I've heard that the newer cars do not have to have oil changed as often. on 2009 Nissan Altima

I'm careful about changing the oil and want to be sure the old guidelines no longer apply???

Also, I can't figure out from the instructions in the book how to turn off the lights above the windshield. The book shows 3 switches and only explains about 2?????

if your car is using synthetic oil you should change every 10000 km if your using regular oil every 5000 km sorry I live in canada so those are metric #
