Just changed my BB OIL this weekend...on the advice of my dealer-after the GreyGoose's lockup...
I had the same issue as Laurens, thick black goo that needed some serious flushing.
To be honest, I only flushed the box twice, with Red Line 80/140...frankly It still took some serious agitation with a pipe cleaner to get some of the black goop out...and I'm sure there is still 25% - 50% of the old goo/oil in there...a very dirty job.
I topped the bevel box off till some oil leaked through the fill hole. I plan to drive the car gently around town for a week or so, and then do another change. Hopefully that will allow the new oil to mix with the goo and allow a proper flush.
I did this change outside, in 100 degree weather after letting the car sit in the direct sun for 4 hours and then driving for 20 minutes, and the goo way still as thick as molasses...
I worried about flushing with gasoline or another solvent, but frankly, I can't imagine this goop clearing easily without 3 or 4 changes...
