Hi all,

I've looked into this quite a bit – checked a few forum threads, called some local Land Rover services (including the dealership), but I’m still not completely sure which engine oil spec is actually correct for the TDV8 without a DPF.

According to the Owner's Manual for my car, the recommended spec is WSS-M2C913-B, which nowadays has been replaced by 913-C/D.

Some local LR dealers, based on my VIN, said the correct spec for the EU market is WSS-M2C934-B (or its newer equivalents). My car is for the EU market, but definitely doesn’t have a DPF (I checked the exhaust system myself). The thing is – this spec (934-B) is meant for cars with DPF, and I'm not sure if the VIN even encodes DPF presence.

From what I’ve read and based on some research, using DPF-specific oil in a non-DPF engine isn’t ideal:

*WSS-M2C934-B oil has reduced high-temp wear protection, optimized for DPF protection – which may be insufficient for the TDV8 without a DPF.

Using a low-SAPS oil in a non-DPF engine can lead to inadequate lubrication, camshaft wear, or even turbo problems over time.*

To make things more confusing, I checked old service records and for the last few years the car has been running on Castrol Edge 5W30 C1, which is also aimed at DPF-equipped engines.

So… is there a clear and final answer on which oil spec is actually correct for a TDV8 without DPF?

Cheers,
Greg

5w30 A5 is correct for 2.7/3.6 without DPF

That’s what I thought as well — 5W-30 A5 meets M2C913-B/C/D, which should be fine for engines without DPF.
But it’s confusing that LR services say the official recommendation is WSS-M2C934-B (ACEA C).
Is it just a generic response based on VIN, or are they pushing what's in stock?

Cheers,
Greg
