I can't speak for all Lycoming models , but redline on the O360A1A is 245F for oil inlet temp. I imagine the oil experiences a much greater temperature rise in these air cooled engine since Lycoming doesn't worry about burning off moisture until the oil remains below 140 or 160F(I forget the exact number). The vernatherm regulates to 180F for this reason. I am familiar with the higher temperature limits on oil for diesels (military applications), but do not think it is a good idea to replace Lycoming specifications with those of an entirely different type (water cooled) engine.
