Can my car run on Natural Gas?
Mileage results vary among vehicles based on several factors but if you select a high quality CNG conversion system from CNG United and if the CNG conversion system is installed correctly, then your mileage results when running on CNG may remain completely unchanged compared to your mileage results when running on gasoline or diesel. In a few cases, a slight decrease in mileage may result but even in such cases, the many benefits of running on much lower cost CNG justify having CNG United install a high quality CNG conversion system in your vehicle.
What are ways to ensure efficient fuel mileage when running on CNG after the CNG conversion system is installed?
There are many things that can be done to For example;
- Service the vehicle a regularly scheduled intervals.
- Make sure to use a quality CNG conversion system from CNG United so that you can be certain that your CNG conversion system will be properly matched to your engine according to its liter size and horse power.
- Properly tune and calibrate the vehicle after your CNG conversion.
Does CNG affect my vehicle performance?
If your vehicle is in good running condition before one of our high quality CNG conversion systems is installed and if our CNG conversion system is installed properly, preferably by a certified CNG United installation technician, then you should experience the same level of performance on CNG as you do now on gasoline. In some cases when operating a CNG powered vehicle up a long inclining roadway, you may on occasion find yourself pressing more heavily on the gas pedal to maintain the same highway speed. The technical reason for this is because CNG has slightly less kinetic energy than Petroleum Fuel (Gasoline). Except for such limited occasions, you will find your vehicle performs just as well running on CNG as it does running on gas or diesel, except that you will be paying a lot less at the pump to purchase a gallon of CNG!
What is involved in the installation of a CNG conversion system in my vehicle?
The installation of a CNG conversion system in your vehicle consists of placing and securing brackets that support the CNG gas tanks, placing and securing the CNG tanks in the brackets, configuring and running high pressure CNG hose lines along the vehicle chassis from the CNG tank to the engine compartment, installing various system components under the hood, installing the wiring harness, completing the post-installation checklist and performing vehicle laptop calibration / tuning and testing to ensure optimal post-installation vehicle performance.
Can I install the CNG conversion system myself?
We highly recommend using a Certified CNG United Installation Technician. A certified CNG United installation technician is well trained and very familiar with the handing and installation of our CNG conversion systems, including computerized information systems, hard lines, detailed wiring harnesses, high pressure CNG tanks, and related components. We recommend that our CNG equipment be installed by a highly trained CNG United technician who knows how best to configure our CNG conversion system and related components in your particular vehicle for maximum safety, space savings and performance results.
Will the installation of a CNG conversion system affect the manufacturer’s warranty on my vehicle?
Since each manufacture is different, we encourage you to inquire with your particular vehicle manufacture to be sure.
Where does the CNG fuel tank fit in my vehicle?
The CNG tank is shaped similar to a scuba tank used by a diver to breath oxygen under water. The size of the CNG tank can vary depending on individual customer preferences and vehicle usage patterns / needs. Some CNG tanks may be longer and thinner or shorter with a larger diameter. The placement of a CNG tank in a vehicle is a decision that is typically discussed beforehand by the vehicle owner and the installation technician. After taking into consideration the purpose and utility of the vehicle, in most cases, CNG tanks are placed in the most logical location in vehicles. For example, in a passenger vehicle, the CNG tank is typically placed in the back of the trunk space nearest to the back of the rear passenger seat. In the case of an SUV, the CNG tank is typically installed behind the last row of seating and immediately inside the back entry door/s. In the case of a typical light truck. The CNG tank may be installed in a sideways position directly behind and underneath the rear window in the truck bed. Different CNG tank sizes can also be used to accommodate custom locations for placement of the CNG tanks such as underneath the truck bed where the spare tire is stored, or a long slender CNG tank may be selected for installation along the driveshaft to minimize or eliminate any need to use other available space.
What happens to my original gas tank?
Nothing. Its stays right where it is so that you will have the luxury of owning a “Bi-Fuel” vehicle which means that you will keep your original gas tank so that you can run on gas while also being able to choose to run on much lower low cost CNG whenever you like. A simple press of a button that is installed on your dashboard allows you the convenience to switch to or from CNG or gas / diesel on a moment’s notice.
