Here you go, they help explain all the quackery;
K&J Magnetics - Fuel Magnets

Describe to me how a fixed thing like rotations per minute changes?
Should not happen with a lock up torque converter

Cause tucking in behind the semi will "pull" your vehicle along. If you get close enough you could theoretically take your hand off the wheel and foot off the throttle. Do not try this at home. When you can lessen your wind drag by 40% safely then something's working. http://www.treehugger.com/cars/draft...s-it-work.html

Reading that, they don't sound too sure of it themselves, but of course if someone wants to buy something you can make there is no reason not to, haha. To my understanding though, the nature of hydrocarbons such as gasoline renders them essentially "non-polar," which is why they separate from water (which is polar, meaning that each molecule has basically a positive and negative end). To me it doesn't make any sense... Is there anyone that can direct me otherwise?

If you do a lot of highway driving then you might consider an overdrive unit, they used to add on behind the transmission. Back when I hauled campers over the road the unit was built by Doug Nash Overdrives. This seems to be the main one now. It is switchable, and looks to change the gearing 25-28%. You can get it as an over or under.
Gear Vendors under/overdrive transmissions the most awarded auxiliary transmissions.

regular maintenance first, if your behind on that get that done. Next thing is psi in the tires. I ignore the manufacturers ratings on the car and go 5 pounds less than what it says on the side of the tire. Second is intake system upgrades. Exhaust is next. If you have a pickup truck i would do a cold air intake and a chip at the very least. Diesels will make big gains with a tuner module alone.

Running 75 psi on a 10 ply 16" tire on something like a Ford ranger would be a bit much when it's empty. the amount of air pressure always depends on the weight it carries, so I dont feel like a Cookie cutter answer like 5 psi less than the tire is rated for to be an adequate answer. Not trying to start anything here but I've done 95% of my own tire repairs and been a tire tech for 4 years so I know a few things about tires.

1996 C70 Straight Truck, with a 366 motor, five speed split gears, dump bed, Pfft, be lucky to get 10 miles per gallon.

Load em heavy as hell when your driving that brute down the road

What you did Ted was lowered your RPM a few hundred.

I always look for a tractor trailer to draft behind . I use a 04 GMC Sierra 1500 to go back and forth from the house to the shop(84 mile round trip) truck is all stock, gets 20/22mpg if you keep it at 65mph, runs around 1800rpm. If i draft behind a tractor trailer i can drop my rpm to 1550 and still keep it at 65mph.

I have a 2004 Dodge Ram 1500 Laramie 4x4 with a 5.9 Magnum HEMI V8 and I get 14.6 MPG. The 2007 Ford F-150 4x2 with a 5.4 Triton V8 that I had prior would get excellent gas mileage for a truck - anywhere from 22 to 25 MPG. I DO NOT suggest tailgating Semi's, however I do like it when I get behind them on the highway at a reasonable distance. You can really see a difference!

just install a flux capacitor, they work great.

google hydro xi. and hydrogen generator. easy to build and they work. easy to get 25 % increase in mileage. Water for gas is another site.
