Will A CNG Conversion Void My Warranty?

There's a reason this is #1 on our FAQs page; we get this question all the time. Many dealerships/salemen and shops like to tell/intimidate people that CNG conversions will void your warranty. This is a bold and broad statement, since performing warranty work on a blown headlight has absolutely nothing to do with the aftermarket installation of a bi-fuel CNG system.
Here are the facts: Drivers are protected by something called the "Magnuson-Moss Warranty Act of 1975". This says a manufacturer cannot void the warranty just because of your aftermarket parts. If your transmission fails under warranty and you have a CNG conversion, then your transmission is still under warranty. This act goes on to clarify that the burden of proof is with the manufacturer or dealer if there is any argument over what caused the failure. Example: Your engine throws a rod under warranty and you have a bi-fuel CNG conversion kit. Well, if the CNG system was not properly installed by a licensed installer, then maybe the dealer has a legitimate argument... however the burden is on the dealer to PROVE that the CNG kit (whether installed properly or not) was the direct cause of the engine failure.
The reality is that when properly installed by our trained technicians your sequential CNG conversion will not void your warranty. Even an extensive search on the internet will not find any legitimate cases where a CNG car conversion has resulted in engine failure or warranty issues. Lots of people like to talk about it, but the fact is CNG conversions are widely accepted around the world as aftermarket parts and modifications. As long as you have a professional and qualified installer then you will be all good.

What Are Some Advantages Of Converting My Vehicle To CNG?

In Oklahoma, CNG is less than ½ the cost of gasoline, result is saving 50-70% of the current gasoline budget, using our own natural resources and minimizing dependency on foreign oil, and at the same time helping the environment by burning CNG that is fourteen times cleaner than gasoline. Maintenance and oil changes are also extended 4-5 times due to the cleaner operation.

Can The CNG System Be Removed/Transferred To Another Vehicle?

Yes, our system can be removed at any time without affecting the gasoline system. Usually the only time this might be done is when the vehicle owner wants to sell the vehicle and feels he/she could not recover the conversion cost with the sale or in cases where the owner would like to reinstall the system on any new vehicle. Our conversion is a totally standalone system, meaning it is separate and does not use nor require any portion of the original vehicle components.  We utilize a fully programmable ECM (onboard computer) and this technology allows programming for any 4, 6, 8 or 10 cylinder engine.

Will Using CNG Be Harmful To My Engine?

No, the opposite is the case. The usage of CNG can extend the life of the engine. This is due to the clean combustion of CNG and the fact that no carbon is generated during combustion. The engine components and oil are not subject to the contamination produced by using gasoline or diesel as fuel.

CNG stands for Compressed Natural Gas. It is an alternative way to power most types of vehicles, instead of gasoline. Because of large reserves of natural gas that are present in the United States, the popularity of CNG vehicles is growing quickly since the cost is low, and the source of the fuel is not subject to politics elsewhere in the world.

This can be done at any time during operation; however most times it is not used. The reason being, all CNG-gasoline switching is done automatically and seamlessly by the CNG computer. All the driver has to do is drive and enjoy the savings. Your vehicle can switch from CNG to gasoline while driving 70 mph and you will never know unless you see the gauge light change colors.

Do You Have To Remove My Vehicle's Gasoline Tank?

No, the CNG system uses its own storage tank, usually mounted in the cargo area or underneath the vehicle, depending on available space and driver-owner preference.

Will Mileage Or Performance Be Affected?

Natural Gas is rated at 130 octane and gasoline is rated at 85-90 octane. With our conversion technology allowing precise distribution giving each cylinder the same amount of energy in Natural Gas as gasoline, the performance will remain the same at 5% (+/-). Most drivers can expect up to a 20% increase in fuel mileage with the higher quality CNG providing more saving.

Can I Fill My CNG Vehicle At Home?

Yes. Homeowners with an existing natural gas supply line may be able to purchase a home refueling system designed to fill their vehicle. Gas from the same supply line that feeds your house is compressed and pumped into your vehicle.  Most pumps have automatic shutoff, so you do not have to stay with your vehicle while it is fueling.  Simply connect the nozzel to your vehicle, start it, and walk away.  As CNG is becoming more popular in the US, more options for home fueling are becoming available.  Contact us for more information.
