Don't get completely mad. The Aurion pushes out 204kW when run on premium unleaded, so there's something to stand by. None at all (taken by me). LOL. My car had quite a story behind it (see 'My Aurion is now on the road' and 'DJKOR's Aurion' for more info). I didn't buy it new. It did live several months though in sunny Cairns where the temperature wouldn't fluctuate too much meaning the engine didn't have a lot of hot/cold cycles. I'm sure that would have been a plus in some form. I would say that it had a good mix of gentle driving by older people, and the occasional thrashing by someone who was lucky enough to hire it. Anyways, it is stated by Toyota that there is no specific break-in period. The engine doesn't require it. As a general guideline, just run the car easy for the first 1000-5000km. hehe... being "mad" maybe an over exaggeration :P Ah ic ic... just not sure whether I should hit the 6000rpm during the "break-in" period. The manual did say that for the first 1000k, should drive gently.... not exactly sure what that means.... does that mean accerlate gently but not hitting the high rpms? There are so many different views out there.
