But what I`ve always wondered,are synthetics such as PAO based oils better at preventing wear than a dino,or are they just better at keeping engines clean during extended oci`s.

From what I can tell, they mostly just hold up better in extreme conditions and keep protecting when a conventional oil would start to break down. If you look at conditions in which a conventional oil would survive, I doubt you'd see much of a difference.

I think it's because PAO is the best way to achieve good performance at very low temperatures.
No one really knows for sure except the oil companies themselves. This is a somewhat-educated guess.

Right and they use Grp II I think it is as the carrier for the add pack.
Why Group II, I thought PAO is Group IV.

It's an additive carrier. PAO / Group 4 won't keep the additives in suspension/dissolved/solution/what-have-you the same way Group 2 does.

Solvency runs Group V > Group I > Group II/II+ > Group III > Group IV/PAO. The higher the solvency, the more choices of additives you can have. A pure PAO oil would perform poorly. The basestock would be great, giving great VI and oxidative resistance, but the additives would be inferior to a III, and thus you lose out on all the other aspects of oil (detergency, wear protection, emulsion retension, etc.)
Don't take my word for it, but I believe GC and Castrol Edge are III/IV/V blends, while Amsoil/RP is IV with just the tiniest bit of Group I or II. PP as everyone knows is a III.

Uh, wrong on almost all accounts.
Redline is absolutely not PAO. It's a fully polyolester basestock. Group V ester.
Schaeffers 9000 is probably PAO basestock. But its flagship (and actually API'ed) 7000 is a blend.
Motul is also a Group V, and doesn't use PAO.
Eneos is a PAO/Ester blend, which also makes it not all-PAO.
Finally RLI is a PAO/Vegetable oil blend, which makes it IV/V. Also not all PAO.

Not true either. Redline uses PAO along with their esters. Not that it matters. Obviously they know what they are doing and make a great oil, but the oils do contain varying amounts of PAO's. One time YEARS ago someone asked Redline and it was 20-40% range for PAO. I doubt they would be that forthcoming nowadays.
Any oil that is 100% ester base will have some real issues and will be REALLY expensive.

Schaeffer's 9000 series is a blend of Group III and PAO.
Hard to tell about Eneos. Some of their products are all Group III. I doubt they use much Ester base stocks.
Motul's line of products are mostly Group III or PAO. Their 8100 series has some Esters in it and their Racing 300V has high Ester content but none are all Ester.
