Re: M-zone fuel saver magnets
For my sins, I do actualy have a degree (admitedly 2:2) in chemistry, so I think my opinion may be valid.
Octane is a boring 8 Carbon straight chain, with only hydrogens attched to it. Essentially it has no particular charge centres, and the electron cloud can be thought of as evenly, randomly dispersed, i.e. there are no particular +ve bits or -VE bits. For a magnet to have an effect, it would only do anything on a net local/overall charge.
If my A level physics holds up, a charged particle passing through a mag field of this nature, would tend to spiral/cork screw anyway, so hardly becoming a nice linear arrangement.
Even if it did have an effect, say on some of the chemical additives which may have slight +ve and -ve local charge centres, the instant the fluid has passed out of the field of the magnet, entropy takes effect and would restore the fluid to a highly disordered system, which is more energetically stable.
You can get most molecules to respond to mag fields, in fact there is an entire branch of chemistry involved with it called Nuclear Magnetic Resonance. It is used to identify molecules from resonances to applied mag fields, which give off fingerprint traces. However the mag fields have to be huge, 10-20T (Can stop analogue watch hands and pace makers at 5 metres), and typically at liquid helium temperatures. Not to mention big, a small NMR machine is ford transit sized.
These fuel line mounted magnets are neither powerful nor cold, especially in an engine bay. The magnetic field in the alternator or starter is probably going to give more effect!!
To sum up, if it has any effect at all, the instant the fluid has passed the mag field, any effect would disappear.
