When my Mercedes was new, the oil changes came free for the first 50k miles. Factory spec was Mobil 1 and every free service I got was itemized with dino oil instead. Service mgr said it was all the factory would pay for. Car is now 14 years old, gets oil changed once a year and engine runs like new.
