the reason for this lpg obsession is let me first ask sure lpg is not more monopolistic than gasoline. you can even see tests done on the internet that causes your car to burn and explode faster than petrol lpg. However, it is necessary to install the lpg system in a good company (master important) and you will not have any problems after having the necessary checks and maintenance of the lpg system periodically. I have been using lpg vehicles for years and thank God I have not encountered any problems.
