I just posted a new UOA of GC gold, lot number M050756, in my 2003 BMW 330Ci. Wear is down in the second straight run of CG. The last GC UOA is also listed for comparison. It was mixture of 5 quarts gold and 2 quarts of green. Great oil for my BMW. I was at a dyno day last weekend and had my car running in the parking lot to warm it up. A fellow BMW club member saw my additional gauges and asked if they were on all the time, I said no only when the car is running. He couldn't believe my car was running, it was so quiet and smooth!
