The higher this number is, the thicker the oil will be.

3) Protection against Wear: The high viscosity rating of this engine oil helps to form a protective layer on metal surfaces, reducing wear and tear on your bike’s engine.

4) High-Temperature Stability: With its thicker consistency at high temperatures, 15W-40 engine oil can withstand extreme heat without thinning out or breaking down quickly.

5) Fuel Economy: This type of engine oil has additives that improve fuel efficiency by reducing friction between moving parts.
