What Type of Engine Oil Should Be Used During the Break-in Period of a Motorcycle?
2 Answers
During the break-in period, engine oil with lower viscosity is generally recommended, and it should have excellent anti-wear properties. Engine oil with lower viscosity offers better fluidity and cleaning performance, which helps more effectively in dissipating heat and removing fine debris generated during the break-in process. Anti-wear properties refer to the lubricant's ability to prevent metal wear caused by friction between metal parts. Better anti-wear properties help the engine "smoothly" pass through the break-in period. Break-in period taboos: Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. Avoid overloading: If a new vehicle is operated at full load during the break-in period, it can cause damage to the components. Therefore, within the first 1000 kilometers of driving, the load should generally not exceed 75%-80% of the rated capacity. Avoid long-distance trips: Taking long-distance trips with a new vehicle during the break-in period increases the continuous working time of the engine, which can easily lead to component wear.
When I first bought my new motorcycle, I was particularly concerned about how to choose the right engine oil during the break-in period. The break-in period refers to the initial stage when a new engine starts running, where various components need moderate wear to adapt to each other. I used mineral oil, such as SAE 10W-40, because its viscosity is just right—it helps the friction surfaces wear in more evenly. Unlike synthetic oil, which is too slippery and can prevent components from wearing in properly. I remember changing it at the first service, and after riding 500 km, I checked the oil and found it had turned a bit black, which is normal as it means impurities were being carried away. Also, avoid speeding or sudden acceleration during this period; ride gently to ensure a longer engine life. After the break-in period, I switched to synthetic oil for better protection. Now, my bike has run over 10,000 km without major issues. I recommend new riders do the same—buy a reputable brand of mineral oil; it’s affordable and practical. Don’t ignore the manual’s recommendations, as each bike might have slight differences, but mineral oil is generally universal. Regularly checking things like chain lubrication is also crucial for overall bike condition.
