Changed the oil and oil filter.
I have a magnetic oil plug and it has very small 'fur' kind of black material on the magnet as you can see on the first image. Is this normal or should I be concerned?
The plug's magnet cleaned off real shiny just by lightly wiping it with a towel.
Another image shows the cut out filter that is real clean. Thre was only one very small peace of black plastic kind of material - approximately a size of 0.5 x 0.5 mm.
