I need to do the first oil change in my Hyundai EGT n-line. It has the 1.6 turbo engine with GDI. I see that Hyundai recommends synthetic 5W40. Suggestions? Someone told me Motul, but then I saw that may not be good for GDI.

I'd say use just about any affordable synthetic and change it every 3k miles like the manual says for severe service, expensive oils for extended drain intervals are pointless in Hyundai GDI engines because the primary reason why you have to change the oil so often is fuel dilution and soot contamination so it doesn't matter what oil you use the engine's gonna fill it full of soot and fuel and you're gonna have to change.

Mobil 1 0W-40 is a solid oil for cheap ($22-23/5L at walmart). What are the oil specs the manual calls for specifically?

Castrol Edge 5w40 is a stout oil as well.

But that lacks gasoline engine approval might be problematic if the OP has any problems under warranty.

Yes the Rotella T6 0W-40 is SN rated....but also a unicorn....I have never even seen it in the 'flesh'
T6 5W-40 is not gasoline engine approved.
