   RN>I'm not too particular about the gas, although I have to use 93 octane, but   
   RN>oil is of utmost importance.  I use Castrol GTX 10W-30 in my Lincoln (It sho

   Living in Southern Califronia(Warmer Climate) I used Castrol 20-50 for   
   many years. I have gone to a full synethic Penzoil for my Toyota   
   Truck(finally dumped my Piece of CRAP Chev S-10) and have High Miledge   
   Penzoil put in the Wifes Subaru with a little over 282,000 miles on it.
