As promised, I would post my impressions of the new Purflux oil filter for the 300E. With the new oil filter, it pressurizes almost instanteously very quickly whether it is cold or hot compared to the delayed times of the older oil filters. THe only drawbacks I can think of, is the $17 price and it is a bit difficult to screw on by hand compared to the previous filters. I wonder when fastlane will bring this part so I won't have to pay extra for a hologram. Also, the oil pressure never dipped below 2 after a spirited 2 hr. drive.
