No doubt Syn is good oil but that also depends on who's you purchase??
Some excellent things to think about in your post and all well presented.

Whoa, whoa, whoa there big fella! As a simple blanket statement, which is how you presented it, that is patently false. Incorrect. Wrong!

It very much depends on WHICH engine and WHICH synthetic oil. Not all engines are engineered the same and not all oils (synth or dino) are engineered the same either.

A synthetic which might provide superb wear protection for one engine, just might kill the lobes on a flat tappet motor in a hurry, especially considering the very low levels of ZDDP's in most synthetics.

What I took away from Irv's post, and I'm in agreement with him on this, is that there really isn't any need for "opinion" or speculation on this subject. There is data, science, facts, all available for the very low cost of regular UOA's that you can use.

Personally, I'll take a few UOA's over all the opinions, anecdotal evidence and internet expertise in the world.
