The Definitive Guide To Motorcycle Engine Oil
From the saddle, you'd never imagine the violence occurring inside your engine cases as you cruise down the road. There's a dizzying number of parts spinning and reciprocating inside your motor—some of them at hundreds of times per second. And all those components rely on a pitifully thin film of oil to keep them from turning to slag and bringing the whole mess to a screeching halt.
Motorcycle Engine Oil Viscosity And What The Numbers Mean
Viscosity:
- Viscosity refers to the oil's thickness—the higher the rating (e.g., 50 weight), the heavier or more viscous the oil is.
- Modern multi-viscosity oils provide the right flow characteristics and lubrication across a wide range of temperatures.
- The “W” in 15W-50 stands for winter, indicating the fluid's flow rate at seriously low temperatures (around -15 to -20 degrees Fahrenheit).
- The second number (e.g., 50 in 15W-50) represents the oil's high-temperature viscosity at 212 degrees Fahrenheit during normal operation.
Additives:
- Chemists mix in viscosity index improvers (VII) that expand and elongate when hot, increasing the oil's viscosity.
- These additives allow a 15-weight oil to thicken to 50-weight once hot.
Choosing the Right Oil
- Your motorcycle's manufacturer specifies the viscosity range that meets the motor's needs. Abide by its recommendation.
- Remember that oil is your engine's lifeblood—it keeps things spinning smoothly, cools the transmission and pistons, helps piston rings seal combustion pressure, and neutralizes harmful chemicals.
In summary, selecting the right motorcycle engine oil involves understanding viscosity, additives, and adhering to manufacturer recommendations. Keep your engine well-lubricated, and ride safe! 🏍️
