My 2011 Milage

[4506dave]

Took a little road trip over the last few days and here are my results.

Distance Travelled
844.4 km
524.71 miles

Fuel Used
154.5 liters
40 US gal
33.99 IMP gal

Fuel Economy hand Calculated
18.3 L/100
12.85 mpg (us)
15.44 mpg (imp)

Truck computer numbers
17.4 L/100
16.23 mpg (US)... I think

Truck has 9550 kms on it. Cruise control set at 140 km/h, temps ranged from -15 to +3 celsius, 1500 to 2000 feet elevation. Truck is bone stock with a roll n lock bed cover. Hour meter had 9 hours on it for the trip, some idling and a little city stop and go traffic, but mostly hi way. Do these numbers seem on par with what most are getting with these trucks. Its a far cry from the very high 20's I got with my 2009 when driven nice (110 km/h), and 20 average at this speed, mind you it was way far from stock.
Just a little FYI

As far as breaking in the engine goes...you've not really even got it warmed up...

I did not check your math or the conversion from metric but what you reported seems on par considering you were operating in very cold temps.

My truck runs just a hair over 17mpg (US) in "normal" temps on empty hiway trips at 70mph. That seems to be pretty normal if you sort out the "extreme" reports that get posted.

As far as the truck's computer, , , , , they all lie. Some more than others. I think the computers are OK but the fuel flow sensors are not calibrated very accuratly. I have found my truck says it uses about 1.5 gallons (US) less than it really does and that throws the computer off. I have also found that if I stop filling the tank when the pump kicks off the computer will be closer on gallons used. If I "top off" the tank then that extra will not be measured by the computer.

Thanks for your report!!

12.85 and 16.43 is pretty far off.... Truck calc'd mileage is usually within 10%.

I went to a Canadian Govt website and plugged in my km and liters used and this is was it gave me for numbers. I think it's still pretty low considering my 09 was getting a little better. The dealer reports that all trucks they have sold are getting 20ish mpg hand calculated and they can't and don't know where to look as fuel Milage is not a warranty item and any time spent will cost me shop labour to figure out

I just got back from vegas I live in bakersfield ca. My truck has Stage 2 AFE intake 35" tires 4" lift cc lb 3:31gears I can almost hit 500 miles with one tank on the freeway empty. This trip I towed a 40 foot toyhauler weekend worrior tandom axle loaded trailor alone about 16k to the nascar races in vegas I only got 260 to the tank. I kept it in cruz control 65mph almost the hole way unless I seen a highway patrol that puts me at just over 7 miles per gallon. Does that sound right?

I average 10.5 with a 34' 8,500 lbs TT so far.

That is a nice rig shirtaday!! I can see the wedge shaped front helps on fuel too.

I pull a 19 foot toy hauler that is 5900 lbs empty and usually around 7500 when we pull it. My trailer is almost 12 feet tall with square front and I get around 9.5mpg pulling it at hiway speeds 65-70.

I can also see joe 6.7's gear ratio making a lot of differance in mpg. He runs the 3.31 gears and is around the 20mpg mark empty but that ratio and 35 inch tires hurt him pulling. I have the 3.55 gear set and do around 17 empty but better loaded mpg than he does. I have the 34 inch factory tires too.

The amazing thing I like to read is where joe 6.7 says he pulls a 16k lb. trailer at hiway speed on cruise control!! These trucks have some big balls don't they?? It shouldn't be this easy to pull loads!!!! Gotta love that!!!!

[ShirtaDay.com]

Yeah... I'm running 35" MT's with 3.31 ratio. I figure I drive unloaded Mon - Fri and pull the TT trailer maybe 1/3 of the weekends and the boat another 1/3 of the weekends and spend the remaining 1/3 empty.

The V-nose is supposed to help. Would be curious to know how much exactly...

No worries 4506dave I have been consistently getting better mileage the more miles get on the truck.

the first few tanks I got around 12mpg and now I'm getting around 15mpg, hopefully it keeps going up.

Has anyone else seen this where their mileage increases with break in?
