While a 5W-20 might be ideal for a fuel-efficient sedan, a high-performance SUV or truck might require a 15W-40 to handle higher loads and temperatures. The Science Behind Viscosity Grading Viscosity, simply put, is the oil's resistance to flow.
The Dangers of Using Thin Oil in Hot Conditions and Engine Damage
The multigrade system ingeniously solves this problem by combining two viscosity ratings. The number after the dash reflects the oil's thickness at high operating temperatures, where it must maintain a protective film.
The designation, such as 5W-30 or 10W-40, describes how the fluid behaves across different temperatures, balancing flow and protection. Furthermore, the right oil helps maintain optimal combustion chamber cleanliness.

Driving style also plays a role. Proper lubrication ensures that moving parts glide smoothly, minimizing the microscopic metal-to-metal contact that causes wear.
