I am curious why in a vehicle like your Hyundai i30 you install LPG or Gas system. Is it worth risking the safety of the passenger inside or it is total safety? Will you save money and how many time is needed to get back the investment?

Because of the prices we pay for petrol ( gasoline.) Prices for LPG now where I drive is 50 % cheaper than the petrol prices and the car needs only around 1 liter per 100km more LPG then the petrol. For examle I need 7-8L per 100km petrol and LPG 8-9L per 100km. That is combined fuel consumption. Investment for instaling the gas system was back for less then a year because I drive around 20 000km per year. I paid aroud 450 euros for instaling the system. I thik that instaling a LPG system in car is very safty, the botle where the LPG is stored is indestructible.
