Total ineo ecs is Cit recommended oil. There is an oil drain procedure as well, you can find it by googling. From memory you idle until fan comes on, stop engine then undo sump bolt and remove oil filter. Allow to drain for half hr. The purpose is to ensure all oil is drained. What does for turbo is old or wrong oil turning to sludge and blocking oil feed. Provided correct grade oil is used and changed at correct interval turbo should be ok.
