Dated from 2013, this datasheet covers the 10w30, 10w40 and 15w40 "Engine Armour" products from Valvoline.
Of interest is that all three grades are definitely on the higher end of the acceptable range for their viscosity at 100ºC, particularly the xW40s on offer. The 10w30 is naturally heavier, given it carries the A3/B4 specification.
TBN of 7.2-8.2 seems a little low for oils carrying the A3/B4 specification, which should allow for long drains.
I still haven't gotten my head around NOACK, so no commentary there, and the HTHS information is irritatingly absent, although a min. of 3.5 is expected given the ACEA approval.
