2016 GMC Canyon - Which oil?

I’ll have to check my oil caps now to see if they have the little “i” on them. Oh for the days when things were labeled with words instead of unrecognizable symbols-like washer, wiper, lights, fog lights. I still can’t figure out the little little symbols for the window switch and the lock/unlock symbol. Ah a new business idea-making stick on labels for all these symbols.
