There's an oil life monitor, so you don't get any mileage intervals directly. You do get some guidance for when to expect a message.

What isn't clear is what the owner manual means by 'load'. I would consider track or dragstrip driving to constitute "maximum load" driving even though the car would be empty other than the driver and perhaps a track day instructor.
