Here is my result with mobile1 0w-40, sample is about 1yr/12k miles old..
I was a bit worried about going over 10k miles between oil changes..
However, test result looks good and blackstone said the sample could last 15k miles..

glyn, i here u . just wish we had some hard data, like an oil analysis of Royal Purple after 10-13k miles . maybe ill spring for it, how much and where , how to send for analysis. ill google and try to find an oil analysis for u to see and explain, thanx, mike

One oil sample tells you nothing really (just things were OK or not for that period) - You need to plot a trend & evaluate & rate engine parts when the lubricant is stressed.
The only hard data would be getting through the Benz stringent test regime.

Glyn,
First thanks for the info you've supplied the forum with.
My question is what your opinion on Liqui-Moly's MOS2 oil. I normally use the Liqui Moly version recommended for my m111k engine and it's got relatively few miles on it (about 60k miles). Is there any advantage to running 1 Liter or more of the MOS2 in there?
I'm not using Fleece, but the normal benz filter. I have the old style change indicator, which goes from RPM and other factors, not the optical type (my assumption). I have not explored going 229.5 compliant yet, but will consider if the fleece filter slightly extends the 229.3/31 oil I'm using enough to offset the price. 229.5 oil is significantly more expensive here.

To my knowledge a Mann + Hummel fleece filter is not available for the M111. They did the development with M+H after the M111. You should run 229.5 oils in your engine for best wear performance. Forget about MOS2 additives. They do not work well in engine oils & do not remain well dispersed.

Just so you know, that oil was not Mobil 1 0w40. Looks to be the Mobil 1 Formula M EURO 5w40, which is fine, just a bit less calcium, moly, etc.

Great result!
sknight - Don't get the moly we talk about in these samples confused with MOS2 additives we were talking about.
The Moly in the Mobil, Texaco, Caltex etc formulations is a high temperature antioxidant.

Fill in your profile properly. This is not an appropriate thread for your question. If your car is a W204 the AMG lights will fit

20 000KM Intervals
Glyn,
W204 C350 50 000Km:
My car is now receiving oil changes at 20000Km intervals.From what I can make out the dealer is using Mobil 1 SHC 5W/30W .Engine/Mobil says it can only be 5W/30W for Mobil 1 SHC.Could not get the exact type out of the dealer.
How good is this oil for W204 C350 2008 ?

This is a wonderful thread conducted by real engineers.
It confirms my seat of the pants experience with M1 0-40 and the recommendations of my tech, namely, that is a superior product for engines that can and should use it.

My preference is for M1 0W-40 Euro formulation at 15,000Km drain. It is available from Engen SA.

Amsoil fill
Glyn, I'm testing out Amsoil this fill, and it's MB Spec 229.51. I saw these tests that all showed Amsoil outperforming Mobil1 and just wanted to get your opinions on this. Here's how my engine wear has been trending using Mobil1 fills.

@Glyn M Ruck: In Mexico the oil service interval is 25,000 KM (15,625 miles). It is surprising to see most 229.5 oils start at 0W or 5W. One would think that for warmer climates where the temperature averages 30° C and is never below 23° C, 10W-40 would be more appropriate.
Others in threads in warm climates (Austin Tx) complain about crankshaft noise upon startup supposedly due to lack of oil in the bearings, according to their MB dealer.
What is the best weight recommendation for 229.5 approved oils in warm climates? Consider that most can drive at 220+ KPH speeds regularly.

Regarding 229.51 oils. Your results will be interesting but while this form of go-no-go testing is useful for determining service intervals & potential trouble, it cannot replace the long term endurance testing done under 229.5 qualification by Benz. Ash limit stipulations by Benz for 229.51 formulations effectively limit the additive treat of a 229.51 oil vs. a 229.5 treat product which will always have a higher treat. Yes some additives are ash free but this does not change this conclusion. Aside from cam & tappet wear, Cat protection et al the two major differences between a diesel & gasoline formulation regard combating engine sludge. Diesel formulations are designed to combat high temperature sludge while gasoline formulations combat low temperature sludge. Sludge adheres to engine components & does not show itself in standard insolubles & spectrographic analysis because it does not drain in suspension with the sample.
The AMSOIL comparison is comparing apples with pears as regards Benz. All Mobil 1's are not equal as I discuss in the Definitive. Let them do a comparison with Mobil 1 0W-40 Euro formulation. It uses a totally different base oil.

Causes of startup noise in Benz engines (apart from at oil drain)
- Bearing noise (mainly small end) clearance - requires repair
- Piston slap due to ultra short skirt pistons - fine if slight and stops at operating temperature. Benz metallugy maintains fairly consistent piston to bore clearance with temperature change unlike engines with iron blocks or liners.
- Timing chain slap prior to oil pressure reaching max. - Hydraulic tensioners require repair.
- Camshaft adjuster rattle - require deburring or replacement.
Don't allow dealers to BS.
In torrid zones like SA & Mexico. Even with fleece filters drain should be 15,000 Km. This is what I recommend.
MBSA settled on this years ago even when they are carrying the cost of the "free" maintenance plan as they do here.

@Glyn: thanks for the info and recommendations. The oil confusion situation exists because in the USA/Canada W204 manual MB purposely quashes the issue on a spec, leaving the customer at the mercy of the MB dealer to determine what an "approved engine oil" is. Basically causing any oil change outside the dealer to be an excuse to void the warranty.
Another page of the manual refers the owner to the mbusa.com website for clarification, however after extensive searching their Catch 22 always mentions just "approved engine oils" and "authorized Mercedes-Benz center". Yes, PROFIT with a smile. Hmmm... no smile, just a bill.
Other lubricants are clearly specified. Same in the Spain/Mexico/South America manual, no specific recommendations of either "approved engine oils" and NEVER a reference to 229.5... See the three graphics.

Bill. You are supposed to get a booklet like this with your car.

@glyn - Thanks, and no, one did not come with my 2010 W204. Not in English nor in Spanish.
If anyone has a PDF of such a parts and approved oils guide for the W204, many would appreciate the post.
