Congrats on your purchase! I came to this site several months ago asking the same question, assuming someone would just say "buy brand X." Instead I found endless pages of info and debate on the subject. In short, my head exploded!
For starters, do a search on "ZDDP"
Maybe a search for "synthetic"
and "motor oil recommendations"
Oh... here's one:

Get your reading glasses.
Just use your imagination on searches.
SPOILER ALERT!
(there is no consensus)
In the end I ended up buying brad penn 15-40 based on my driving. I'm not saying it's better. It's what I ended up with after being completely overwhelmed on the subject.
Good Luck,
Ron
