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.
The Thomas C2's overall average mileage for the four test segments was 9.2 miles per gallon; competitor product's overall average was 7.6 miles per gallon. Standard Type III SAE test methodology was followed in each of the test segments.
A new propane-powered version of the C2 was introduced in July 2019. The bus uses the Power Solutions Integration Driveforce 8.8 litre LPG engine paired with the Allison 2500 or 2550 PTS transmission. A 70- or 100-gallon fuel tank configuration is available.
Diesel school buses are already the most fuel-efficient in the industry, due to a higher BTU count compared to other fuels, providing better fuel economy and a longer operating range compared to similar-sized gasoline, propane or compressed natural gas (CNG) engines.
The Detroit DD8 is a 7.7L in-line 6-cylinder medium-range engine that boasts a horsepower range of 260-300HP and a torque range of 660–860 foot-pounds for the Saf-T-Liner HDX.

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).
A full size bus holds about 250 gallons of fuel. This make the range about 625 to 750mpg depending on the style of bus. The longest range electric bus made by Proterra was driven 1,101 miles on one charge. Most electric buses on the road today get 100- 250 miles to a charge.
Executive buses average 6 miles per gallon, especially when it comes to larger models that carry 45 to 51 passengers. Newer, high-tech models may get up to 10 to 12 miles per gallon. The larger the bus, the lower the average mileage.
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.
When specifying engines for your buses, you will notice that the engine rating has two numbers: horsepower (200, 220, 240, 260 etc.) and torque (520, 540, 600, 660 etc.). While these are related to one another, various applications have different needs in terms of the power or torque that are required.
A diesel engine requires less fuel to produce the same output as a gas engine. A conventional gas engine operates via a spark ignition system, which burns more fuel than a diesel engine's combustion system. As a result, diesel buses are more fuel-efficient per gallon and burn less fuel while idling.
A large cruise ship ranging in length from 900 to 1,100 feet might hold 1 to 2 million gallons of fuel. Smaller vessels, like a 440-foot-long ferry, might carry around 130,000 gallons of fuel, while a gigantic ship measuring over 1,300 feet in length can tote over 4 million gallons.
