That poll sums this forum really , your either a happy dreamer or annoyed and dismayed !

No room for people who would prefer the oil service problem to be gone , but at the same time feel capable of living with the problem. its a bit like to old question, are you still beating your wife?


Is it one vote per member or can those with multiple user accounts vote multiple times?

Perhaps multiple sequential accounts or multiple concurrent accounts would be more accurate? :-D

Well my 17MY DS went to nearly 21K miles before the service indicator came on. The 16MY I had until 11K miles and no early service warning. I assume my ‘driving style) was appropriate for the car.
Care to elaborate on that?
Yes my DS’s never had early service warnings. I had my oil tested and dilution wasn’t too bad either. Results are in the oil testing thread somenwhere.
There are far better forums to be welcomed at than this one that locks threads because certain members can’t take a bit of criticism :roll:

Well my 2016 ds has had 3 oil changes and 1 full service in the last 13 months and 20,000 miles of my ownership. It had 11,000 on the clock when I got it

My trustworthy dealer service agent confirmed that 16MY and 17MY cars that got to 21,000 miles without SIM appearing were missing the software upgrade. How many miles did it do before the second service ?

My actual dilution was 1% per 1000 miles and most of that was spent driving at 60-70 mph on main roads. Got the photos, oil sample results and JLR's own ECU data dumps - they don't lie.

The 1st interim oil change was at 15,000 then the service at 21 then again 27 and at 31

It was traded in for a D5 not long after. It had a service warning message. Nothing was missing. The car had all relevant software updates and campaigns applied to it by my dealer. Whenever anything appeared on TOPIx I booked it in.

Yes my DS’s never had early service warnings. I had my oil tested and dilution wasn’t too bad either. Results are in the oil testing thread somewhere.
Actually, the evidence implies that this Discovery Sport had 140% of what JLR consider to be an acceptable level of dilution by the time the dealer finally got round to changing the oil.

The SIM was designed to be conservative so that it triggers at 6.1% by the algorithm, while the real dilution never exceeds 5% - widely considered to be the safe level before an unacceptable risk of engine failure arises. The oil samples where we have BOTH the SDD figure and a laboratory figure to compare it to corroborate this 20% "fudge factor". My first oil sample for example - Millers found 3.4% dilution so 120% of this should have equated to 4.08% in the SDD. It was actually 4.2%, statistically within bounds.

Turning to this car, the SDD dilution counter reached 6.1% "at 13.5K miles" therefore actual diesel dilution at 13,500 miles would have been close to 5%; the equivalent rates of dilution per 1,000 miles being 0.452% (SDD) and 0.37037 (presumed actual). At this point all three counters were reset (because that's all they could do until N025) so thereafter they were useless until the next oil change or A Service had been completed.

Scaling up the actual dilution of 0.37037% per 1,000 miles to 19,500 miles we would expect to see an actual diesel dilution figure of 7.2%. Hey presto! this matches almost perfectly the figure of 7% (no decimal place unfortunately) found by Millers. So this car, while performing much better than the average of 0.67% diesel dilution per 1,000 miles, still only made 60% of the advertised service interval on its first charge of oil and should, in order to avoid the risk of engine failure referred to by Mr. Woodcock in JLRP00100, have had its first oil change at 13.5K miles.

There's no way that, having triggered the SIM at 13,500 miles when 6.1% had been reached, the diesel dilution then remained at the same level for a further 6,000 miles. Indeed, Millers' analysis proved that it didn't. The statement that "the dilution level was under-estimated by the DS" can't be substantiated.

The point made elsewhere about the inferences to be drawn from the Service Poll data is therefore 100% correct.

As for the Iron found in the oil when the oil was finally changed, it doesn't bear thinking about.

So I followed my dealers advice to no ill effects. At 19.5K miles I had it serviced. Anyway. Car moved on.
