Don't know if it's nation wide but Auto Zone here is selling Valvalene racing oil right now at 50% off. This goes for the dino oil as well as the synthetics. At my store we have dino in 20w50. 50, and 60 weight. No synthetics though. Check out your local store if you want to get a deal for the next 3 weeks guys.:biggrin: Here that means that I can get it for $2.15 a quart.
