Hello,

What a great resource you have here. I am excited to dive into the knowledge that is available within this forum! I just bought my first Cadillac, 2012 CTS4 wagon and I am eager to learn more about the car and how to take care of it. I have a few immediate questions that maybe you can help me with. I am interested in a build sheet to learn what the car came with from the factory; VIN is 1G6DM8E33C0154555. Could someone point me in the correct direction for this? Lastly, I am interested in learning which engine oil viscosity is preferred and if you prefer conventional or synthetic?

I may be asking too much in one thread; I apologize in advance.

Regards
