The Mitsu filters are probably made by some yippenese company over there. I've never had an issue on any vehicle with a NAPA Gold (WIX) filter. The oil weight is specced on a chart in the manual, based on temperature. Here in north GA, I run 5W40 Mobil 1 in mine with 208k on the clock. No tick except for when it's needin a change. <img src="/forums/images/graemlins/kewl.gif" alt="" />
