The big main game changer there is engine design - (diesel)- indirect injection vs direct injection. The old indirect engines dump large amounts of soot into the oil, where as the newer direct injection engines are much, much better in this regard.
As an example - my old landcruiser with a 1HZ engine, pushing oil change intervals out to 10,000km resulted in soot levels up to nearly 3% (typically around 2% however)
(bear in mind a 10L oil sump as well)
My D3 2.7 on a 15,000km oil change only has a soot load of 0.6% for a sump half the size. That's a big difference in contamination levels

Robinson Service is big in the US in LR and other Euro marks. This is a good article:

JE Robison Service - Bosch Car Service Specialists ? the blog: Thoughts on oil change intervals and other fluid matters

I dont buy for a minute that so called clean diesels are cleaner than a modern petrol...so why 10,000k for a modern petrol?

Anyway, I have given my opinion and that is all it is. I will continue to change oil at intervals I consider will lengthen the life of the engine. Oil is cheap. Engine replacements/rebuilds are not.

Cheers

The guy's oil advice seems sound but you will note that he is accepting the fact that better engineering is moving away from the old measures ....


However when a guy suggests "replacing the troublesome air suspension to springs" .... in newer Discos .... and suggests "upgrade to Polly Bushes " .... well I guess he knows his oils better than anything else.


Would you let this guy service your D4?

Haha. Yes not great advice on suspension.

The cynic in me says its more to do with waste oil than anything else, its probably cheaper to spec a better (trans fluid) engine oil than pay to have a cheaper one disposed of every 6 months.

Well it's confirmed the crank as broken. Unfortunately the fellow I have been dealing with has had to take leave for a few days so will go into the reason for it on Monday. I have been promised the oil analysis will be emailed to me Monday as well.


It would be nice to work out what has gone wrong so we can avoid it happening again. Certainly if we are spending $20+K on a new engine we don't want a repeat.


I think a lot of you are right. More oil changes!!

Good luck for Monday!

Owning a D4 2.7, I am still wondering why LR decided to make the 3L oil change intervals 26,000 km and yet keep the 2.7L at 12,000 km? They both have the same crank. I can't see how having one extra turbo would warrant extending the oil changes - it should reduce it if anything. Are the injectors and rings really that much better in design to offset the extra turbo? I doubt it.

IMHO, it all points to a marketing exercise (ie. reduced owner service costs) - where LR only have to cover warranty to 100,000 km and the risk to them is minimal. :mad:

For MY10 the 2.7 was 24K and the 3L 26K - very little difference.

Our work Mitsy vans are petrol and we have been changing engine oil at 15k as per manufacturers specs,some did over 300k before they were sold,never had an issue.Many were also on LPG.The Tojo vans are all 10k,which is a PITA.

We were doing a lot of work with Castrol refrigeration oils in the days i had a D2.

I had the engine oil from the D2 tested a few times at 15k,and again at 20k.

At 15k the oil was fine,at 20k it needed changing.

The comment from the tester in the lab, was the D2 oil was performing better and in better condition than similar oil from a GU Nissan Patrol 6cyl diesel,at 3K.This showed how much further advanced the TD5 was compared with the indirect injected GU.
