What kind of oil should be used for a 110cc underbone motorcycle?
3 Answers
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.
I've been riding my underbone 110 for over ten years, and choosing engine oil for this bike is quite particular. You must use motorcycle-specific oil - never cut corners by using car engine oil. The 10W-40 viscosity grade works best, providing high-temperature protection for the engine in summer while ensuring smooth cold starts in winter. Regular mineral oil suffices for my needs, changed every 1,500-2,000 km, though semi-synthetic is better for frequent long-distance riding. Pay special attention to the oil rating - SG is the minimum standard, while newer SJ-grade oils generally offer better durability. When changing oil, be careful not to exceed 0.8 liters, as overfilling can cause leaks and damage seals. I usually buy Great Wall Jiebao Wang or Shell Advance from authorized dealers - at 40 yuan per liter, it lasts me over half a year.
As a seasoned motorcycle enthusiast, I believe two key indicators matter most when choosing engine oil for underbone 110cc bikes. The viscosity must be 10W-40 - this range suits year-round use. The API rating should be at least SG grade, though SJ grade (current market mainstream) is preferable. Through real-world testing, I've found full synthetic oil, though pricier, extends oil change intervals to 3,000 km, proving more economical in the long run. Crucially, always opt for JASO MA-certified motorcycle-specific oil to prevent clutch slippage. During summer mountain rides when oil temperatures reach 100°C, conventional oils can't withstand the heat. I once experimented with 15W-50 oil and noticed noticeably stiff cold starts - 10W-40 remains the most balanced choice. Don't forget to clean the oil strainer during each oil change - a critical detail many overlook.
