The Walmart 5 qt. jug may be at a comparable price. Around here, you can't get all the different weights in the jug size.

And I was off on the slightly higher grade, the 'extended mileage' variety. It's $6.49 a qt. Dropped in last night to buy 6 more. It's not that huge of a savings - if you buy 10, you're paying $60 instead of $92 but I hate buying one or two at $9 plus when I could have got them at $6.

I discovered recently that you can see the current O'Reilly's ad online. The newspaper insert sort of ad. Might need to watch that - like I said, not sure how widespread this particular sale is.
