All you need for a "stabilizer" is an ounce or two of diesel fuel.
I bought some stuff at AutoValue, before I stopped going there, that was C$16.95 a liter (about a quart). Its supposed to do all sorts of wonderful things like "stabilize" the fuel, clean injectors, "improve gas mileage", seal the valve guides, and whatever.
It smells just like diesel, so one day I put some on a piece of paper and torched it. Lo and behold it smoked and smelled just like diesel. Suspicions comfirmed! I've been using diesel as a stabilizer for years.
So as for these fancy-nancy chemicals - BAH! HUMBUG!
