Conversely, those in consistently hot climates or who frequently tow heavy loads might prefer a higher summer viscosity to prevent the oil from breaking down and losing its lubricating properties. Synthetic oils are engineered for superior thermal stability, often maintaining their viscosity across a wider temperature range.

Driving Conditions and Climate Factors While the manual provides the baseline, real-world driving conditions can influence your choice within the recommended range. Benefits of Modern Synthetic Formulations Choosing a synthetic oil with a modern viscosity rating can provide benefits that extend beyond basic lubrication.
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). These oils are less prone to oxidation and shear breakdown, meaning they maintain their viscosity longer than conventional oils.

Using an oil that is too thin can cause excessive metal-to-metal contact, while oil that is too thick can starve the engine of oil, leading to overheating and sluggish performance. 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.
