I get about 17 on average.

 

Set a new record for my car this past weekend.

Driving from Allen to Corsicana in Texas I managed to squeeze out 34.5MPG with speeds hovering between 75 and 80mph pretty much the whole way.

Allen all the way down to Houston (Including the stop in Corsicana) I averaged 31.4 mpg for the trip with speeds of 75 to 80mph.

Round trip including some city driving in Houston and using the A/C all the way back to Dallas with speeds touching 85mph at times I still ended with 28.9 mpg average.



It makes my wife mad knowing my car can exceed the fuel mileage she gets in her i4 Camry.

 

 

Just bought my 2012 GT and drove from Michigan back to South Georgia. I averaged anywhere from 23.5-24.9 95% highway 5% city. Driving between 75-80 the whole way. Not bad, IMO, with 3.73 gears and the 5.0

 

5.0L, Auto w/3.15 gears. It's the Wifey's car, so the only time it gets to stretch it's legs is when I drive it by myself. Which is a rare occasion. Overall avg. 20.2 with 6200 miles on the odo. She test drove the V6, and liked the car. I suggested test driving the 5.0, and she smiled from ear to ear. So, there ya go.

 

My car is an '86 5.0 coupe w/ a 5-spd and 3.73 gears. Power mods include CAI, cam, headers and exhaust. I average 14-15 MPG in the city, and have gotten as high as 20 MPG on a pure highway run averaging 75-80 MPH with no traffic.

 

My '07 V6 Pony auto - with mods - avg. 19 MPG.

 

I've happend to manage 32 mpg is that likely for an 06 gt to get that good of mileage?

 

My car hasn't seen the highway in months. I drive it once a week and city speeds only

 

Just picked up my '14 about 1 week ago. It's only got 220 miles on it thus far and I'm only averaging around 15mpg. It's a v6 lol.. Ive definitely stomped on it a little, but **** haha. Hopefully this improves with time
