I've had my magnum for about 6 1/2 months now and am completely in love with it. I don't drive very often as I work from home but have put on about 7500 miles thus far, so it's still pretty immaculate. Unlike the poster above who has had mileage problems from the start, this Magnum has been flawless, and aside from the first 500 miles of driving slow, it's been a dream, and the MPG has been very consistent. The vast majority of my driving is on the highway, travelling 55-75 MPH, and I average around 22-24mpg on the highway. If I use the cruise control on a long empty stretch of road I've gotten as high as 26mpg. When I'm in the city it drops down significantly to around 15-17, but at that point I'm usually just enjoying the car - the speed it takes off is just SUCH A RUSH, I love the beautiful purr of this motor. Not a single thing has gone wrong with this thus far and I just couldn't be happier. I'm glad I took the advice from the people on this forum and bought the RWD instead of AWD; though the wet-weather traction seems a BIT lacking, so when it comes time to replace the tires, I'll probably go with a more wet-weather-friendly tire, as I live in rainy South Florida. Peace! |

| I've had my used 05 for a month and I've put over 5,000 miles on it. Just drove it from Michigan to New Orleans and I averaged around 20-22 mpg running hard at 85 mph. In town I'm getting 16-18 mpg...a little disappointing since my 01 Deville with the Northstar was getting those numbers. In fact, I could average 24 mpg in the Caddy on the highway running just as hard. But, you can't beat the looks of the Magnum. I was hoping for a bit better mileage.... | |
Did anyone try premium, and why manuf. wants only 89. From my experience all cars run better on 93 or up

Replying to: kecaj (Apr 13, 2007 8:20 am) My 2005 R/T AWD with an AFE cold air intake gets 22-23mpg on the highway when cruising between 65mph and 75mph. At 80mph and above I get 19mpg. Around town I get 16mpg to 18mpg. While the gas mileage is not good compare to my previous car, a Saab 9-5 Aero Wagon, the Hemi is just too much fun. As a volunteer firefighter it gets me to the fire house real fast!

Replying to: bbfd86 (Sep 05, 2007 4:46 am) Dodge recommends removing the roof rack cross bars when you are not using them. The principal determinant of fuel mileage is vehicle weight, regardless of all other factors (of course, hybrids are a special case). Notice that the 3.5 V6 and the 5.7 V-8 get identical mileage (if driven in an identical manner). Once you stick your foot into it, that's another story. |

About the octane: The manual warns that heavy detonation can damage the engine (duh!). But the brochures say that the Hemi, at least, has two detonation sensors, so that shouldn't be a problem. I don't hear any detonation with my '06 Hemi. (My '87 Grand National has a detonation sensor, also, and retards the spark if it senses any. You lose a little power with lower octane gas, but no harm done). |

| I have an SRT8Magnum and get almost 21 mpg at a steady 75 mph. In town if I am getting on it, I get about 12 mpg. | |

| Over the summer I did a trip with my 3.5 SXT covering nearly 4000 miles over 6 weeks. In brutally hot summer weather on the prairies at 110-120 kph ( 70-75mph) I got 31.82 miles per gallon on regular gas with AC on . Had I slowed down I'm sure it would be higher. I did move to synthetic oil (Castrol GTX) and swapped out to a low restriction air filter. Now that it is being discontinued I know I will never get rid of it. It is too much fun. | |

Replying to: pf_flyer (Jun 12, 2006 8:07 am) On limited hwy miles, I have gotten around 21-22 MPG at 65-70 MPH (so much for the 4-cylinder shutdown mode). Compared to this car, my '87 Buick Grand National is an economy car. Like someone said, if I get my foot into it with the Grand National, mileage suffers, but I could easily get 18-20 all-around if I lay off of the turbo. These Magnum numbers are WAY below even the revised, lower EPA figures. One thing I noticed is that there is soot in the tailpipes of my Magnum (none of my other modern cars do this). You can feel it with your fingers, it is a greasy-feeling black powder. Soot, not oil. I think that I am going to take the car to an independent shop and ask him about this; maybe have him run an exhaust-gas analysis. If he doesn't have an analyzer, I think that I might pay for a full emissions test (with the all-wheel drive, it will only be a two-point idle test, since they can't do a full dynamometer test with AWD). I also have a new 2007 Toyota Sienna (minivan). Both cars weigh about 4,200 lbs. Of course, the hemi is a larger engine, and is geared down a little more. Then there is the issue of the increased friction of the AWD system. Still, I can easily get 18 mpg with the Sienna with just a bit of hwy miles mixed in, and can get 24 MPG cruising at 70-75 MPH. Remember, the Sienna is both much higher and wider than the (narrow) Magnum, so the frontal area is much greater. So the disparity in mileage just doesn't make any sense. To me (a virtual lifelong car guy and mechanical engineer), the critical clue is the exhaust pipe soot. I am going to have that investigated.

Replying to: midnightblumag (Oct 07, 2005 7:28 am)  60-70. I find the trip advisor states I am getting better milage when driving a little harder. But judging from reports I see others are getting closer to 23 my 65ish speed. Any comments or updates?
