As for ionizing the molecules....that means you've stripped off electrons. It would take a heck of a magnetic field (and you'd have a grounding problem with the metal line) to do this. Where do the free electrons go? And you take vitamins/veggies to reduce these same types of free radicals in your body--should you drop a multi-vitamin in your gas tank and some broccoli in your oil to reduce these? Let me know how your veggie car that works for you.
Just so that your scientifically accurate ionizing isn't always caused by a magnetic field. For example, when you dissolve table salt (NaCl) into water it seperates creating positive Na ions and neg. Cl ions. These are not harmful to you nor is the water magnetic. The pos. and neg. cancel each other out. I'm not saying that this will help/hurt a vehicles performance in any way. Just trying to keep things in the right context.

In my opinion, free radicles, though not entirely the same thing as ions, could possibly be benificial if it could be used in conjection with gasoline. The mechanism that you refer to about free radicles harming your body is referred to as the autoxidation mechanism. That is "oxidation requiring Oxygen and no other reactant. If we could in some way oxygenate our gasoline by a way of forcing it to bond some oxygens, it could possible be more powerful and cleaner burning.
I'm saying that just because free radicles in your body are bad for you, does not mean that they are bad for your car.
I've had way too many chem. classes in the last couple of years. Next year, I'm on to Quantitative Analysis, Biochem, and Physical Chem. Then I'm done! <img src="/forums/images/graemlins/smile.gif" alt="" /> 2 Degrees in 4 years.
