Surprisingly Bad Fuel Economy

Hi Folks,

I have a 2103 Toyota Tacoma V6 4WD (GCWR = 11,100, GVWR = 5450), and I am pulling a Kodiak 221RBSL (Dry 4616, normal kind of load for two people camping, so I am guessing up around 5600lbs - I try not to travel with anything in the tanks). Truck has a rated tow capacity of 6400lbs. I included the GCWR and GVWR as I know that calculating tow capacities is a complex thing .

The truck pulls OK all the way to 70mph, but seems happier around 60. I have a WDH and sway bar so handling is good. What has surprised me is that I am getting slightly less than 10mpg on a run, even less with a strong headwind (not surprising) where it drops to about 8.5mpg.

This seems low to me - I am not sure what I was expecting, but not this.

Any thoughts or comments? Anyone have a comparison of a similar set up?

I am getting the fuel stats from an OBD Reader as well as good old fashioned math. All numbers are US gallons.

Thanks,

Drew.

I was going to make a "Back to the Future" comment about your 2103 Toyota, but I digress.

10 mpg Doesn't seem too terrible actually. Most of the guys I know pulling campers with a gasser get between 7 and 10 regardless of make/model/brand. Going by that, you're at the top of the spectrum. Guys with diesels get a little better, maybe 12 or 13 depending on their setup.

I am actually surprised that a 6-banger does that well. Usually they just don't have the torque that the V-8's do, and thus fuel economy suffers when towing.

cheers

WOW. I get an honest 12.5 with my one ton dually and Cummins, towing a 8100 pounds of trailer.

A smaller trailer towing with a Ford Expedition, we got 5.

I'm guessing you live where it's flat. 10 mpg is real good for a truck that's maxed out on the tow rating. Try towing in the mtns for a while then you'll see 8.5 all the time. Problem with those small trucks is the small gas tank. Not much range when traveling.

I think you're doing fine with a V6. Smaller engines get good mpg running lite, put a load on them and they suck . With my V10 pulling 12 tons, I get 8mpg.

10 MPG sounds good for the amount of power those engines make.

Look at it like this. Your'e moving close to six tons, ten miles down the highway at 60-70mph for the cost of a couple or three cups of coffee.

I'd say you're about right. Unless someone hand calculates, I wouldn't trust it.

Thanks to all for the posts and the examples. I guess the little Taco isn't doing so bad after all. I have been really surprised at how well it tows the trailer from both a power and handling perspective. As one poster mentioned the gas tank is a little one the small side which means frequent stops. Not the end of the world.

Drew.

We only pull a little 2500 lb EggCamper, but I now get better fuel economy pulling it with my small V8 Tundra (14 mpg), than I did when I used my V6 Chevy S-10, (12 - 13 mpg).

I sold off my 2001 6.0L (gas) Chevy 2500HD 4X4 SB since it would only get between 7 to 8 MPG on flat land towing my first 5er. Bought a new 2008 6.7L Cummins/Ram Diesel, now I get between 10 and 12 depending on wind and terrain towing my 5er. These are hand calculated fuel numbers.

V6 needs to rev, higher rpms and more throttle can be worse than having 2 more cylinders with lower rpm and less throttle.

Sounds about normal for a smaller gasser towing.
