how to save petrol

Since the above issue has become the talk of the town, I took the alternative way to save petrol by using a device called "I-charge". It is quite recent in the market (7 Months) and I believe it will be a hot-stuff sometime in the near future. I have tried the device for more than a month and I can feel the difference in terms of performance and consumption of fuel. I would suggest to whoever is interested in it, please do email me. Thank you
