What is the life expectancy of a bus?
In general, most American transit systems expect their buses to have a useful life of 12 years and 250,000 miles. This time frame is due to the fact that, after their buses have been around for 12 years, they are eligible to receive replacement bus funding from the federal government.
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.
Twelve years is the average life expectancy of a school bus, but if you aren't regularly performing thorough inspections on the wheels, brakes, fluids, lights, emergency equipment, etc., it will not last this long. Every school bus manufacturer provides a maintenance schedule that should be adhered to.
The longevity of a school bus and the fuel it runs on are not mutually exclusive. There are different factors to consider about the lifespan of a school bus – whether it's fueled by diesel or propane autogas. The average lifespan of a school bus is 12 to 15 years.
Nationally, 26 million children in the U.S. take 480,000 buses to and from school each day. School buses travel about 12,000 miles per year per bus or almost 6 billion cumulative miles per year.
Diesel engines are built to last and are specifically designed for medium-duty use. Diesel engines can last 15 to 20 years or more.
More fuel efficient: Diesel school buses can drive at 8.20 miles per gallon, whereas an electric school bus drives at 20.87 miles per diesel gallon equivalent — making them almost 60% more energy efficient.
This 1927 Blue Bird is the oldest surviving school bus in America. Albert Luce, Sr., built his first bus in 1925 by mounting a purchased wood body to a Ford truck frame.
Get organized—really organized. Bus life means cramped life. There's very little living space inside a bus once you add in everything you need to actually live, like beds, a bathroom, and storage spaces. The last thing you want to do is clutter up that space with more stuff.
How many miles can a school bus go on a tank of gas? It depends on the vehicle's gas tank size and fuel economy. 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.

"The zero emission bus pilot project has shown that Battery Electric Buses can operate in service, as an alternative to diesel buses," staff concluded.
Are gas or diesel buses better?
Diesel buses are usually the most expensive to fuel. But the fuel costs are usually the most stable, which makes budgeting easier. Diesel engines are also typically more fuel efficient than gas or propane engines.
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.
Early buses, known as trolleybuses, were powered by electricity supplied from overhead lines.
Type C: This is the most common school bus on the road and is considered the traditional school bus. Its conventional design is a flat chassis with a gross weight rating typically ranging between 23500 lb to 29500 lb. The bus is designed to carry 90 passengers.
Jet-powered school bus hits full throttle at 320 mph - CBS News.
Limited Cable Length − The central cable, or bus, in a bus topology has a limited length. If the cable becomes too long, it can cause signal loss and data errors. This means that bus topology is not suitable for large networks.
It may seem like bus drivers have easy jobs, but in fact, they are just as physically demanding as many others. While it is true that drivers sit for most of the day, it doesn't mean they don't experience wear and tear on their bodies.
What is the average gas mileage of a school bus? The average bus gets between 6 and 9 mpg, depending on many factors (size of bus, wind, speed, and of course how heavily loaded). That being said, it's not usually gas mileage. The majority of buses have diesel engines.

How many MPG does a Cummins school bus get?
7.5 mpg, cummins 5.9, ~70mph, at545, 4.7 rear, 21k lbs.
Finding buses with LOW mileage is uncommon, but don't be discouraged. My rule of thumb when I was shopping for a bus was a well maintained gas bus with under 100,000 miles or a well maintained diesel bus with under 200,000. In theory, a well maintained diesel engine can practically run forever.
A propane oil change takes seven quarts of oil: A diesel engine oil change requires 17-36 quarts of oil.
This happens because of a drop in lubrication. Simply speaking, gasoline is a solvent while diesel is an oil. Diesel has enough lubricity to lubricate the fuel pumps and the injectors. Swapping in some gasoline takes away this lubrication, leading to damage.
Since state officials froze school transportation funding levels more than 40 years ago, districts across California have cut back on bus routes or ended them; charged parents hundreds of dollars; or urged students to take public transit instead.

When oil has not been changed for a long time, it will begin to gel or solidify in an engine, eventually turning into sludge. When this happens, the oil will not be able to reach all parts of the engine, leading to oil starvation in the crankshafts, bearings, camshafts, and other valve train components.
Why do we have to change lubricant oil of bus engine?
Why change engine oil? The engine's oil gets used up over time and, every once in a while, it needs to be replaced. Replacing the engine's oil is crucial to maintaining high performance. It can therefore be one of the most important things you do to keep your car in good running condition.
Once opened, motor oil will be good for 2-5 years. if unused during that timeframe, it will start to break down and lose its effectiveness. How Long Can You Go Without an Oil Change? Most motor oils will last for about 5,000 miles before they need to be replaced.
