has this actually been proved to work? your talking about those E-boxes that sort of magnetise the fuel?
there have been some warnings on tv and studies about these magnets in my country. a university study ran 2 exact same engines for dozens of hours in a lab, one with magnets and another without. the result was that both had basically used the same amount of fuel, but the one with magnets had even used verry slightly more. but it was within the error margin i think.
in reality they usually do have a positive effect on the FE of those that use them, but that is mostly a placebo effect. and also that the manual of those magnets said that for it to work you needed to drive non-agressively, accelerate slowly and drive in high gears...
