That is never going to be a problem on any engine. You can overrun the engine oil change by a good margin.
I am not familiar with this new process. I would be interested to learn how they hone it afterwards applying this layer. The honing proces is likely to give some idea about longevity as well.
I wonder why they call it mirror coating? The inside of a cilinder liner is never mirror like. If it is, it is a sure sign of profound wear. (Like ai experienced on the liners of my Alfa Spider). Cilinder/liner walls have a honeycomb type of mess honed into them for proper oil distribution and oil adherence. I wonder if Nissan does anything different here?. My first thought the naming is a PR trick.
0,2mm thickness might not sound much, but in terms of (car) engines it is a lot. Because of course for the diameter you need to double it. 0,4mm wear on cilinder diameter is a lot!
There have been other ways to improve the longevity of cilinder(liners) whilst still maintaining and improving engine efficiency. It has also been done with coatings before on normal production cars/engines.
The so called Nickasil layering from the late 80/90s springs to mine as used by Jaguar. Turned out to be a disaster in combination. With certain fuels. But since, I can’t recall any problems with liner coatings.
But given this is a Nissan I would not worry at all. These guys know what they are doing. How often do you see a Nissan broken down by the side of the road? And you have a brand new car, covered by warrantee.
Would be interesting to hear from a member who has some more knowledge of this process.
Enjoy your new car