Can I refill my CNG tank in my vehicle at home?
Yes! You have an option to install a personal use home refueling system that is connected to your home gas line and power source. Home-based fueling systems typically refill CNG tanks at a rate of 1 – 1.2 gas gallon equivalent per hour. Although such home-based systems refill CNG tanks more slowly than more powerful commercial CNG refueling systems, if you don’t need to be able to refill your CNG tanks in the same approximate amount of time that it takes to fill your standard gas tank with gasoline or diesel, then this approach may be for you and can enable you to technically remain “off the grid” which means that you may never need to refuel your vehicle with gas or diesel purchased from a gas station ever again. Since the rate of refueling CNG tanks using home-based refueling systems is not fast enough for some customers, such as small fleet operators that run businesses, there is no need to worry. CNG tanks can be refilled with CNG more quickly by using a slightly larger CNG refueling system.
How long does it take to install a CNG conversion system in a vehicle?
The length of time it takes to install a CNG conversion system in a vehicle depends on the level of experience of the installing technician. Typically, we recommend that you allow two days for our CNG conversion system to be properly and professionally installed in your vehicle. If you have access to a certified installation technician with an experienced helper, the installation of a CNG conversion system can be completed in 1 to 1.5 days.

Diesel Conversion System (Diesel to CNG) Questions
Can I stop using Diesel Fuel completely and just run my vehicle exclusively on Natural Gas?
Not altogether, because in a diesel engine to CNG conversion, you must run the diesel engine on a blend of both Diesel fuel and CNG at the same time. The use of a blend of diesel and CNG is required because diesel fuel contains elements, including a lubricant that your Diesel engine requires to run properly but you can still benefit from the use of CNG along with diesel since CNG is so much lower in cost compared to diesel fuel.
What ratio of CNG to Diesel fuel can I expect?
Many factors need to be considered to accurately answer this question such as the utility of the vehicle, the driving conditions, whether the vehicle is operated under heavy loads/weights, whether the vehicle is used to go down into a deep mine and return with tons of load, etc. Generally speaking, if a 50/50 ratio of diesel to CNG use is great! Ratios of diesel to CNG of as much as 60% – 40% diesel to CNG and even 70% – 30% diesel to CNG have been recorded. Note: The elimination of any more Diesel fuel from the equation above these ratios in favor of using even more CNG than diesel may result in a loss of vehicle performance. Since diesel fuel contains more Kinetic energy than CNG, the ratio of diesel to CNG that is used to run a vehicle matters, particularly when running a vehicle under a heavy load.
CNG Tank Questions
How big is the CNG tank?
CNG tank sizes vary depending on the space available to install the CNG tank as well as the gas gallon equivalent that you choose to have installed which may depend on your driving habits and needed range. In every case, the shape of the CNG tank remains basically similar to a Scuba Diver’s breathing tanks. The CNG tanks can and do vary in terms of diameter and length of the CNG tanks so there are many choices to suit your particular needs.
What’s safer? Gasoline or CNG?
CNG is safer than gasoline on a number of categories / scenarios. Just to name a few: there is no pooling of natural gas under an upside down vehicle unlike gas or diesel, CNG is lighter than air (approximately half the weight of air) so CNG floats up and away when it is released from the CNG tank into the atmosphere. Natural gas requires a perfect mix of oxygen and N.G. and temperature to ignite (1080+ degrees Fahrenheit) whereas the ignition temperature for gasoline is a relatively low temperature range of just 475-536 degrees Fahrenheit.
Is Natural Gas better for my engine?
Yes! Natural gas enters the combustion chamber of your engine in a 120+ Octane gaseous form and generates a much more complete combustion compared to gas or diesel fuel. The more complete combustion of CNG reduces the microscopic charcoal residue that is left behind from partially ignited petroleum fuel (i.e. gas). For this reason, by running on CNG, your spark plugs will perform better and last longer without becoming fouled by a buildup of carbon that results from partially burned gasoline. Even the oil in your vehicle will stay cleaner longer by running on CNG.
