How much 5W-30 oil per 1000 miles was your 200,000 mile Subaru using? "Any 5W-30 will be fine for the 370Z engine"?!!! What???!!!! Anyone reading this: DO NOT USE 100% PETROLEUM BASED GROUP II OIL IN THE 370Z ENGINE!!! This thread is making me tired and pissed. "Ignorance is Bliss." Later...

And just what are your qualifications.

...just make sure you put in the correct W oil for your driving conditions (for most, that would be 5W30), make sure it has API certification, and change it regularly at 3K to 5K mile intervals and you will be fine no matter what you brand or type (non-synthetic, synthetic, or synthetic blend) you choose.
