At KMart today I saw Pennzoil Platinum (some with Pure Plus, some with previous packaging) for $23 for a 5 quart jug. The individual quarts were less than $5 a quart if I remember right. Some had the fuel rewards stickers on them. May not be the best deal ever, but I haven't seen the new Pure Plus for that cheap yet. Hopefully that is helpful to some.
