A diesel Ford 4000 tractor was chosen for the first trial since it was only being used for the same job each day. With a bedding machine attached it chopped and blew straw into the cattle yards. Fuel usage was recorded for 13 days prior to fitting the Ring Magnet and then recorded for 24 days with the magnet installed. Time taken to do the job each day was logged as is shown in the following table:-

The magnet was fitted on the fuel line on 31st March 2004.

Date Days Litres Hours Lts/day Hrs/day

29/04/04 11 50.0 13.6 4.54 1.24
Average after magnet fitted 4.29 1.17
Savings with magnet 13.7% 14.6%

The magnet was then put on a New Holland TM165 tractor which was being used for cutting grass during silage making. Accurate figures were not recorded however the farmer estimated that he was saving £6 per day on diesel.

Another magnet was fitted to a Renault Savana 1.9 Turbo Diesel car belonging to the farmers wife who is a vet in general Practice. The results were as follows:-

MPG
Before Magnet was fitted 32.6
After Magnet was fitted 42.2
An increase of 29%

Finally a second hand Range Rover was purchased by the farmer's brother in London where it had been used mainly for the school trip and shopping. On the way home on the motorway the farmer could get no more than 60mph out of the vehicle and there was considerable exhaust smoke. The magnet was then put onto the Range Rover which within a short while was capable of 80mph with greatly reduced smoke. He is reluctant to give the magnet back to his brother's wife.
