Alliance AutoGas used the bi-fuel Prins VSI system to convert the 20 Ford Crown Victorias, two Chevrolet 2500s, one Ford E-250 and one GMC 2500. The project was supported by the Southeast Propane Autogas Development Program.
Additionally, Alliance AutoGas founding partner Blossman Gas installed a 500-gallon autogas fueling station in Spotsylvania County, and the company is also the propane supplier. The county school system has a 10,000-gallon autogas tank at its vehicle service center, which accommodates the refueling of five Blue Bird school buses that run exclusively on propane.
Spotsylvania County officials say they are saving $1.88 per gallon on propane compared to gasoline. The county will save approximately $70,000 in fuel costs annually by running the 24 vehicles on autogas.
Craig Greenlaw, director of fleet services for Spotsylvania County, says the return-on-investment time for the parts and labor of additional autogas conversions is between two and two and a half years.
‘I would tell any fleet interested in transitioning its fleet from gasoline, if you want a proven technology that reduces emissions and fuel costs, then propane autogas will be a great fuel for you,’ he adds.
