PreFlight Airport Parking, a local airport parking and shuttle company, has converted three of its shuttle buses to propane autogas.

The company first converted three of its Ford E-450 shuttles to propane autogas bi-fuel systems in 2016. Three more of the vehicles, which can use either propane autogas or gasoline, will be converted by early summer.

Notably, the company aims to eventually convert all 14 shuttles used at Sky Harbor International Airport.

“The propane system is much simpler than the CNG system, so our own in-house mechanic can do most of the repair work himself,” says John Walsh, PreFlight market officer. “The price of the fuel was also attractive.”

Avoiding downtime on in-service buses was an important factor to the company in making the switch to propane, both in providing service to its customers and being able to service its vehicles quickly. The company says the amount of time spent repairing complex diesel emissions systems and CNG fuel systems was a constant challenge for its shuttles. Click here to read more via NGT News.
