I have a 2007 Chevy Impala and after you reach 0% of life remaining of the oil, how many miles can you go pass that before you have the oil changed. My husband says 200 miles, but I'm concerned about it now. It has been 5 days since that indicator light keeps coming on "change oil soon". In the old days when the oil light came on that meant you needed to change the oil that day. I would appreciate it if someone could answer my question. Thank you! Jo
