This places additional stress on critical components like bearings and the camshaft. These additives are carefully calibrated by manufacturers to work within specific viscosity grades.
Diluting Synthetic Oil With Conventional: What Happens and Why It Matters
This change in viscosity can affect the oil's ability to flow through the engine's narrow passages. The real complexity lies in the additive package, which includes detergents, dispersants, anti-wear agents, and viscosity modifiers.
Modern engine oils are highly engineered products containing complex additive packages designed to perform specific functions. While a slight deviation is usually tolerable for topping off, a significant mismatch can lead to inadequate lubrication during cold starts or excessive friction during high-load conditions.
Diluting Synthetic Oil With Conventional: Understanding the Impact on Additives and Viscosity
Understanding Base Oils and Additive Technology The foundation of any engine oil is the base oil, which makes up roughly 70-90% of the final product. For example, adding conventional oil to a full synthetic blend dilutes the superior detergency and thermal stability of the synthetic.
