Snopes is good for shooting things down, but their was no reference to a particular study that disproves the benefit of acetone. Only general references to "studies". Who did these studies? Oil companies or some testing company paid by a oil company? I would trust these studies about as much as the studies that showed Viox Celebrex and Advantia to be harmless. Also the video was clear that he used 2 oz. with 10 gal. of gasoline. I will definitely give it a try.
