Magnets

Birdwell L&K · 16-08-2007, 20:53

Just thought I would tell everyone about the 2 high strength magnets I have put on my Octavia II 2.0 tdi pd with the dsg gearbox. Before I installed them I used to average 40mpg knocking about, now I average 48mpg knocking about and 58mpg on a long run.

The magnets are installed just after the fuel filter, I did this after I heard audi are experimentig with magnetic fuel lines.

isnt this like the magnets on your home water pipes to remove limescale?

ednmra · 17-08-2007, 13:03

Interesting but it would be nice to see some double blind testing done on this

- if consistent, it should be possible to pinpoint the science behind it.

Aspman · 17-08-2007, 13:25

Here is link to some tested in the US

"Gas-Saving" Products: Fact or Fuelishness?

Essentially they say - Fuel magnets = pants

Another US one

ABC12.com: Gas magnets: How well do they work?

No effect.

And another

CNN.com - No shortcuts to saving money on gas - Aug 8, 2006

Fuel saving company shut down and getting sued

And another

Gas-saving devices mostly a scam - MSN Money

The science is pants anyway. Carbon compounds in petrol aren't magnetic so the fuel magnet would do bugger all.

I would guess that your new found fuel economy is down to your new awareness of the fuel economy of your car. You are most likely lighter on the gas than you were before.

If it sounds too good to be true, it is.

ednmra · 17-08-2007, 20:26

Being a cynic I'm inclined to agree. I wonder what magnets are supposed to do to control basically non magnetic calcium salts etc in water pipes, or for that matter how magnetic bracelets are supposed to cure various medical ailments.

Double blind is the answer and using such testing on large samples tends to make a lot of pseudo science fall apart.

dstev2000 · 17-08-2007, 20:46

If they are that good then why don't ALL manufacturers stick them on their cars? especially in this day and age of eco-mentalism.

The last time I checked Diesel isn't magnetic

There have been lots of tests on this and you may as well stick a pink scrunchy around the fuel line, it will do the same thing!

Sorry Birdwell L&K but they probably don't do anything to your fuel

Take them off and use them on your fridge.

Oli · 18-08-2007, 09:41

Ah the ol' magnetic mpg increase placebo, don't believe any of it myself.

djgritt · 18-08-2007, 10:27

It doesnt work

I work in Industrial Combustion (Power Generation, Industrial Gas/Oil Boilers, Process) and this isnt utilised atall, due to it not working.

There are companies selling "Magnetic Fuel Economiser Boxes" etc, but its all a gimmick

You dont notice anything on a Burner using anywhere from 400-1400 l/hr of Oil (Diesel, Residuals, Light etc), so you definitely wont notice it on a car that gets nowhere near that sort of fuel usage!

ednmra · 18-08-2007, 11:32

This reminds me of a friend who is a retired GP and forensic medicine expert, and is, sadly, riddled with MS.

His wife wears magnetic bracelets for her arthritis.
When asked why, considering her husband's knowledge and problems, she says "Well, nothing else works either!"

It wouldn't be so bad if she hadn't paid about £100 for the junk.

bahnstormer vrs · 18-08-2007, 14:16

The must do something!

I had a Bioflow/Ecoflow magnet thingy on the fuel line of my Diesel Omega for more than 2 years/40,000 miles. It always ran smoothly but I must honestly say there was no noticeable difference to performance or fuel consumption

BUT when I took the magnet off (prior to selling the car) on the first start up the engine was coughing/spluttering/misfiring for a couple of minutes before settling down to run normally.

QED?

Probably all the metal cr*p sticking to the inside of the pipes making its way through and out of the system.
So, yes, they must do something

METAL BITS!!?? How do they get past the fuel filter?

anonymouse · 18-08-2007, 15:11

You'll still get microscopic powder, strong enough magnets and this will accumulate

s3akr · 18-08-2007, 21:49

laughed my butt off at this thread. Next they'll be telling us to put rocks in the fuel tank to allow cars to run smoothly on poor grade fuels!!

ednmra · 19-08-2007, 08:41

Rocks in tank definitely improve petrol costs - you can't get so much fuel in.

**mannyo** · 19-08-2007, 08:50

Going back to the original posters figures, I get 58MPG on long runs, and nearly 50MPG on shorter runs, on my STANDARD untouched 2.0TDI 140BHP. There have been lots of independant tests that show these devices do nothing, except line the bank accounts of the companies making the claims.

How many miles have you done in your car? As my MPG is pants compared to that. On long runs I get 48mpg!!

I've only done 7k miles!

fireftrm · 26-08-2007, 21:55

As tot eh removal caused misfire for a time, if the magnet s were like the ones I have seen in economy 'devices' then they are in a tube located in the fuel line - you had to put ehm inline like a filter, so removal would mean soem air in the line. They are pants - total pants. They are sold on the 'magnetise the fuel to make it burn better' pitch, which can't and won't work at all. The fuel is not metal and so can't be affected by the magnets and the whole thing is a scam. Most likley is that the engine is loosening up and the driver is being more carefula s they are deliberately looking for a fule saving.

The most economical addition tot he car would be a two inch thick wooden block under the accelerator, or some simply driver habit realignment.

Lummox · 26-08-2007, 22:14

Even if it did attract particlesin the fuel line what would happen then?

Well slowly the pipe where the magnet is would get smaller and cause a blockage, but hey that would save fuel.

Having said that I do have an eco magnet thing myself. It sits on my toolbox keeping important bits of paper still.
