RW> TW> I know you did not post the above but I mised it the first tiem   
   RW> TW> around and MUST comment. THAT is NO endorsement that can apply to   
   RW> TW> Automobile Engine oil changes. The operating conditions are Totally   
   RW> TW> different.   
      
   RW>Which is why I left it as is without comment. My SIL works for Continental   
   RW>Airlines as a maintenence mechanic in Houston, so I was going to wait to   
   RW>hear back from him on the use of oil in that industry.   
      
   Out of copuriosuity I checked on Avation Jet engine oil and guess what.   
   Mobile Jet Oil II(Aviation) is top rated!!  :-)   
   It costs $15.00 per quart though   
      
   But agai nthe Requitrements are so muchy different that it cannor be   
   compaitred to an Internal combustion oil. And even with the Piston   
   engiens since they are Air Colled the oil is different becasue of the   
   different operating conditions. NOW for a Corvair, Old VW or an   
   aircolled motorcycle there may be some comparisions of Interest of   
   Aviation oil.
