Hello everyone,
I did drained motor oil analize (3.0 supercharged 380 h.p. 2016.) and surprisingly for me I have seen a pretty big number of Nickel in the chart.
So could someone explain me what is being worn in engine made of or coated with Nickel. But don't say it is from cylinder walls coated with Nikasil.
Any thoughts will be appreciated.

 

Could be bearings .Can you post the entire analysis?

 

 

not entire, metalls only.

 

Compared to the analyses I have from Blackstone Labs, your aluminum and iron are also high. Nickel has never shown anything other than zero for me and even my break-in oil change at 5900 miles only showed 17ppm of iron. The highest aluminum I've ever seen is 4ppm.

An important piece of information you've failed to provide is the mileage on the oil you analyzed. Another is the type of oil.

 

Yeah, so the laboratory highlighted Ni as unusual.

 

Based only on my own analyses I'd agree that it's unusual, and that Al and Fe are higher than I'd like for my own engine. I don't think there is nickel in the bearings. I'm not sure why you said to not say nikasil, but have you considered that it might be nikasil?

Without the full report and background, it's all guesswork.

 

Despite of Nikasil coating is based on Ni binder, I am not considering nikasil because these engine blocks have been discontinued long before (approx. not later 2002) the car I own was assembled.
It would be a fate if a car of F-type made in 2016 wiil get such an engine.

By the way, do you have nikasil engine block?

 

If nikasil was not used for 2016 models, then it's safe to say I do not. It's not something I've thought about, but only mentioned it because you raised the subject (without explanation).

I know of no other common source of nickel in engines, so perhaps you should be looking at why your iron and aluminum levels are also high.

 

Sounds like you may have a crank or camshaft issue, never heard of nickel being used anywhere else, though I could be way off.

 

Here is a Blackstone oil analysis report from my 2021 F Type R. It was taken from the factory fill oil at around 2750 miles. It showed zero PPM of Nickel. The Iron and Aluminum numbers were inconsequential as the engine was still wearing in. The column on the right shows "universal averages" of each material from Blackstone's testing of other JLR 5.0 liter V8's. As the engine blocks and other components of the V6 are the same, the averages for those engines should be similar. Nickel is non-existent, at least for the way Blackstone does their analysis.

Also noteworthy are the numbers for Molybdenum and Titanium compared to the universal averages. The specially formulated for Jaguar/Land Rover Castrol oil has high levels of those materials so in my opinion it is a good idea to choose motor oil that is equal in formula. I had a sample tested of the Castrol Edge 0W-20 VW/Porsche 508/509 approved oil and it was virtually identical to the JLR approved oil.

 

Are the results on a 16,000 mile interval?
What oil was used?
How many intervals have you tested to get a trend line?

 

The early XK8/R 4.0 units had nikasil-coated cylinder linings but there were a spate of issues with those (probably people starting engines and not allowing them to reach operating temps before switching off so the coating was compromised) so Jaguar dropped the concept.
