Using Shell HX3 20W-50 engine oil in a new 110cc motorcycle may not be the best choice. Most new motorcycles, especially those with smaller engines like 110cc, typically require a specific type of engine oil that meets the manufacturer's specifications.
To determine the appropriate engine oil for your specific motorcycle, it's best to consult the owner's manual or contact the manufacturer or an authorized dealership. The owner's manual will provide the recommended viscosity grade and specifications for the engine oil.
Using an engine oil that is not recommended by the manufacturer can potentially lead to issues such as poor lubrication, increased wear, reduced performance, or even engine damage. It's important to choose an engine oil that meets the necessary specifications for your motorcycle's engine.
Therefore, I would advise referring to the manufacturer's recommendations or consulting a reputable dealership to ensure you are using the correct engine oil for your new 110cc motorcycle. They can provide you with the appropriate oil grade and brand that is suitable for your specific motorcycle model and ensure optimal performance and longevity of the engine.
