Purolator Pure One for me. Frams are always bashed on, but I have used the on my daily driver since new with mobil1 w/o any trouble. It has 195k on it and oil was change every 8000 -10000 miles. It still uses less than a quart between oil changes (8 -10k) which seems acceptible. I now use pure one's and the oil seems to look clean longer. Oh, I like the vacuum operated oil sending unit.
