I've been using one of the newer style Purflux oil filters on my 300 SEL for the past 1800 miles and it seems to be doing a great job - the oil has changed color.

This alone shows me it is doing well considering the stuff that came out of there looked like - it was as black as the Hengst oil filter that was on the car and the filter had a date/mileage written on it that was basically 2 years & 17,000 miles (previous owner not me!)

Anyway, this new Purflux looks to have some really decent filter media in it as seen in Gilly's photo:

It doesn't look to be any cheapo, that curve pleat design w/ metal endcaps looks pretty nice.
