04 saturn ion 2.2 ecotec. I bought it with 106k and she has run perfectly, she now has 154K I have always done oil changes around 5k. This last change I put in QS full syn (free after rebate) and an stp cartridge filter. So what say ye all about how long I should run this oil? My oil life monitor always says around 6500 miles. I will NOT do a UOA and never have because I have never had an engine die on me (except my 88 Pulsar many years ago). Just curious what everyone recommends. And I will probably not follow your reccomendation anyways
