How to Choose Motorcycle Oil?
2 Answers
Consumers can simply follow the oil grade specified in the manual for replacement. In practical selection, one should not blindly pursue high-grade oil. According to the standards set by the American Petroleum Institute, SA is the lowest quality oil with no additives, and the quality improves as the grade increases. Mineral oil is entirely based on oil refined from petroleum. Since the performance of mineral base oil is not sufficient, it requires the addition of certain additives.
I've been commuting by motorcycle in the city for over a decade. My experience in selecting engine oil is that viscosity parameters are most crucial, such as the numerical combination like 10W-40, which represents cold and hot flow performance. I prefer synthetic oil—it's pricier but ensures smoother starts and longer engine life, especially eliminating the need to warm up the bike in winter. Motorcycle-specific oil contains additional additives to protect the clutch; never use car oil as it can damage the system. Changing oil every 5,000 kilometers is the baseline. In summer's high temperatures, opt for higher viscosity like 15W-50 to prevent thinning, while in winter, lower viscosity like 5W-30 facilitates easier starts. Regularly check the dipstick to avoid oil shortage. Stick with reputable brands like Shell or Castrol for peace of mind—don’t compromise with cheap off-brands. Overall, good oil reduces failure rates and saves on repair costs.
