Frequently Asked Questions

Q: Can I convert my existing gasoline powered vehicle to propane or CNG fuel?

A: Unfortunately, No. In California existing vehicles cannot be converted. Only new vehicles can be converted, prior to delivery to the end user.

Q: How much does CNG cost and where can I buy it?

A: visit for accurate pricing and locations

Q: What type of fuel mileage does a CNG vehicle get?

A: CNG vehicles achieve the equivalent mileage of a gasoline engine. For example, if a 2012 transit-connect  gets EPA-estimated 21 city/27hwy/23combined MPG, you can expect the same fuel mileage from CNG.

Q: Can I convert my diesel engine to propane or CNG? Do you offer propane or CNG injection?

A: We do not offer these types of systems, they are not CARB approved, therefore not legal for sale in California

Q: Are there incentives to purchase alternative fuel and/or hybrid vehicles?

A: Yes. California Energy Commission and AQMD’s have offered incentives for alternative fuel vehicles. These are typically offered on a first-come first-served basis, until funding is exhausted. Currently there is an opportunity with SCAQMD, the deadline is Sept 28,2012 to submit applications.
Hybrid funding is available through the California HVIP program. Visit for more information on this program.

Q: What type of range can I expect with a CNG vehicle:

A: It depends. With commercial vehicles we can add fuel tanks for extended range. This will depend on the body configuration of the vehicle, but typically we us a minimum 24GGE tank on medium-duty vehicles. For practicality, use 22 gallons X expected fuel mileage to calculate your range.

Q: How is CNG measured?

A: Typically, natural gas is measured in cubic feet. However, however for motor vehicles it is measured in “GGE”. GGE means Gasoline Gallon Equivalent. 24GGE = 24 gallons gasoline equivalent
