How much engine oil should be added to a scooter?

[AlyssaRose]

Different types of vehicles require different amounts of engine oil. Here is the relevant information: 1. Generally, a 125CC to 250CC engine requires one liter of engine oil. 2. Standard motorcycle engine oil is sold in one-liter bottles, so you only need to add one full bottle. 3. For engines below 110CC, 0.8 liters is sufficient, leaving 0.2 liters. Scooters typically require 0.8 liters, with exceptions for special cases. For imported heavy motorcycles, the amount usually ranges between 2.5 to 4 bottles. Additional information: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine.
