I had the first oil service at about 8500 miles. The car had done 16000 and the oil service indicator stated I had 5100 miles to go before it needed the oil service. My "driving style" hasn't changed and I do do a lot of short journeys so I was surprised that there was going to be such a difference in the mileage between oil services.
The concern came with checking the dipstick and finding the oil level so high. The fact that on checking with the dealer Landrover Assistance insisted on recovering the vehicle shows how serious the potential problem was.
If I hadn't checked the dipstick and relied on the service indicator, I would have driven for the additional 5100 miles and potentially caused serious damage to the engine.
Absolutely correct - high diesel dilution has already caused, and still has the potential to cause, catastrophic engine failures with
potentially life-threatening consequences. Until the Service Required warning system works correctly on all cars, Ingenium diesel engines can continue to fail in dangerous circumstances due to unchecked oil dilution. Just as JLR said they would in JLRP00100. See
Catastrophic failure.
It has been alleged that JLR took deliberate steps in an attempt to hide major design/engineering faults in the 2.0L Ingenium Evoque and Discovery Sport diesels that it manufactured and sold for two and a half years between September 2015 and the early part of 2018. After being exposed on this forum and elsewhere, they've finally stopped trying to hide the problem -
but without changing the architecture and hardware of the exhaust system - and now say that "higher than expected" diesel dilution is caused by the drivers themselves and is a matter of "design intent". I suppose it's a case of picking the lie that you dislike least, because to my way of thinking it can't be BOTH "higher than expected" AND "design intent" at the same time. They have been asked about this in the CRC relations area, it will be interesting to see how they square the circle.
Like other manufacturers, JLR deployed software routines available on the Bosch EDC17 ECU. Some of the available software routines keep AdBlue dosing low in real world driving, thus enabling diesel engines to operate at the higher temperatures which are needed to deal effectively with hydro-carbon and particulate matter production. But on 18th September 2015 the world received unambiguous notice from the United States' EPA that such software devices could no longer be used if car executives also wanted to avoid the prospect of jail time. These software routines are better known as diesel cheat devices. Removing them without changing the exhaust design is known to cause higher oil dilution, intermittent hesitation in throttle response, high AdBlue usage, reduced fuel economy and, in the worst cases, sudden DPF clogging leading to ultimate failure. See the Guardian,
Emissions fix left car undriveable.
Hiding the service interval problem was a necessary deception because the company executives knew that it could have been in financial difficulty without the large income streams coming from these two mass market models. In fact, we now know that JLR was barely breaking even during this period and has only managed to
look profitable for the last three years (FY2016 to FY2018) because it had put at least £3.1 billion of borrowed cash, money that had already been spent, into the assets column of its balance sheet. This is called "capitalised R&D" spending and Tata investors had noticed well before the recent £3.4 billion profit crash that JLR was capitalising an inordinate proportion (80%) of its research and development spend, way higher than the industry average. See my posts in various threads in the Off Topic section for documented history of the financial crisis that was developing in parallel with the deliberate diesel dilution deception campaign.

everybody has been lying since 2015, then JLR has nothing to worry about.
