Re: Robert Smiley's comment about breaking in aircraft engines with castor
oil.

Where did that come from? Neither Cont. or Lyc. recommends such a thing in
ANY of their break-in procedures that I've ever seen. What they DO require
(at least for most of their engines) is one of the straight mineral oils -
meaning no additives like those found in the after-break-in oil, such as
Shell 50-100 multigrade or the like.

Be careful out there, use the wrong oil in your aircraft engine and you will
pay, one way or the other!
