Motors and Oil over Grease

 In a car motor oil is used for lubricant. Almost all moving parts in the motor are lubricated using oil. But in on part of the motor oil is not used for lubricant that part is called the ignition. In the ignition oil is not used for lubricant. The ignition ignition fluid is used as a lubricant  instead of oil. When my dad first told me about motor oil the first thing i thought is why don't cars use grease for lubricants instead of oil. My dad told me it is because oil can be injected or squirted on the moving parts but grease cant do that. Engines are a machine that are designed to convert energy into useful mechanical motion. Heat engines including internal and external combustion engines  (such as steam engines) burn a fuel to create heat which is then used to create motion. Electric motors convert electric energy into mechanical motion. Pneumatic motors use compressed air to make mechanical energy. This my report on motors hope you enjoyed it.
