So tomorrow I want to change the engine oil and filter at our D26 440hp. How much engine oil should be filled in so that the display does not continuously show too much broth? And if I still change the diesel filter, should I then use the hand pump 100 times pumps like it should be normal with Actros? I’m too lazy to look into the manual. If relevant is Bj 2005, has still Pritarder and HydroDrive. Thanks in advance!
