Why Thicker Motor Oil Isn’t Better For Your Engine
Oil Viscosity Explained: Thick vs Thin Oil Myths Debunked Quick Summary Thicker oil doesn’t automatically protect your engine better. Instead, motor oil viscosity must match the engine design, operating temperature, and oil control, not old-school assumptions. Controlled dyno testing shows that low-viscosity oil versus high-viscosity oil reveals clear trade-offs among friction, power, oil flow, and wear. Thicker oil can reduce wear in some situations, but it can also increase friction, slow oil delivery, and cost horsepower. The real answer isn’t “thick or thin”—it’s using the right oil viscosity for the … Read More
Understanding Oil Viscosity: A Guide for Car Owners
Exploring the Importance of Oil Viscosity Modern motor oil is multi-viscosity. So, it has a slower flow rate when it’s cold and a faster flow rate when it’s hot. That’s why all multi-grade motor oils show two numbers. The first number, the one in front of the “W” (stands for Winter, not Wax), represents the oil’s viscosity at 0°F -17.8°C (its cold start performance). The second number, after the dash (—) represents the oil’s viscosity at 212°F (100°C). So a multi-grade oil viscosity may be shown as 0W-16, 0W-20, 5W-20, … Read More
