What kind of oil should be used for a 110cc underbone motorcycle?

[MacKarter]

For a 110cc underbone motorcycle, use oil with a grade of SF or above and a viscosity rating of 10W-40. Oil selection: Naturally aspirated engines have relatively modest requirements for oil quality, and mineral oil or semi-synthetic oil can be used. If the owner has a higher budget, fully synthetic oil can be adopted. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher oil performance. Oils with better fluidity are needed, and fully synthetic oil is recommended. Brand selection: When choosing a lubricant brand, if oil longevity is a priority, Mobil lubricants can be selected; if engine cleaning capability is a concern, Shell oil is recommended; for lubricants requiring strong oil film toughness, Castrol can be chosen. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning capabilities can be selected.
