I will assume that you do NOT automatically assume that someone holding the status of shop foreman is an authority on the subject.

If you do - we have a problem since I was a Deere Ag. and Ind. shop-foreman for 12 years. So, how does one choose which shop foreman to believe? I say don't believe any of them and do your own research.

I don't assume that someone who is an engineer is automatically an authority either. I learned that a long time ago - especially with some Deere engineers I worked with. I'm picking on Deere - only because I've never worked along side any other sort of engineer. But, my father-in-law is a retired Ford engineer and he's filled me in a little about how things work in his type of world.

I use spec. charts from oil companies for my own peace-of-mind. And - judging from the oils and their specs - that I use - I disagree with much of what you stated. But - you are free to use what you wish - and believe what you want - just as I am.

Most synthetic oils have much more stabil bases in regard to viscosity and do not use the same polymers and petro-based oils.

As I said previously - when I'm in doubt - I don't like taking chances and prefer to use something proven by time - not by computerized projections (that are sometimes used).

In regard to the new oils being fine with Detroit 2-strokes? I still use the old standy - Rotella T 15W-40 in much of my stuff - but not my Detroits. I got two machines with 3-53s and one with a 3-71. The current data sheet for Rotella T 15W-40 reads (and note the Detroit comments) :
Shell Rotella T 15W-40 - 100 degrees C - 15.7 viscosity, 40 degrees C =- 118 vis.
Note: Detroit Diesel Series 53, 71, and 92 engines operating in ambient temperatures below
0°F - otherwise use straight 40W.
