I'm not a big believer in Boron in engine oil.
I suspect 99% of the Boron you see in engine oils comes from Boric Acid capped Ashless Dispersants. The Boric Acid improves the seal compatibility of the ashless dispersant (by zapping some of the active nitrogen sites) but ironically this makes it a worse dispersant! The Boron is there as a necessary evil rather than something that makes for a great oil in its own right.
Things may have changed since my day, and I'm happy to be corrected but IMO, a hefty slug of Boron is something to be avoided.
