So it's been almost two years now, since any input on this thread re: MPG Remedy. My own familiarity on this subject is dimmed by time.
I thought to resurrect this subject as another possible idea to those seeking better mileage. MPG Remedy did have some success for most who tried it. This message thread is huge.
I'd advise anyone who wants to learn of it, to go back to the beginning of the thread. To recap; we were supplied with this idea by Dan Merrick, who was a Gadgetman in the earlier days. Dan is/was a fuel and refineries chemical expert, and brought great expertise to us, if usually in cryptic fashion.
It's a mix of un-coated aspirin, hydrogen peroxide, and alcohol. Dan told us he had used it for years with success. My own experience w/ it showed improved mileage- BUT I found out that I'd mixed it too strong, which damaged diaphragms in the Subie's Weber carburetor, so I stopped using it.
Without re-reading this big thread, I don't recall anyone w/ fuel injection mentioning any trouble.
so, again, if interested, go to the start of the MPG Remedy thread and read into it. that's where the important details are, if memory serves!
