I just purchased a new 2023 Kia Telluride in March. I dumped the initial oil fill at 1187km to get rid of the break-in swarf, and sent a sample in for analysis. I wanted to see if this initial factory oil had anything special in it that indicated that it needed to be in the engine for a normal run (supposed to be 6000km/6mths) to break-in. I always dump the initial fill on a new car early like this to get rid of the swarf, and have never had any problems with engine using oil afterwards, FWIW. Anyway, just thought I'd post the results for anybody that's interested.
