Ok, my Humungus Machine is based on a 1984 Ford F150. It needed radiator fluid, and I poured 3/4 of a jug of the new orange stuff in there. Being an '84, it probably had the usual green stuff. I thought I had heard that you could mix the two fluids with no problem. But then a buddy tells me no; mixing the two will rot your seals. So does anyone know for sure?
