I have just purchased a MB with a 3 liter diesel and the manual says to use a 229.51 spec oil. I goes on to say that the only approved oils are:
Mobil 1 ESP Formula M 5W-40
Valvoline SynPower MST 5W-30
ELF Solaris LSX 5W-30
What oil would you use?
Dieselfan

I'm not sure how up to date this is:

Scroll to the bottom.

What year is your MB?

All the oils listed in this site link are exactly what is in the manual for our vehicle. It is a 2008.
Which of these oils would you use and why?
Mobil 1 is the factory fill or at least there is a sticker on the radiator supt that is from Mobil 1

I would use what is available locally at a reasonable price. This usually isn't the case with certain OE spec'd oils.

As long as the oil change interval is reasonable, any should perform perfectly. I would lean toward the thicker 40wts for southerners, and 30wts for northerners.

The MB 229.51 spec is for a long-life, low-SAPS oil with high-temperature shear resistance.

I haven't been down to the local NAPA to see if in fact they have the 229.51 Synpower MST, but I have a case (12L) of Mobil 1 ESP 5W-30 from AV Lubricants and a case (12 qts) of Amsoil AFL 5W-40. The Elf Solaris LSX is available from the Performance Oil Store in 5L jugs.

I just ordered a case of ten oil filters from Germanfilters.com, as well as an extra fuel filter. The stealership sells the oil filter, if they even have them, for 2.5x as much. Who knows what they'd charge for the fuel filter?

Peruse this thread on Mobil 1 ESP 5W-30. Also, this thread with analysis results of Mobil 1 5W-30 ESP at 4000 miles. I sent in a 5K sample and should have the results back early next week.

Mobil has both a 5W-30 and a 5W-40 version of 229.51-approved Mobil 1 ESP - depending on what you want. AVlube.com is the only place I've seen either oil as well.

Can't you use CI-4+ rated oils in North America?

Personally I would just use 15W-40 Delo 400. These Group II HDEO's rival the performance of synthetics.

No, that's why MB requires 229.51 for this application.

Sure, CI-4+ oils can be used in north America, just not in the MB OM642 turbodiesel.

There are NO dino oils, and few synthetics (at least in north America) that meet the MB 229.51 spec.

I'd also add that Maxlife Synthetic meets the 229.51 spec. Great oil.
