Servicing buses should take place after the establishment of any problems with the vehicle, which can occur while driving or be determined at a standstill.Due to the fact that in Poland passenger transport by buses organized frequently by private carriers, who must themselves cover the costs of buying new vehicles, they try to take care of their vehicles so that they can ride as long as possible.
One way to prolong the life of vehicles is a frequent replacement of engine oil.

A V6 internal combustion engine from a Mercedes car An engine or motor is a machine designed to convert one form of energy into mechanical energy.12 Heat engines, including internal combustion engines and external combustion engines (such as steam engines), burn a fuel to create heat, which then creates a force.
Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others?such as clockwork motors in wind-up toys?use elastic energy.In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.Źródło: https://en.wikipedia.org/wiki/Engine
