Oil is subjected to at least one centrifugal separation to remove contaminants prior to its being supplied to the lubricating system. Additionally, there is at least a portion of the flow that is returned to the sump after separation without its being circulated for lubricating purposes. All of the contaminant collection areas are in a noncritical area in an area of continuous flow and located so as not to return contaminants to the oil sump.
