Amidst the continuously increasing prices of petrol and diesel and uncertainties of EV infrastructure, CNG cars are the best option. They save fuel and are also considered better for the environment. But many owners are troubled by the question whether it is better to run their CNG car completely on gas or should they switch to petrol sometimes.

What do auto experts say on this and should a CNG car be run on petrol from time to time? We will discuss this very thing in this article. First of all let us know the nature of CNG, after that we will talk further.

What is CNG?

CNG is a dry fuel, which does not provide as much lubrication to the engine as petrol. Running only on CNG for a long time can affect the fuel pump, injectors and other parts. Therefore maintaining balance is important for long life and smooth performance of the engine. CNG cars are mostly bi-fuel systems, that is, they can run on both fuels. Most models start a cold engine on petrol, then switch to CNG once it warms up.

Why is petrol necessary?

According to experts, parts of the petrol system should not be left completely idle. The fuel pump needs petrol to stay cool and lubricated. If the petrol tank is almost empty, the pump may overheat, which can be costly to repair. Similarly, petrol injectors get clogged when not used for a long time, which can cause difficulty in starting or irregular performance of the engine.

Do not leave tank empty

Always keep at least 25 percent fuel in the petrol tank. Drive 10-15 kilometers in petrol mode once a week. This keeps the injectors clean and the entire system remains healthy. If on a long drive, switch to petrol 500 meters before the destination. Drive the entire drive on petrol at least once a month, so that the engine gets a proper cleanup. This makes cold start easier and increases the life of the engine. Sometimes the problem of long queues or running out of gas at CNG stations also makes petrol a backup.

CNG has many benefits. Lower expenses, better mileage and less pollution. But the high temperature and dryness of CNG can put additional pressure on the valve seats. Occasional use of petrol balances this effect. Vehicles with factory-fitted CNG kits already have this system in mind.

Bonus Tip: If you are driving a CNG car then follow some additional tips. Always install CNG-specific spark plugs, get regular servicing done and get the cylinder hydro tested on time. Avoid unauthorized mechanics. With the right habits, a CNG car will not only be economical but will also remain reliable for a long time.
