When is oil cleaning and filtration most effective?

Oil cleaning and filtration are most effective at high temperatures and low viscosity because this combination promotes improved flow characteristics, which facilitate better interaction with the filtration system and the contaminants being removed.

When oil is heated, its viscosity decreases, making it easier to pass through filters and allowing for more effective separation of particulates and impurities. Lower viscosity oils can move more freely, helping to carry contaminants into the filter media, where they can be captured and removed. Additionally, higher temperatures can help to dissolve or loosen sludge and other deposits, contributing to a more thorough cleaning process during filtration.

In contrast, operating at low temperatures can result in high viscosity, causing challenges in the filtration process as oil will flow more sluggishly and may not effectively reach the filters. Therefore, high temperature and low viscosity create the optimal conditions for efficient oil cleaning and filtration.
