Can a Private Car Pass the Annual Inspection After Converting from Gasoline to CNG?
2 Answers
Private cars can pass the annual inspection after converting from gasoline to CNG. Below is an extended introduction: 1. Modification Method: If it is necessary to relocate the CNG cylinder due to certain reasons, it is entirely possible. The service life of the cylinder is 15 years. For relocation, a secondary inspection must be conducted at a cylinder testing station. After obtaining a new Vehicle Cylinder Usage Registration Certificate, the cylinder can be relocated and used normally in a new car. 2. Insurance Coverage: After the "gasoline to CNG" conversion, as long as the issue is not caused by the newly added gas-related equipment, the insurance company will cover it. At the same time, it is recommended that car owners who have modified their vehicles notify their insurance company to update the newly added equipment and purchase an "Additional Equipment Loss Endorsement" to ensure claim eligibility.
My sedan was converted from gasoline to natural gas last year and passed the annual inspection in one go. The key is to choose a certified conversion workshop—don’t go for cheap options from small garages. After the conversion, you must go to the DMV to update the vehicle registration. They’ll take new photos and issue an updated license. Remember to bring the conversion certificate and the gas cylinder inspection report, as these are checked during the annual inspection. A friend of mine failed because the gas cylinder mounting bracket wasn’t properly installed. Inspection stations are very strict about gas pipelines now, so it’s best to check for leaks beforehand. Oh, and when the gas cylinder’s validity expires, it must be re-inspected—otherwise, it won’t pass.
