Here's why:
* Separate Lubrication Systems: 4-cycle engines have a separate lubrication system that uses engine oil to lubricate moving parts.
* Fuel Tank: They have a fuel tank for gasoline or diesel fuel, which is kept separate from the oil.
* Oil Sump: The engine oil is stored in an oil sump, which is a reservoir located in the lower part of the engine.
Mixing Fuel and Oil in a 4-Cycle Engine:
If you mix fuel and oil in a 4-cycle engine, it can cause serious damage, including:
* Spark Plug Fouling: The oil in the fuel can foul the spark plugs, causing misfires and engine problems.
* Engine Damage: The oil can build up in the engine and create a sludge that can clog the engine's internal parts.
* Reduced Performance: The oil in the fuel can reduce engine performance and efficiency.
In summary: 4-cycle engines require separate fuel and oil, and mixing them can cause significant damage. Always follow the manufacturer's instructions for your specific engine.
