Motor oil T-Roc 1.5 TSI petrol

I have my T-Roc now almost 1 year and this morning came to me the message that I should check the oil level. I did it immediately. Since I was overwhelmed in the situation early in the morning, I asked an employee from the gas station to refill oil. I’m just not sure if it’s normal to have to refill oil now. It’s about 16000 km down. How are your experiences? And what oil can you recommend for the T-Roc 1.5 TSI petrol?
