Adding more than the recommended amount of engine oil to your 125cc bike can potentially harm the engine. Here's why:
Engine oil serves several important functions, including lubricating moving parts, reducing friction, cooling the engine, and providing sealing between components. However, adding an excessive amount of oil can lead to various issues:
Increased internal pressure: Excess oil can cause increased pressure inside the engine, potentially leading to leaks in seals, gaskets, or other components not designed to handle the additional pressure.
Foaming: When the crankshaft whips through an excess amount of oil, it can cause the oil to foam. Foaming reduces the oil's ability to lubricate properly and can result in inadequate lubrication of engine components, leading to increased friction and wear.
Increased drag: Too much oil in the engine can create additional drag on the moving parts, causing the engine to work harder and potentially reducing performance and fuel efficiency.
Oil starvation: Surplus oil can disrupt the oil pump's proper operation, potentially leading to oil starvation in certain areas of the engine. This can result in insufficient lubrication to critical components, leading to increased wear and potentially engine damage.
To avoid these potential issues, it's important to adhere to the manufacturer's recommended oil capacity for your specific bike model. The recommended oil capacity is typically mentioned in the owner's manual or can be obtained from the manufacturer's website or authorized service center. If you have accidentally overfilled the oil, it's advisable to drain the excess oil to bring it to the correct level.
If you have concerns about the oil level or have already added an excessive amount, it's recommended to consult a professional mechanic or contact the manufacturer's customer service for guidance specific to your motorcycle model. They can provide the most accurate advice for your situation.
