After the recent fuel price increase, advertisements for fuel saving gadgets have been flooding the newspapers, magazines and radio stations. One type of most frequently advertised fuel saving device are magnets that are attached to the fuel line hose.

There are many fabulous claims made regarding the use of these magnets:

  • Save fuel
  • Boost engine performance
  • More complete burning

…all achieved through some weird process called molecular realignment or similar sounding, technical term that you’ve probably never heard of before. The main question is; Is it for real?

Personally, I find such magnetic fuel saving gadgets to be too good to be true. They’re not even that expensive (around RM150 to RM250 each); why then aren’t they already built into modern cars if they’re really useful?

Why do car manufacturers spend hundreds of millions of dollars in fuel efficiency R&D if a piece of magnet clamped onto the fuel line can already provide up to 35% savings in fuel consumption?

Can magnets really affect the molecular structure of fuel to the point of producing a more efficient burning rate?

If you’re skeptical, you’re not alone. Most of the so-called benefits of these magnetic fuel saving gadgets are pushed into the public by the businesses that sell them. There is absolutely no scientific proof that magnetic fields from a device measuring mere inches long can have a positive effect on fuel consumption.

I’m no engineer and I’m merely relating to this topic as someone who has some basic understanding of physics. If you really want to hear it from a real engineer, the you might find this well written article on fuel saving magnets interesting.

What’s your take on these fuel saving magnet gadgets? I’d love to hear your comments.

    If it’s true, perhaps the Toyota Vios and Honda City models must have these magnets on them since these cars are famous for fuel efficiency… 😛

    Heh… it’s Jul 2009 now, and the prices of fuel has come down by heaps all over the world except for Europe. It’s a better time now…even so it’s good to take the bicycle out for some exercise during the summer period.
