I have the same confidence in the Nissan engine, my 355 SBC, '03 Sport Trac and John Deere LT150. All use Mobil 1 and the oil is changed once a year irregardless of the mileage. But that's just me and my 35+ years doing my own maintenance and repairs. Hey, why pay $100/hr labour rates when you can DIY?

We put enough miles on the Z that I am changing it every 6-7 months on average. The dealer did the first two cause I had some credit with their service department, but going forward, I will be doing them myself. I will say that if you do the recommended 7500 miles or 12 month increments, I think that the cost per year for oil changes just isn't significant, even if you do pay someone else to do it. We ARE driving $30K vehicles after all, so if you don't want to do it yourself, then pay the money to have it done right. I, for one, am looking forward to doing my own maintenance on the Z. It is my first true sports car and really the first car I haven't thought of as simply a mode of transportation.
