I don't think this is necessarily old stock, and may actually be regularly supplied stock to such stores (the Dollar Tree store down the street from me regularly carries it). In fine print at the bottom of the back Citgo label is a date code for the label revision. I suspect it will likely show a date within the last two or three years, well within the 5 year motor oil shelf life suggested by Shell and other refiners. I've seen old "SJ" oils still being sold at K-Mart, so it's possible that this Citgo is actually NEWER than stock (whatever the brand) at some other chains. And the BITOG used oil analysis for Supergard suggest this brand, rather than being somehow inferior, is equivalent to many other name brand conventional oils. I suspect Citgo's price mainly reflects both a price point strategy as well as the lack of a high-cost marketing campaign, such as with Pennzoil, Castrol, etc.
