Understanding the Differences between 10W-30 and 10W-40

10W-30 and 10W-40 are common grades of engine oil, and the choice between them may depend on various factors such as ambient temperature and engine components.

For Initial Oil Changes

For initial oil changes and general maintenance, a 10W-30 grade is typically preferred. This viscosity type provides better lubrication and is suitable for a wide range of temperatures. The 10W part indicates it is designed to flow better at lower temperatures, while the 30 provides adequate protection at higher temperatures.

For Long-Term Performance

After the second service, it is advisable to switch to a 10W-40 grade for better gliding of engine parts. This grade provides a thicker layer of protection and ensures smoother engine operation. The higher viscosity ensures better film strength, which is crucial for long-term performance and protection against wear and tear.

Why Synthetic Oils are Preferred

Synthetic oils offer several advantages over conventional oils, making them a preferred choice for many motorcycle owners. Here’s why:

Better Resistance to Extreme Conditions: Synthetic oils have a higher resistance to thermal and oxidative stress, making them suitable for extreme operating conditions. They maintain their performance even when exposed to high temperatures and pressure. Better Protection: Synthetic oils are designed to enhance engine protection by reducing wear and tear, thus extending the life of your engine components. Better Fuel Efficiency: Synthetic oils can improve fuel efficiency by reducing engine friction, leading to better overall performance. Better Fluid Retention: Synthetic oils have better fluid retention properties, which means they stay in the engine longer and provide better protection over time.

Conclusion

Choosing the right engine oil for your Honda Unicorn 150cc BS4 is a crucial step in maintaining its performance and longevity. A 10W-30 or 10W-40 grade, adhering to API standards like SL or higher, is recommended. Popular options include Castrol Activ 4T 10W-30, Mobil 1 10W-30, Shell Advance 4T 10W-40, and Motul 3000 4T 20W-50.

Switching from 10W-30 to 10W-40 after the second service can further enhance the gliding of engine parts and provide better protection. Additionally, synthetic oils offer better performance and protection, especially in extreme conditions. Always refer to your owner's manual for specific recommendations and oil change intervals.
