Walmart next town over had two jugs of Pennzoil Ultra 5W-20 at $21, picked up those, they also had 5w30 however, while I could use that in the IS250 [and it's actually spec'd for that year as they didn't back-cpec until 2010], I figured I'd leave the 5w30 for someone else as I can pretty much use the 5W-20 in all my applications. Tag was up for Pennzoil Platinum 0w20 at both Walmart however none on shelf. Looks like the tags were dated week 2/25/13 so maybe they did their shelves before they actually got product in; there were a lot of new tags up for oils I'm not used to seeing there, but of cours product not on shelf yet. The Pennzoil Platinum was marked at $22. They also has clearance G-Oil at $21 also, 5w30 flavor, 4 jugs.
I scanned a bottle of Quaker State Ultimate Durability 0W-20 at the Walmart in-town and it was still 20.97; this is my go-to oil so long as one of the two Walmarts near me stock it [Walmart in town had tags up for both Quaker State Ultimate Durability and Pennzoil Platinum in 0W-20, the one next town over only had tags for Pennzoil Platinum 0w20]. Otherwise it will become Pennzoil Platinum 0w20 if it stays $22.
