Should Honda Motorcycles Use 10W30 or 10W40?
1 Answers
Honda motorcycles should use 10W40. Here is additional information: 1. 10W30 vs. 10W40: Both 10W30 and 10W40 are all-season oils, but 10W30 offers slightly better performance than 10W40. For oil viscosity grades, the "W" stands for "Winter," and the number before the W indicates the oil's low-temperature fluidity. The smaller the number, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number after the W represents the oil's viscosity at 100°C. The larger the number, the higher the viscosity, and the better the high-temperature protection. 2. Differences: 10W30 and 10W40 have the same low-temperature fluidity, maintaining normal viscosity at temperatures above -25°C, ensuring the vehicle can start normally and the engine can operate smoothly. However, their high-temperature viscosities differ: 10W30 has lower high-temperature viscosity, better fluidity, and can reduce fuel consumption while allowing the engine to dissipate heat faster. However, after use, the engine noise may be relatively louder. 10W40 has higher high-temperature viscosity, is thicker, and can handle greater engine loads after use, resulting in quieter operation, less vibration, and greater stability. However, its fluidity is poorer, creating more resistance for internal engine components and consuming more fuel.
