Tays burn oil? Nah. When my old company first got the 100, the Fleet Manager asked RR what checks we should do in the event of an unscheduled overnight when there was no engineering available. The RR man didn't understand the question, so the FM said "well, what about oil level checks etc" The RR man thought a while and said "well, I suppose you could check the engine is still on the pylon, that's about all you need to do." Damn good engines. Mind you Fokker and RR had a good track record; F27/Dart, F28/Spey
