Anyone ever tried these things for helping fuel economy ? :-/

Oilo de Python...

[Mr Skrunts]

In a word.

No

[Entwood]

Absolute codswallop !!!!

If they were any good... don't you think every manufacturer would have fitted them for years

The only thing they are good for is relieving mugs from their money ...

Sorry ...  :-? :-?

[philhoward]

Spend the money on a pair of flip-flops instead - you'll save more money by having a lighter right foot..

[perfferle]

I have Been hearing about this effect for years. Would be REALLY interesting to follow this thread and see what the experts have to say

[willyboy]

I get the picture

Unfortunately I don't know enough about the internal properties of petrol to comment in detail, but logically, I agree with Entwood that if the technology was proven it would be implemented a lot more widely.

Just read the guys feedback and he"s sold quite a few...

Says 90 day money back guarantee....however later in the listing he states ""In old engines, depending upon the carbon & varnish condition of the system, the extra mpg may be reduced temporarily. In old engines it can even take up to few thousands miles"" I doubt there's many people who will so a few thousand miles in 90 days.

Its like the 20/30 BHP booster ive seen on Ebay for the omega...think the cost was £2.99 so its gotta work yeah  

[willyboy]

LOOL
Not forgetting the
Vauxhall Intake Supercharger Turbo for Calibra Omega  
Also on ebay at £14.95 up to 9 mpg more with it !!!!!!!!!

I did some scientific trials on these many years ago using natural gas and yes, we did see a few percent improvement.......I seem to think they are now used on some large boiler installs.

The problem I have is that a fuel injected engine working on a liquid fuel is going to be very different, by the time the fuel has hit the back of a hot valve and atomised, how much of the magnetism is left.

[Entwood]

Well he claims to use the "neglected" science of magnetohydrodynamics ... those who believe his waffle should read what magnetohydrodynamics is actually all about ...

http://en.wikipedia.org/wiki/Magnetohydrodynamics

which has cock-all to do with magnetizing fluids .. but is actually the study of the conductivity of fluids and the effect that magnetism has on that conductivity....  now as I've not yet seen a fuel system that uses conducted electricity in the fuel delivery system ...........  

As said before.. its a load of b*****ks

This is just a standard MAGNET. Few people in Poland checked “power improvements” and there is no improvement in power or consumption with PG powered cars. Nothing as you would expect. If the engine is running ok, these won’t make any difference.
Mark said about boilers – new heating systems (especially industrial ones) are fitted with these on water and gas line. I must say that it makes a difference. On water lines it helps to dissolve lime and sediments and same thing might help your engine if your petrol line is clogged.
Magnets on gas lines helps (according to heater manufacturers, I don’t know what’s the efficiency without them) to burn it, but this is gas, not liquid. I  have found one of these on the scrap yard and decided to put it in my engine on LPG pipe. Not that I trust these things, but if you want to have an opinion you have to “sleep with your enemy” . This way I can tell “I had it and there is no improvement”. Unfortunately I must say that there is a consumption improvement. Don’t get me wrong – I’m not telling you that it works. Maybe there was something else that happened with my engine, but since that time I have few miles extra.
I am sure it wont give anything when running on petrol.

Your fuel already flows through a magnet - the coil inside the fuel injector!

Now, if this magnet did something magical to the fuel wouldn't the fuel injector reverse it? Or have the same effect anyway?

.. and if it's upstream of the fuel rail on the flexible rubber hose as shown,  the fuel path to the injector is fairly long. Wouldn't any effect of the magnet be undone by the fuel being forced round a fuel rail at high pressure?

For the pennies it would cost manufacturers to fit this at production, and considering that the tiniest fuel or emissions saving is of interest to them these days, if they worked they'd be standard fit.

I have found some tests that show no power improvements. Nevertheless, injector “magnet” wouldn’t be strong enough to do anything. Anyway – if your engine is running fine, you won’t get any more power or less consumption.
I only said that my LPG consumption went down after installing magnet on LPG pipe, while I am sure that doesn’t give anything on petrol pipes. It might be anything – new LPG supply (summer LPG contains more Propane, less Butane), drier air etc. Doesn’t have to be magnet.
Manufacturers are not that optimistic about any improvements. Even if it would be worth a penny, I don’t think they would fit it – would be a special feature for extra expensive cars, like good braking pads, deoilers, turbo charger etc…
Well anyway – don’t think it’s worth to buy it. I got mine for free, but I wouldn’t pay for it
