   Just a follow up on a suggestion I received in this forum to try Castrol   
   Syntec blend to prevent the oil foaming which was occurring on my '06   
   Tundra.  I have about 2K miles on the 5w-30 Syntec blend now and this   
   absolutely cleared it up.  No more gunky foam all over the inside of the   
   filler cap like I was getting with conventional Penzoil 5w-30.   I am   
   considering going to straight Syntec next oil change since it seems like the   
   price is not much more then the blend.   
      
   Thanks!
