I can't believe you guys getting 25...

On the highway I get between 21-22 and that is running with the cruise control on and staying within 5 mph of the speed limit...

One time I tried it with not using the cruise control so it wouldn't adjust speed so quickly and I stayed behind other vehicles so as to let them cut the wind for me and I I got a little over 23. But no way do I want all the pebbles and stuff bouncing off my car from their rear tires... I tried it once for the sake of seeing what the car can get but it wont happen again... I will pay for the extra gas to keep my car "perty"!

I drive a good little trek back and forth to work and I get between 17 and 20 depending on how much "enjoyment" I get out of my drive... I luv the car so I will deal with the gas mileage!

 

I dont count it when Im tromping on it. I dont drive in rush hour traffic, work from home. Most of my driving is freeway, lots on cruise control. I have a RT with the Hemi and about 8,000 miles. Only mods is removal of resonators. The very worse ive gotten was around 18, but mostly over 25 mpg. My best was 27+. Im going by the built in economy computer in the cluster screen. On an interstate trip, I towed a car dolly with a Ferrari 308 from Columbus to Pittsburg and reset the computer for the trip and it indicated 20+ with the tow. Im also usually alone, no passengers. I also keep the trans locked into just 3 gears if around town, 4th usually and only use 5th when on a highway. I use 35 pnds in stock tires. I also rarely use A/C.

 

Also remember the V6s have 17" wheels (stock), lower geared rear axle, and only 4 gears (RT has 5), and only the Hemi has MDS. The 5.7 Hemi in the trucks is different than the Magnum and you will be very lucky to get 16-18 mpg. ( or around 10 less than you get with the Magnum RT). From people I talk too, I get better mileage than any V6 owner is getting.

 

I wanted to post my experience with my '07 SXT with the 18 inch wheel option.
I am quite disappointed with the in-town mileage...of course, its hard to compare
one guy's in town with another due to traffic density, driving style, etc.

I commute 1.6 miles to my office and poke around town from time to time. I am driving
as easy as I can and trying to stay in the tallest gear possible.

My first tank of 87 octane gave me 13.4 mpg. The second tank gave me 14 mpg. My third tank is 89 octane so
I'll have to see how that works.

My guess is that until the car warms up its running pretty rich to try to heat the catalytic muffler up and so uses
a lot of gas. Additionally, California winter gas has some ethanol in it and there is a mileage penalty to that.
On the highway I should be able to get 26mpg. I base this on a 2005 sxt I rented and drove from
So. CA. to Denver and back(around 2000 miles). The '07 magnums have a 5 speed box so that should help
the mileage a bit.

I had no idea that the in town mileage was going to be so bad. The car I sold, a 1966 Thunderbird with
a 390 cu. in. V8 and Cruiseomatic(3-speed auto) under the same driving conditions could get 12 mpg. This was a
4200 lb car that was considerably more powerful (315 hp) and had none of the computer controlled, high tech
stuff that the SXT has. Further, the SXT's motor is only 217 cu inches and is really a pretty small motor.

I really want good in-town gas mileage just because but since I do not drive many total miles/year
it really isn't a big deal.

And except for this one complaint I really like everything about the car( except the finish of some of the
engine castings...I guess the bean counters wouldn't spend 50 cents to sandblast the mold marks off of them).

 

2007 R/T AWD AND I DON'T WORRY ABOUT GAS MILAGE I PUT GAS IN AND ENJOY THE RIDE. IF I WAS TO WORRY ABOUT IT I WOULD GET A "GEO" AND BOUNCE UP AND DOWN THE HIGHWAY

 

I have an 05 Magnum R/T . I have a K&N CAI and Magnaflow Exhaust. In the city I get about 17-18mph and the Highway about 25mph @ 70.00mph. I did notice a little better fuel economy when I put the K&N CAI on. About .5- 1.0 mph better depending on the driving conditions.

 

I have an '05 RT AWD. In the interest of full disclosure, my numbers come mostly from the cars own computer so take it for what its worth. I've done a few manual measurement and they matched the computer. I usually get about what the original poster (AJ_Gil) gets, around 16 in town and 22 on the freeway. However, I have gotten as high as 26 mpg driving from Colorado Springs to Denver (multiple times). This was no A/C and driving only 60-65. Getting the speed above 65 apparently really starts to effect mileage. That same trip at 75 and I'll get 21mpg. On a trip from Colorado Springs to St. Louis, driving 80 and with a luggage box on the roof, I only got 18. (That was kinda disappointing.)

'05 RT AWD (Mineral Gray)

 

06Magnum R/T AWD, my first few 1000km's I was getting around 13 to 15 MPG city driving and on the highway around 19 to 21mpg. Once I hit over 30,000 km on my mileage has been around 14 to 16.5 MPG city driving and highway I have really noticed a difference as I typically avg. 21 to 23.5MPG with avg speed of 100 to 120 km/hr. I have tried varying from 87 Octane to 89 Octane and found no difference in fuel economy and have stuck with 87 Octane.

 

from the bottom of the Ram Pickup MPG Improvement FAQ:
----
In the Cummins White Paper they cite a study where there was a 30% variation
in MPG between professional drivers in the exact same truck over the same
route.

This is similar to GM research, such as this from from page A3 of The
Wall St Journal on 11-21-2005:
"Roger Clark, GM's senior manager of energy and drive quality in North
America, said the current test does a good job measuring average mileage but
the problem is the variation in how people drive. He cited a GM Study of 209
people driving the same midsize SUV. The fuel economy varied from about 13
miles per gallon to 23 miles per gallon, depending on the driver."

Oak Ridge National Laboratory found similar results:
"The problem is that mileage varies so much from one driver to another and one
place to another that the government ratings are a poor predictor of what any
individual driver is likely to get with his or her vehicle," said Bo
Saulsbury, a researcher at Oak Ridge. "If the EPA rates a car at 20 m.p.g.,
the real-world data show that you might do as well as 30 m.p.g. or as poorly
as 10 m.p.g."

Ford did a test of different drivers in the same vehicles and found an even
greater MPG difference of 38% between the best and worst driver habits and
conditions like low pressure tires, max AC, cargo on roof racks, etc:

There are 'experts' at driving to get the best MPG. You can read about
John and Helen Taylor, a husband & wife couple who are sponsored by
Shell and have won many contests at this link:

Note the list of good driving techniques for better MPG near the end of the
article about the Taylors.

At the far 'extreme' there are also guys known as Hypermilers
such as Wayne Gerdes:
