The new/old engine in the latest Ranger,an updated Lion engine is specified at 15,00Km,a lot shorter intervals than LR's 26,000Km.Quote:

Most manufacturers are at around 15,000Km/12 months,which seems to be the industry standard.
26,000km! No wonder they blow up.Quote:

Is the long interval applicable even in arduous conditions (which some manufacturers, wisely, say includes both towing and peak hour conditions for a significant percentage of time in warm conditions etc)? Cheers
For the D2/3/4,ardious is half those distances and times.Quote:

Quite a few times i had the engine oil tested,and at 15,000Km,they generally said can be left if you want.I once left it until 20,000Km,as the test at 15,000 came back not bad,and they said it is OK,but a change is needed ASAP.
LR at the time were quoting 20,000Km intervals for the TD5.
What the tester did say is the Disco oil at 15,000Km,was in better condition, than his TD 4.2L Patrol at 3,000Km.[biggrin]
Our D4 was always done at 10,000Km,which is same as every Tojo vehicle i have ever had,although Tojo do say you can go 5,000Km over and it will not affect warranty,and it is written in the service manual.
You sure LR said 20k… that’s not what my old servicing literature states…
10,000km intervals with 20,000k intervals on the secondary oil filter.
ALL metro used vehicles are arduous cycle.
This is what you had previously stated scarry some time back.
The TD5 was brilliant - was more than happy with 20,000km oil changes for city use. But wouldn’t run as tight of tolerances as the TDV6 does.Quote:

Not convinced Australia should have been put in the low-sulphur group from MY12 on.
But I do wonder how many 3.0TDV6 that failed doing 12month servicing were doing more than 15,000-20,000kms between services.
You are correct,i will change the other post[smilebigeye]Quote:

An oil filter that drains back the oil can be an issue though for sure.
As regards extended drain intervals, a lot of this is simply to do with emissions requirements, unfortunately the engine has to take one for the team!
Of course no one factors in the emissions cost of having to build a new engine or car because the old one has failed, due to trying to meet emissions requirements.
The discovery 2 oil filtration system is not to be confused with a normal(any other) car.
Jap diesels were traditionally filthy compared to basically any one else, plenty of (very) late oil changes requiring either removal of the sump, or filling with diesel, running.. Then dropping again due to carbon saturation making the oil like grease.
I've seen a Hilux blow the filter off the block because of clagged oil, that one had plenty of oil pressure but not much flow!
No doubt newer ones are not like this.

Pretty spectacular way to prove that one is a function of the other.Quote:
