“Complete nonsense”

written by HonestOne on 01/09/2011

Right, here we go, let us investigate the claims of magnetic fuel savers and their basis in science shall we:

1. Fuel is 'aligned' by the magnets
No, it just isn't. hydrocarbon fuels (all of them) are non-magnetic and non-conductive, which limits a magnet's influence on them to the diamagnetic effect, which is weak to the point of being unobservable. Even IF this force was strong enough to produce detectable effects (which it isn't) it would only introduce a tendancy for the fuel molecules to flow away from the magnets, not align them in any way.

2. 'Hydrocarbon chains are broken down'
Magnets cannot affect the molecular structure of hydrocarbon fuels, or any non-magnetic and non-conductive material for that matter.

3. Magnetic fuel systems were used by the RAF in WW2.
I actually happen to be a pilot in the RAF and I can tell you that this claim is absolute rubbish. Do you not think if we'd figured this one out all those years ago we'd just have stopped bothering to use it? As it happens we kinda like fuel economy as it means we have to ship less of it around. The British Armed Forces do not use this device and never have, that is a fact.

And now even assuming that the above is true:

4. Shorter hydrocarbons burn with more energy.
Yes, they do, VERY VERY VERY slightly more energy. Nothing even close to a percentage point here. This would produce no observable effect.

5. Fuel burns faster
Great, and that will see significant LOSSES in power and economy unless the ignition timing is adjusted to compensate, and you'll be handing your local tuning garage about £400 for an engine remap to achieve that.

6. Fuel burns more completely
Any car made in the last 20 years will burn over 98% (higher in most cases) of fuel that enters the cylinders, so even with magical perfect burning efficiency how is that ever going to produce more than 2% efficiency increase?

So to conclude, the science that these things are based on is pure fiction, none of it stands up to even basic scientific scrutiny. what's more, despite contacting many manufacturers, including this one (they did not respond) requesting the studies they so love to quote, I have yet to see a shred of data. Strangely, there are reams of data from many reputable car and review bodies that have tested these products, and they all seem to share my opinion. Please do not waste your money on this, it is a scam and i think it's disgraceful that these con-artists aren't behind bars.
