I can't see how magnets could be used to 'condition the fuel' if there was enough effect on the particles to pull them into alignment (as some of these wonder things suggest) surely cars would suffer huge amounts of fuels starvation and pressure spoting from fuels passing close to Hi ouput electrics, like the start solenoid, alternator or starter motor etc.

Also i have to agree about the a-b-a thing. If you add something on the B test and nothing changes, ITS NOT HAVING AN EFFECT. if it did change from a-b but stayed the same b-a then it was a purely placebic change like an improvement in your base driving style.
