				Here is an article on Aircraft Engine Oil change intervals.
  http://generalaviationnews.com/2004/12/24/the-no-1-question-of-oil-experts-how-often-should-oil-be-changed/
      
      Lycoming recommends 25-hours with a screen and 50-hours with a spin     on filter or a maximum of 4-months between changes.
      
      My experience with my GMC that I was only driving about 100 mile per     month over a 3-year period, had the valves start making noise when     it was cold.  Oil changed fixed the problem.  This is an example of     where oil change based on time interval is needed.  Does it apply to     aircraft engines?
      
      I recommend following the manufacturers recommendation on oil     changes.  Oil and filter is a small cost compared to the cost of the     engine or engine work.  If we are having a hard time paying for oil     and filter every 4 months, it is time to get rid of the airplane as     it calls into question if we should be flying an aircraft we own at     all

      [quote]                     Thanks for all the replies, I           anticipated the answer, but then again, maybe?  I have been           doing most of it, then my A&P finishes with me and does           the logs. Now, re oil change with so little time.(thinking 100           hr comparison) What advise there? I am thinking change oil but           not filter, or would you advise, not even changing oil? Thanks           in advance, Charlie Heathco
