Check my signature for oil analysis info on my 07. The engine sheds a lot of metals when breaking in, so changing the oil early the 1st few changes is a good idea. But, after that, the Mobil 1 0W-40 clearly shows through my oil analysis that it can last the 13K miles that MB recommends, and that is even running E85 fuel.

My C300 owner's manual doesn't list the oil spec and refers to the Factory Approved Service Products pamphlet, which of course is not provided in the new owner's literature packet. Looks like a Catch22 situation: use the proper oil to maintain your warranty, but we won't tell you what the right oil is.
The consensus in this thread is pretty evenly split between 5w-40 and 0w-40, and it appears that different service departments have different opinions as to which grade to use. Does it really make a difference?
Why is such a simple and basic thing like the proper oil weight for the C300's such a mystery and closely guarded secret?
I repeat the question asked at the start of this thread:
Are we to use Mobile 1, 0w40 in the C300s and C350s?
Thanks

For me, 0w40 is the intended choice and what I believe is in the car from factory. I guess I won't have a choice was the dealer puts, but if it was me, I'd use 0w40.

How can they not give you this information in the owners manual?
Its odd, looking at that website, under the MB 229.5 section - that both a Mobil 1 0W40 and a Valvoline 20W50 are approved.
There is alot of talk on Porsche boards that the Mobil 1 0W40 is too thin, because few owners face the ultra-cold ambient temperatures to justify it. And posters wonder whether running that oil might contribute to seal leaks and oil burning.
Castrol makes Syntec 5W50, which has a very wide range. Castrol's 229.5 blend is 0W30, but unless you lived in a frigid climate, you have to wonder what would be wrong with using their 5W50.
All that said, the Mobil 1 0W40 is the safest bet I imagine.

MB spec 229.51 for the Bluetec diesels calls for the MB-specific 5w40 made by Mobil 1. I ran it in my w202 for the past 2 years. Has excellent detergent properties. You don't need a 0wXX oil unless you live in the arctic circle. The MB 5w40 will keep your internals as clean as a surgical tool

Yeah I agree a 0 weight bottom is probably silly for the U.S. Maybe MB should change this. It's very hot where I am. Again, I don't get to choose the oil though cause its whatever the dealer uses.

ok children (j/k) i love little arguments like these:
From the horse's mouth (actually this is from the Factory Approved Service Products Booklet that you should have got with the other owner's manuals)

One thing about that chart confuses me, and that is the Mobil 1 Formula M that is 229.5. I have known about 0w-40 229.5 and the 5w-40 ESP 229.51, but this third one is new to me, and I cannot find any information, or even mention of it anywhere but on that table.

It also seems that MB is not keeping this current. The info has not been updated in three years! Yet, we have heard from several sources that use of 229.51 has been expanded by MB to include gasoline engines (except AMG). Also they refer to Mercedes Maintenance System. I think they are referencing the variable service interval system--something which is no longer used in the USA. We now have the fixed (13K) recommended oil-change intervals. The owners' area of their website is of no help either.

MB's website is so behind in the times. The international website and other country's MB sites all look bright, clean, and up-to-date. The MBUSA site looks dark and dreary and out of date. The content on it is pretty good (love the fact that you can look back 16 years and look at the specs/options/etc. of each model).

I'm now convinced that 0w-40 is the right oil weight for th C300.
Thanks to all who responded.

Here you go Guys. I know it's a couple of days since the last post but I have been waiting for these from MB customer services. Hopefully you should be able to get a definitive answer to your question's regarding which is the correct oil.
