way ahead of you, im just mentioning the toyota factory service interval
I thought the same thing, admittedly I didn't track mine, so I kept checking the oil at 1000km intervals expecting it to be black and gross but it was still mint at 14k. Plus I wasn't sure if the oil from the factory had any sort of running in additive in it...
