   I'm starting to wonder if the opposite might be what I want.  The main reason   
   being that I don't get the noisy lifter (cold tap) when the weather is warm or   
   hot.  The cold mornings, it does it the most and loudest.  On a hot summer   
   day, a cold start makes little to no noise.   
      
   Since the heat should be making the oil thinner, I would think that might be   
   the way to go.
