Thinking of trading trucks and wondering what kind of fuel mileage you guys are getting on a new Dodge with automatic and 3.73 gears?

 

Hi. Im getting 14 on a good day with the 6.7 in a 3500 dually with the rear end ratio being 3.73.. Im Not impressed

I get 14-21 on my dually w/3:73's
9-13 pulling my 12000# 5th wheel

 

Im getting 14.3 hand caculated on my 2006 5.9 drw

 

Is that city or HWY?

 

Drove 450 km today, mostly highway, at 120-125 kph (75 mph) and averaged 15L 100 KM (15.7 mpg US, 18.8 mpg Imp). Now have 1500km (950 miles) on the truck.

I'm sure it would be better at lower speeds. At 90 kph (55 mph) I show 13 l/100 (18 mpg US, 22 mpg Imp)

I have not hand calc'd these. These numbers are from the overhead display.

 

Hand calc'd I'm getting 18.5 HWY at 68 MPH city - forget it it - too depressing to post........(about 9)

 

I get 16.5 mostly town driving and got 13 towing 11m lbs for 2500 miles , all hand calculated. EGR unplugged.

 

That would be city and highway. daily 40 miles highway and 14 miles city. drove it 430 miles in one tank and put in 29 gallons

 

13 hand calculated with mixed hwy and city driving.

 

Thanks guys, I'm getting on my 95 20 mty and 11.5 towing fifth wheel, might have to change mind about trading.

 

Just ran 400 miles with a 3,000lb trailer with the cruise control locked at 65 mph, got 15.2mpg. However, I only have 3k miles on the truck. I hope the mpg will improve with mileage.
I do not expect this truck to get the MPG my stock 2004.5 - 5.9 did.

 

Wonder if 2 wd drive will do any better?

 

I drove 480 miles and took 28 gal average of 75 just rolled 20k. 2008 megacab 2500, auto and 3.73 rear end 4x4, stock tires, s&b intake, and MP-8.

 

I thought this was the 6.7L section......

Anyway, last tank was 17.0 hand calculated.....528.5 miles and 31.086 gallons.
