We consider engine oil analysis to be a valuable early warning system for certain types of engine problems. It allows an aircraft owner and maintenance technician to catch those problems before they become safety of flight items.
Because we feel it’s valuable, we wanted to know more about the labs that perform it. Do they give results consistent with each other? What is the turnaround time for a sample? Can they explain the results of a sample in a way that makes sense to an aircraft owner? Is there information on their website about the process and results clearly?
