video or blog on oil filter medium inspection
It would be nice to compare a persons filter medium with examples of acceptable and not , filter medium pictures. It could be combined with the magnetic plug inspection possibly.
I am working on the 25 hr inspection for a new 912 uls , I expect a little more metal in the filter medium and on the magnetic plug than a typical 50 hr oil change but with nothing to reference than the max rotax specs its difficult to determine what is in the acceptable range and if there should be a concern.
