Which statement is true about oil additives?

The statement that oil additives should be used as little as possible highlights a key point about the careful formulation of lubricants. While additives are essential for enhancing the properties of base oils, their effectiveness often depends on the correct balance and quantity. Using too many additives or excessively high concentrations can lead to negative interactions or ineffective lubrication, which may compromise the overall performance of the lubricant. Therefore, the notion of using them sparingly reflects the importance of optimizing additive concentration to achieve the desired benefits without overcomplicating the oil's chemistry.

Additives do play crucial roles in improving various properties such as viscosity, stability, and corrosion protection, but it's vital to strike the right balance to avoid diminishing returns. Understanding the function of each additive in relation to the base oil and the intended application is central to lubricant formulation.
