**** Why; is it just the pre-mixing,  or are there some other unwanted
engine side effects?
 
That is it. Probably a 2 gallon jug to lug with you and a few cans of oil. Then the added time at the pump while others wait.

****What do you mean by "dyno oil"
 
Oil from decaying dinosaurs and vegetation. The source of oil as found in books from the 50s. Not true, but what old people think is the origin of oil in the ground.
 
Synthetic oil is still oil. it is refined to the point that most of the molecules are the same size.
Additives to improve film strength may be from other than oil sources. Film strength is generally much higher than conventional oils. Much more stable at very high temperatures.
Thus a poor choice for stock rotaries that use the sump oil to inject for apex seal lube, since it does not burn at operating temperatures, and thus gums up the apex seal grooves.
