I have been using the Nextgen product for awhile. I think I was one of the 1st persons to post a UOA on it in this forum. I have been re-building my personal oil reserve the past couple of months using the free after rebates (FAR) offered via AAP, AZ etc... on Nextgen. One thing I noticed, and it might be local to may area, is that the date of manufacture on these oil jugs are at least 6 months old. I am assuming these FAR deals on Nextgen are primarily aimed at cleaning out the old stock from the supply chain, but only Valvoline knows for sure.
