I plan on changing to synthetic at 5000 miles, Mobile 1 5W30. Reason is, I don't think the engines get fully broken in at 1200. Until then, it's Pennzoil 5W30 mineral based. I also change at 500-800 miles, then again at the 3500 recommended. Probably unnecessary but just in case there is some build-up of shavings etc from factory/during break-in.
