A small gismo installed under the bonnet turns the petrol into gas and 99 % of the fuel gets converted to energy and exhaust gasses emit nothing harmful.
Gas mileage goes up more than half and virtually no damage is done to the environment....
Why do our car manafactures and goverments not make fitting these devices compulsory,or is that the giant oil corporations want us to buy more oil...!
I think we the public are being well and truly screwed by both.....:(
