I'm sure glad you guys are around here. Dr Dude just pointed out something I had missed re: preparing the MPGR, adding H2O2 to the asp. first, then adding the alcohol after the asp. dissolves. I had been doing it the other way 'round. Then I tried putting the mix in a heated water bath, which really aided the dissolving of the asp. Plus it usually resulted in the suspension/solution turning purple.
The MPG Remedy definitely works to help MPG results--just that, in my case I was sloppy in my "lab work" with it. It's "acid effect" in my Weber carb's case was too strong for the internal soft parts. I ASSUME it had to be the MPG R causing this deterioration of plastics and flexible membranes. So my take-away from all this is: careful measurements and preparation is essential with it. Doubly so, when used with a carburetor.
Fuel injection systems will be less vulnerable to deterioration, IMHO. My Weber's now solved issues seen to be evidence of Dan Merrick's statements re: the acid in this mix. The effect of fuel seepage at the top gasket line I noticed earlier can be taken as "evidence" of reducing surface tension of the gas. This to me is all physical indications of how MPG R acts in gasoline fuel systems. Perhaps the Anaprin aspirin crystal powder needs a lower dosage by weight or volume, since it's pure aspirin, no fillers. I could have been making a mix several times stronger than Dan Merrick's recommendations. He is a fuel chemist, after all!
Now let me see, where did I put that Uranium powder...?
