For the oil experts -

The manual says use WSS-M2C934-B SAE 5W-30 - is that the same as C1 ?

Ive got some C3 oil could I use that ? (long life fully synthetic for BMW 330D)

The blurb for C1 and C3 says "for high performance petrol/diesel engines with dpf" . is their really much difference ??

I wonder if the C1, C2 C3 stratification is akin to the drug companies pushing different versions of the same cough remedies for different types of cough - all marketing hype as its fundamentally all the same and makes no difference. Jules

Here's what the specifications mean:

ACEA C1 oil is suitable for diesel engines fitted with diesel particulate filters (DPFs).

ACEA C2 engine oil is suitable for diesel engines fitted with diesel particulate filters (DPFs), this specification is very similar to ACEA C1 but with a marginally higher SAPS limit.

ACEA C3 engine oils are suitable for diesel engines fitted with diesel particulate filters (DPFs). Very similar to C2 but without fuel-economy requirements.

ACEA C4 spec oil is a top tier diesel engine oil specification for vehicles with diesel particulate filters (DPFs) and Three Way Catalysts (TWC). Oils that meet this specification offer increased life for DPF’s.


What is SAPS?

SAPS stands for sulfated ash, phosphorus and sulfur. They comprise a significant portion of a motor oil’s additive content. Sulfated ash is not added to oil; it is the result of additives in the oil burning and creating ash. The additives that can produce ash are most commonly used for total base number (TBN), but also help in other areas, like antioxidancy, anti-wear, cleanliness and soot handling. Phosphorus provides anti-wear properties and further antioxidancy, while sulfur contributes antioxidancy, anti-wear properties and engine cleanliness.


SAPS Levels

Given the beneficial properties these additives impart, it’s easy to assume a higher concentration equals a better oil. But higher SAPS levels can be a detriment to expensive exhaust devices, such as diesel particulate filters (DPFs) and catalysts. The European Automobile Manufacturers’ Association (ACEA) and original equipment manufacturers (OEMs) realized the importance of using motor oil formulated with precise SAPS levels, and lower limits were established in 2010.

The three different SAPS levels of European motor oils can be confusing, especially when considering the same viscosity motor oil (5W 30) is available in mid- and full-SAPS European Car Formula options.

not worth putting a lower grade oil in,it will not be covered under warranty if an engine fault occurs as it would be checked before any warranty work was undertaken!

i always use

Motul 8100 X-CLEAN+ 5W30 this is very good and not expensive

or

Motul 8100 ECO-CLEAN 5W30

if you want typical oil

Motul SPECIFIC 913 C 5W30 to Ford Jaguar Land Rover #bvrgarage

I suppose if a big claim was pending sending off a sample of oil is a small cost if it means the customer foots the bill in the end.

But I just find it hard to believe that there really is need to use all these different oils - modern common rail diesel engines (with last 5 years) are all basically the same (the older VAG PD engines being an exception - the injectors requiring a bespoke oil).

Why does my 2015 SD4 need a different & more expensive oil than the previous TD4 - very similar engines, both have Cats and DPF. Jules

As far as I know all landrover engines fitted with a dpf need the higher spec oil to protect it,not just the 2015my.
