gas mileage

[Tranceformer]

What kind of gas mileage is everyone getting with their stock 2.73's??? I'm averaging about 14mpg around town with my 5-speed.

 

[HISSIN50]

i get 15 in town. most of it has to do with how hard you stand on the pedal.

while a bit low, that does not sound too unreasonable (depending upon how spirited your gas foot is. ).

Ya Don't worry about it, in town these cars lick, but once on the highway its awesome mileage if u have stock gears. I have 3.08's and its getting better mileage than my old 4 cyl ranger on the highway.

I get about 17 with city/hard driving and about 25 highway/easy driving with the stock 3.08's.

Just filled up 10 minutes ago - 9.9 gallons on 216.7 miles - 21.9 mpg. Most of that has been easy cruising miles around town with little stop and go traffic. Mine routinely gets 18-20 around town, and 24-26 on the highway running about 65 mph. That's with 3.73's and 'brick'-like aerodynamics. Oh yeah - 5 speed, and mild H/C/I - about 280HP and 335 lb-ft at the crank.

Michael, i wish i saw your milage. this speaks well for your tip top state of tune.

:OT: i thought you were running something comparable to a 3.90 rear gear in your Dana?

 

[Michael Yount]

3.73's (my gear - 41 tooth ring/11 tooth pinion) with a 225/50/16 tire (my size) is like a 3.89 with a 225/55/16 (Stang size) tire.

JT - it also speaks to a mild cam, and lots of low end torque.

ahhh so. you got me crosswired (only the ~3.90 spec had stuck in my bean).

i have always wondered how hard you stand on it around town, when you are churning those nice gas figures. i suppose with a 'little' more power in tap and gearing as such, you dont need to stand on it as much as some of us to move at the same rate.

thanks for the clarification.

 

[Michael Yount]

The car starts off in 2nd gear with little drama. 4th gear works quite well from about 20-25 mph up to about 102 mph. However, it takes a bit more throttle opening at 102 than at 25.

The 2.73 once got 26 MPG highway, but averaged around 23 MPG. With a 4.10, I get 19-20 MPG highway, and with the old 3.55 20-21 highway.

I should note that the 2.73 milage was with a stock motor. The 3.55 and 4.10 milage is with the motor as it sits now...

I am gettin about a 13.5 on the highway with my 2.73, a 5spd, and worn out 225/55/16 tire

Your car obviously has issues then... Change the O2 sensors to assure they're not running in open-loop all the time...

 

[Michael Yount]

mrcmk - I agree with pony car - a stock 94 ought to knock down at least 20 mpg on the highway without trying too hard, especially with the long gears. Something's not right....

Holy crap dude. At over $2 a gallon you must be dirt poor. LOL My mileage in town sucks. Somewhere around 13 or 14 mpg. On the highway.... I get about 225 mile on the OD when the gas guage hits 1/4. So somewhere between 25 - 30 mpg.

Michael Yount, list your mods please. Thanks man

if i may ask, what is your milage in town?

 

[Michael Yount]

Daggar - "I get about 225 mile on the OD when the gas guage hits 1/4. So somewhere between 25 - 30 mpg." Certainly at some point you've actually topped it up and done the math, rather than relying on that notoriously inaccurate gas gauge.

domestic - Y303 heads; 1.7 RR; 65mm t/b; 75mm ProM; 1 5/8 shorties; Explorer/GT40 intake; Buddy Rawls custom cam; stock injectors; stock 91 bottom end; T5Z with the .625 5th gear, instead of the T5's .675

18 in town, 25 on the road. That was before the heads and intake dropped it to about 20. I'm not home now, so we'll be trying to solve that problem when I return to the states in December.
