Hello everyone, this is my first post, and since the topic is which is the best oil I thought I would throw in this link. I came over here from the Z forums as I hope to be a future Camaro owner. I pulled this link from My350Z.com; which is very informative as to which oil is best for your motor. Obviously it is geared toward the VQ motor, but read through this thread and it can guide you in the right direction as to which Oil will be best for the LS3.
