Polyester oils are great because they can mix with a lot of other oils.

Explanation:
Polarity and compatibility govern how well oils mix. Polyester oils are polar esters, so they don’t mix readily with nonpolar oils like many mineral or hydrocarbon-based lubricants. They’re designed to be compatible mainly with other esters or specially formulated synthetic blends, not with a broad range of oils. Because of this, the idea that polyester oils can mix with a lot of other oils isn’t accurate; mixing them with incompatible oils can lead to separation and performance problems. Therefore, the statement is not true, and always check compatibility before mixing oils.
