This is my third oil analysis in the past three years on my Pa28 1970 Cherokee 14C.she is at 1740 hours and just had her annual. The mechanic said the filter was clear but when she went for oil analysis this is the first time she came back with elevated levels of Iron (111), Nickle (7.7), Aluminum (49) and Silicon (16). The first two years I flew her approximately 100 hours and this past only 57.
I don't know if I solid be concerned.......
