To refresh my thinking I just talked with an oil engineer at Kendall Oil Co. who advised an 85-90 weight no EP additive mineral oil for Summer driving. he advised against modern EP oils for any transmission or rear with bronze or brass parts. Kendall sells an oil called "
all oil gear lubricant" GL-1 in this weight with no EP additives.
Looking through early shop manuals many early 30s manuals not very definitive. A 32 Ford lubrication chart was shown which advised 220 weight in Summer and 110 weight in Winter. Chrysler manuals from this period do not define the weight but advise adding kerosene in the Winter.
My 30 Desoto has 5,000 miles on the odometer with no problems.
600 weight oil seems too heavy for this period but made sense in an earlier period when seal technology was much poorer.
I see no problem with 10-30 W oil in engines which begin with a clean oil pan. If the pan is filled with gunk no oil and no running is the best practice.
30 Desoto and 33 Chrysler CQ

George Michl, the master of early Chryslesr told me many years ago to swich with the 600 and 30 wt. oil. I think ,for my money I'nn stick with what was orrigionally used. I've only had 60 Chryslers from 1924 to 1930 and the ones
that I parted that had heavy oil in them were always in the best condition.
Food for thought. What Which would follow a spinning axel to the wheel end? Thick or thin oil?? I rest my case. It's your car, your money.
