How do Oil Additives Work?

Oil additive will achieve a better performance which is measured by its thickness or the so-called viscosity by altering the viscosity of the motor oil. For instance, if the viscosity is too high, it can gunk up the engine and gradually be too thick to provide adequate performance. However, if it is too opaque, it will block your engine. With too runny mobility, it will run like water, missing its mark, thus lessening the protection to the engine. However, using an additive will put the motor oil to its correct viscosity and ensure the engine runs smoothly and at its best.
