Which oil at Omega B (BJ2000)(Facelift) 2.2Liter 16V

Hello, I would like to make an oil change now next week. Only which oil is advisable or recommended? a 0W30 or 5W40 or 10W40 ???? The demand of the car is normal, i.e. city traffic and highway is regularly driven! Will the Omi Facelift renew the oil drain screw? (because of the sealing ring which is attached to it) I thank you now for the answers! mfg Omega73
