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.

How Much MPG Does a School Bus Get? Admittedly, the average school bus's fuel economy is what you'd expect of a bus—not great. According to the Alternative Fuels Data Center, school buses get an average fuel economy of just 6.02 miles per gallon (MPG).
If a school bus had an 80-gallon tank and operated with a fuel economy of about 6 miles per gallon, it could travel about 480 miles. According to the U.S. Department of Energy, the average school bus travels 12,000 miles per year4.
According to the U.S. Department of Energy, the average school bus travels 12,000 miles per year 4. At the average school bus mpg, that means a single school bus would use about 1,993 gallons of fuel annually.
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.
There is no standard size tank. It could be anywhere from less than 30 gallons usable to over 200 gallons usable. It all depends upon what the original purchaser ordered from the factory.
Diesel. Among other types of fuel transport vehicles use, diesel fuel is a popular choice for those working with larger-capacity vehicles such as buses, vans, trucks, and boats.
Although this car might reach a maximum speed of 50 MPH on a level grade compared to a 60–75 MPH maximum for a city bus, its 0–25 MPH acceleration rates are superior to almost all older city buses, and many modern ones.
Some alternatively fueled engines like propane or gasoline may need to be replaced two to three times during the normal lifecycle of a school bus. Clean-diesel engines, on the other hand, are built to last 15-20 years. The difference in engine life lies in how engines are built.
Buses help conserve natural resourcesThe production of fuels for planes, such as kerosene and jet fuel, requires huge inputs of energy and causes a lot of pollution. In contrast, producing diesel fuel for buses takes much less energy and results in far less air pollution.
BEBs are powered by battery packs that run an electric motor to turn the wheels, the same as battery-powered electric cars. The batteries are recharged by plug-in chargers using electricity from the transmission grid. Since they do not use gasoline or diesel, BEBs do not produce tailpipe pollution.
