Walmart had no 0w-20 oils in stock (terribly managed auto oil area).
Advance Auto had Edge and M1 0w-20 products. I'd like to try PP but it's never anywhere on a store shelf. It's much easier to sell it to the public if it was actually on the shelf.
Does Castrol Edge possess any advantages over M1 in this viscosity? I ended up purchasing 5qts with filter 'special' of M1. Edge is $5.99/qt this month, not a great deal, but not terrible these days either.
