DIESEL SCHOOL BUS FAQs

Diesel is not only viable; it’s arguably the BEST Choice.

When developing your school bus Fleet game plan, it’s important to keep close consideration of diesel, a fuel that is sometimes unfairly perceived as less environmentally friendly than other options. In reality, diesel has evolved significantly in recent years, thanks to advanced engine technologies and cleaner fuel formulations that have transformed it into a much cleaner energy source.

Cleaner Than Ever Before
The introduction of Ultra-Low Sulfur Diesel (ULSD) and new emission control technologies like Selective Catalytic Reduction (SCR) have dramatically reduced harmful emissions from diesel engines. Modern diesel buses produce a fraction of the pollutants compared to older models, making them an environmentally responsible choice. Diesel exhaust fluid (DEF), used in SCR systems, further helps by converting nitrogen oxides (NOx) into harmless nitrogen and water vapor. As a result, today’s diesel-powered buses meet and even exceed stringent emission standards, offering a cleaner alternative to older diesel technologies.

Cost-Effective and Reliable
Diesel is not just cleaner—it’s also one of the most cost-effective choices for school districts and transportation providers. Diesel engines are known for their durability and long life, reducing the frequency of replacements and major repairs. This reliability directly translates into lower maintenance costs over the lifetime of the bus. Additionally, diesel vehicles have higher fuel efficiency, meaning they can travel further on a single tank, reducing fuel expenses.

Lower Total Cost of Ownership
Diesel technology also offers an advantage when it comes to the total cost of ownership (TCO). Though the initial purchase price may sometimes be higher than alternative fuel options, the long-term savings from lower maintenance, fewer breakdowns, and extended engine life outweigh these upfront costs. Additionally, because diesel fueling infrastructure is already widely available, there’s no need for significant investment in new fueling stations or charging infrastructure, as with some alternative fuels.

The Future of Diesel
As diesel technology continues to evolve, innovations like hybrid diesel systems and renewable diesel fuel are pushing the envelope further in terms of efficiency and environmental impact. Renewable diesel, produced from organic waste products, has the potential to drastically reduce carbon emissions without requiring any modifications to current diesel engines. This means that diesel can remain a viable, future-proof option as emissions standards continue to tighten.

Diesel has come a long way in the last 25 years.

Click each fact to learn more.

1 gallon of diesel has 113% of the energy of one gallon of gasoline.

Diesel engines are built for the long haul. They can go up to 45,000 before needing an oil change and up to 225,000 before needing a filter change.

All engines today have emissions that are well below federal emissions standards.

  • Even though CO2 is not monitored by the EPA, it is still a greenhouse gas. Over the lifetime of the bus, diesel engines emit less CO2 than propane or gasoline engines.
  • All our current engines emit 90% less emissions compared to 2006.

All engines currently meet or exceed EPA emissions regulations.

With further emissions improvements on the horizon, Thomas Built Buses exceeded the EPA greenhouse and gas standards for 2021 in:

  • Particulate Matter
  • Hydrocarbon Emissions
  • Carbon Dioxide Emissions

Based on EPA regulated emissions, diesel is comparable or even cleaner than other fuel types.

Diesel has the lowest carbon monoxide emissions of any type of fuel. It also has the lowest carbon footprint over the operational life of the vehicle.

Alternative fuel engines are not always the cleanest.

EPA regulated emissions, diesel is comparable or even cleaner than other fuel types. Diesel also provides the safest, least combustible, most reliable power.
