By way of comparison & out of interest, since I have a Millers kit surplus from my DS day’s, I am going to send an oil sample from my Lexus when it’s covered 4000miles to see what the various particle contaminants are on a new engine versus those recorded by the DS 4000 miles after the first oil change at 9500miles.

14500 miles done and have just had new oil and filter. Oil dilution at 6.8%. All done on warranty.

Guessing that was the dealer telling you what the SDD algorithm stated and not a full sample oil test that this thread was set up for ?

Yes sorry Barnsh, just what the dealer told me.

In summary;

1. Oil sampled on 30/09/17: Castrol Edge Professional (factory filled) travelled 2540km on oil. Oil & filter changed. Refilled with Mobil Delvac 1 ESP 5W40
2. Oil sampled on 17/12/17: Mobil Delvac 1 ESP 5W40 travelled 2408km on oil. Oil & filter changed. Refilled with Mobil Delvac 1 ESP 5W40
3. Oil sampled on 29/05/18: Mobil Delvac 1 ESP 5W40 travelled 5212km on oil. Oil & filter changed. Refilled with Mobil Delvac 1 ESP 5W40

The DS is mostly driven around urban roads, with very few highway trips. Most journey’s would be under 15km, with fuel usage showing 9.1lt/100km after 10000km.

A heavier weighted oil seems to hold up well, and I’ve always had good results with Mobil Delvac in the past.

Thanks

That looks like an excellent result. Use of the 5W40 probably invalidates the warranty (if they wanted to be awkward) but what the hell. I would rather have low dilution and low wear metals any day. Have you thought about writing to JLR with these findings?

That oil you are using is very thick, about 4 to 5 cSt (that's 40%) higher than the standard Castrol 0W30. Are you still getting reasonably good fuel consumption?

That's three oil changes in 6,000 miles :o
Can I ask why you're changing oil so often? I thought I was bad changing it every 6,000 miles.
TBH, at that rate of replacement there's not really a chance for contaminants to build up no matter which oil you use, and the poor result for the first sample could just be a new engine running in.

NDS,

With regards to fuel consumption, after approx. 10,000km (6250 miles), the average fuel consumption is showing as 9.1lt/100km (31 mpg I believe) from mostly city/urban driving by a female.

I’m not sure if this consumption rate is higher than what others are getting, but I would assume it is. There is no doubt that manufacture’s use thinner oils to aid with better mileage rates.

Mamil,

I've always completed a very early oil change on new engines as I fully understand that there will be a potential for significant wear during the initial run-in period as things bed in. I've also been a stickler for doing 5,000km oil changes, especially for turbo charged engines, which relates to about 6 months of motoring for us. If I was doing a lot more highway driving, I wouldn't have an issue with extending the drain interval to 10,000km (6250 miles) like you seem to do. I was never sold on the DS due to the 34,000km/2yr (21000 mile) service interval claim as it just reeks of BS. The purchasing decision was based on fulfilling our lifestyle needs.

I find diy oil changes are generally simple, with the DS being by far the easiest vehicle I've had to deal with (no ramps required, top mount oil filter which is mess free, replace the OEM drain plug with a ‘EZ Oil Drain Valve’ with a 25mm extension & 90 degree elbow and these changes can be done in under 45min and less than A$110.00).

What was worrying to me, was the constant reports of high wear metal rates in this thread, especially Fe, and as you stated, was this due to the initial wearing in process or was it oil related.

By conducting the two oil changes at equally short mileage duration's at the start of the engine’s life (during the break-in phase) using different oils could provide an answer, especially if you then compare it to a third sample which was used for double the distance of the first two samples………….

My personal opinion is that, 30 weight oils are too thin, use oils that are marketed towards diesel engines as they have more protection additives then mixed engine oils (I even use Delvac MX in my modded WRX), and that an initial oil change at a very short distance in the infancy of a engines life to flush out the break-in wear material is the key.

If the idea of oil testing is to rectify/raise a concern, then the only way a change will be seen is if different oil types are sampled, or the drain interval on the OEM oil type is altered to provide a result that is seen as acceptable.

Thanks

You will also get away with thicker oil if you have no real cold climates to endure.
Thicker oil increases oil pressure , so one to watch out for , it won’t circulate as quickly as a thinner oil when the engine oil is cold.
You’d need to be aware of higher oil pressure on oil seals , although to be fare it’s not much of a difference in warm climates .

I’d be concerned if this was a climate where you have several months in the negative area and lots of cold starts.

Latest sample tested. Total mileage 14000, 6570 on this oil, recommended change at 8000 by Millers. The oil service counter on the car has dipped below 2k so expect another couple of hundred miles at most before I get the service warning message. I've only had a handful of interrupted regens on this oil and a single 'drive for 20 minutes' warning at 13500 when I was driving over Woodhead Pass. It'll be interesting to see what oil dilution figure the dealer comes up with I take it in, the algorithm is obviously way out given Miller's result.
