Well shortly after buying my car, I starting adding Castrol Syntec syntetic oil(at 79K,..I have 96K now). I change my oil every 3K miles. To be quite frank, buying this high dollar oil it killing me.

My question is....Is it ok to switch from my current oil to a conventional oil(Castrol GTX)?

I change my oil at 3K, but I've been told that with syntetic's it's ok to change it at 5K. Is this true?
