There is also less wear and tear in engines as CNG burns completely, which also helps in saving the expensive costs of part replacements, oil changes, tune-ups, etc. It is also observed that the life of lubricating oils is also increased, as CNG does not contaminate and dilute the crankcase oil.
Over the past one year, there has been a spurt in the price of CNG, led primarily by the hike in the prevalent natural gas price; factors such as increase in blending cost and depreciation of the Indian Rupee also contributed to multiple price hikes.
