Engine oil

[saff]

Hi,

I recently changed the engine oil on my 2006 S211 E220 Cdi and used Mercedes own brand 229.51 oil.

I have just found in my garage an almost full 5L can of Mobil1 Turbodiesel 0-40. This is about 1 year old. It says MB 229.5 so is compatible.

Would it be safe, would you say to use this and the remainder of the MB oil together for the next oil change? I guess this would be around 6 months from now.

Any thoughts?

Cheers Steve

Without a doubt safe if both within spec although the mix will default towards the lower spec.

Good example is people topping up synthetic with mineral. you lose a % of the synthetic benefits

Cheers Ditch.

I suspected as much but its good to get a sanity check sometimes.

You can see the specs here:

Mercedes-Benz Specifications for Operating Fluids: Engine Oil, Gear Oil, ATF, Coolant, Brakefluid

229.51 is better as it is lower ash.

223.2 shows you what can be used where

Does the car have a DPF ? If not then the 229.5 will be fine. That the oil is 1 year old is absolutely not a concern.

 

[tonysmb]

DPF is the critical point.

If your car has a dpf, then the oil will need to be 229.51 or possibly 229.31 spec, and maybe some older specs, but the main point is that the number ends with the '1'.

DPF or I think they are called (Dencitey particle filter)
Are a right pain, had a golf TDI that had one and it was for ever getting clogged.
Would have to stay in 3rd at 4tho Rev's and drive for about 3 mile like this just to clear the dam thing

DPF is actually Diesel Particulate Filter, I think. I've never had a diesel, and DPFs are one of the things that would put me off buying one.

Hi guys and thanks for all the replies.

This is the first chance I've had to log in for a few days.

I'm not sure if my car has a DPF or not, I wouldn't know how to tell.

Its a 2006 S211 E220 CDi pre-facelift if that helps?

regards Steve

Can you get it up on ramps? The DPF is a big chuffin box at the front of the exhaust, on my C220 it was pretty obvious when I saw it.

Alternatively does it say on the list, if you ask someone on here to run your VIN against one of the decoder sites.

Hi again,

I looked on a Russian (I think) site and my vin brought up "926 EXHAUST GAS CLEANING WITH EURO 4 TECHNOLOGY"

Does anyone know if thats a DPF?

It would be difficult to get the car up on ramps to check underneath as its so close to the ground.

My car W203 had the same EXHAUST GAS CLEANING WITH EURO 4 TECHNOLOGY" on that Russian list and I think that is the Dpf, but dont have it when we check and this means catalytic converter

Great 5 year old thread revival . So is it a cat or a Dpf ?.....Anyone ?

If it has DPF, it will have this on the Datacard:

474 DIESEL PARTICULATE FILTER

if you have on the back of your air filter box, some connector than you have the Dpf. If you dont have any electrical connector there, than you dont have it.

 

[Petrol Pete]

...Or someone removed the electrical connector and coded it out so you still technically have it.

What was the question again ..?

Like i said i changed the engine oil from 5w-30 genuine MB 229.51 to 5w-40 Mobil3000 this time and what did i notice? Higher consumption by almost 1 liter, lower engine power as the same power develops about 700 rpm later, and much higher engine noise. So as soon as possible I will go back to the original MB 229.51 oil as I had before, only this time I would like to try 229.52 MB oil. What do you say? (my engine 220 cdi, 110kw, 2006, without the dpf)

Choose the Daddy of all manufacturer specs.

What is the graph of the MB 229.52 specs. ? where can I found it ? 229.52 have a higher TBN.

Generally speaking, the higher an oil’s total base number (TBN), the better its ability to neutralize contaminants such as combustion byproducts and acidic materials. TBN is a measure of alkaline additives in the oil. Higher TBN oils neutralize a greater amount of acidic materials, which results in improved protection against corrosive reactions and longer oil life.

TBN levels are targeted for the intended application. For example, gasoline motor oils typically display lower TBN numbers, while diesel oils must manage the high contaminant-loading from soot and sulfur and typically have a higher TBN.

Can we say the MB 229.52 is better than 229.51 ?
