Oil Specification

I'm about to do my first oil change since buying my CRD so I've been looking for a good value for money oil that meets MB 229.51.

This has got me thinking! There are a few different oils that meet 229.51 ranging wildly in price and even weight, for example Mobil 1 is available in 5w-30 and 5w-40 but both meet 229.51.
I'm curious to know what 229.51 actually specifies, is it just the low ash properties required for the DPF or does it specify properties required for properly lubricating, cooling, cleaning the engine?

If 229.51 is an ultimate, exhaustive specification for the oil then I'm tempted to use GM Dexos 2 which claims to meet this standard but is significantly cheaper. If its just an ash spec then I'm more inclined to shell out the big bucks for a premium brand.

Any feedback gratefully received!

i haven't seen the particulars of the specifications required to meet 229.51 and i could be wrong but i doubt MB would publish it. as far as i know the 229.51 is as you mentioned for low ash (Diesels with a DPF) and for the extended drainage interval. try searching the forum (particularly the DPF delete thread i believe) as there has been considerable discussion already regarding oil options both with the DPF and without. i personally use total quartz ineo mc3 as it's the cheapest i've found ($39.50CAN+tax) for 5 litres which is 3-4 dollars/litre cheaper than the cheapest 229.51 mobil 1 i could find (one dealership wanted $14/litre!). as with most things you'll get a variety of opinions on what oil is "best", but i use the least expensive oil thats meets the 229.51 spec and haven't had any problems after 3 - 20,000km oil changes.

As far as I know the UK version of the WK with the Mercedes diesel engine DOES NOT have a DPF.

229.51 oil is designed to specifically help the DPF.

I would look at the Mobil 1 0w40.

Hi again!

So after getting under the car I now know I do not have a DPF.

The recommendation for none DPF vehicles is a part synthetic, 10w-40. Has anyone used this or do you stick with the 0w-40 fully synthetic?
If I got the 10w-40 route I guess more frequent oil changes would be required.

Regards,

Jamie

Full synthetic is better, and Mobil 1 has never let me down. I used in my gassers and now in my oil-burners.
