2012 Range Rover L322 4.4 TDV8, 25859km UOA, LiquiMoly C1 oil.

[SpitfireS]

Hello All,

Below is my first UOA from my 2012 Range Rover L322 4.4TDV8, OCI 25859km.
To be honest I don't know what oil went in, it was Liqui Moly C1, is what I was told.
There are some red warnings, maybe all based on the fuel (Kraftstoff) content being 7,2%
This is quite high, I guess it has to do with me taking the sample 2-3 days after some forced DPF regeneration.
I though the fuel would evaporate quicker.
Wear metals look good.
The oil did shear down to a 20 weight, the fuel did not help there, no doubt.
TBN was low but not zero.
The soot (Ruß) was also low, for a diesel that's good I guess.
And no other contamination.

Now I'm using Shell Helix Ultra ECT 0W-30 C2/C3
Landrover does spec a C1 oil for this car, because of the DPF.
But I could not find any C1 in 0W-30.
Besides, Shell claims this oil is "the most advanced emissions-compatible technology to keep DPF's clean"
Time will tell how my DPF is going to perform with this oil.

First positive thing is that my fuel consumption, during a recent 900km trip, dropped compared to what it did before under very similar circumstances.
It went from 1:10,5 to 1:11,3.

Any comments are appreciated.

Unless your engine is consuming oil then you're unlikely to have any issues with ash blocking the DPF. If you are having issues that you need to force regeneration then it would be wise to diagnose and repair. A lot of people get a blocked DPF, replace the DPF but never fix the underlying issue causing the blocked DPF in the first place.

Also worth noting that you oil probably didn't shear, the viscosity loss will be due to the fuel content in the oil.

Shell Helix Ultra ECT C2/C3 is a great oil! Just very expensive over here in the UK.

ACEA C1 has been withdrawn.
All ACEA Cx oils are DPF,OPF friendly. However, C1 had a really low maximum ash at .5%. Currently C4 has the same maximum ash but it will have a higher hths (same as C3).

If you are following your RR owner's manual. that's outdated. Your vehicle is 12 years old and a lot of changes have followed since including the oil. Get the current oil available, there a lor of improvements to it than your owner's manual required. Ravenol, Fuchs, Castrol-BP, Liqui Moly are all good brands

Thanks for all the comments.

What I would like to add is that I changed oil when the car 'told' me to.
Maybe that was a bit too long?

The forced regeneration was done mainly because I just bought an OBDII reader that allows the function.
I wanted to see how low the measured pressure differential over the DPF would get after a complete regeneration.
As far as I know I don't have any DPF issues, I've had it properly cleaned twice now, as as sort of routine maintenance.
On Range Rover forums it's not uncommon for people posting warning messages about the DPF.
Driving habits and short drives increase the soot/ash build up, so even when nothing is wrong one can still end up with a blocked DPF.
One could say, the thing that's wrong is using a 4.4 diesel for short drives.

As far as I found the Shell Helix Ultra ECT C2/3 was introduced before ACEA dropped the C1.
Shell probably never formulated it to be C1, the ACEA dropped it for a reason I assume.

The 2012 owners manual spec's 5W-30 C1, or better said Ford WSS–M2C934B.
I have no doubt the ECT will do well and will not load up the DPF.
Time will tell.

What I was pleased to see was that the oil had low soot levels.
Apart from the high fuel content - what I think was caused by the regeneration before - the OCI wasn't way way way to long, as many say the OEM OCI is.
