I get 22 in the city....that's figuring it the old fashion way. The instrument data is close. It says I average 25 mpg on a tank. I haven't calculated highway miles as most of my driving has been in the city.

 

I probably average 16-20 mpg in the city depending on the weight of my foot, something like 22-25 on the highway...average speed on the highway = 80ish

and steelstang why is it your last post?

 

My mileage has been crap lately... most recently 17.5mpg mixed! [:'(]

I average about 22mpg mixed.

 

I'm getting 12.4 right now....not driving hard or anything. What is up with this? I think its the ethanol crap they put in the gas over the winter is making the car run like crap....anyone else experiencing this?

 

Interesting. You guys and those guys ought to get your stories straight...[/align][/align]https://mustangforums.com/m_4347084/tm.htm[/align]

 

about 17, mostly bumper to bumper in city traffic. i hate rush hour

 

Our 4.0 auto gets between 24 and 28 mpg depending on type of driving. Interestingly, about the same fuel economy as my '04 GT manual.

 

That is pretty low. Heck, my Conversion Van gets 13 mpg and it's a boat! I know the gas I buy contains 10% Ethanol and I buy regular gas not the high octane.
Check your tire pressure make sure they are up to par. Sometimes low pressure will hurt your mph. When's the last time your car was serviced? It might be time for a tune up.

 

I average about 21-23 with alot of spirited driving in mixed conditions and I need tiresfrom too many spirited takeoffs. I probably average 75mph hwy and 65 on regular roads. The only all highway trips I've taken I averaged about 26mpg (Louisville, KY - Orlando, FL~2200 mi round tripand Louisville - Bowling Green, KY~180mi round trip)

 

lately i been getting between 17-19 mpg's mixed driving. not very impressive but i blame it on the torq tune[8D].
