 I would say that would be 5,000 miles on the average car. There's some Euro cars and some other vehicles that can go much longer than that. Some cars that are pre-2015, especially if they're running non-full synthetic, may go less than that. But don't wait for that reminder light to come on. I just love that oil sticker. That's what does the trick. Use the reminder light as a backup system. So make sure it's reset every time the oil's changed. Right.
