Fuel type: Diesel vs. gasoline
The fuel type used in a bus is an important consideration for bus operators and fleet managers, as it affects operating costs and environmental impact. Diesel and gasoline are two common fuel types for buses, each with its own advantages and disadvantages.
Diesel buses typically have better fuel efficiency compared to gasoline buses. A diesel school bus can travel about 510 miles on a tank of diesel, while a gasoline bus can only travel 270 miles on the same-sized tank. Diesel engines also have higher torque and better power efficiency, making them ideal for pulling heavier loads over extended mileage or operating in hilly terrain. Additionally, diesel engines require less fuel to produce the same output as gas engines, as they use a combustion system rather than a spark ignition system. This makes diesel a more cost-efficient option in the long run.
However, diesel engines have higher upkeep needs. They often require a significant parts replacement mid-life and are more sensitive to cold temperatures, which can trigger higher repair rates. Diesel engines also need more fluids to operate, increasing maintenance and operation costs. Additionally, diesel fume exposure can cause negative health effects, especially for vulnerable populations such as young children and the elderly.
Gasoline buses, on the other hand, have lower upfront costs and are easier to maintain. They have higher horsepower, providing greater power for a shorter amount of time. Gas buses also have moderate fuel costs and it is easy to find qualified technicians for repairs.
While diesel buses have traditionally been more common, the number of natural gas and hybrid buses is increasing due to their favourable economics and clean air benefits. Electric buses, in particular, offer low fuel costs and zero-tailpipe emissions, making them the most environmentally friendly option. However, electric buses are typically the most expensive to purchase and take longer to refuel.

Fuel economy and efficiency
The fuel economy and efficiency of a school bus are important considerations for fleet management. Fuel costs represent a significant portion of a school bus fleet's annual operating expenses, so understanding how to accurately estimate total fuel costs is crucial for budgeting and purchasing decisions.
The average miles per gallon (MPG) for a school bus can vary depending on several factors, such as the size and weight of the bus, the type of fuel used, driving conditions, and the age of the bus. Larger buses, such as a typical 36-foot school bus designed to seat around 72 passengers, tend to have lower fuel efficiency compared to smaller buses. Their average MPG is around 6 to 10 miles per gallon, while smaller shuttle buses can achieve 15 to 20 MPG.
The type of fuel used also affects MPG. Most buses run on diesel or biodiesel, which offers better fuel efficiency than gasoline. Diesel engines have higher torque and power efficiency, improving MPG ratings. However, diesel fuel tends to be more expensive, and diesel engines have higher maintenance and repair costs. Newer hybrid buses that use a combination of diesel and electric power can achieve even higher MPG than traditional diesel buses.
Driving conditions also impact MPG. Buses operating in urban areas with frequent stops and starts tend to have lower MPG ratings than those travelling on highways. School buses typically operate in city and suburban areas with frequent stops, which results in lower MPG due to the increased fuel consumption in stop-and-go traffic. Optimising bus routes based on understanding the gas mileage of each bus can help improve fuel efficiency and reduce the need for frequent refuelling.
Improving the fuel economy of school bus fleets offers significant financial savings and environmental benefits. By prioritising fuel efficiency, school districts can reduce fuel costs and emissions, leading to healthier communities and cleaner air. Therefore, it is essential to consider both the upfront costs and the long-term fuel efficiency when managing school bus fleets.

