^ Thanks for that - useful post
I checked my Service invoices last night - garage uses C1 (Hurray - my D4 has no DPF), checked my Top Up oil that I have been using for years - Castrol Magnatec 5W 30, but cant see C reference (Boo) - but only ever used in very small quantities (D3 / 4 never oil users) between changes so assume will be OK.
5W30 C1 on order as Top up oil
If your D4 hasn't DPF, you can use C2 oil!Discovery 5 tdv6 HSE Corris Gray Outback Engineering Limited Edition IID Pro MV License

C3 has the HTHS higher than C1 an C2, that means more viscous friction, not good for the rotating bearings issue.
Hello.
Are you sure ? My idea was the higher HTHS is a better protection ?! Nope ?
Thinking buy C4 oil for my D4 sdv6 with DPF.. Marco.

Having previously driven round for hours trying to find the right grade (as per handbook) have always just grabbed top ups from the stealer when I'm in there, however I've bought from three different dealers and been given three different grades of oil, all telling me it was the right one!
can someone do a sticky with links for the right bloody oils please.. I'm getting headaches just thinking about it.www.southeast4x4response.org.uk Responder of 9 years service SE140

Apologies if I haven't been paying enough attention
Is 5W/30 – WSS–M2C934–B also the correct spec. for the later EU6 (Adblue) SDV6 engines?2006 D3 HSE (Original & still the best)-GONE
2010 D4 HSE (A bit bling)-GONE
2014 D4 HSE (Almost too bling)-GONE
2015 D4 HSE (A heated what?)-GONE
2016 D4 Landmark (Written Off)-GONE
2016 D4 Landmark (Surely the last!) PD1881 rims-GONE

Ordered and being delivered tomorrow - all sorted, confusion over.
Manual does state WSS–M2C934–B (MY10, page 205) but doesn't define as C1 - so thanks again

Sorry don't understand why is this a problem ? You think its not good the rotating bearings issue ?
I just want to understand before buy a wrong oil spec..
As the LR spec is the "lower" we can do or not ? My idea is trying to found a better protection (if possible) for the engine...Marco.

because more viscous friction tends to drag (rotate) the bearings when the crankshaft rotates, especially with cold oil
Also the lion engine is an engine where the coupling dimensions are very small, this is another reason for use medium HTHS (Ferrari, AMG, JLR sports engines are running 0W/20 oils with HTHS 2,0)
Experiment show that wear problems appears when HTHS is less than 1,4, our oil is more than 2,9 (up to 3,5)Discovery 5 tdv6 HSE Corris Gray Outback Engineering Limited Edition IID Pro MV License
