Propane autogas school buses are a common sight in communities across the U.S. Hear what these school officials have to say about their propane autogas bus fleets.
Lowest total cost-of-ownership. Infrastructure that fits the budget. A complete selection of quieter, safe buses from every leading brand. Propane autogas buses check all the boxes for school transportation officials.
Propane autogas is consistently less expensive than diesel. But transportation directors interested in long-term savings need to think beyond the pump. This is where propane autogas edges out diesel — by avoiding the typical “hidden costs” over a vehicle's lifetime.
FUEL — Historically, the price of propane falls between the price of crude oil and natural gas. As a result, propane consistently costs less than diesel, even as fuel prices fluctuate.
FLUIDS — Diesel buses need more oil by volume compared with propane autogas, increasing preventative maintenance costs. In cold temperatures, diesel vehicles also require fuel conditioners (also known as “anti-gelling agents”) to prevent clogging of fuel filters and lines.
FILTERS — Fluids and filters are added expenses with today's low-emissions diesel technology. To meet emissions requirements, diesel particulate filters (DPF) must also be cleaned periodically, causing extra downtime and added maintenance expense.
REPAIRS — Even with a disciplined maintenance program in place, transportation directors may find that expensive repairs and replacement parts for diesel buses drain funds one problem at a time. Injectors, exhaust gas recirculation valves and coolers, turbochargers, dirty after coolers, and irregular closed crankcase filters are just a few of the additional expenses associated with diesel. The likelihood of downtime for repairs is even greater considering the complexity after-treatment systems add to a diesel engine.
Diesel buses are designed for minimal idling, which should not exceed five minutes at a time. Excessive idling only piles on the maintenance and repairs for diesel buses — not to mention the downtime for every fix.
Propane autogas providers specialize in helping fleets choose the right refueling option for their operation. The best refueling option depends on a fleet's size, routes, budget, and facilities. Propane autogas infrastructure uses the same pump and motor to a handle a growing number of tanks and dispensers — allowing infrastructure to grow as a school adds buses.
