Wear isn't terrible, but the Al uptick is perplexing. Other parameters not bad either.
I don't really know what you'd run a syn at those short OCIs ... The fuel dilution is the issue here; no syn is going to stop that.
This rig accumulates a lot of miles; probably will have 40k in a year's time? Question is this: what kind of service does it see? If it idles a lot, that would explain the dilution from (likely) frequent regens. If this rig hauls loads on open roads often, coming up to temp and staying under load, then I'd worry about a leaking injector.

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...
