A good reminder that your average jet engine pumps a lot more fuel around its internal plumbing than is actually metered and used. Consequently the fuel flow per hour indication is misleading for leak scenario purposes or checklists. And a massive leak source mask.
Allowing the engine to run with low oil Qty + reduced oil pressure + No Procedure + fumes + vibes + errant fuel status would worry me. Me + worry = Fuel off + land.
As an aside, sniffing used synthetic engine oil is a recommended practise for engineers, really?
