Question Engine Oil: Lubro Moly vs. Royal Purple


I just want to get a feel for what people on here think. This site is great and I value everyone's opinion. I have always used BMW oil in my '99 323i. It has 170,000 miles on it and runs great. I've heard great things about both of these oils, and I wanted to get some feedback before I do the change. Thanks guys!

Oil selected must meet ACEA A3,B3 and LL01. So how are you going to select which RP oil when they don't test to these stds and worse are the only oil company which won't give you the HTHS specs which are critical to
E46 engines? And now hauled over the coals for false advertising. Best you give them a wide berth. Lubro moly have a 5W40 which mets specs I believe.
