It is generally not recommended to use engine oil additives unless specifically recommended by the manufacturer or mentioned in the owner's manual. Engine oil additives are designed to modify the properties of the oil to enhance certain aspects such as lubrication, cleaning, or protection. However, modern motorcycle engines are designed to work optimally with the recommended grade and type of engine oil without the need for additional additives.
Using engine oil additives that are not recommended by the manufacturer may interfere with the engine's performance or potentially cause damage. It's best to stick with the manufacturer's recommendations and use the appropriate grade and type of engine oil specified for your Suzuki Burgman Street 125cc BS6 model.
If you have concerns about the performance or condition of your engine oil, it is recommended to consult your owner's manual or contact a certified Suzuki service center for guidance. They will be able to provide you with accurate information and advice based on the specific requirements of your motorcycle model.
