   I already explained in great detail that it's not at all about money.   
   It's about design and function.   
      
   Most people want a simple answer to everything which money is to them.   
   But not everything is a simple dollars to dollars decision like you claimed.   
      
   If all you care about is money then knowing that both the oil filter and the   
   oil are cheap you're welcome to throw away both at the same interval which   
   is why I said it's up to you.   
      
   But stop saying it's about money when that's only how YOU think.   
   The manufacturers think differently than you think.   
      
   For them it's about engineering.   
      
   Many manufacturers recommend oil filter intervals different than oil.

   If you disagree with the manufacturer then you should answer this question:   
   Does the oil filter always fail at the exact same rate as does the oil?
