Parts that NEED oiling:
* Moving parts: The main purpose of engine oil is to lubricate moving parts, reducing friction and wear. This includes:
* Crankshaft and connecting rods: These transfer power from the pistons to the wheels.
* Pistons and piston rings: These move up and down within the cylinders, compressing the air-fuel mixture.
* Camshaft and valves: The camshaft opens and closes the valves to control the flow of air and fuel into the cylinders.
* Bearings: These support the crankshaft and other rotating components.
* Gears: These transmit power between different parts of the engine.
Parts that DO NOT need oiling:
* Non-moving parts: Parts that don't move or have minimal movement don't need direct lubrication. These include:
* Engine block: This is the main structure of the engine.
* Cylinder head: This covers the top of the cylinders.
* Exhaust manifold: This collects the exhaust gases from the cylinders.
* Intake manifold: This delivers air to the cylinders.
Important Notes:
* Cooling system: The engine's cooling system uses coolant, not oil, to regulate temperature.
* Fuel system: The fuel system uses fuel, not oil, to deliver fuel to the engine.
* Oil seals: While these are near moving parts, they are designed to prevent oil leaks and don't require oil themselves.
Think of engine oil as a vital fluid that helps the engine function smoothly and prevent excessive wear and tear. The parts that need oil are the ones that are constantly moving and creating friction, and oil acts as a lubricant to reduce this friction and protect the parts.
