Engine oil Mobil or ZIC

I personally use full synthetic Mobile 1 usually.

mobile 1 is a good brand. id go with it

Why not just buy the Mobil 1 and take it to the dealer?

My 2925 Passat is happy on the Mobil 1 esp synthetic.

I was running Mobil 1 for many years in my 14 ST3 and started with Mobil 1 in my now 16 ST3 but this year I swapped to Walmart brand full synthetic and haven't had a single issue except for extra cash in my wallet. It meets all the specs and I change it every 5 thousand miles regardless of how the car is driven. I'm at 86 k now on the odometer and she still pulls string like the day I picked her up.

I have never seen my 2017 Jetta low on the dip stick. I usually change it about every 5k miles using Mobil 1.

I've personally run Mobile 1 full synthetic for 10k intervals ever since the factory oil changes ran out without issues.

Not saying it is better than anything else, but on my G60 turbo i used Mobile1 FS-X 5w-50 and will continue with this oil on my PG/ABA turbo.

I use Mobil 1 for engine oil, and Honda stuff for transmission fluid.

I was using Mobil 1 fully synth 5w40 on my old cab with no problem at all. good pressure at idle and at 2k. I used this oil in my new cab (same engine) and boom! No oil pressure at for the first 15 secs. Then it immediately jumped to 5 bars and finally settled down to 1 bat maybe less. However, I saw a dramatic increase in oil pressure even with the 5W40 mobil 1 when I switched to a 2L oil pump. Idle pressure was arround 2bars. Although I used it last summer and it worked just fine throught my vacations in Greece.
