Switching between CNG and Petrol

[pwuser148455336011]

Salam, I am new and got my first car ( Mehran 1998 ) running on CNG and Petrol. The guy sold me this car told me that I can drive on CNG normally but sometimes it is necessary to drive on Petrol, in this regard I have some questions I know experienced guys can give me better advice.

1) How much time(km) should I drive on CNG and switch back to Petrol to get Mehran's best life?
2) What is the proper way to switch between CNG and Petrol?

Your detailed answers can help me out.

Thanks.

Brother I am no expert but it will be better if you convert from CNG to petrol at night before parking so in the morning car will not give any trouble in starting do this regularly .But if CNG is not must i will recommend you to drive it on petrol in order for engine to last long

for the second part attach a photo of the switch I will guide you how to switch easily
