johnr Posted May 20, 2016 Report Share Posted May 20, 2016 Hi all CTsw owners, I am attaching a copy of an email I sent to Flight Design over 1 year ago. I never got a reply. I had an oil sample checked by a specialist laboratory & found that the oil was contaminated with sand. Has anyone else had oil tested & discovered that the oil was contaminated? sand in oil.rtf Link to comment Share on other sites More sharing options...
