Mine does not have a DPF.
So can a DPF mask an oil consumption issue? I suppose the only way we will ever know is if a DPF equipped D4 gets its oil tested at the end of the service life of the oil...

Just playing devils advocate.
You've gone 12 months?
And it reads as per your pic?
Because its between min and max I would suggest that reports as "no issue".
There's nothing wrong with an engine using a little oil. As long as its not excessive.
You tow heavy, perhaps it's burnt a little more depending on where you went (loaded harder etc)?
Just putting it out there!
It hasn't been 12 months the oil was topped up at recent service less than 6 months ago. It has only done 6624klm since that top up.Quote:

That's now my concern, thus the questions or statements about other brands having a built in ability to monitor dilution,,,,Quote:

Diesels just use a bit of oil, that's all. Turbos leak, turbos burn oil, it's not really a big deal, and I'd say 99% of 3l's don't have DPF's, I'd get worried if you are losing over half a litre every six months with normal driving, you probably do use a bit more when towing, so just top it up. You guys seem to have gone in to way too much detail about this.
Also as far as I'm aware, one notch is 100ml
It is getting confusing now. Some say 300 per notch my dealer says 250 and here we have a guy who works on the saying it's 100.
The other issue here is actually getting oil for these when traveling you can't buy the oil anywhere...
The manual says the car will tell you how much to put in if it needs it. Have a look at page 206/207.

"If the oil level is below the required operating range, a message advising you how much oil to add will be displayed, e.g. Add 0.5L. Add the recommended quantity of oil then recheck the level."
If the above message is a reasonable example of what you would get when the level drops too low, then it would seem LRTech23's amount would seem on the money.
My level is sitting at the same as Mowogs after ~9000km since oil change.
The oil is very difficult to find, the oil we use is Castrol C1 Powerflow 5w/30. Clearly we get it directly from castrol and it is my understanding that t may only be available in 20 and 205l drums.Quote:

But I suggest using 100ml per notch as a general rule. Always recheck after you have topped it up as well.
I think my full level may actually be below the sensor full level. I think it may have been burning oil till now.
So working on these cars everyday, you'd know if LR have compensated for the vehicles that have DPFs or not. Do LR conduct viscosity tests on the oil or does the system compensate when measuring, like other brands do?Quote:

Two cars come into the workshop, one has a DPF the other doesn't, one is showing no oil usage (DPF), the other is.......wouldn't that trigger a question?
I'm scratching my head....if D4s that are running 'neat' oil are burning engine oil, what are DPF fitted vehicles really doing...and what is this loss of viscosity doing in terms of wear to the engine?
