Changed my oil today. 2005 C2S with about 80000 miles. Been using DT40 for a few years. About 3300 miles (1.5 years; car was laid up about a year) on this oil change. Opened the oil filter case to inspect the oil filter medium. Saw a lot of fine black (oil soaked, of course) powder in the creases of the filter medium. Non-ferrous (wouldn't stick to magnet, other than due to oil acting as "adhesive"). More than I've seen in the past. I've attached two pics here. What do you think? Source? Cause for alarm? Needs immediate diagnosis/correction?
