We all know that fuel prices are spiralling and that we all want to save money if possible. This is a top quality, but reasonably priced way to doing just that.

What it's made of

It is a Neodymium Iron Boron (NdFeB) magnetic assembly. Each half is made up of a yellow plastic shell in which a neodymium N38H grade block and a mild steel plate is fitted. The mild steel plate has the effect of focusing the magnetism downwards into whatever it is attached to. Each block has reads 3500 Gauss in the centre of the plastic shell. The neodymium block has then been coated to protect it because of its' iron content which, as we all know, rusts if exposed to wet or damp conditions.

We have used Neodymium Iron Boron (NdFeB) because it is the strongest magnetic material available capable of lifting approximately 1000 times its own weight by magnetism alone. Furthermore NdFeB magnets are permanent which means that the magnetism is never lost providing that it is not exposed to temperatures greater than 80°c. Most NdFeB magnets start to demagnetise at this temperature and demagnetisation is total at 120°c. However, this unit has an H grade magnet which means that it operates at higher temperatures and does not start to demagnetise until 120°c. Interestingly, a NdFeB magnet loses about 2% of its’ magnetic strength in the first 20 years of being magnetised but after this it does not lose any. This does rely on the protective coating remaining intact since rust will also cause a loss of magnetic strength. This means that the Fuel Miser will almost certainly outlast your current vehicle and probably your next one too!

Fit it without any mechanic skills

All you need to know is where your fuel line or injector pipe is! Please note, we cannot assist with this.

It's really easy to fit too. Simply place the two halves around the fuel line/injector pipe, then, using the cable tie provided, secure the two halves together.

How and why it works

This is not an easy question to answer. However, there have been studies carried out on the effect of magnets on gas and flames and it is, therefore, the same principle for vehicle fuels. The studies were reported in the Physica B journal in January 1996 (volume 216 pages 403-405) by Nobuko Wakayama and Masaaki Sugie who were (and may still be) at the National Institute of Materials and Chemical Research in Japan.

In essence this research found that adding a magnet to gas did not change the chemical composition of the gas in any way, however, it did find that the gas became magnetised and that, because oxygen is paramagnetic (it is attracted to a magnetic field), there is a better oxygen-gas mix and this means that the gas is burnt more efficiently and at a higher temperature.

When applied to a liquid fuel the same affect occurs. The liquid fuel becomes magnetised so the molecules will align themselves within the magnetic field. When the fuel is mixed with air the magnetism within the fuel means that there is more oxygen mixed into the fuel than would otherwise have been the case. When the fuel is then ignited it will burn more efficiently and slightly hotter. The more efficient burn means that there are less unburnt hydrocarbons and carbon monoxide in the exhaust fumes. The net result of this is that your vehicle will go further on the same amount of fuel and you will save money. In addition, there will be less combustion build up because of the more efficient burn and, therefore, your engine should also have a longer life.

What happens once it's installed

Once the unit is fitted, all fuel passing the magnet will be magnetised and, as soon as that fuel starts to be burnt, you will benefit. However, to establish exactly how much fuel you are saving you will need to monitor fuel consumption for at least 1000 miles/1500 kilometres.

Special Considerations

  • The units can be used on ANY engine be it car, van, boat, outboard, large goods vehicle, bus, motorbike, scooter, large plant, etc. With bigger engines, more than one pair of units may be required.
  • It is suitable for vehicles with fuel injectors, turbochargers or normally aspirated and with or without catalytic converters.
  • Diesel engines with mechanical injectors require one pair of units on EACH injector line.
  • As a rule of thumb, you will need one unit for every 1200cc. So for a 2 litre vehicle we would recommend two units.
  • On large diesel engines (including lorries, boats, combine harvesters etc) you will need one Fuel Miser on each injector line.
  • We have satisfied customers who are reporting up to 29% fuel savings although our testing has produced results in the region of 5-8%.
  • Other suppliers claim that the magnets improve the performance of the vehicle, we have not found this in our testing on a reasonably modern car but some improvement may be seen on older vehicles.
  • The magnets should be kept a reasonable distance (30cm) from any computer on your vehicle.
  • If you replace your vehicle, simply cut the cable tie and remove the Fuel Miser units and then, using a new cable tie available from all DIY/Hardware retailers, fix it to your new vehicle.
