What's the best oil (weight, viscosity, brand, etc.) for W210 E55 in Northern California?

I'm thinking of giving Mobil 1 5W-30. Is this good?

Mug

I would go with the factory fill which is Mobil 1 0w-40. Down here in Orange County, the local Autozone's carry it. If you can't find it there, try Pep-Boys or some other auto supply place. If you still can't find it, try a MB or Porsche dealer. IIRC, only Mobil 1 0w-40 and 20w-50 meet some special MB spec.

E-Klasse

Check out AMSOil.

Just want to share in case ppl want to know as well.... found a pretty good website that shows the list of engine oil recommended for mercs....

BTW, I just realized that FRAM oil filter is manufactured by MANN, which I think is MB OEM supplier.

Anyone knows this?

Darn.... I still couldn't figure out how to open the AMG cover to check/replace air filters..... can someone please help me?

Deception

I would run synthetic 0W-40 or 5W-40 in your E55. 5W-30 is not recommended (as shown on the link you posted) because it's simply too thin at operating temperature. You'll want the protection of a 40-weight. Since you're in California, you don't have to worry about sub-zero starts so 0W and 5W would make negligible difference.

Mann is indeed an OEM supplier for various European makes, but I don't know if they really do make Fram filters. If in doubt, get the OEM Mercedes oil filters.

As for taking off AMG engine covers, look for some bolts.

That's what I'm using in my '98 E430. Changed once per year, with an oil filter swap in the middle at 6 months.

Using AMSOil and that schedule is the best way to do it. Good thing the filter is easy to change too.

Best? German Castrol Syntec 0w-30 from AutoZone.
