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
