RW> My thinking is that if the oil used is heavier, it will be less likely   
   RW> for the lifter to leak down. You could also go with a single weight oil   
   RW> such as 30w and get the same effect.   
      
   I'll try the 10w-40 synthetic on my next change.     
      
   Would 20w-50 be too thick and cause a possible gasket blowout?  I used that   
   type of oil in the old Malibu and my daughter's car to "slow down" the oil   
   leaking.  The thicker it was, the less oil would leak out.
