Yes, n/a Subaru's can use most any oil and easily go to 7,500 miles on most synthetics and especially if it is a more robust oil.
Subaru does not use a break-in oil. I've seen folks from Subaru Indiana Automotive (Outbacks/Legacy's) post this as well as people that received info about the Gunma plant (Foresters/Imprezas). The high moly could be from assembly lube and the moly coated pistons.
Check subaruforester.org and there are a few polls on head gasket problems by MY and engine type. Like Subes said, the HG problems are not like they used to be. I'm also curious to know the Forester forum you're referring to.
And for the reports of higher consumption with M1, it's likely the turbo models that are being referred to and pretty much the same applies for any Energy Conserving oil, IMHO. There are guys with highly modified STI's running thin 30 grades.
