What kind of oil should be used for motorcycles?
2 Answers
Here is the relevant introduction to the oil available for motorcycles: 1. Small-displacement motorcycles: For ordinary daily commuting small-displacement motorcycles, Shell AX5 or Castrol Superme will suffice. For better motorcycles, Great Wall Jaguar King Green Bottle 10W40 can be used. For large-displacement motorcycles that are frequently raced, imported oils such as Spain's Repsol, France's Motul, or America's Red Line, these world-famous synthetic oils, perform exceptionally well. 2. Large-displacement motorcycles: Motorcycles with large displacements certainly have higher engine RPMs, so the requirements for oil are relatively higher. Generally, in winter, 15W-40 (SG) is used, and in summer, 20W-50W (SG). It is essential to use high-quality oil, such as Total, Mobil, Esso, Great Wall, or Tongyi, but it must be genuine to ensure good engine maintenance.
With over a decade of motorcycle riding experience, I know firsthand how critical proper oil selection is. Since motorcycle engines and clutches share the same oil, you must use specialized motorcycle oil—never substitute automotive oil, or the wet clutch will slip, causing power loss, stalling, and serious hazards. Specifically, opt for JASO MA2-certified oils like SAE 10W-40 viscosity for most climates. Switch to 15W-50 in hot summers and 5W-40 for cold regions. Don’t slack on oil changes—I replace mine every 5,000 km or six months, cleaning the filter simultaneously. Trust motorcycle-specific lines from Shell or Castrol for affordability and reliability. Proper maintenance ensures quieter operation, extended engine life, smoother rides, and fuel savings.
