Just for reference I might be a little jaded on the topic as I used "10k" oil in my 1999 intrepid. The oil sludged and caused the guides to wear and basically blew up the engine. Since then I tend to be a little gun-shy on oil changes. A trusted mechanic told me once that if you're in it for the long game don't mess with regular maintenance and always do the oil/fluids before mfg recommended as they're not in it for the long game. They're in it to sell you another vehicle. (Hence why they have service centers connected to showrooms)
