First UOA on new minivan. 15K with the superb VQ35DE engine. LC and FP since new, 3rd interval with Schaeffer's. Wife's van so doesn't see quite the high RPMs the Maxima did (same engine type) but she does get her foot in it a bit. She loves torque just like me
. Just about cured her of "warming it up" for several minutes before blast-off. Thank God for seat heaters.
OK, here goes. Blackstone Labs with the ever excellent interpretation by Terry Dyson.

I'm becomming accustomed to Blackstone's TBN testing numbers and am not really worried about this result. It could probably go out to 7500 before its done. The Si #s are probably some residual engine break-in components as the VQ notoriously wears in slowly. No filtration problems that I can see other than the underhood gets alot of dirt build-up due to its frontal design.
My opinion? I think Schaeffer's is a kick-a oil, especially teamed up with the LC and FP. I'm running GC this interval to see what it does but am glad to have such a good "fallback" oil if the GC produces less than stellar results. Comments please
