When an engine is running, the piston moves up and down inside the cylinder. The oil helps to lubricate the piston and the cylinder walls, reducing friction and wear. The oil also helps to cool the engine by absorbing heat from the piston and cylinder walls. Finally, the oil helps to seal the combustion chamber, preventing air and fuel from leaking out.
If an engine is run without oil, the moving parts will quickly overheat and seize. This is because the oil is not there to lubricate them, and the heat generated by the friction will cause the metal to expand and seize. The engine will also lose its ability to cool itself, which will further contribute to the damage.
Running a two-stroke engine without oil is a very serious problem that can cause significant damage to the engine. If you think your engine may be running low on oil, stop it immediately and check the oil level. If the oil level is low, add oil and start the engine again. If the engine continues to run poorly, you should take it to a mechanic for further diagnosis.
