Can ester-based synthetic oils be mixed with other oils?

True
False
Only with synthetic oils
Only with mineral oils

The correct answer is: False

Ester-based synthetic oils are not typically designed to be mixed with other types of oils, such as mineral oils or different synthetic oils, due to differing chemical properties and behaviors. Mixing these oils can lead to issues such as decreased lubrication performance, potential chemical reactions, or reduced oil stability. Ester-based synthetic oils have unique characteristics that differentiate them from mineral oils and various synthetic formulations, which can result in incompatibility in terms of viscosity, additives, and thermal stability. This incompatibility can impact the overall effectiveness of the lubrication system. Therefore, it is essential to use ester-based synthetic oils exclusively without mixing them with other oil types to maintain optimal performance and ensure the longevity of the equipment they are used in.
