Still working my way through the 11 jugs of PP 10w-30 I got on end of year clearance at AAP, back in 2018. I have 4 unopened ones left and one frankenjug that has some QSUD 10w-30, some M1 5w-30, and some Magnatec 10w-30, all the unused remnants from previous changes that accumulates in a single jug until I have 4 quarts. I paid $1.65 per jug for that PP. Wish I had gone to even more stores and bought more of it. Nissan MR and QR engines love the 10w-30, they run great and don't burn a drop.
