Does riding with the tailgate down really save on gas?

Come on, this topic has been worn out for years and it has been proven that the tail gate needs to be up when not toting a large load. Why do you think they installed the tail gate on the truck to begin with if it wasn't supposed to be up most of the time? It positively does not save gas by being in the down position, and all you are doing is inviting an accident and getting it torn off or badly damaged.

No. There was an article a while back that trucks get better mileage with the tailgate up. The design of a truck is made to keep a pocket of air in the box to push the flow of air over it. When the tailgate is down, that pocket goes away and the airflow over the tuck is disturbed. That causes worse mileage.

My tailgate stays up unless hauling something that needs it down.

here's the patent:

http://www.google.com/patents/US4573730

"Tonneau covers enclosing the rearward portion of the pickup box to a range of approximately 40 to 60% of the total length of the pickup box provide a greater reduction of aerodynamic drag coefficient than obtained with a tonneau cover enclosing the full length of the pickup box."

The guys on Mythbusters did a show about this. They found closing the tail gate gave the best mileage.

I have bought a cover for my Chevrolet Silverado 1500 with an 8 feet long bed. I always keep records of all my cars/trucks, if my mpg goes up, I will post it here.

Driving in the natural,with tail and head wind affecting my vehicles along with a few really calm days keeps me from worrying about a very few mpgs.that may be gained or lossed by a truck tailgate position.

I don't think anyone has control of initial air forces when traveling to or fro in the natural environment,this planet anyway,wind tunnels are beneficial but stationary,plus time is always on the move with it's pecular forces affecting vehicles in motion(watch a balloon rise)when released,yey some don't LOL!

Year ago when i was traveling back and forth to LA I did that and I actually got maybe a mile or two better per tank full than per gallon. But my tailgate got more pitted. So after that excursion tail gate went up.

anyone remember that study where they tested a special bed cover that only covered half the bed? It did better than a full bed cover or none at all.

Hello bobbysgirl3013. I just have to use KansasGunman's post, "This topic has been beat like a rented mule over the years." He is right as are the other GBs that have posted. Vehicles of all types are tested in a wind tunnel to obtain the lowest possible co-efficient of drag. In the case of any pickup, it is with the tailgate in the upright position. That said, there has been an aftermarket flood of products (e.g. nets, etc.) which purportedly increase fuel economy. From all that I've read this isn't true.

I will bring up something a bit off topic, but important. If you drive with the tailgate down, you are extending your vehicle length and protruding beyond the bumper. A driver may not see the tailgate is down and actually collide with the grill and/or hood. This is especially true at night. I'm not sure of the legalities of doing this or if an accident ensues who would be found to be at fault, but you can see the danger of it.

"No it doesn't, it actually increases fuel consumption. Check out mythbusters, they have an entire episode where they tested this myth. "

The quote above is true, contrary to common belief.

BY having a bed toolbox and removing the entire tail-gate,shedding a few lbs.I have noticed a very slight savings on adverage mileage,more at city use(slower speeds).

Don't open up this subject again. It has already been proven without a shawdow of doubt that having the tail gate down DOES NOT save gas.

Your question is too broad as the aerodynamics of each model truck is different. Some will do better, others worse.

Might save YOU gas if you are RIDING with someone else :)
But really, I dont think there is a measurable difference,
