CNG is compressed natural gas, a fossil fuel that is more abundant than oil. It is cheaper than petrol (about 80 cents an equivalent litre, versus $1.90 for petrol); and is considered to be cleaner than diesel.
What does converting your car to run on CNG entail?
A CNG conversion kit is fitted, with prices starting from around $3,000. The kit consists of one or more gas cylinders (usually placed in the boot), pipings leading from the cylinder to the engine, valves and regulators, and a refuelling intake.
Where do CNG cars refuel?
On Jurong Island or in Johor Baru. But a new pump in Singapore Petroleum Company's Jalan Buroh station will open next month, and another belonging to Smart Energy in Mandai Link will open in February. One other station in Serangoon North will follow within nine months or so.
What if the car runs out of CNG before you find a station?
The car will still be able to run on petrol. It will stall only if it is completely empty of both fuels.
Is there any downside to switching to CNG?
Conversion may void the car's warranty, and could result in a slight drop in power. More expensive conversion kits can address the latter.
Is it safe?
CNG is less flammable than petrol. Cylinders have release valves in case pressure builds up; and gas is lighter than air and will dissipate fairly quickly.
