Oil advice & recommendations from oilman @ Opie Oils

Just for some of the XUD9 owners info, the Fuchs/Silkolene Pro S 10w40 stuff, both Me, Darren and Ed used this oil, within 3-4 weeks, we all had uncontrollable oil leaks from the vacuum pumps... It's the only one we've found do it, but we've all used the Gulf Competition since and that's been perfect, seems very good, seems to last the longest without turning very black and watery to any I've used...
