FAQ:
Q: What does 10W-40 mean?
A: It’s the oil’s viscosity grade. The “10W” indicates its performance in cold temperatures (lower is better), and “40” indicates its performance at high temperatures (higher is better for protection).
Q: How often should I change my motorcycle oil?
A: Check your owner’s manual for the recommended interval, but typically it’s every 3000-5000 miles (or more frequently under harsh conditions).
Q: What’s the difference between synthetic and conventional oil?
A: Synthetic oils are engineered for better performance at high and low temperatures, offering better protection and longer life. Conventional oils are more affordable but may not perform as well in extreme conditions.
Q: What is JASO MA2?
A: JASO MA2 is a specification that ensures the oil is suitable for motorcycles with wet clutches. It’s crucial for preventing clutch slippage.
Q: Can I mix different brands of motorcycle oil?
A: It’s generally not recommended to mix different brands or types of oil, especially synthetic and conventional. Sticking to the same type and brand ensures consistent performance and protection.
Q: What are the signs that I need an oil change?
A: Signs include low oil level on the dipstick, dark or dirty oil, unusual engine noise, or reduced engine performance. Regularly check your oil level.
Remember, this is a guide; always consult your motorcycle’s owner’s manual for specific oil recommendations. Happy riding!
