Here is an interesting YouTube review that compares 70-year old oil with modern oil. Apparently, there have been some advances in oil technology since the good old days: https://www.youtube.com/watch?v=-zHlxeu_yuM&feature=youtu.be

Great video find!   
If the Bullet survived 8,000 - 15,000 miles way back then on this stuff, Mobil 1 15W50 should be like manna from heaven to it. Thanks for sharing. - ACR -

     That can rings a lot of bells. I used a lot of QS in the '50s & '60s. Then it was Valvoline for quite a while and then into the Castrol & then Castrol GTX many years ago that I still use now.

Brings back memories of that green glop they sold back then. I remember Havoline 90wt smelled like garbage!
