General rule of thumb that oil should be changed every 12 months, or every 5000 miles, synthetic can be pushed to a higher mileage (7-10K) but with turbos and with the amount of heat they generate, you don't really want to do that.From the manual.......MAINTENANCE PLAN At Every Oil Change Interval As Indicated By Oil Change Indicator System● Change the oil and filter.......... Have a link for your info?
I really pushed both the time and mileage between oil changes in my '15 charger a few times and it sat a lot during the pandemic. It had an oil life indicator too, but I don't think I ever saw the indicator get close to zero or even low. I'm not sure what that thing measures, but I'm not going to trust it.
If you want more resources on it, just look up the life of synthetic oil. The manual for our car says to absolutely be sure to change it BEFORE 10k, so I'd say as long as you're changing it between 5-9k you're doing fine. I just err on the side of caution.
