The recommended engine oil for a Honda Unicorn 150cc motorcycle can vary depending on factors such as the climate and the specific requirements of the motorcycle. It is always best to consult the owner's manual or contact an authorized Honda service center for the most accurate and up-to-date information.
That being said, Honda typically recommends using a 10W-30 or 10W-40 viscosity grade engine oil for the Honda Unicorn 150cc. It is also important to choose an engine oil that meets the specifications and standards recommended by Honda. Look for oils that meet the JASO MA or MA2 standards, as these are specifically designed for motorcycles with wet clutches like the Honda Unicorn.
Popular brands that offer high-quality engine oils suitable for motorcycles include Castrol, Mobil, Shell, and Motul, among others. However, always ensure that the oil you choose meets the specifications and standards mentioned in the owner's manual or recommended by Honda to ensure optimal performance and protection for your motorcycle's engine.
