I have a 2016 300 with the Pentastar V6 (which I love, by the way). My question is this: conventional wisdom says oil should be changed every 3000 miles. But at 3000 miles, the instrument panel says I have over 60% oil life remaining. I've been changing every 3000 or so, simply because that's what everyone says. I don't want to risk damaging the engine, but neither do I want to spend money on unnecessary oil changes. Anyone have any thoughts?
