No doubt you’ve probably seen one of the “oil war” ads ongoing right now. Oil A protects X times better than Oil B. Oil C cleans X times better than Oil D. Etc. Etc. Etc.
Now, Quaker State has fired a shot across the industry’s bow, challenging other oil companies to independent testing in a full-page ad in the March 20 edition of USA Today. (Should’ve spent their money with NOLN, but that’s just me!) You can see the full text of the letter here, courtesy of Jobbers World.
According to an article by Tom Glenn at Jobbers World, comparing the tolerances and performance characteristics of modern motor oil is nearly pointless, as the specifications for motor oil are so strict that even though one oil might in fact protect X times better than another oil, the tolerances are so tight that the difference is inconsequential. Glenn quotes Shell’s Selda Gunsel as saying that “comparing oil against oil rather than oil against spec” is something Shell is avoiding because it’s “bad science” and could be misleading.
