RW> 8^) That's because on warm days, the oil's viscosity is thicker...

   For some reason, I used to think it was the opposite since heat normally makes   
   things thin out.   
      
   If you use 5w-40 or 10w-40, the cold morning starts would be at the 5w or 10w   
   weight though, correct?  I would think that when it is cold outside, the oil   
   would still go down and cause that lifter noise on startup.   
      
   I'm not aware of a 30w-30, but that might cause other issues.
