I think you just proved my point that synthetic is not required

There are plenty of great conventional oils, and there are some crap synthetics. Either way if it meets the API ratings they specify and you are within the viscosity range it will work.
Yes you can use conventional oil but not oil change after oil changed so in that case in being able to use conventional oil you are correct but that is only if synthetic is not available. At my 7.5k service conventional oil was used and if they were to have used it again this time like they were going to then it would have been against what Subaru states in the owners manual.
