Mercedes E250 W212 Diesel- OM651
Need help with exact engine oil specifications for my car

My car is E250 CDI Facelift 2014
W212.003

My car’s service is due in which engine oil and filter will change. So, I wanna know exactly what specifications engine oil is recommended for my car. Like there’s so much confusion 228.51 or 229.31 or 229.51 or 229.52 and what’s the exact difference in all these engine oils. Can anyone tell me what engine oil will go with my car exactly with my VIN?
Thanks in advance!!

Look up your engine here: Mercedes-Benz Operating Fluids

Do you know your engine designation? You can find it using www.lastvin.com with your VIN.

Still my question is which one belongs to my car 228.51 or 229.31 or 229.51 or 229.52?
This mercedes fluid operating website is only useful if I know which engine oil out of these.

There is no confusion. They are all acceptable. So long as the oil meets any of the four specifications, you are good.

You dont have a DPF or you removed it? If not present use any of the four that you would like. Most here will say the .52 is the only way to go (I dont agree with that but thats there religion). If you have a DPF then you supposedly cant use the 229.31 according to MB.

OM651 2014 e250 if in US then it does have one unless it was tuned and removed. Not likely as you have to make your own downpipe to replace it which most people dont. If you look at the engine with cover removed on the passenger side there will be a big portion of the exhaust, think thats the dpf.

The requisite MB oil spec for your vehicle should be in your owners manual.

the table at that link, https://operatingfluids.mercedes-benz.com/sheet/223.2 says which oil spec for which engine. you have OM 651, so thats 229.51 or 229.52. your owners manual should state what oil grade for different ambient temperature ranges. 229.51 approved oils are here, https://operatingfluids.mercedes-benz.com/sheet/229.51, most are 5W30, and thats the recommended oil for almost all temperature ranges... I would not use a 0W oil unless you live above the arctic circle and its always well below 0C


(from the 2014 E sedan/wagon owners manual, page 423)

Temp is normal , coolant is old, easiest is drain refill , don’t use a “works in all car” stuff, my 13 is blue, xerox g48 I think. Foggy light not normal and will coat lens reducing output .look at gasket sealing in bulb or seem separation but I only have experience cleaning the insides - Denatured Alcohol, when light is removed. It will corrode the socket. A separation can be siliconed . A gasket can be replaced or moved in place.
Old coolant will allow corrosion. You don’t want that .

I think Zerex G48 is the correct coolant.
