I'm not familiar with this engine series; don't have data on it. I assume since you posted this in the diesel section, it is diesel. Is the oil there diesel rated? In the States, we think of "Synpower" as a PCMO. But the product you have may be different than ours.
Seems to shed a wee bit of Fe, doesn't it!?!
Interesting jump in Si; did you change or alter the air filter? It's still low enough to not cause concern; I wouldn't really think 9ppm is that bad for almost 18k km.

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money
