CNG Cars, Fequently Asked Questions
With all of the upset going on over in Libya, and the gas prices here in America pushing upwards, there has been a lot of talk lately about CNG cars. We have put together a list of a few commonly asked questions in order to set the record straight and to give those looking into purchasing a CNG car the information that they need before making that decision.
Do CNG Cars mix CNG with gasoline?
No. Compressed Natural Gas is it’s own fuel source that can be pumped into the engine. The engine has the ability to run off of gasoline or natural gas without changing any of the components of the engine. When a CNG car kit is installed, CNG injectors are added to the engine as well as a switch. When the switch is activated, the engine will either recieve gasoline, or compressed natural gas, but the engine never receives a mixture of these two fuels.
Do CNG cars last longer than normal cars?
Yes. If you don’t believe us, contact any airport shuttle service or bus service that has CNG converted vehicles. CNG cars on average last up to 500,000 thousand miles before the engines start having problems. By converting your car over to a CNG vehicle with a kit, you will prolong the engine of the vehilce, thus making your vehicle last much longer. CNG increases the value that you get from the vehicle that you convert as it will definitely pay you back over the long run with a long lasting engine.
How Much Cheaper are CNG cars than regular cars?
Gasoline is on the rise, but the average price for a gallon of CNG is $.74 cents. That is incredibly cheaper than the price of gasoline. The important thing to understand is that CNG vehicles usually have smaller gas tanks than a traditional gasoline car. This means that you will need to fill up more often, but when a car is converted to CNG through the use of a cng car kit, the vehicle can run off of gasoline or CNG at the flip of the switch. This is the best option as you can never have to worry about running out of gas because the vehicle runs off of either form of fuel.
Are CNG Cars safe?
Many people think that CNG cars are much more dangerous due to their aluminum composite tank that is under pressure. The scientific evidence proves otherwise. In fact, CNG cars are much safer than your regular car with a gas tank. If you don’t believe us, watch this.
Do CNG cars see a huge drop in engine performance?
The answer to this question is that it depends on the CNG kit that you install. Some kits are better than others, but the high performing kits only see about a 5% decrease in engine power. This number is so miniscule that you will litereally never notice the difference.
Summary
As you can see, CNG cars are incredible vehicles, and the fact is that any vehicle can be converted into a CNG vehicle. If your state has a strong CNG infrastructure, you can save some serious money when it comes to low fuel costs. Not only will you save money, but your vehicle will run much longer, making the vehicle easily pay for itself in the long run.

What is the requirements for stickers on CNG VEHICLES in Utah????
you mean the actual CNG sticker, or the Clean Air Plate?
I am a commuter and love my CNG bi-fuel car. It really only makes financial sense if you drive more than 50-60 miles per day… which is pretty common nowadays. I have cut my fuel bill by over 60%. I had a lot of questions about EPA and emissions issues, and found some good info on http://www.skycng.com. They do not sell anything. Its a good info site for the CNG community. Check it out.
Biggest problem now seems to be millions of different software designs to make gasoline cars operate with CNG. No two software designs are alike. Company A designs software installed in your car. A couple years later they go out of business. You are stuck with no way to have your vehicle engine tuned or repaired since you, as the consumer, never get a copy of that software design.
