Modern engines are engineered with tight tolerances that require specific viscosity levels to function correctly. The Science Behind Temperature Ratings The second number following the dash represents the oil's viscosity at the engine's normal operating temperature, typically around 212°F (100°C).
Understanding Oil Viscosity Ratings and Temperature Performance
Conventional Oil Viscosity Advancements in lubrication technology mean that the car oil viscosity chart applies to both conventional and synthetic blends, but the two types behave differently. This portion of the car oil viscosity chart measures the oil's thickness and its ability to maintain a protective film under heat and stress.
Higher numbers, such as 30 or 40, indicate a thicker oil that creates a stronger lubricant barrier but may slightly reduce fuel economy in colder climates. Benefits of Modern Synthetic Formulations Choosing a synthetic oil with a modern viscosity rating can provide benefits that extend beyond basic lubrication.
Understanding the Science Behind Temperature Ratings and Viscosity Levels
In reality, using a 10W-60 in a engine designed for 5W-20 can cause the engine to work harder, reducing power and increasing emissions. This allows synthetic oils to offer better protection in extreme heat and cold, and they tend to flow more readily at startup, which is a significant advantage reflected in modern viscosity ratings.
