Does anyone know if you get better gas milage with the tail gate off or on. I work an hour away from home and most of it is highway. I just took off my camper top to reduce some weight and took off the tailgate hoping that will help. Thanks for any help. |

In theory it should reduce some drag and let you run more efficiently.
Your driving speed and other conditions, like tire pressure, surface, and a/c, will all affect it much more I think. Edited by reifidom |

I'm no engineer, but my experience is YES, taking off the tailgate will improve your MPG.
My friend used to have a Mazda b2200 pickup when we were in highschool. When we would go on trips to other towns, we weould always put the tailgate down, and my buddy would swear it would help the aerodynamics by not having that big old "air catch" of a bed. I drove his truck both ways on the highway, and you could definitely tell there was less wind resistence. It's just more aerodynamically sound not to have the tailgate on there. It should give you better aerodynamics and MPG, even if it's only a little something-something. Edited by Zesty |

^Na, just do it and see how it feels....I'll bet there will be significantly less resistence.

I've heard people swear by putting the tailgate down, but I've also heard contradicting aerodynamic studies. I don't know.

There
was a thread on PBN about this. They said there is no difference
because there is an air pocket formed in the bed, so the air just flows
over the bed and tailgate with no resistance.

Just try it on two full tanks of gas and see how many miles the odometer runs before you have to fill. That'll tell with better accuracy.

Ok, but there are allot of variables especially on highway travel. But heck this isnt for national security or anything. Thanks for the help everyone. |

The problem with that, is at one time, he might do more highway driving, and the other he could be doing more stop and go.

I don't agree with the air-pocket theory...if that was true, then why would stuff in your bed fly out?
If the air-pocket was true, then whatever small cans and trash that is in the bed would be in the air pocket, and wouldn't get sucked out. But if you roll with your tailgate up and trash in your bed, it's gonna fly out. So my stoner theory goes against the air-pocket theory. |

If you need a tailgate just get one of those mesh-style ones.

But he doesn't need tailgate, he just wants to know if there is a difference in MPG with it on and off.

I've been towing for many years. Multiple studies have been done by the
gov., vehicle manufactures, and trailer manufactures. Not one of them
says taking your gate off does anything. I don't consider any studies
done by air gate or the net Companies as very valid because they are
trying to sell you something. The reason is there is too much
turbulence coming off the roof. The only things that help are a full
cap and/or a wing on the roof. Theoretically some of the turbulance is
allowed easier escape with no tailgate but the math proved it was so
slight that you would never come close to seeing that as improved gas
mileage. I will dig up some of the articles if you really need them.

He's going to be using it anyway. And about the different driving, that's fine. He's just looking for a yay/nay kind of an answer here. |
