Just curious, what kind of fuel mileage is everyone getting. I have an 07 Ram, club cab with 8 foot bed. I am also running with a canopy. I am getting an average (hand calculated) of 17MPG. When towing my 24" enclosed car trailer I'm getting 13 MPG average. Running a EZ.

I should of included that my truck id 4WD.

 

18-19 mpg

Same setup as you, but an 05, smarty on five, bfg muds, 285s and 90 percent highway driving,

 

18-19 on interstate and back and forth driving. doing 65ish all day with no hills and wind i have see 21-22

 

I'm 100% stock and can get 20+ mpg (hand calculated) if I keep it between 55-58 MPH, at 70 MPH in the 18 mpg range.

 

I have a spread sheet of my 279 fillups (and other maintenance as well) that confirms IU get exactly what DBLR gets. In the winter subtract 5% ish.

 

Before water pump change out (the other was leaking) about 12mpg city and now 15mpg city. Speeds between 40 - 60 rural hwy's to and from work. 100% stock.

 

Last fill up got 19.2 hand calc.

 

19.5 Normally.

 

19.5-20.5 consistantly, hand calculated, filling tank until pump shuts off, then let the foam subside, then do that a bunch more times to get a few more gallons in.
If I stopped the first time the pump shut off I'd probably be at 21 MPG.

 

i though i was the only one to do that, i can get 2-3 more gallons in if you have the time.

my 99 you cant do that.

99 is around 17-18
03 is around 19-20
i dont check MPG every time.

 

How about an overall average people?

My OA is 16.5mpg

Hwy best 20.7 - usually 17-19
City worst 12.2 - usually 14-16

 

Yep, OA for all driving,(town,hwy,empty,and towing mixed wts.) in five years = 15.974 MPG. I keep a runing record on gas buddy.com.

 

Order of importance on mpg:

- Truck specification
- Climate
- Terrain
- Truck Use

After that, as Shorts indicates, it's the average mpg that counts. Highs or lows are too easily manipulated. It is not a basis for comparison as -- in the end -- it comes down to the gallons purchased to cover the miles travelled (and that includes extended idle time where mpg is not zero, but negative).

How much am I spending for every mile?

Cents-per-mile is handy for predictive purposes. How much will it cost in fuel to travel X-miles?

So, the purchase price of fuel over an expected trip length is useful. If my fuel cost is Y-cents per mile then it's easy.

What's my mpg then, (as above) doesn't mean much. What's my fuel cost per mile . . now you're getting somewhere.

I can tell you my average is 22-mpg, but the useful number is that fuel costs me (while solo) 15-cpm.

If I make a run to San'tonio of 312-miles, then I'll spend right at $47. (312 X .15) at the present price of $4/gl.

- Compare the average mpg
- Look at differences of spec, climate, etc
- See where the fuel cost is the real clincher

If Shorts is averaging 15-mpg, then the cpm is 26-cpm. Highway will be a bit lower, and all city a bit higher than this. But it's still a good number to use to see what my out-of-pocket expense will be. That's what counts.

If I drive 12,000-miles annually, then at 15-mpg, or, 26-cpm on average, my fuel cost will be $3,900.

Etc.

My old 2001 2500 4x4 auto got 15-17.5 empty, pulling 8.5k toy hauler 10, 2004.5 gets 12-14 empty, 11 pulling toy hauler. All hand calculated

Just to nitpick. If ones displacement is 0 (not moving) your denominator can be anything >0 and 0 is the result. Speed (MPH) is a scalar quantity, not a vector, and is understood to be an absolute value. So even if you coast backwards at idle your MPG will be positive because the numerator will always be positive.
