New wax job and MPG

The airlines learned that removing the paint reduced weight resulting in a substantial fuel savings when applied to an entire fleet over an extended period. Millions of dollars were saved yearly by some of the largest fleets that removed the paint from the planes.

So...... get out the steel wool and start rubbing. Remove that unneeded weight and revel in maximizing thine kilometers per liter or whatever units of measurement your mind can latch on to.
 
The reduced weight does save a substantial amount of fuel, but much of those fuel savings are offset by the man hours required to maintain the aircraft shine.
 
Well..... to get technical, ye likely need to emulate the golf ball.

Rather than smooth sleek surfaces ye may see a mpg or kpl improvement by having thine conveyance possessing a dimpled surface.

If a dimpled ball of golf can travel further with an X amount of propulsive force than a non-dimpled ball it seems to me the dimpled surface conveys aerodynamic properties to maximize how far yer' critter gan go on X amount of motion lotion.

A ball peen hammer may be the ticket to max mileage.

That or a heckuva' fine hail storm.

thou art welcome.
 
0.2 seconds off 1/4 mile is way too much, possibly a quarter of that. The weight you lost washing and waxing would proabably make more difference.

It does however, always feel faster with a shiny ride. It's all in the mind.....
 
Technically the biggest air drag is under the car, the angle between your hood/windshield, between the rear window/trunk, the fender wells, the mirrors, and the verticle surface area of the rear.

Waxing a car will not do much, but when you wax a car you usually wash it first, and when you wash it, you most likely washed your wheels and tires and make the rubber less rough (removed the dirt). It will certain make your bvtt dyno feel stronger and the car being quietter.
 
I always thought the unpainted Deloreans were a little faster than the painted ones, but back then we weren't concerned with MPGs, so the opportunity for comparison is lost...

That is only true if you are going slow enough for laminar flow. If you go fast enough to make the flow turbulant...you want it smooth! I don't want to go through the equations right now to know how fast that would be, but I am sure somebody would.
