Yes, but wasn't a ton, was the cleaning of a dirt engine (a little varnish/carbon from dino oil) and 20 grams of powdered graphite. Went to by passing only when the oil was cold, at 1st startup of the day, could hear a quick rattle. But, when warm was filtering really fine, since the container with the oil is several months sitting in the garage and the bottom is normal, a little very fine material carpet as usual.
