How much engine oil is suitable for a 150cc motorcycle?

150 motorcycles are suitable for adding one liter of engine oil, not exceeding 1.3L. The lubrication function of engine oil: Supply oil to various bearings of the unit to lubricate and cool the bearings. In the sliding bearings of turbine units, turbine oil fills between the journal and bearing bush to form a fluid lubrication film, thereby playing a lubricating role. The supply function of engine oil: Provide stable and sufficient pressure oil for the regulation system and protection devices to ensure their normal operation. Supply lubricating oil for various transmission mechanisms. According to the function of turbine oil systems, the oil system is generally divided into two parts: the lubrication oil system and the regulation (protection) oil system.
I have over three years of experience riding a 150cc motorcycle, and changing the engine oil is quite important. The oil capacity does vary between different models. For the 150cc street bike I ride, it typically takes around 0.9 liters. When changing the oil, pay special attention to the method: park the bike on level ground, let it warm up for five minutes before shutting it off—this helps drain the old oil more thoroughly. Open the drain bolt at the bottom, place a waste oil container underneath, and wait 15 minutes for it to fully drain. Then tighten the bolt, use a funnel to slowly pour in the new oil, and stop at 0.9 liters. The most crucial step is checking the oil window or dipstick—the oil level should ideally be at the midpoint. Never overfill it; last time I added an extra 50ml, and the engine sounded muffled with blue smoke. I recommend using 10W-40 full synthetic oil and changing it every 2,000 kilometers for optimal engine protection.
