The Role of Additives Additives are the secret sauce that tailors motor oil to specific engine requirements. Oil needs to be thin enough to flow quickly on a cold start to provide immediate lubrication, but thick enough to maintain a film strength when the engine is hot and under stress.
Understanding Motor Oil Additives Purpose and Functions
Additionally, modern detergents and dispersants in the oil work to suspend dirt, varnish, and other byproducts of fuel combustion, keeping them suspended until they can be trapped by the oil filter. Synthetic Blend A mixture of mineral and synthetic base oils.
This is why motor oil is labeled with a code such as 5W-30 or 10W-40. Detergents keep the engine clean, and rust inhibitors protect against corrosion caused by moisture and acids.
What Motor Oil Additives Do and Why They Matter
The base oil, which makes up the majority of the product, provides the fundamental lubrication properties. How Motor Oil Works Inside an Engine The primary role of motor oil is to create a thin film between moving metal components, such as the pistons and cylinder walls.
