Facts About Fuels

Diesel is Clean

  • Based on EPA regulated emissions, diesel is comparable to or even cleaner than other fuel types.
  • Diesel emissions are 90% cleaner than they were in 2006.
  • Thomas Built Buses exceed EPA and greenhouse gas standards for:
    • Particulate Matter (a carcinogen)
    • Nitrogen Oxide (causes acid rain)
    • Carbon Monoxide (greenhouse gas)
    • Non-Methane Hydrocarbon (produces smog)
  • 60 of today’s Saf-T-Liner® C2 school buses produce fewer combined emissions than one school bus from 2002.
  • Diesel has the lowest carbon footprint over the operational life of a school bus.

Diesel is Cost-Effective

  • Diesel is the most fuel-efficient engine type.
  • Diesel fuel outperforms other fuels in operating range and fuel economy.
  • Diesel buses have better resale value. The large diesel resale market doesn’t exist for gasoline, propane or CNG buses.
  • When you look at all the factors (fuel cost, fuel economy, bus purchase price, operating range, maintenance, resale value) diesel buses offer the lowest Total Cost of Ownership.

Diesel is Proven

  • Diesel engines are built for the long haul and can last 15 to 20 years or more. They almost never need to be replaced during the life of a school bus, which can significantly cut your costs.
  • Many alternative fuel engines aren’t built for medium-duty use or have to be upfitted, adding to costs.

Diesel is Innovative

  • Diesel has a long history of success, from the invention of the diesel engine in 1893 all the way to the ultra-efficient Detroit™ DD5™ and DD8™.
  • Thomas Built Buses can thank their relationship with Daimler AG for many innovations. Daimler is the parent company of Mercedes-Benz, which launched the first diesel car in 1936.
  • Today’s diesel engines are so advanced that they can go up to 45,000 miles* before needing oil and fuel filter changes.
    * Or either 18 months or 1500 hours, whichever comes first.
  • New diesel engines such as the Detroit™ DD5™ and DD8™ come equipped with industry-leading telematics systems not available anywhere else that measure engine diagnostics, lowering maintenance costs and increasing uptime.
  • More exciting diesel innovations are just over the horizon.
  • Low emissions. Best-in-class fuel efficiency. A low total cost of ownership.
  • Power. Proven performance. And reliability.
