So I took my vehicle in to dealer for the first 6000 miles service, and since I have the Subaru added maintenance plan, the plan clearly states synthetic. Don't know why, I just don't trust the dealer and kind have some kind of bad feelings towards the service. According to the receipt, they put in 7 qt of SOA635000 in the engine. I googled, not much info, found a eBay sold history for $2.03 a unit, and elsewhere saying it's a discounted item. So, what really is SOA635000? I doubt it's synthetic. I'm kind of pissed.
