On that basis it should have had an oil service every two years as a minimum. If you get it I’d put it through an inspection 2 as it’s at 13-16 years old. Mine does a couple of k per year so very similar usage. I have oil service every 2 years and inspection 2 every 8 years. So basically I have an inspection 2 service every 16k ish which is just over the mileage between one service interval.
