Care and Operation of Multi - Cylinder Engines

All internal combustion engines are built to give long, trouble free service. An internal combustion engine, in order to operate, must have fuel, air, oil, and a coolant (usually water). The condition of these four items determines the useful life of an engine. Let's discuss each of these and attempt to point out desirable standards and how to combat below standard factors. Since the majority of engines used are gas engines, we will talk about natural gas as a fuel. Most gas used is a field gas and engine users don"t have much choice but to use it as it exists. In discussing fuel, we must also consider its effect on lubricating oil.
