I'm not an expert and am looking forward to answers from those who are but, until recently, I always ran standard 30w in all my older cars including Packards. In fact, my 1954 Packard Patrician has 30w graphite oil which was available decades ago and was so "slippery" that I had to turn down the idle speed, then turn it down yet again after adding multi-tip spark plugs. However, now I run multi-viscosity 10-40 or similar and am a firm believer in synthetic lubricants of any sort.
