Hey man I understand money problems. However, the fact is regular oil changes SAVE YOU MONEY in the long run! $20-$60 every three months is a lot better than the hundreds or even thousands of dollars you will end up spending to repair the engine. That's how I knew you couldn't replace the head gaskets yourself b/c anyone who could, would also know how important it is to change the oil. I'm not trying to flame you, or make you feel bad, or rag on you for not having money. I'm just tellin it like it is.
