I had my second oil change at three years and about 7000 miles. The dealer padded it somewhat with things like gas treatment, oil treatment, engine treatment, and cabin air refreshener (after I specifically asked for no fragrance) air cabin filter replacement, and I think brake fluid flush, treating it as a three-year service even though it was my second oil change, with low mileage. Now it's over four years, about 15 months and 3000 miles since the last servicing, and I'm out of warranty, but it will be mine third oil change. I will have to prevent them from doing those things again or other things that it doesn't need with such low mileage.
