Rodger, this is identical, at least the specs and the way they state the degree change, what Im wondering is what eddie said, will the thermo just compensate for it or does it actually run a little cooler, Oh, and if it does, how much does our st take the whole bottle says "between 12-20 quarts" but it says "exactly" the same thing, even the Dx Cool part, might be the same manufact, different brand name..
