I would change it every 24 months if it does not start to sludge before. Just check the oil˙s condition every few months and you`re on the safe side, Mazdas have great engines, that engine can go for a 100 years with that annual mileage:>

A friend of mine has a newer Opel with an 18000 mile oil change interval and 95% of that car`s journey are cold starts and less than 3 miles of driving. He forgot about changing oil and drove over 20000 miles with one oil. The oil did smell of gasoline, but was didn˙t even look that bad and the there was hardly any sludge. Good synthetic oils can go for a very long time.
