The mineral oil in the blend can introduce contaminants and lower the overall additive package efficiency. The primary benefits of synthetic oil—such as increased viscosity index, better flow in cold temperatures, and superior resistance to thermal breakdown—are compromised.
Understanding Engine Design Oil Mixing Limits
However, this method is generally not recommended by lubrication experts. This means the protection against wear, deposits, and high-temperature shear is reduced compared to using 100% synthetic, potentially leading to suboptimal engine performance over time.
The idea is to gradually introduce the new oil to "ease in" the change. If the manual calls for synthetic, relying on a mixture of regular and synthetic could put your coverage at risk if an engine-related claim is ever filed.
