How long do I have to change the oil when it says there's 10% life left?

Seriously , How long do you want the engine to last? That damned 'maintenance minder' thing is annoying!! They are designed to go longer between services , but you are supposed to check and MAINTAIN the OIL LEVEL , between services. Maximum miles I would go , is 7,500 TOTAL between oil changes. I have had customers come in and the display shows '1964 miles past due' , those are the ones with a much more 'elaborate' service history! usually NOT covered by warranty due to problems caused by 'neglect'.
