What exactly does "still on max" mean? Are you talking about oil level?
Oil changes are required because the oil wears out eventually. Synthetics last much longer than mineral. The Crossfire has a computer system which calculates when you need to change your oil based on temperature, driving style and time. Depending on your driving habits, a wrench icon with either an "A", "B" or clock icon will appear when an oil change is required as determined by the system.
A and B refer to the A or B maintenance schedules, basically highway or start-stop driving. Clock icon means time-based.
You can manually check the remaining mileage for an oil change by turning your ignition to the ON position, waiting for a little clock icon to appear, then push the trip meter reset stem twice quickly. A number will appear showing you the recommended distance remaining to your next oil change.
The system is set at the factory for 7,500 miles or a timed period or combination of both. UK settings might vary due to EU environmental rules.
Most Americans have a habit of just changing their oil at 3,000 mile intervals, not really necessary with synthetics.
