G550 BR710 Oil Level

[BizJetEng]

Just wondering if any G550 engineers out there have anything in black and white from either GAC or RR regarding the engine oil level sitting happiest at -2. I have a client who maintains his engines at full and is wondering why his cowlings are covered in oil. Tried to explain to no avail.

Any and all help appreciated

I don't think there is anything written down, I always kept my engines lower than -2................when you have it correct the engines do about 50 hrs/pt.

Your 'client' is obviously a pilot who takes what FSI preach as gospel, just leave him to clean his own cowlings.

Have you looked throughout breakfast minuets/tech ops updates or what ever they are called now. Give tech ops a bell see if they know.
Always filled them -2 for the reason you give.

FWIW, same engines on a Global, the limitation is "for flights over three hours, oil quantity must be full". An operator at recurrent once told the story of his tech team kept them at 9.3 QT level on the panel quantity gauge. South of Iceland one winter night, both (:eek:) OIL QTY LO messages came on. When they landed at Luton, both engines needed about 5 quarts, IIRC. you really have to understand the upper/lower oil chambers and the gauging system before you play with oil servicing levels. I don't leave without 10.2 quarts.

Cheers all, high power ground runs carried out today clearly demonstrated to him what his cowlings look like now versus what they looked like prior to his aircrafts maintenance input...

gf, although same engine, both completely different gearbox and gauging system on a Global for me make the two aircraft incomparable!
