F uel economy is one of the key misleading indicators when it comes to costing out a school bus, particularly those that are fueled by alternative fuels or gasoline. While gasoline costs per gallon typically are lower than those of clean-diesel, gasoline is less efficient compared to diesel. On average, a clean-diesel school bus can travel about 510 miles on a tank of diesel vs. only 270 miles on gasoline, based on the same standard-sized fuel tanks. Newer engines, like the Detroit™ DD5™ and DD8™ diesel engines, show an additional three percent increase in fuel efficiency. This difference in range and fuel economy quickly mitigates the cost difference between gasoline and diesel fuel.
Let’s look at that on paper.
As you can see, even though clean-diesel costs more than gasoline per gallon, it outperforms other fuel types in operating range and overall costs, based on how efficient the fuel is. Diesel always has been and remains the most fuel-efficient engine (due to more BTUs), provid- ing nearly 90 percent better fuel economy and a longer operating range than any other similar- sized gasoline, propane or compressed natural gas (CNG) engines. Plus, new technologies and innovations, like the Detroit DD5 engine can help you achieve even greater fuel economy and lower fuel costs down the road.
