Yes, it is normal for a small amount of oil to come out of the exhaust of a two-stroke engine. Two-stroke engines use a mixture of oil and fuel for lubrication and combustion. As the engine runs, some of this oil-fuel mixture may pass through the combustion process and be expelled with the exhaust gases.
If you notice a significant amount of oil being expelled or if it is accompanied by other symptoms such as excessive smoke, loss of power, or unusual noises, it could indicate a problem with the engine's oiling system, such as a malfunctioning oil pump or an incorrect oil-fuel mixture.
If you're experiencing excessive oil coming out of the exhaust or any other concerning symptoms, it's advisable to have the engine inspected by a qualified technician to diagnose and address any underlying issues.
