streets; I also I drive Fuel tankers and have been doing this for about 20 years.I dont like to talk about my own stupid acts but I mixed the greenish/yellow stuff with the purplelish/blue stuff and it foamed up and the truck started over heating. the nice men at peterbuilt told me that mixing differant color anti freeze was a big no!no! then they flushed the system and put one color back in and low and behold the truck stoped over heating.I also pulled a portable ice rink around the country. we also pumped glycol or anti freeze thru the rubber tubes in the floor to cool the H2O that we sprayed on the floor with a garden hose that would then turn in to ice.for some reason they did'nt want us to mix anti freeze colors in this 300,000 doller machine.good for me but feel free to do your own testing. or talk to the guys at peterbuilt
