If yes, it may help in

Together with FULL ZINC and EXTRA TEN, this combination provides an EXTRA LAYER or DOUBLE LAYER of engine wear protection over normal engine oils at operating temperature. This ADDED LAYER of protection from FULL ZINC and EXTRA TEN improves wera protection and engine longevity.

Looks like Penrite run with a Boron additive booster
only their 10/10th's range with MoDTC in 2 limited cases. One cannot say for sure, without a VOA as to the actual levels and specific mix's of these additives.
Penrite however, do-not use any Ti based antiwear additives. ONly Castrol and 1 or 2 others do (i believe there are some trade secret / patent pending
hocus-pocus going on in regards to it.
If you' looking for a high quality synthetic that has a good blend of both BN and MoDTC, you can't got past Shell Helix Ultra 5W40. It's a 'lite' 40wt that meets A3/B4, SN, BMW LL-01, Ferrari, Porsche A40...
Or for something chock full of BN, Helix Ultra ECT C2/C3 0W30 which has close to 500ppm Boron
It's a 'heavy' 30wt, meets SN, C2/C3, VW504/507. (Works awesome on old Saab turbo's
)
