Review of (an idiots guide to) puma engine oil

Simply Mick, just run HPR5 and you’ll be fine...

And save a bit over the Enviro stuff!

True, except I already have the Penrite Enviro low SAPs bottle in the shed.

Mick, as Mike said it depends on the engine manufacturers oil spec.

There are roughly three levels of mid/low SAPS oils, it seems like everyone has their own particular specification, e.g. Renault is different to Ford/PSA which is different to GM Opel which is similar to BMW but different to VW and Porsche is different again....or something like that.

Which oil is it and to go in which engine Mick?

If we are to look at the published specs in the service manual alone:

2.2 Tdci DPF Fitted?	Published Oil Spec	Notes
DPF Fitted	WSS-M2C913-C	NO Aus delivered Pumas were fitted with DPF
DPF NOT fitted	WSS-M2C934-B
DPF NOT fitted	WSS-M2C934-C	'C' spec is backwards compatible with the B spec

.

EXcept that it's the other way around: no DPF = 913C | DPF = 934B/C

So is 934C ok for Defender 2.2 no DPF?

The workshop manual specifies the oil spec:

But the word on the forums is that it appears that dealers may use other oils (which I trust meets the ford spec), but not the oil brand as per the owners manual.

This more likely ties into the wheeling and dealing between LR and Castrol when it comes to supply agreements for supply of oil to the engine manufacturing plant and scratching their back as far as trying to secure long term oil sales for the vehicle.

When I started this thread many moos ago, I went balls-deep in the tech info, the the extent that I confused myself to no end. I called the Castrol tech line to discuss, spoke with people in the know like Rick (who is a great bloke to-boot!) and eventually came to the realisation that if the oil weight is right, if the specification it meets is correct, then I'm 95% set. The remaining 5% would be taken up by more frequent oil drain intervals, which I'm due for approx 10K Km changes. The modern oils are designed for extended drain intervals.
So in my logic:
1) Any oil is better than no oil (or old oil!)
2) The correct weight oil should be used
3) The spec should be met- ideally WSS-M2C934-B or C spec which is a Ford spec oil.
4) You could throw extra money about on a low SAPS DPF suited oil, but realistically, not required, as adequate protection is inherent in the specification and regular drain intervals.

By jove, I think you're right.
I DID say I confused myself with all this, right?!
I'm also going to plead the 5th with the facts due to the forum table layout- a real PITA to use...

RBP'd the offending table... hopefully someone can set the record straight for future knowledge.

Cool, so can we now assume that as Australian Defenders don't have DPF we can use either of those Castrol 5w30 spec oils because neither is going to clog our DPF?

...and that both are going to be equally good in terms of protecting our engines?

I'd be confident doing so, as long as the oil change intervals are maintained.
Warranty wise, I don't think there would be a concern if it meets the published 'ford spec' and the correct weight.
As for clogging the DPF, you cannot clog what isn't there!
