Thinking about getting a vac system and changing my own oil from top.

What oil is everyone using now for diesels?
Mine is a 2009 E-320 Bluetec with 41k

I see a Mobil 1 5w-40 but for diesel trucks?
The ESP I think is 5w-30?

Thx!

It depends on the climate where you're at, and the mileage on the engine. Here in SoCal, I use the Mobil Synthetic 0w-40

IN NC Mountains with 4 seasons - nothing too harsh at all. Garaged all the time (heated) - and have 41k on it now.

Here's a thread I found for you: https://mbworld.org/forums/e-class-w...il-change.html

It has to be 229.52 certified

I'd recommend Mobil1 5W-40 or 0W-40, European Car Formula. Dealers, from what I understand, basically use both, or - rather - switched from using 0W-40 to 5W-40 due to some bleed down issues in their AMG engines. You can't really go wrong with either, but as a previous poster said, it's best to tailor it to climate.

Mobil1 European is not 229.52 certified. The European oil is good for vehicles without the DSP (?) system. I believe that the European oil is rated 229.51. This is what I use in my 2006 cdi.

Didn't read OPs post and subsequent replies carefully enough, I meant for gasoline engines, my apologies. You're right that is not DPF safe.

M1 5W/40 used the year around. But here in Cincinnati, our winters only have a few below freezing days and our beloved E350 4Matic is always garaged over night.

Here's the list of approved oils:

Both 5W30 and 0W30 are fine for your climate.
