Seat Altea XL 1.4 TSI => Oil change after 1,000 KM?

Hello, I have a question about the general understanding: We recently added a new Seat Altea XL, 1.4 TSI with 92 KW for the lady of the house. The seller knew that it would be useful to carry out an oil change after about 1,000 KM. This would remove abrasion parts from the engine circuit and significantly reduce consumption. The vehicle currently consumes about 9.5 -10 liters… Another argument of the friendly was the uncertainty whether the SEAT plant could be sold all people with expertise surveyed so far have shaken their heads with these statements, what is the value of experience about the meaning and nonsense of this measure here in the forum?
