How to find the Right Engine Oil for 100cc Bike
- Consult Your Owner’s Manual
The ultimate guide for your bike’s needs is your owner’s manual. It specifies the recommended oil type, viscosity grade, and change intervals. Using the wrong oil can damage the engine and void your warranty.
- Understand Viscosity Grades
Viscosity refers to the oil’s resistance to flow. It is denoted by a two-number code, such as 10W30 or 20W50. The first number indicates the oil’s viscosity at low temperatures, and the second at high temperatures.
For 100cc bikes, 10W30 or 10W40 viscosity is recommended due to India’s climatic conditions and riding styles. These oils provide a good balance of low-temperature flow for easy starting and high-temperature protection for operation.
- Lower viscosity oils (like 10W30) are ideal for colder climates as they flow easily, ensuring quick lubrication during start-up.
- Higher viscosity oils (like 20W50) are better for hot climates and high-performance engines because they maintain their thickness at higher temperatures.
FAQs

Yes, but it’s more expensive. Semi-synthetic offers a good balance.
- What is the right viscosity grade for a 100cc bike?
