What are the effects of overfilling oil in a scooter?

[MacArabella]

The effects of overfilling oil in a scooter: 1. The crankcase has a ventilation pipe, and adding too much oil will cause oil leakage. The high pressure in the crankcase can easily lead to oil seal leaks due to the elevated oil pressure. 2. Excessive oil may even enter the combustion chamber, forming blue smoke from the exhaust pipe after combustion, creating a false impression of oil burning. 3. The oil may flow into the air filter, causing insufficient air intake and affecting combustion, thereby impacting power and fuel consumption. The main functions of scooter oil are lubrication, cleaning, sealing, rust prevention, and cooling. The high-speed operation of scooter engine components and the combustion of the air-fuel mixture in the combustion chamber generate significant heat. Without proper lubrication from the oil, the engine can quickly seize or even fail due to high temperatures and severe friction.
