VeryDiscoSport has posted a lot of informative information on oil dilution.
I had my oil changed "under warranty" at 7000 miles after I got a warning showing on In control App.
Still cannot see any service due info on the car menu - only Adblue range. All Topix updates were done.....
My previous cars had oil changed every year and this will happen again of course when it reaches it's 2 year age.
If I keep the car a yearly change will be factored in but worried reading the new dilution thread is this enough ?
Is there a problem with the the Ingenium engine ?
No, it's not Ingenium, it's how and where it is installed. What a very senior technical source acknowledged recently is that full regeneration takes longer on the affected cars than other Ingenium platforms such as XE and XF, which means there is a higher probability that the regeneration process will get interrupted because the "customer" terminates his journey too soon.
Due to hardware and architectural differences, some cars, such as the Discovery Sport, require a "much higher" amount of post-injection to achieve the necessary particulate burn rate and these factors combine to significantly increase the Fuel In Oil contribution for each regeneration event, in turn leading to a faster accumulation of diesel in the oil. When dilution by volume reaches 6.1% drivers of cars which have a functioning SIM message (but not unmodified ones) will be told to go for the interim oil change. If you carry on driving with high oil dilution this will result in engine failure.
Your eligibility for the free oil changes stems from the fact that a clause in the handbook about the effect of your driving style on the actual service intervals achievable wasn't included in the sales and marketing literature, hard copy or internet, that was being distributed prior to 1st June 2017. That is why, and I am sorry to be the bearer of this news, if your warranty commenced after this date, when your car demands an oil change due to diesel contamination before 21000 miles or 2 years, there will be no offer of financial assistance.
Now I don't know about you guys, but I think it's pretty rich to even consider blaming my driving style for something that they are now candidly admitting internally is a consequence of the architecture of the installation, the larger amount of post-injection required to achieve full regeneration, the increased FIO for each event and the resultant acceleration of the amount of diesel getting into the oil.
So, short answer - no, I think the Ingenium is a fine piece of engineering, it's just not being treated properly as things stand.
