Has anyone noticed any difference in gas mileage by covering the bed with a tonneau cover etc.

I'm now driving 82 miles round trip to work and am looking for anything to improve my gas mileage. (I should have bought those pills I saw advertised years ago allowing you to run your vehicle on water!!)

 

My dad owns a "other" and he just put his hard cover on last summer, he noticed at least 2 mpgs with it.

 

Yes, absolutely, I now average approx 20 mpg with my A.R.E LS11 hard cover. Before the cover I would average approx 17.5 mpg.

 

Thanks for the info. It sounds like a cover would pay for itself and look good too.

 

I get 2 to 3 MPG better with my A.R.E Hard Cover than I did without it!!!Lariat#1

Hello All,

I am getting 2-3 MPG better with my
Sportmaster cover.
It also seems to handle better in wind and it is quieter with the windows rolled down on the highway.
All this and they look great too!

I am having a real hard time understanding just how a hard cover could increase your mileage by 2-3 mpg, or roughly 10-20%! I would belive 0.2 to 0.3 mpg.

When you drive your truck, where does the engergy from the fuel go? Several places.

1) Engine & transmission friction. It takes power to spin the motor and gears, alternator, etc... Adding a cover does not change the amount of power required to spin the motor and the accessories.

2) Rolling resitance - Pushing four tires and 4,500 pounds down the road takes power. A hard cover does not reduce the tire friction (increasing tire pressure would), and adds weight to the truck.

3) Overcoming wind resistance - The total amount of Aerodynamic drag has two components - Frontal Area and Drag Coefficient. The hard cover does not reduce your frontal area at all.

I acknowledge that the hard cover will slighlty improve the drag coefficient. But enought to increase your gas mileage by 10% to 20%?

No way.

You might be surprised at how much wind the tailgate grabs. Everyone I have ever talked to said that by simply putting the gate down will add at least 1 mpg (while weakening the sides of the bed).

A hard cover just might lessen the drag on the truck to give the truck 1-2 mpg easily.

I can justify the tailgate down for at least 2mpg on my F-150. Try it yourself, you'll notice it!

 

I have a cover (and love it), and the MPG has gone up a little. But if you do 12,000 miles per year, the difference between 18MPG and 20MPG is 66 gallons per year. Don't plan on paying off your cover that way anytime soon.
