that's because the damage had already been done....synthetic oils are effectively "thinner" (lower apparent viscosity) when cold, so you get more blow-by in a higher wear engine, esp at start-up
I always run dino for about the first 3-4k miles and then immediately switch to synthetic, at that point you are far enough into the break in cycle that you need to start preventing excessive wear, the advantages of synthetic oils are extremely well documented is numerous peer reviewed journals

If you change your oil out often(3k or less), then there should (IMO) be no comparable excess wear with dino vs. synthetic. Dino's have improved a lot and compete very well with synthetics. I think the main benefit of sythetics is that extended protection when oil is changed less often.
There's a thread comparing dino vs. synthetic 10w30's and the mineral based oils did very well, even beating synthetics in some categories.

Personally, I use syntetic for longer oil change intervals. I think the use of synthetic to avoid engine damage is a bit of a wive's tale.

Exactly what damage has been done by using dino oil instead of synthetic with regular oil change intervals?? I have never seen a scientific study that shows that use of dino oil on regular change intervals causes any damage.......
I'm shocked how many AP1's on this forum blow through a quart in 3,000 miles...my old Chevy Nova did better than that!

It might not shear (breakdown) the same and after time change, but if it's signed with a ?w then that's it's "thinner" viscosity whether it be a dino or synthetic

Synthetics consistently beat dino oils in standardized tests, again, this is well documented

Here a link to a test done on 10w30's from a S2ki member:
