I believe all the maintenance intervals are a multiple of 3000 miles. I completely agree with Bernie about their importance, though the manual also states: "Under no circumstances should oil change intervals exceed 6,000 miles (10 000 km) or 6 months, whichever comes first."
If you want to get back on track, I think you could safely wait until 24,000 without risking your warranty since that would only be 4500 miles. Or, if that bothers you, do one at 21,750 and then get back on track at 24,000. Do
pay attention to the 3-month recommended and 6-month maximum intervals, if you average under 1,000 miles a month.
I'm half-way to my third change now because of the time interval rather than the mileage, at 3300 miles. I intend to switch to fully synthetic at my fourth change. I'll change it at close to the six-month intervals, thereafter.
