Greetings,

Well, I am finally getting to the point in my project of thinking about which
oil to use in my engine.  What a great feeling!!

I have a new IO-320 installed and am looking for suggestions for both break-in
oil and an oil to use long term.  I have read all the Lycoming publications on
break-in and will use a MIL-6082 mineral oil like Phillips Type M (20W-50).  
Any better recommendation for brand or weight for break-in?

Does anybody out there have a strong recommendation for a particular brand of
AD oil for post break-in operation?  Phillips?  Aeroshell?  etc...

Thanks!

Dan Olsen
