   Actually there is another listed among these. A Castrol full synthetic.   
   But like Amsoil, Castrol has always been a rare find wherever one goes. I   
   used Castrol in my 55 Chevy, c1960. But it was as rare then as their   
   synthetic seems to be today. I switched to Pennzoil back then and used it   
   for years after.

   I find the difference in price to be of no concern, as Mobil One is as   
   plentiful as Pennzoil these days. And, if push comes to shove while you're   
   in a remote area, you can always find Mobil One in any Mobile station.   
   Only on rare occasion do you find Pennzoil at a gas station.
