Choosing the correct viscosity grade, often denoted by standards such as SAE (e. These base stocks are categorized into two main groups: mineral oils and synthetic oils.

The oil also plays a crucial role in sealing, helping to maintain compression in combustion chambers and preventing the ingress of combustion gases. These additives perform a multitude of crucial functions, including preventing oxidation and sludge formation, reducing friction beyond what the base stock can achieve, inhibiting corrosion on metal surfaces, and suspending contaminants within the oil until they can be filtered out.
Conversely, an oil that is too thick (high viscosity) can cause excessive drag, reducing energy efficiency and hindering the oil's ability to circulate and reach critical components. An oil that is too thin (low viscosity) will not maintain a sufficient film strength under load, leading to increased wear.
