Manual states 20W50 for hot weather. This sounds "heavy" but is not unusual for Euro engines of that era. I've started using 15W50 Mobil 1 (after doing a teardown on a 150K-mile BMW engine that had always run Mobil 1 I was sold). Oil is like a religious argument - you'll get a ton of opinions on this one, and unless you drive it 100K miles and then tear it down, you'll never figure out who's right. I know many folks running 10W30 without issue. In any case I'm convinced that full synthtetic is well worth the money.
