Agreed, if there is much interest let's spin off "oil consumption" to it's own thread. And BTW, cylinder bores and piston rings didn't have the degree of precision then as they did later; Packard service information as late as 1934 gave oil consumption in miles per gallon, not miles per quart! Specifically in 1934 they cited 2200 miles per gallon as typical for steady driving at 40 mph. At a steady 70 it was about 550 miles per gallon. At 20 mph it was about 3200 miles per gallon.

With today's precision boring/honing and improved rings etc., I today get about 1000 miles per quart from my 34 Eight.
