Many people on this forum suggest wrong suggestions. They don't talk on fact and figures and misguide others. They usually say "Sub tu kartay hain kia bura hai ismain". Every car looks perfect when it is new but it starts to loose its life on CNG. My car owns the agency Tomasto, Lovato and BRC Pakistan. He himself suggest not to install CNG on markx, CL7 or CL9 and many other cars. There are many other people who even convert there prado and surf on CNG. But that is not a wise decision. Many people over here don't know the complete features of cars. They just go on looks and speed.
