In all my vehicles (two, three and four wheeled) I run Shell ROTELLA T6. And it goes on sale all the time.
That being said, I do a "flush", "rinse" or "washing" with Marvel's mystery oil about 10 to 50 miles before I changed the oil. And between the two I've never seen any real build up of carbon/oil burn anywhere.
