My 16 April 2013 300c SRT8 has just displayed a message saying the oil needs changing. Is this message based on kilometres? or the date? I have done 18,000 kms. Should I get it serviced now or wait until the 24,000 kms?
The oil changing interval is dependent on your driving style. If you drive many short trips, the changing frequency will have to be more often. A diesel model, as the one I have, has a nominated interval at 20.000 km or 12.500 miles. But the engine also has 9,5 l or 2,5 gallons of oil for a 3.000 cc/ 180 cui engine. I use Castrol Edge 5W-40 full synthetic.
