Compound that with the fact that these engines have shit oil pressure and you're bound to spin 2 or 3. All 4 of my bearings looked seriously worn though, it was only a matter of time. I've opened up cars with way more miles than mine and the bearings were spotless. I think there is a misconception about rod/main bearings. They aren't actually the bearings. Think of the bearings as shims that are there to create the proper clearance for a perfect layer of oil (the actual bearing). If you have proper oiling then the bearings never make contact with anything other than on cold starts.

I hope for everyones sake you're wrong & that's it's a hit/miss issue associated with production. It would be a horrible & expensive nightmare to have an engine blow because of Subaru quality &/or design. Having said that my cars @50K miles is purring just fine & I always use TGMO 0W20, but I always dump it every 4,600miles max if not sooner. And my Blitz oil pressure & temp gauge always reads 15psi/1000rpm or more which seems quite healthy to me.
