Before I get any "use the search button" replys, I know there are a few engine oil threads already, and I read all the ones I could find.

From reading these other threads, it seems that a few people advised not to go fully synthetic until 12k and not to go back to mineral after being on synthetic.

Anyhows, my new 07 is about to tick over 1500k and I was preparing to buy some replacement oil. I was having a look at the running in oil that subaru gave me with the car, and its Fully Synthetic 5W-30. Reading the bottle it talks about the running in period etc etc.

Is this not strange, as others have stated subaru recommend not using synthetic until after 12k? Is subaru putting in fully synthetic from new now? Should I stick with the fully synthetic or go back to minerial / semi synth?

Any help appreciated.
Cheers
