Signs of a CNG Leak:

Smell of gas: If you smell gas inside or outside the car, it could mean there’s a leak.
Hissing sound: A light or loud hissing noise near the gas kit or tank may be a leak.
Less mileage or power: If your car is using more gas or not running smoothly, check for leaks.
Warning light: Some cars show a light on the dashboard if there’s a problem with the gas system.

How to Check for a Leak (Step-by-Step):

Park in an open space and turn off the car.
Look at the gas tank valve and the pipe connections.
Spray soapy water on the parts. If you see bubbles, there is a leak.
Never use fire to check a gas leak.

Important: If you think there’s a leak, don’t fix it yourself. Go to a trusted CNG mechanic right away.

How to Prevent Leaks:

Check your gas system every 6 months.
Fill gas only from trusted pumps.
Change old or damaged pipes and parts on time.
Keep the gas kit clean and dry.

Interview with CNG Mechanic: What Car Owners Do Wrong

Q: What is the biggest mistake car owners make?

A: “Most people ignore the gas smell. They think it’s normal. But even a small leak is very risky. Another mistake is not checking the gas system regularly.”

Q: How often should they check the CNG system?

A: “At least every 6 months. And every 15,000 km, clean or change the filters and check the parts that control gas flow.”

Q: What about people who get kits fitted at unknown shops?

A: “That’s risky. Many places don’t follow safety rules. The gas kit might not be safe and the car company may stop free repair services.”

Q: Any safety tips for drivers?

Don’t start the car on gas when the engine is cold. Use petrol for the first few minutes.
Don’t fill too much gas.
Always turn off the gas tank before getting the car fixed.

“You wouldn’t ignore a petrol leak, so don’t ignore a gas leak either,” says Rakesh.

Does Installing a CNG Kit Cancel Your Car’s Free Repairs?

Many people ask if fitting a CNG kit will stop their car company from free repair services. Here’s the answer.

What Car Companies Say:

If you buy a car that already comes with a CNG kit from the company, your warranty stays safe. But if you add a CNG kit from outside, the company may stop free repairs for the engine or gears.

What You Can Do:

Only use RTO-approved gas kits.
Get the kit fitted from an official fitting center.
Keep the bill and certificate of fitting with you.

Tip: Talk to your car company before fitting a CNG kit. Some allow outside kits if you get them from approved places.

How to Improve CNG Mileage in City Driving

City roads are full of traffic, signals, and slow-moving cars. This can use up more gas. But with a few simple tips, you can save fuel.

Smart Driving Tips:

Drive slowly and smoothly. Don’t press the accelerator too hard.
Keep a steady speed. Best mileage comes at 40–60 km/h.
Slow down using the engine. Don’t press the clutch or go in neutral too much.

Simple Car Care Tips:

Check tire air once a week.
Clean the air filter often.
Keep spark plugs clean – this helps gas burn better.

Other Tips:

Remove extra weight from your car.
Turn off the engine if stopping for over 30 seconds.
Use map apps to choose faster, less crowded roads.

Even small changes like turning off the AC in traffic can help save fuel.

Conclusion

CNG cars are great for saving money and protecting the environment. But safety and care are very important. You must check for gas leaks, avoid common mistakes, and follow smart driving tips. Also, talk to your car company before fitting a gas kit to avoid losing your warranty. When in doubt, always visit a trusted mechanic.
