Welcome to pprune oldgrubber!
No intention of flaming a newbie, nor am I an expert in the S92.
However, my research (read: google search for "sikorsky ELS" - sometimes google is more effective finding stuff inside pprune than the build-in search function) led me to page 63 of this thread:

...I know, an obvious place to look for, but the fellow resident experts elaborating extensively over the emergency lube issue in particular on that very page; just follow the link.
