Polyester oils mix with many other oils.

Explanation:
Polarity and compatibility control whether oils mix. Polyester oils contain ester groups, making them relatively polar. Most common base oils, like mineral oils or nonpolar synthetic oils, are nonpolar, so they don’t dissolve well in these polar esters. When you try to blend polyester oil with many other oils, the result is often phase separation rather than a uniform solution. That’s why the general tendency is poor miscibility with many oils, not widespread mixing. There are some rare exceptions where specific polar esters or specially designed blends can be compatible, but in general polyester oils do not mix with many other oils.
