Did the 2018 GT's come filled with MC Blend or Full Synthetic?

Changing the oil myself tomorrow at 1k just for piece of mind- I just want to be sure the oil from the factory is the M.C. synthetic blend so I can just replace it with one more round of blend before going full synthetic after 5k miles.

I don't want to put blend in there now if it already came with full synthetic.

Synthetic blend from the factory.

Synthetic Blend MC 5w-20. I changed mine at 27xx miles to Pennzoil Platinum Ultra 5w-20 using the MC FL500s filter. Havent heard any engine ticks or funky sounds for the 2000 miles after the oil change.
