CNG Car Care Guide: Engine Fitness and Fuel Savings
If you have a car that runs on CNG (Compressed Natural Gas), it needs some extra care compared to gas or diesel cars.
CNG burns differently and can make parts wear out faster.
To keep your car happy, start it on gas, then switch to CNG after a short drive, and switch back before you stop.
Get your car checked regularly, change the air filter, spark plugs and oil.
Use the right kind of oil for CNG engines, and don't forget to change your CNG filters.
Following these tips helps your car run smoothly and last longer.
CNG vehicles require specific maintenance due to how the fuel burns.
Start the car on petrol, then switch to CNG after 1 km; switch back to petrol before stopping.
Regular servicing includes annual CNG kit inspections and periodic hydro-testing of the cylinder.
Maintaining air filters and spark plugs is crucial for engine performance.
Use the right engine oil and change CNG filters regularly.
