So if the don't take into account the quality of the oil then its just mumbo jumbo designed to get you to over service and spend more money

The diesel that we are talking about can only run synthetic oil and should run somewhere between 5000 and 10000 miles depending on use.
Even full synthetic oil breaks down faster in higher heat conditions. Jeep acknowledged the problem and has published a fix that very well looks to be producing the correct results.
There is no way for a vehicle to do a "quality analysis" so I am not sure what you are expecting it to tell you. Someone who drives there vehicle very short distances then allows it to sit for long periods of time will need to change their oil more often then someone who drives strictly on the highway. The system is about lengthening the time between oil changes more than anything.
Edit: My apologies, I just logged onto my PC and I can see you are Aussie. I disagreed with how they lowered your oil change intervals there... the conversation here is slightly different though. The vehicle is designed to go up to 10,000 miles between oil changes (16100.00km) or one year in optimal conditions.
