How to prove that "fuel-saving" pills are fraud?

I got in a dispute in a forum about these magic "fuel saving pills" - mpg-caps from FFi (fuel freedom international)
I think there was such discussion here some time ago, but can't find anything :(
googling does reveal what is expevted, tho nothing 100% condemning for this particular "trademark", only that there is an open case (ie still investigating) in Florida.
So anyone with better success in finding arguements?

The best source for debunking of this particular kind of bullshit is probably http://www.fuelsaving.info/.

Their page on mpg-caps in particular: http://www.fuelsaving.info/ffi.htm

Of course, if you present this to someone who actually believes in such technologies, there is a high likelihood that you will be inundated in conspiracy theories; have a look at http://www.fuelsaving.info/conspiracy.htm if you wish to be prepared.
 
ps: whats the thing with all the spam emails I get from mexican chemists are tablets in the u.s incredibly expensive ?
 
Practically it's easy: get those pills and drive 2x 200 km, one round without and one with those pills. Compare the consumption and you're done.

Not necessarily. There are numerous possible confounding variables (driving style, weather, tyre pressure, amount of passengers/baggage, all of which can have a substantial effect on fuel usage) that need to be accounted for in such an exercise.

Also, since these particular pills are supposed to work by creating a coating on the inside of the engine, their effect (if they indeed have any effect at all, which I doubt) could very well last for a while even if you stop using them; this could hide their effect if you try this exercise on a car that has received any of these pills lately.
 
You don't - you "develop" you own that work "even better! New and Improved" and sell them to the dumbasses who buy the others. This is a company that had marketing materials that said their stuff has "positively charged electrons" for pity sake.
 
Arjan: I know, but if it's the same route, that should suffice for a rough estimate. Otherwise you can rinse and repeat until you have enough data for a healthy statistic.
