My dealer recommended that I change the motoroel after the start-up phase. According to his announcement, this makes sense after 2,500 kilometers. Is this really useful or is it just an attempt to use the workshop and take money? Did your dealer also point out to you when picking up a vehicle? I found nothing in the on-board book on the subject. Environmental pollution caused by Altoel (disposal etc.) if senseless unnecessary oil changes would have to be carried out then disk If 8 out of 10 new car owners let this be done, a lot of “altoel” comes together, which would actually be perfectly fine… In my opinion, an oil change in today’s new cars should not be necessary anymore, or do you actually have advantages? An extremely low oil consumption over the entire life of the vehicle perhaps? Or a longer life of the engine? Your opinion and experience in addition?
