Clean and Green fuel
Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs and lead or benzene pollutants are eliminated.
Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil. Intervals between oil changes for CNG vehicles are dramatically extended depending on how the vehicle is used.
CNG has an octane rating of 127 and has a slight efficiency advantage over petrol.
Mixes evenly in air
Being a gaseous fuel, CNG mixes easily and evenly in the air.
Low operational cost
The operational cost of vehicles running on CNG, as compared to those running on other fuels, is significantly low.
