For in-store pickup only, Walmart offers the Mobil 1 Synthetic Motor Oil 5-Quart Jug in 11 10 varieties (0W-40 Advanced Full Synthetic pictured) for $22.66. (Amazon is currently price matching a few varieties.) That's the best deal we've seen for these 5-quart jugs since last summer and $15 under the lowest pickup price we could find elsewhere.
