I'm an oil nerd. I admit it. Considering moving to a C3 / LL-04 oil to limit additives the phosphorous build-up in my cats (I burn about a quart every 2-2,500k). These are all U.S. available options. A few standout (Ravenol HLS, Mobil 1 ESP, INEO Long Life). Also really like Pennzoil Platinum Euro L because of its GTL base (and on the shelf at Walmart).

BTW, I am on a 5k OCI, so not worried about the low TBNs and U.S. gasoline (which is trending in the right direction).
