Magnum 5.7L V8 Owners-What's your fuel economy???

[Arch Stanton]

42,000 miles gets 21 city 31 hwy

With all due respect, I find that awfully hard to believe.

I'm with ya. Then maybe the 6 threads he started for each of the cars (which are identical in economy and performance) will quietly go away.

They probably will after tomorrow, but someone else is bound to dig these up again with a single reply.

Actually, I don't think the problem is with the AWD Hemi... I think it's with the weight of my right foot!

That can certainly affect it too, but I was just being polite and not coming out and saying it.

I get about 19 with my RWD R/T. I only do 30 miles a day and most of that is city driving. I get about 330 a tank of 91 octane.

Long trips highway driving 22 around town which is most of the time 12 or 13

Well believe it Arch Stanton , I check it every tank, those numbers are of course not driving like a mad man.
When we got the car, we had it for a week then went on a 4000 mile road trip, which most was hwy driving.
If I was getting the MPG that a lot of you are getting I wouldn't be driving it, because there are many other cars for the same amount of money that are as fast or faster getting better MPG than others reporting here in the forum.
I have talked to other LX owners here that have 5.7s and several of them have had comparable MPG like 20 city 30 hwy.
I think that a lot of the LXs that report bad MPG, relate to many other things:
1. how the car was broken in
2. poor driving habits
3. maintenance, IE, air filter, tire pressure, spark plugs
4. extra crap they lug around in there car
5. ETC.
there are so many factors involved, and yes when I drive her hard she sucks the fuel like a kid drinkin soda pop with free refills.

dave,
I agree driving habits and all of the factors you mentioned contribute to your results. However,I had my first Mag RWD R/T two years (5,500 miles) It always got 12.2-12.3 as a daily driver,though I only drove six miles a day. road it would get 23-24 at 75 mph. I have had my AWD R/T for a year now (2,500 miles) and it is consistent 11.4-11.8 doing the same routine,seldom get on it due to conditions?? It got the same before mods and with mods.

No doubt that driving habits have a lot to do with it - especially with city mileage. For some, "city driving" means very little stop-n-go, but for others it means nothing but. I know what I get on my commute changes very very dramatically if I get stuck in traffic versus if I get a clear shot around the tollway.

I maintain my car and really don't get on the throttle terribly much when I'm cruising down the highway. Either you're just extremely lucky Dave or you're doing something that none of the rest of us are to be getting 25% over and above EPA estimates on the highway (and the same as the 4cyl R/T Caliber for that matter). I know I'd love to be able to get nearly 500 miles out of a tank of gas too. You need to fill us all in on what exactly you are doing to be getting that much from a gallon.
