I have two gals of MB blue coolant I have no other use for. What is the compatibility? My Toyota manual says ethylene glycol, and further states don’t put any additives in it. That’s it, no red green or otherwise. I recently wasted most of my red coolant due a defective radiator, which will go to the recycling yard, but I am tired of spending money on my old vehicle right now. It will have some red coolant in it already that won’t be drained.
