Tim, it isn't that you haven't made any friends here, but your initial statement said pre-1955 and it has now evolved to a 1930 Packard. That's a difference of 24 years and a load of technology. No one is going to attempt to drive a 1930 Packard 90 mph but that isn't what you initially stated. The Packard 356 9 main bearing engine would sustain high speed driving and did so regularly, but it wasn't geared like a 1930 Packard. And to not take advantage of modern lubricants because a 1930 or 1947 owners manual doesn't recommend it is a little foolish. I only change my oil once a year, but i do it at the end of the driving season after driving less than 3,000 miles and my car sits all winter long with the bearings bathed in fresh oil. The many Packard owners who contribute to this and other old car forums share a wealth of knowledge and experience that only comes with time. If you just read and listen to their experiences you may learn a good deal.
