Metal specs in oil filter

[Elliot Cannon]

I would use a magnet to see if there is any ferrous metal in the oil. Get a strong magnet and rub it all over where the flakes are. Then I would just wait to hear what the oil analysis says. I change the oil in my Cessna 150 every 25 hours and always run a small diameter magnet between the folds of the filter.

Cheers, Elliot

so in a somewhat related question .... would the IMS bearing starting to degrade be ferrous or nonferrous ? and it is distinguishable from bearing merial ?

I will be doing same exercise as OP in the coming weeks.

The IMS is predominantly ferrous.

There are non-ferrous bushings but not many non-ferrous bearings.
