I may not buy another WIX after my last oil change (although I did replace one WIX with another). My wife's '02 2.7 has about 68,000 miles. I replaced the filter and oil and a couple of days later the oil light was flickering at idle. I replaced the sending unit which did not fix it so I did the filter again. No more light and it's been almost a month. I'm not sure what I'll buy next, though.
