Moin, as soon as the Assyst is due, I wanted to buy the oil and the oil filter myself in advance. Mercedes is clearly too expensive for me. Which oil & which oil filter would you recommend? I don’t know about it. I only read that 5.5 liters have to go in. It is a 200K m. Automatic R171. BJ 07. Where to buy the stuff best. Always read something of release 229.51. Have here still oil for my E220 CDI which has the same release. Is a Shell Helix Ultra AX 5W-30. Can I use the a Take it?
