Question

Does adding a taneau cover to your pick up increase your gas mileage?

Answer 1

No, despite common misconceptions to the contrary, it does not.

Answer 2

it does a little bit but not really noticeable they proved it on mythbusters

Answer 3

the only way to know for sure is to  measure efficiency aerodynamics of the vehicle with and without the cover. the cover reduces wind resistance therefore improving gas mileage. i imagine your gas mileage improvement will be minimal.

Answer 4

trucks are designed to be driven without any type of cover and are aerodynamically designed to get the best mileage without a cover on it. Same holds true with putting the tailgate down. It doesn't really increase mileage.

Answer 5

Not really.  It does make the truck more aerodynamic so in theory you would pick up a little bit in the fuel milage department, but the added weight of a taneau cover would negate any aerodynamic effects.
