Salam All,
LPG is costly as compare to CNG but the point is now you dont have CNG, you have just Petrol and LPG..
And LPG is cheaper than petrol and more efficient.
There is one point u have to know that 1kg of LPG = 2 ltrs. of LPG.
LPG Price = 65 per ltr.
Petrol price = 102 per ltr.
The point is LPG and Petrol have almost same milage....
If anybdy want to convert his car, feel free to contact...
