Since turning to propane, Colonial Parking has cut fuel costs by 32 percent and bus maintenance costs by 28.4 percent.

The airport shuttle operation applied for a grant through the state of Pennsylvania, which covered half of the incremental cost of the shuttles, although according to Groden, even without the funding, the vehicles would have paid for themselves very quickly.

With their near-constant use, the company’s 3-year old shuttles “already have 140,000 miles on them, and have had no issues other than routine maintenance,” Groden said. “Our mechanic is astonished at how clean the oil is when our propane vehicles are due for service, and our drivers say that the propane vehicles function better than our gasoline vehicles, especially during cold winter months.”

The buses’ ROUSH CleanTech fuel system uses propane liquid injection, which “helps eliminate cold-start issues while…
