assuming the magnets are easy to install, you can do ABA testing (see link) rather simply with the magnets off and on and off again (or vice versa). It isn't perfect, because the sample size is very low and it isn't a double blind test (the observer effects the result), but it is better than nothing.

check average mpg, with EVERYTHING else being held equal (or an honest attempt anyway) over a fixed course.

choose points x and y on your course, warm up the car well.

choose a speed for the test, say 50mph here.

wait for outside temp to stabilize and traffic to be gone.

test A:
remove magnets.
set cruise control @50,
reset the mpguino trip exactly at point x
cruise maintains 50mph
note mpg at exactly point y and record.

test B:
install magnets (and do nothing else except return to your starting point).
set cruise control @50,
reset the mpguino trip exactly at point x
cruise maintains 50mph
note mpg at exactly point y and record.

test C:
remove magnets (and do nothing else except return to your starting point).
set cruise control @50,
reset the mpguino trip exactly at point x
cruise maintains 50mph
note mpg at exactly point y and record.


report all results here.

if test A and C are not consistent, then the test is probably not valid.

if test B is not different then the magnets didn't do anything.

dcb, Thanks I'm going to take off magnets on maxima and see if milage drops, then I can start from base number. If it drops then I will try on altima since I have something that will do the same thing as the mpguino on that car. I can reset the milage meter anytime I want.

hondo434, i believe you are sincere in you're belief that these magnets really do work and they increased you're mileage and made the oil dirty and chunky. i believe you in the sense that i think you honestly think it is true.

the problem is we all know for fact that magnets do not alter fuel economy, or cause oil to darken, or get chunks in it. that's why some people were poking fun, but once they realised you are not just bs'ing then the fun stops and we are trying to edjucate and help you to understand that no magnet can do what you believe they are doing.

it absolutely has to be some other cause. the epa (environmental protection agency) has thoroughly tested all sorts of supposed fuel saving devices, including different kinds of magnets that are supposedly designed to increase fuel economy. and the epa has thoroughly busted the magnet myth. on top of that, there has been plenty of independant tests by people like you and me using dyno's and very controlled conditions to also bust these magnet fuel saving devices. to put it simply, they just do not work.

are you framiliar with experimenter's bias? someone else can explain it better then i.

how can we convene to you that they are junk so you change you're mind?
