Duly noted. However, upon further research, MB recommends Mobil 1 0w-30 which now carries the next level cert., being 229.52.
They state; "MB 229.52 Oils meeting this specifications must have lower ash content, at least 1% better fuel economy compared to the requirements of MB 229.31 and MB 229.51 and better oxidation stability for biofuel compatibility. Can also be used where an MB 229.31 or an MB 229.51 oil is required. Just like MB 229.5 and MB 229.51 this spec requires a long life oil."
I like this oil better for these reasons: 1. lower ash content. 2. better when biofuel is used(sometimes you can't avoid buying that crap) 3. better fuel economy, even if only by 1%.
Remember when life was easier!
