Purchase of a new i20 BJ 2013 / Motoroelwechsel if older than one year

Hi dear Hyundai connoisseurs, We are just on vacation in Poland and with a local Hyundai connoisseur one has found a new i20, BJ 2013, at a good price, which we would like to have seen as a second car with us. The problem, the car is BJ 2013, and is still with the first motoroel, though never run. The Haendler says that no motoroel change is necessary! And I can drive quietly so? My humble knowledge, however, tells me that Motoroel, what is older than a year, MUSS wec Well, the contractor doesn’t want to hear any of this unless I ask for it at my own expense. I contacted Hyundai Motor Poland by telephone and was simply informed by the Damme’s answer. My question has been answered by repeated, innocuous phrases that the contractors have exact instructions??? What do you think? Must the motoroel, which is older than a year, be changed, and at what cost must be at what cost? s this be done? Thank you for all the competent answers. dt
