The Science Behind Viscosity Grading Viscosity, simply put, is the oil's resistance to flow. The multigrade system ingeniously solves this problem by combining two viscosity ratings.
Improved sealing capabilities between piston rings and cylinders. Choosing the Right Specification Selecting the correct engine oil multigrade requires more than looking at the dashboard.
Engine Oil Multigrade Seasonal Driving Guide
These advanced formulations are engineered to resist thermal breakdown and oxidation, which means they maintain their viscosity and protective qualities for longer service intervals. Seasonal Considerations and Driving Habits Drivers in regions with harsh seasonal shifts often rely heavily on the versatility of 10W-40 or 5W-30 formulations.
