I will be doing an oil change on my '09 Nissan 370Z this morning. I did the first change at 1200 miles and used the expensive ($12.99 per qt. plus tax) Nissan ester oil and a Mobil 1 M110 filter which is slightly larger than the standard size filter. The car just turned over to 5,000 miles, I pulled the drain plug last night and have some Redline 5W30 and another Mobil 1 filter ready to go. There has been a lot of discussion on this site and others regarding the VQ37 engine and the high oil temperatures that seem to go hand in hand with the design so I think Redline will be a sound choice. I don't plan on OCI's past 5K miles though, figuring this engine, Sou.Cal temperatures and frequent stop and go traffic will be hard on any oil. The Redline was only about $9.95 per quart delivered so it's more than $25 cheaper per oil change than the Nissan ester which isn't recommended for long OCI's anyway. I'll try the Pure 1 filter next time if I can find one, the Mobil 1 filters are expensive, running about $12.99 each.
