Not all oils are created equal, and the quality of the oil you use can influence the efficiency of the oils in cooling the engines. Here are some factors to consider:
1. ViscosityViscosity can be defined as the degree of oil thickness and the manner in which the oil will flow at a given temperature.
However, if the oil is thick, it may not circulate in the system as fast to draw and shed heat in the process.
On the other hand, it may be too thin (low viscosity) and this would mean that it cannot effectively lubricate the moving parts which would result in high friction and heat.
As with modern multi-grade oils, they are formulated to provide the right viscosity at both high and low temperatures, making them suitable for lubrication and heat control.2. AdditivesSome of the additives enhance the heat stability of the oil while others aid in spreading heat within the oil in case of high temperatures.
For instance, detergents help maintain the cleanliness of the engine parts, which would otherwise be covered in sludge that hampers heat dissipation.3. Synthetic vs. Conventional OilsSynthetics are designed to perform better in severe conditions than conventional oils, including enhanced heat dissipation abilities.
They do not undergo chemical decomposition, remain stable at high temperatures, do not form deposits, and do not change their viscosity.
