I've got one of my Miatas running Royal Purple on 3000 mile/6 month intervals. Rather than take generic advice, though, I'd advise you to send oil samples out for analysis (it's about $25) once a year or so and actually know whether you could have gone longer, shouldn't have gone as long, or got the change interval about right- and it'll be a good guide to the health of your engine.
