No hocus pocus, the guy who recommended this owned a V8 rebuild shop (no grab-ass, six bays, you drive in with your car at 8:00am and pick it up at 5:00pm with a new V8 in it), used it in his Piper-Cub (next to the twin otter, probably the most sought after light aircraft on earth.) Been made since 1942. Can be used in fuel, crankcase oil, or carb/throttle body. It's just that I recently noticed that it says it can be used in injector cleaning machines, or filling the fuel filter. I'll try it and report back. I usually throw a can in the tank once a month, normally I use Lucas, or preferably Howe's, when I can find it. Usually use it on oil changes, when I can remember it. The other thing I used to use in the engine oil was Molyslip-E (also recommended by the same guy). Great stuff, coats all the metal surfaces with molybdenum disulfide, kinda acts like graphite, will only burn at near nuclear-reaction temperatures (not like PTFE, which turns to hard goop at about 180degC). I can't seem to find it down here though.
