Over time, the inconsistent additive package may fail to control sludge or prevent acid buildup, leading to deposits on valve stems or bearings. For example, adding conventional oil to a full synthetic blend dilutes the superior detergency and thermal stability of the synthetic.

This change in viscosity can affect the oil's ability to flow through the engine's narrow passages. Viscosity and Immediate Performance Viscosity, or the oil's thickness, is the most critical factor when considering mixing engine oils.
The short answer is generally yes, you can mix engine oils, but doing so is not without consequences. 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.

Risks of Mixing Different Oil Types Beyond viscosity, the most significant risk comes from mixing conventional, synthetic, and synthetic blend oils. For optimal engine health, it is best to adhere strictly to the manufacturer's recommendations regarding oil specification and change intervals.
