Regardless of the countless engineers studies that you can cite, I would probably be more inclined to come over to your school of thought if I ever saw an Acura engine fail for any reason. But I haven't. Not even semi-abused vehicles with well over 300,000 miles. Therefore I conclude that synthetic oils have very little benefit to anyone driving under non-severe conditions.
I've been in the car business for 15 years, and I'll be the last person to disuade anyone from doing right by their car. I've read of people having their oil analyzed by laboratories for all kinds of statistical research, etc. and I don't get it. It's wasted money and useless overanalysis.
Basically the moral of the story, if it feels right, do it
