The FA Motor has been out a full 3 years now and the question has been asked 1 million times.
I'm not 100% sure. As long as you do say an oil change every 3500-3700 miles using that oil I think you'd be ok. On another forum they did a UOA from Blackstone and Valvoline oil sheared down to a 20 weight. If you're looking for an easy place to get oil done without doing it yourself I'd opt for Pennzoil Platinum Ultra 5W30 or a 'more' synthetic variant like Motul or Eneos. I have to find my Blackstone UOA for Motul 8100 xclean. I know guys I'm here like Amsoil or Redline as well.
Where are you located?
^agreed. Seems the FA motors like to drink Synpower, and Mobile 1. In NJ there is an AZP shop that can do Motul, and Eneos, or for $20 bucks bring them the oil and filter and they'll do it for you
If you have the ramps and tools (i.e. oil filter wrench and socket for the oil plug) this really should be a 15-30 minute job at tops. Subaru has made changing the oil ridiculously easy with the top mounted oil filter and easy-to-access oil pan drain plug. Sometimes it seems as though I spend more time finding the right socket than the time spent doing the oil change.
That's what I meant. The FA and EJ like to drink as in burn through Mobil 1 and Synpower pretty quickly so definitely stay away from those because of the shearing problems. I was recommending Pennzoil Platinum Ultra 5W30 if you were to use something readily available. Otherwise Redline, Amsoil, Motul, etc are much better options.
