I'm going to have the oil changed early, at just over 2,000 miles, and I can't find a listing for the recommended oil weight.
There is a Mobil One recommended sticker on the car, but no indication of the weight. Both 0W-40 and 5W-50 are on the MB approved list, but I'm not sure which one is in the car now.
Anyone know which one is correct for the US build C300? Thanks.

Stan. The car comes filled with a narrower spectrum Shell running in oil which should not be changed early.
After run in as Vic says only 229.5 approved products should be used. 0W-40 or 5W-40 are OK from the approved products listing. 0W-40 being the preferred for global use where large temperature swings have to be accommodated. On no account allow 229.51 products to be used. They are low SAPS products for diesel passenger car with Cat & particulate filter. They will not adequately protect the valve train in gasoline engines.
Here is the latest listing of approved products for your engine.

Stan - do you find you are using the amount of oil mentioned in the manual? It says depending on your driving style or when the vehicle is new it may use up to .9 Qt per 600 miles.

I haven't seen any oil usage in the first 2,000 miles.

No. Leave it in there until the first scheduled service. Changing to a 229.5 synthetic can severely retard/prevent proper bed in of the engine. Listen to Benz. They have done all the homework. I've been working with them on & off regarding lubrication for most of my long oilco career.

Some initial oil consumption is absolutely nothing to worry about. An initial puff of oil smoke from the exhaust after standing overnight that clears immediately is equally nothing to worry about during run in/break in.

According to Mobil, the car comes with Mobil One from the factory.

That happens to be crap or out of date unless the Tuscaloosa plant is doing something different to ROW. I'd like to see an oil sample analysed to prove my point.
It should be noted that the Mobil claim only applies to AMG models. AMG has different requirements for viscometrics & HTHS (High Temperature High Shear).
Benz uses chamfered MOS2 coated rings running in an Alusil bore. This is a difficult break-in regime but highly durable.
Mobil 1 Euro Formulation 229.5 (not all Mobil 1's) is a damn good product. I'm in no way knocking the product. Early change of the intitial fill product can lead to having oil consumption issues in the long run. Just listen to Benz & don't change early. If an early change was desired they would tell you. Their filtration is excellent.
BTW ~ the break-in product is also a synthetic.

Not true ~ take a sample of the oil from a new car out of Bremen or Sindelfingen & have it analysed. You will find I am right and you are wrong. But you love to argue & know better than Benz. Go back to the 204 forum & you will find it covered there as well. Do you ever bother to read people's profiles?

As you can see the M274 is a slightly less critical engine than others. The use of 229.51, 229.3 etc. will require a reduction in oil change interval (drain interval approx half that of 229.5). Why would you want to use a product primarily designed for diesel engines in a gasoline engine with an ash level clamped at <0.8%. In reality it has half the additive treat of the average 229.5 product & will not look after the highly loaded cam & tappet area anywhere near as well even at reduced drain. My recommendation is to ONLY use 229.5 at recommended drain on the Assyst. If you enter the lower quality products in the system they will work but are not ideal & the Assyst will automatically call you in for an early oil change. You won't find any sensible dealer using anything other than 229.5.
BTW ~ In SA ~ considered a torrid zone by Benz. 229.51 is not listed for the M274.
The Shell break-in oil used in Bremen, Sindelfingen, East London & every Benz plant I've been in is a 5W-30 synthetic. It has zero moly in it (high temperature anti oxidant) which you will find in Mobil 1 0W-40 Euro Formulation 229.5. Our additive company sells the additive system to Exxon Mobil. (oil sample analysis will show the differences immediately)
I am playing the Benz line that I wholeheartedly endorse. I've worked with them on the Service Products approvals program over many, many years. Benz owners are very lucky that Benz undertakes all the expensive testing & approvals process for them. Makes product selection dead simple globally.
We try to offer the best possible advice on this forum. If you choose to ignore it so be it.

The fact that Mobile 1 is recommended for the 274 engine, and is openly listed for AMG engines, is a strong indicatiopn of what oil the Factory fill is.
Obviously Oil companies want to associate their product to high end products, so they strike a deal with high end car makers, as seen at the mobil site, where Mobil 1 is openly linked to AMG and other high end car models. Probably AMG gets free oil, or Mercedes negotiated a better rate in general. It's a give and take kind of a deal.
Car makers sell engine oil at a premium under their original brand. They will not openly disclose which oil is put in the normal bread-and-butter models. The authorized service points would go Ape!

Mobil 1 is not the factory fill in most plants. It was listed as the primary recommendation at service centres & under the hood due to the Mercedes McLaren racing sponsorship. McLaren Honda is moving to Shell for 2015 & Mercedes GP is sponsored by Petronas. The Mobil tie is a hang back to the past.

Well it is nice to hear an oil man admit that oil recommendations put forward by the car makers, is purely based on the flavor of the month.
And here we were talking about how important oil spec is. Five minutes ago, your car would virtually break down if you put in spec 229.51 as opposed to 229.5
Engine oil is to men, what the latest cosmetic or cleaning product is to women. Once you start to use the new product, you are no longer able to compare what the result would have been, had you just stuck with the old product.

I'm not wasting any more time with you. You don't understand. We are not talking oil Brands here. We are talking oil specifications. 229.3 is an ancient spec that preceded 229.5. 229.51 is primarily a diesel spec & has been recently superceded. They can be used at approx 5000 mile drain intervals in some markets on the M274 but are far from ideal. The 229.5 can be used for 10,000 miles or more which will be the specified service interval for the car for that market. I have given you Benz long list of 229.5 approved products all of which are equal in the eyes of Benz or they would have failed the testing regime.
Enough!
I strongly stick to my recommendation to Stan and will discuss via PM with him.

I understand that in the manual, Mercedes recommends and approved a type of oil which you "Strongly" warns against.
I also understand that when confronted with this, it made you very upset, and prompted one personal attack after the other.

It is allowed in the manual for short drain intervals for 274 only. This might occur in some third world countries although I know of none that actually do it. It is certainly not allowed for NA service intervals. Anybody with half a brain is going to use the premium 229.5 product.

My comments to Stan remain.
Then perhaps you should contact your close friends at mercedes who wrote the manual, and stop shooting at the messenger.
I have to say that reading your many many many posts in this subforum, I find your life fascinating. As a retired person you certainly break the mold. You are clearly an expert out in all things. Having the very latest and definite (not even publicized info) as to what Mercedes use for factory fill, to managing the Mercedes F1 team, driving McLaren cars for free at will, participating in many many many track events. The list goes on. Fascinating stuff. I deeply apologize if i have the audacity to doubt what people state as facts. I am afraid that you will have to live with that, less of course your growing displeasure with my presence, will prompt you to try provoke me and then Ban me when i reply in kind. It's not like that would be a first for you.
