I use Total Quartz Racing 10W-50, formerly Elf Oil.
A good price is about $29 for 5 liters.

I get mine locally in Michigan at S & G http://www.sgparts.com/ their prices
are very competitive, and much lower than Mobil 1.

"Common knowledge" in 1945 excluded CAD/CAM and modern metallurgy, too.
Things change.
