Straight Talk About CNG - Are CNG vehicles safe?

If you have concerns about CNG vehicle safety, listen to an industry expert explain how CNG vehicles are safer than their gasoline and diesel counterparts. Learn about federal safety standards, the rigorous testing CNG tanks must undergo and why they are stronger than anything else on the vehicle.

Why when I look up cng first thing that pops up is exploding cars

[@Kwazii_Life]

If they're so safe why does everyone have to get out of the car while filling up? That should tell you something, not only that but every 3 years you have to get a new tank...

What about long-term usage on wear & tear on engine components???

Thanks for the question. We recommend contacting a truck dealership to get questions answered on engine performance.

I am no expert on CNG, but I do have quite a bit of knowledge about engines. I would say that in some ways running on CNG would be better for longevity than running on gasoline because natural gas burns a lot cleaner than gasoline, so there won't be the issues with carbon buildup that gasoline engines have. The oil would stay a lot cleaner for this reason too. Also, since CNG is a gas rather than a liquid, it won't wash the engine oil off the cylinder walls like gasoline can, and it also can not dilute the oil like gasoline can. Eliminating carbon deposits, cylinder wash, and oil dilution as well as keeping the oil cleaner are certainly benefits for longevity. As for potential longevity disadvantages, I can't think of any but I would suggest doing your own research. People say that the gasoline lubricates the engine's parts such as valves and rings, but it actually has the complete opposite effect by washing the oil off of the engine's parts.

I had a Honda Civic that ran 200k miles with cng and no problem.

@@diego_charles I have a 2008 CNG civic with 320k miles. I have become concerned with the tank integrity over the years so I stand pretty far away from it when I fill up. Considering the thing takes only $14 to fill up it simply cannot be beat in terms of economy

[@diego_charles]

@@lm7bird680 here in my country, you have to do an anual inspection and a tank integrity test each 5 years. If something abnormal is detected the tank is replaced. The gas tanks here have expiration date of 20 years.

Were to get cng stations

[@richbagley8190]

Locate the nearest cng station

They talk alot about CNG not being as flammable as gasoline or diesel. That is true, but gasoline and diesel is not under high pressure and CNG is. A new high pressure thank is probably safe, but what happens when the parts age? Lets say you drive in the rust belt are when the tank and other fuel system components are exposed to elements and hostile environment. How safe are these old tanks then? An old gasoline tank might start leaking, but when a CNG tank fails, it can do so with a big bang, costing you your life. They need to come up with a way to store gas in a non-pressurized form before these gas cars can be deemed safe.

Thank you for the comment. NGV America has additional tank safety info. Here's a link: www.ngvamerica.org/resource-center/?resource_type=safety-documents

[@softwarepole]

this is why tank have expire date, and need to be controlled annually (or once in two year, depending on country laws). So before it might come to the point that old material could pose a risk, it is replaced.

[@ramonruegg8653]

In switzerland there is a inspection cycle of the Gas tank.

[@bernardedwards417]

In The Caribbean there are multiple cases of cng thanks exploding

[@bernardedwards417]

Also some complain about low performance when using cng

[@sassygirl7722]

If you gotta get out of your car and everyone else in the car too kids, pets spouse to get gas ...something outta tell you NO! I JUST HEARD ABOUT THESE CARS TODAY AND WATCHED A CAR EXPLODE , SEVERE DAMAGE. Kept watching more about them. Say No!! It can and will cost you to get one, could even be your life and those you love. Very dangerous and designed to kill

[@bruceevennett6972]

It's like driving in a bomb with no timer

Open Keystone Pipes and MAGA Again. CNG is like driving a motorcycle. Only one accident, and bye bye 👋 wonderful world 🌎
