"* New ashless anti-wear additives combined with ZDDP provide ultimate wear protection"

That screams boron based anti-wear additive with lowered ZDDP levels IMHO. I guess it's VR1 not-street-legal from now on :-) Granted, the non-street legal has about half the detergency, so you can't go very long without an oil change, say no more than 3000 mi with it!

I'll add to the list oils we've run and are happy with, wear-wise:

Mobil 1 MX4T 10w40
Royal Purple Max Cycle 20w50
Amsoil m/c Harley V-twin 20w50

I'm sure there are others that aren't coming to mind right this minute. I use the Brad Penn and Swepco products very happily, and I have a few customers running the Brad Penn in their race cars with excellent visuals upon tear down (356 & 914).

I'll also add the caveat that I don't recommend running Castrol GTX for more than 3,000 mi either. In our field testing, it broke down rather quickly (consumption of detergents, Zn, and P) compared to other oils.

Oh, and I will go as far as to say that if an oil has SM or CJ-4 on it, I wouldn't use it unless you have definative proof that the formulation hasn't changed or has good levels of Zn and P before using it.

For those with water cooled engines, there are plenty of SL or earlier API spec oils on the approved list. I run a Motul factory-approved oil in my VWs- W8 passat and V10 tdi T-reg, since I plan on keeping both past the warranty period like with our Porsches!