Driving conditions
The type of driving conditions and routes can impact the fuel efficiency of a school bus. Buses that travel on highways tend to have higher fuel efficiency compared to those navigating through urban areas with frequent stops. Understanding the gas mileage of each bus in a fleet can help optimize routes by considering the range and refueling needs. This knowledge can inform strategic decisions about which buses to deploy on longer routes and the types of conditions that may affect fuel efficiency on different routes.
Additionally, the driving style can influence fuel efficiency. Practicing a gentler driving style and taking time to reach destinations can increase fuel savings and enhance the safety and comfort of passengers. Aggressive driving behaviours, such as rapid acceleration and hard braking, can contribute to reduced fuel efficiency. Smooth and controlled driving can optimize fuel usage and improve the overall riding experience.
Weather conditions and road conditions are other factors that can impact fuel efficiency. Adverse weather, such as strong winds, heavy rain, or snow, may increase fuel consumption due to the additional resistance and challenges posed by these conditions. Similarly, road conditions like steep inclines, rough terrain, or congested routes can affect fuel efficiency. These conditions demand more power and torque from the engine, potentially resulting in higher fuel usage.
It is worth noting that while diesel engines generally offer better fuel efficiency than gasoline engines, the choice of fuel type can also influence driving conditions. Diesel engines provide higher torque and better power efficiency, contributing to improved fuel efficiency ratings. However, the use of air conditioning in school buses can significantly reduce fuel economy, so using it sparingly can help maximize efficiency.

Size and weight
The size and weight of a bus are major factors in determining its fuel efficiency. Larger and heavier buses tend to have lower fuel efficiency compared to smaller buses, as they require more fuel to move. For example, a typical school bus, which is larger and heavier than other types of buses, has an average MPG of around 6 to 10 miles per gallon. In contrast, smaller shuttle buses used for short distances have a higher average MPG of 15 to 20 miles per gallon. The size of a school bus is designed to accommodate a large number of passengers, usually ranging from 50 to 90 students. The weight of the bus, combined with the weight of the passengers, can cause the bus to consume more fuel, leading to a lower MPG.
The fuel type used in a bus also affects its MPG. Most buses run on diesel or biodiesel, which generally provides better fuel efficiency than gasoline. Diesel engines have higher torque and better power efficiency, improving their MPG ratings. However, diesel fuel tends to be more expensive, and diesel engines have higher maintenance and repair costs. On the other hand, gasoline costs less per gallon, but it is less efficient, resulting in lower MPG.
Newer hybrid buses that use a combination of diesel and electric power can achieve higher MPG than traditional diesel buses. Additionally, driving conditions and routes impact a bus's MPG. Buses operating in urban areas with frequent stops and starts tend to have lower MPG ratings compared to those travelling on highways. School buses typically operate on city and suburban roads with frequent stops, which results in lower MPG due to the increased fuel consumption in stop-and-go traffic.
The age of the bus can also play a role in fuel efficiency. Older buses may have lower MPG due to engine wear and tear and less advanced technology. Additionally, the specific model and make of the bus can impact its MPG, with some buses being designed for improved fuel efficiency. For instance, a 25-foot high-ceiling Thomas International school bus from the year 2000 can average just under 12 MPG.
By understanding the factors that affect a bus's fuel efficiency, such as its size, weight, fuel type, age, and driving conditions, fleet managers can make informed decisions to optimize fuel costs, reduce emissions, and improve public health. Additionally, route optimization based on the gas mileage of each bus can help improve overall fuel efficiency and reduce the environmental impact of school bus fleets.

However, it is important to note that driving style, weather conditions, and road conditions can influence these figures.
Now, let's discuss the maintenance and repair costs for a school bus:
To optimize maintenance costs, school districts can implement strategies such as reducing the number of backup buses, optimizing routes, and staggering school start times to reuse buses across different educational levels. Additionally, enforcing safe driving practices and regular driver training can help prevent accidents and reduce maintenance expenses while enhancing student safety.
Some specific maintenance and repair costs for a school bus drivetrain with 15,000 miles per year have been estimated in online forums. These include an annual oil change for around $1,000, replacement of two tires for approximately $1,000, and repairs by a mechanic starting at $1,000. Performing repairs oneself can help save money, but the parts and materials still incur costs.
It is worth noting that fuel costs and maintenance expenses are closely linked. By investing in fuel-efficient technologies and engines, such as the Detroit DD5 engine, you can improve fuel economy and reduce overall fuelling costs. Proper maintenance and safe driving practices can also contribute to optimizing fuel efficiency and minimizing fuel expenses. Therefore, when considering the overall costs of operating a school bus, it is essential to factor in both fuel and maintenance aspects to make informed decisions and budget accordingly.
