Can someone give me some real life figures on gas mileage comparison between a 4.7 lt and 5.7 hemi in a 4x4 quad cab 1500. I know theres a lot of variables but just a rough ave. of each engine maybe? What i kmight expect? 2004-2005

 

According to fuelly, I'm averaging 15 mpg. The mileage, gallons, and relative info is always entered into fuelly before I pull away from the pump at every fill up.
This is on a 2002 Ram 1500 QC, with 4.7 liter, 5 speed auto and 3:55 gears.

 

I have a ram 1500 4x2 and if I drive carefully ill get 17 to 22. The reason it can get
So low is because of when I accelerate it guzzles fuel. I find if I just accel fast I
Don't waste as much fuel

But yeah in the city stop and go like 10 mpg lol

 

Oh srry, its a 5.7l hemi

 

I will move this to the 3rd generation section (2002-2008 Rams), get you additional help.

 

4,7's ......5.7's ......lol.

Couldn't resist.

By most accounts, the fuel economy is about identical in those years, with the Hemi even tending to be a bit better after MDS debuted in '06...

 

What is a "fuelly"? I hate to ask but I've never seen that word.

Anyway, got the 5.7, and I'm getting around 12 around town. I don't have any long trips or extensive highway driving to compare.

 

Hammer is right on about the 4.7's havig pratically the same mpg's as the 5.7L.

iphone or android app.

2008 4x4 QC w/3:92 gears
5.7L Hemi getting 12/13mpg city 15/16 highway. I'm Superchips tuned w/mds disabled.
My window sticker says 13city/17highway so it's right on.

with mds enabled I could get 18mpg but it was downshifting/up****ing constantly. Not good for the trans at all IMO.

 

I believe the "fuelly".....is his trip computer???
