I have a 2017 Challenger R/T Shaker with the 5.7 hemi. Bought the car with 40,000 miles and a fresh oil change. I changed it again at 47,000. It is now coming up on 54,000, and the oil life gauge shows 37%.
Should I stick to the 7,000 mile interval, or wait a bit longer until the oil life gauge goes down?
