My understanding is it is not the weight of the oil, but the service grade (GL1, etc) that determines if it is safe for use with bronze parts. There was a thread on this a while back and some of the guys were saying the newer formulas are safe for bronze gears....but you need to specifically check.

My local oil jobber stocks the older gear old without the additives that cause all the problems with bronze parts. You may not find it at your local box store.
