A school bus can generally hold between 50 and 100 gallons of diesel fuel. This varies with the size and the brand of bus.
I could be wrong, but I owned a full size school bus, and I believe it held 50 gallons.
As much as the engine manufacturer specifies.
As much as the tank installed in it was intended to hold. There isn't one single answer applicable to all classes, makes, and models of school buses.
A standard diesel engine weighs 798 lbs
The transmission fluid fill cap on a 1989 Chevy school bus with a diesel engine is under the air filter. The air filter has to be removed to see it.
As much as the fuel tank is designed to hold. Your larger buses are all diesel or CNG anymore, so you'd be looking at a small- to mid-sized bus if you were running on petrol (some prefer it over diesel, because they don't have to deal with diesel aftertreatment systems with a petrol engine), so we're talking 20 - 100 gallons, dependent on the size of the bus and the configuration.
My 1979 International 1723 gas school bus weight is 21,700 lbs. The 1980 should be very similar. I wouldn't think Gas v/s Diesel would change the weight that much.
Chemical energy. The petrol / diesel that you fill up the tank with.
Depends on the size of the school bus, size of the fuel tank, if it has a diesel or gasoline engine, and the mpg it will get. None of which you list.
Roughly 6mpg highway. They hold about 300 gallons almost always diesel.
A school bus from Bx to Queens is $13.00.
