Indy shop used Liqui Moly 0W40 synthetic for Service A, is this oil ok?
Hey guys,
Can someone who knows more about motor oils tell me if this is ok?
They used Liqui Moly instead of Mobil 1.
Question 2: Can I top up the Liqui Moly 0W40 with Mobil 1 0W40 in case the level goes down? or is it bad to mix oils?
Thanks!

Yes you can mix oils, however I would complain about the oil used.
http://bevo.mercedes-benz.com/bevolisten/229.5_en.html
http://bevo.mercedes-benz.com/bevolisten/229.51_en.html
These are the approved oils for our engines (.5 for the earlier engines, .51 for later modules, I am not sure of when the switch occurred)
While Liqui Moly is listed, the 5W40 and 0W40 are not on the approved used list.

Is this really an issue? What if I change the oil to Mobil 1 0W40 in 5,000km from now. Is there any risk to my car with running with this oil or any side effects?
I'm not sure if the indy shop will be willing to waste all this oil, but if this is really an issue I will change it even if I have to pay it again.

It's not a major issue. The old listed on bevo were just certified by mb, there are plenty of other good quality oils that will work perfectly. You can probably wait till your next change. The problems come if you need warranty work and mb figures out you used some other oil, they will potentially deny the claim.
Again, you should be fine, but you should let the shop know that the oil is not on the list. Outside of the warranty if yours is expired like mine is, it's a non issue

The Liqui Moly 5W40 is a 229.5 approved oil. The 0W40 is 229.3, which is a depreciated spec and not approved for the C63. While it likely won't do any harm, I would change it sooner rather than later.
You won't harm anything by topping up with a different brand, but again, it should only be a stop-gap measure (i.e. you're on a road trip and your "check oil level" warning comes on) until you can drain it and replace it with a 229.5 approved oil. I certainly wouldn't push the car either with an unapproved oil and/or a mix of two different oils.
If they can't even bother to put the right oil in the car, IMHO you need to find a better shop.

The 229.5 and 229.51 are what is important. Wasn't it mentioned in a thread last fall/winter that MB no longer recommends Mobil1, but Fuchs (sp?) now? Something about racing sponsorship changing.

Everyone freaks the eff out over oil. 229.5 and 229.51 simply mean the oil manufacturer paid to have their oil tested and certified for use in an MB engine. Some companies don't want to pay and make perfectly good oils. Some only pay to have a certain viscosity tested. Either way, using a good full synthetic of the proper weight is what's important. And Mobile 1 is not good enough IMHO. As stated above, unless you have a serious failure and MB decides to send your oil in for analysis and you need warranty work, you should be fine. And even if they send the oil for analysis, what's going to happen when they test it? It probably meets the specs for 229.5/51 anyway. Run the oil you have in there and don't sweat it.

Thats pretty much what I said.. but I was typing from my phone so I kept it short.
However, Diabolis noted, if the shop you go to does not at least take the time to go through the list, even if they do use another oil (they should at least call the customer and note that the oil they are using is just as good, just not certified), it might be time to find a different shop.

Your dealer is correct and last I looked the 229.5 was the only oil approved for our cars ( except in Western Europe).
See here for specs per engine type : http://bevo.mercedes-benz.com/d/d/en/Spec_223_2.pdf

His dealer is wrong... by your own post and the spec sheet. 228.51 is for Diesel. 229.51 is just the next generation specification for engine oils for newer engines, the m159 for example, which of course is very similar to the m156.

And I looked up the oil recommended for a 2014 C class and it's still 229.5. Went one step further and looked up a 2014 diesel powered car and the manual calls out to use 229.51 for diesel engines. (go to the above website and look at the 2014 E sedan/wagon manual, page 422)
I think maybe the dealer was correct. But in reality, I'm guessing that you can use any of the oils from the 229.51 and be fine.

The 229.5 spec has specifically been designed for high-performance gasoline engines, while the 229.51 spec is indeed the low-ash diesel spec for the bluetec engines that have the fine particulate filters. The difference between the two is the additive package. In Western Europe where they have had much cleaner gas for a long time (and thus less garbage and acid to neutralize in the crank case), the 229.51 oil is also approved for the M156 engine. Now that North American gas is finally catching up, MB is starting to use the 229.51 spec oil here as well.
In general, the 229.5 oils have better anti-wear additive packages but are not as environmentally friendly as the 229.51 spec.
Given a choice between the two, for the C63 I would take a 229.5 over a 229.51 spec oil any day. They produce higher emissions from the tailpipe, but offer better protection for the engine.

Well... just to add to the confusion, his dealer is not really wrong - it's the OTHER dealers that are technically wrong. BEVO still lists 229.5 as the only approved oil spec for the M156 motor in North America.

EXCELLENT information, thank you very much.

Can someone explain to me then why on the 229.5 (or 229.51) spec sheets there are 0W-30, 0W-40, 5W-30 and 5W-40 oils listed? I remember reading elsewhere that we should use either 0W40 or 5W40, and then I recall that being limited really to 5W40. Since I'm new to this type of stuff, what am I conceptually not getting about multiple weight oils being listed on the appropriate spec sheet? And yes, I know I'm going full-on OCD about this...
thanks

thanksit lists all approved oils (and weights) of the 229.5 spec
certain engines require certain weights (M156 is 0-40 or 5-40)
it's strange
US and RoW 229.5 only
Western Europe 229.5, 51 or 52
???

Hadn't thought of that
May have been certified with a fixed list oils and it's a hassle to add them?
Euro standards are more stringent
Maybe they mandate the newer stuff
But MB prefers the older spec so they use it where they are not required to use the newer
But it's western europe only

Well, thanks. After searching the 1206 brands/weights of oil available at autozone and pep boys here in NJ, I could only find Mobil 1 ESP Formula M 5W-40 that complies with the 229.51 spec only. Although I guess my '14 C63 M156 probably requires 229.5 spec (and of course the ESP isn't on there) I read that the US M156 units will probably move to 229.51 in the future anyway. So that will have to do the trick. They couldn't have made this more complex, however... And if anyone tells me I made a poor choice I will drink the 6 quarts I purchased and put an end to this OCD shopping debate!
