Practical Buying Advice:

Consider your bike’s type, riding style, and climate when choosing your oil. High-performance engines and hot climates benefit from thicker viscosities (like 10W-50 or 20W-50), while milder climates and less demanding engines may be fine with a thinner viscosity (like 10W-40 or 5W-40). Always check your motorcycle’s owner’s manual for the recommended viscosity and specifications.
