Glen, this is the latest in a long story.  You WERE running better 
oil than you are now.  SEMI-synthetic oil is generally part 
synthetic, part petro-oil.  You can silence those lifters by running 
a REAL synthetic oil.  Your choice.

Note: I'm not saying Valvoline 20-50 is bad oil.  It's good oil.  But 
Glen's post is more evidence that it's not AS good as synthetic; not 
even as good as semi-synthetic.
