u should go full synthetic...don't don't wat synpower mean..but i use mobile 1 5w30 full synthetic ever since i got my car and that's like 7 months ago so 2 oil change..other uses Royal Purple, Gastro GTX full synthetic, or amsoil which cost a ton..oh yeah, stay away from Fram oil filter while ur'e at it..hehe..they leak and breaks..i use Puralator or PureOne..
^^^ Valvoline Synpower is a full synthetic oil and that's what I'm using now. Durablend is a mixture of conventional oil and synthetic additives, it's not a full synthetic like Synpower.
And, I've never had any problems ever with FRAM oil filters. That's all I've used on my previous vehicles and now my Celica. No leaks or breaks!
