LPG prices keep getting higher. So the price difference between LPG and petrol keeps getting smaller. With the high cost of conversion, the ROI is getting longer. It seems it is now harder to convince other people to convert than it was a few years ago.
It is somewhat similar to what happened between diesel and gas. Years ago, their price difference is big, but not now.
You think that would also happen to LPG, that the price difference between LPG and gas would soon catch up to just a few pesos?
