Any decent brand of 10W 40 semi synth will do the job.

10W40 that meets either 229.1 or 229.3 spec should be fine.

FUCHS Titan XTR 10W40 or Millers Oils XSS 10W40 both meet MB 229.1 as Ollie recommends Change your oil once a year based on your motoring history. Fully synthetic "thinner" oils apart from their extra cost are not necessary on these older engines and tend to show up worn seals a bit more.
