Same here.   And i like to think of it as "Smiles per gallon" not miles per gallon.....

I forget the exact numbers but at the Charger Meet in Jefferson City a couple years back I used around 15 gallons in a little less than a hundred miles. That was mainly all city driving back and forth to the meet from the hotel. That figures out to around 6-7mpg and I never bothered to check it again since.

[y3chargerrt]

Mostly stock and 10-11 mph here.

9 to 10?  Sounds about right, and that's with keeping the motor under 3K...

[ITSA426]

I get a consistent 10mpg with 3.54 gears.  If it's on the trailer behind the Rumblebee it gets 12 but then I don't have room for the hemi.

[my73charger]

Mine does real bad, but I have 410 gears.  Somewhere around 5 mpg (in the city) I would guess.

When moving to Wa from Alaska, my Charger averaged 17mpg during the 3 day drive, packed full with luggage.....Stock 440/727/3.23.....doesn't get that now though....hahaha!

[tricky lugnuts]

Put a 440 in my Charger in January. Original, stock, '71 440 with electronic ignition; otherwise stock, standard bore.

Drive it close to 700 miles for a trip this winter. Got about 16-17 miles per gallon on the highway.

City mileage sucks -- probably about 10 or less.

It can get about as bad mileage as my foot wants it to!

Read in my factory service manual for '71 that a 440 sucks down 1/4 gallon of fuel every 10 minutes at idle.

Drove my 500 over to St. Louis last year for a show. 247 miles on 17.3 gallons of gas. That comes out to 14.27 miles to the gallon. That is a 440 AT with 4.10 gears. Was cruising at 60-62 mph all of the way over. Now on the way back home, was a different story. Drove back at around 70-75 mph and used 20.5 gallons of fuel. Which comes out to 12.04 mpg.

[RDR838]

Mine does 13 mpg on the Autobahn (@75mph/3.23gears that is - it seems not to be designed for constant faster speeds, especially the tranny would overheat quickly I was told)
Worst I had was 8mpg.


btw: My '94 Audi V6 gives me 18mpg @ 135mph 

[autodynamics]

i get around 20 on hwy....14-17 street

[Khyron]

I'll let ya know when it's running 

[bill440rt]

Gotta ask, does anyone here with a 440 REALLY worry about gas mileage?

how did you cruise 75 with a 440 and 4:10's? when i had them in my 69 i hit 75 once and it was right at 4000. felt like it would rip the motor apart if i held it there for a long trip.. not to mention i only got 6-7 mpg with 4:10 gears in mine. even on the interstate
it was fresh too

I just changed my gears out over the winter so I'm not sure. I'm doing a trip down to oregon in a couple weeks so I'll do some calculations then to see.

The only thing it's good to know for is to calculate the expenses to go to a show that's not in the engine-warm-up-phase-radius I guess...

Otherwise I count the smg (smiles per gallon) mentioned above 

[jwilk01]

When we drove down to tenn. I was getting around 18-20 mpg.  In town I have no idea.

Your right, it was humming along at around 3,900 rpm at 70 I think. It wasn't exactly the nicest thing to listen to humming in your ears for 3 1/2 hours, but it got me home right?

[hutch]

mine is 8mpg.

When these cars came out the speed limit on most US highways was 70 mph. So you shouldnt have any problems because og 75 mph.
