Poor gas mileage question

[Commbubba19]

That is high.. Did you adjust your AFE bias? Ford computers tend to read 1-2mpg higher than normal. Mine use to read that but now its 24mpg at 80mph/2100rpms with factory 3.15 gears on an Auto.

no but i’ve done random hand calculations and it’s been close.

today averaged 26.9mpg at 73mph with the a/c off. i lose 1-2 mpg when the a/c on.

I didn’t buy the car to be concerned or preoccupied about my MPG...

Brand new '19 GT - been using it for less than 1 month, and my average has been 12.9 miles/gallon.

Granted I am in Medellin (Colombia/South America), which is relatively hilly with smooth yet undulating roads (lots of fun to drive, but hard to do highway style aka boring, one gear, fixed speed driving).

The occasional long drives result in approx 15-16 mpg. But this car is so much fun to drive in these hilly roads - the perfect power/torque setup for these conditions (overtaking everyone at a whim is really satisfying).

16 is about what I expect for mixed city/highway driving. I averaged about 19 with a 2015 GT over a year of ownership including some track days and about 18 with very similar driving in a 2016 GT350. Very easy to get a little higher or lower depending on how exactly you drive the car.

My commute is short(3 miles) and lots of lights so if i drive "normal" I'll get about 14MPG, if I TRY to get good MPG I'll get about 16. When I drive like me I'll get 11.5. On longer highway drives I'll get mid to upper 20's.

I usually get 12 mpg driving on the streets 3 miles each way from home to work and back. It's crazy! I only have x-pipe, Roush axle back, and it's lowered.

It's the short distance that is killing your MPG.

What Elp_jc said! Trips that short are killer on fuel economy. For one thing, the engine never fully warms up in just three miles so the mixture is always a little on the rich side. That, coupled with stop and go driving and it's a miracle you're still getting in double digits!

That's true. Thanks for the info.
