From what I've seen after visiting a few (mostly Santa fe Sport [2013-present] and Sonata [2011-present] forums over the past few weeks, oil type does not matter. Noack %, Synthetic vs Conventional, OCI, catch cans, fuel octane, driving style, ambient temps, nice looking UOA... nothing makes a definitive difference. Some folks using full synthetic get deposits early and some using Conventional haven't had any issues yet, and vice versa. Most of these are around 50-80K miles (this is typically when symptoms begin to show, like hard starts, knocking, pinging, vibration under acceleration and stumbling at low RPM). But nailing down who gets it based on oil used seems fruitless since dino, blend and syns get it, and dino, blends and syns....don't.
Now to be clear, most on those boards have not had any carbon issue regardless of the paranoia they exhibit. I am referencing those who have posted that they have, which is a decent amount of folks.
