Even if he did run synthetic oil since the beginning, it wouldn't have saved his engine if the engine had a design flaw, or if during the production run, there was a bad batch of engines or parts.

Mobil Super 3000x1 is Group III synthetic oil, and AFAIK it's not related with US Super 3000 or 5000 mineral oils. Not that it really matters, problem I have is not oil related, it happen due to detonation or/and lean mixture on that cylinder. It rarely happens on atmospheric engines, but it does.

Shell/Pennzoil Ultra is cheap oil? How so?
What would you suggest he run in his econobox instead? Redline?
Non-spirited puddling around the suburbs? Shell Helix Ultra AS 0W-30 (or the newer "Helix Ultra A5/B5" 0W-30 with PurePlus) resp. any other Fiat 9.55535-G1 fuel economy oil.

OK, update on this; I removed head to found cracked piston ring on second cylinder, and lots of marks on that cylinder. Others looked great and had good compression. (did dry and wet test). So I bought 1.4 Stilo bottom end and going to put head and all ancillaries from old engine. There are some issues (need remap and crank sensor bracket needs to be modified), but overall I think this will work. Standard Stilo have 95 hp, but with my better camshafts and manifolds I'm thinking 100 hp is possible. Car weight 930 kg so it will be fun and economy would also be decent.

He was using fully synthetic Shell Ultra 5w-40...
I think Fiat are quite keen to use 10w-40 semi synthetic oils only in these engines so they certainly have no problems with cheaper semi synthetic oils
Fiat know a thing or two about oils as well, they had their own oil company for a long time - Fiat Lubrificante.
