A Nissan VQ engine isn't going to blow up within 80k miles. If driven hard enough, though, incremental wear can occur. That's the concern. And if it makes you feel better, keep a record of maintenance. Realize, said records don't need to be legal documents, just some notes you make in a notebook. And you are allowed to change your own oil. You don't need proof of what oil was used for every oil change.
