Viscosity and Its Importance
While diesel engine owners reap the benefits of full synthetic oils, another critical aspect of engine oil selection comes into play: viscosity.
Viscosity measures the thickness and ease of flow in liquids, similar to how honey flows more easily when warm. The Society of Automotive Engineers (SAE) classifies engine oils into 14 winter and 8 summer viscosity classes, with winter grades determined by maximum viscosity at a given negative temperature.
Viscosity affects an engine's performance, protection, and economy, with different viscosities available for diverse vehicles and driving conditions, such as 0W-30, 5W-30, and 10W-30.
The viscosity index refers to the degree to which the viscosity of engine oil changes depending on temperature, with higher viscosity indexes indicating less change in viscosity.
Key aspects to ponder regarding viscosity include:
- Non-Newtonian behaviour: Engine oils exhibit non-Newtonian behaviour, meaning their viscosity changes depending on temperature and shear rate.
- Industrial applications: Viscosity is critical in industrial applications, where high-viscosity oils are often used to lubricate heavy machinery.
- Engine performance: Viscosity affects engine performance, with higher viscosities increasing engine internal resistance and power loss.
- Lubrication: The required engine oil viscosity varies depending on the characteristics of a car's engine, with lower viscosities potentially leading to inadequate lubrication.
When selecting an engine oil, it is essential to consider the viscosity that best suits your vehicle's needs.
For instance, Idemitsu's 5W-30 engine oil is suitable for diesel engines operating in a variety of temperatures.
Its advanced additive package and superior lubrication properties ensure optimal engine performance and protection.
