gas and I averaged 26-28 75% city driving in my 3.7 and I average 20-22 in the boss and I drive it harder.

You get what you pay for, you wouldn't put cheap used Walmart oil in your car would you? Then why would you put the cheapest gas in it?

I've done a few tests with ethanol free and the small increase in mileage isn't worth the additional price.

Also nothing wrong with cheap oil as long as you change it regularly.

He is correct on this one. A lot of the oil when you get down to it depends on the filter.However, that's a different debate entirely.

Look at your driving habits use the pen and paper although the computer is fairly accurate you should try to do it by pen and paper to get a precise answer over a 3-6 month period. I find the computer to be within 1-3 mpg.

Also when the EPA tests cars they put them on a dynamometer so the results are skewed slightly. On the 4.0-liter I average 21.5 city/hwy.

I bet more often than not you find yourself digging into the throttle. The Mustang has that tendency

Yeah I don't know that I've ever seen 100% ethanol-free gas around my parts either. Maybe I just haven't looked hard enough though.
