Synthetic oil, however, is engineered for superior performance, offering better resistance to breakdown, enhanced protection at extreme temperatures, and improved fuel efficiency. Understanding Viscosity and Grades Viscosity refers to the oil’s thickness and its ability to flow at different temperatures.
Understanding Viscosity Grades and Oil Types
This essential fluid reduces friction between moving metal parts, carries away heat, and protects components from wear and corrosion. While older vehicles required changes every 3,000 miles, modern engines can often go 7,500 to 10,000 miles between services.
Viscosity Grade Best For 5W-20 Improved fuel economy and cold starts 5W-30 Balanced protection in most climates 10W-40 Older engines and warmer climates Conventional vs. This characteristic is represented by a code such as 5W-30 or 10W-40.
Understanding Viscosity Grades and Types of Engine Oil
Quality oil contains rust and oxidation inhibitors that neutralize these acids and form a protective layer on metal surfaces. The oil also plays a vital role in cooling the engine by absorbing and transferring heat away from combustion areas and friction points.
