Amsoil is a IV oil and great for everyday use. It exceeds most oils out there and will do well for extended drain intervals. You can learn more then you want about oils at bobistheoilguy. They are the major forum for oil related issues. Most on the forum like Amsoil and it tests very well in engine analysis. German Castrol is also highly regarded. I think a great oil is a must but will not stop the over heating issues associated with the 370Z. Good oil will however, help lubricate as the temps rise to the high levels that are experienced. It is not always prudent to go to a thicker oil as a thicker oil may not penetrate into spaces that are needed as well as a thinner oil. Again, this is not a simple subject and requires much study into the components of an oil and its' uses on a specific engine.
