Can I mix Sea Foam with ISO-Heet? [SOLVED]

No worries Alexander. Yes, Sea Foam will mix fine with Iso-Heet, which is the isopropyl version.  When mixing petroleum gasoline, Sea Foam, and Iso-Heet, all three are miscible. Miscible means that fluids that naturally mix in even proportion. They also gentle on fuel systems and work well together as cleaners and to solubilize moisture in fuel. Lots of us in the snow belt combine the two when running snowmobiles and small engines during very cold temps to add ignition vapor and prevent fuel line freezing.
