How many use the oil change indicator in the driver information system rather than just changing every 3000 to 5000 miles, like I did with every other car I owned? I bought my 04 GT2 in June. I changed the oil and filter again in September, but the display still reads 7% Oil life left. The fuel information changes with each fuel fill-up so I assumed the oil info would change, but it didn't. How do I get the Driver Information System to reflect the oil and filter change?
