dpf and engine oil

[Golfatha]

Hi new member here car is a 2011 ml350 grand edition in silver,my first mercedes and I absolutely love it.
I have a question that hopefully someone on here can answer for me as the info I got from my local mb dealer was sketchy so here goes my engine number starts 642 and I’m wondering if this model has a dpf and also which oil I use in this engine I.e 229.51 etc and what grade I.e 5w 40 many thanks in advance.
P.s love reading this forum

Yes you have a DPF, and probably 5W/40 is the oil - or 5W/30. I'm using the latter but starting to favour the former.

Welcome to the Forum BTW!

With a DPF you need to use 229.51 which is a low SAPs oil.

The problem with dealers in general is that you don't get to speak to a technical person.

The Service Advisor's training teaches him or her how to price-up a service, not how engines work or what the oil does.

If the car is booked with an official MB dealer or with an established MB specialist, then you need not worry at all as they will use the correct oil for your car.

If you are supplying your own oil to the garage, or having the service carried-out by a garage who do not specialise in MB, or just going the DIY route, then you need to make sure that the oil container's label specifies that it 'Meets..' or 'Approved by..' MB Spec Sheet 229.51.

only said use 0w-30

You can use any that the 229.51 spec covers which is 0W30, 5W30, 0W40 and 5W40. There are lots of approved oils to chose from in the link below but the cheapest is MB's own oil bought from Mercedes Newcastle on ebay.

MB 229.51 - Low SPAsh multigrade service engine oils (Specification 229.51) - Mercedes-Benz Specifications for Operating Fluids

Great thanks a lot for that info 190 that is where I was at today with my car as it had a bit of a lunge while changing down gears when cold and I asked about oil when I was there. Is the 229.51 fully synthetic oil cheers

Just let them get on with it then.... they'll use the correct 229.51 oil.

(BTW all MB oils are classified as 'full synthetic' BUT this classification is in fact very broad e.g. it allows some non-synthetic oil to be mixed into the formula etc)

Yes all 229.51 oils will be marketed as fully synthetic. In the strictest sense almost none of them will be but it's not something to worry about and to explain why they are not 100% synthetic is too involved for this forum without boring everyone to tears. MB's spec 229.51 focuses on how the oil performs in a number of specific tests and that's what we should all be concerned about rather than the "full synthetic" label. Basically by defining their own quality spec MB have saved us the worry of which oil to use.

If you want to know what MB's specs mean in detail it's all here:

I get the oil for my c220 from mb Newcastle eBay shop. Genuine mb oil is cheap these days.

Yes, there's "synthetic" and then there's synthetic. - Technically the phrase "fully synthetic" is a marketing term, so something like an esther base stock is quite different from one blended with mineral oil.

I imagine that will be good oil as Motul is one of the few manufacturers still making real synthetic oil based on Group 5 Esters rather than group 3 mineral oils.

To clue to real synthetics is in the price and I expect that this Motul oil is double the price of the genuine MB oil from Mercedes Newcastle. There will be nothing wrong with genuine MB oil but I smile when people think they are getting the very best oil when it's simple impossible at the price for it to be a true synthetic.
