An engine lubricating oil system comprises a centrifugal separator (4) placed in a lubricating oil flow circuit so that oil passes therethrough to be cleaned. The separator has a hollow rotor body (102) and engages powered drive means (107), so that the drive is independent of the flow through the rotor. The separator may be placed between the sump and the engines working parts to act as a full flow filter or may continuously filter the sump oil. |
