Ok, I know you can top off pink with red but you can't top off red with pink. Red is concentrated and pink is 50:50. Pink is not just red diluted with distilled water. I think Toyota switched over to the pink around 2002.
My feeling is that the red is better than the pink and that the pink was formulated to satisfy some kind of EPA requirement or for Toyota to make more money. Note, I said "my feeling." I have read on Toyota forums where some are switching from the pink to the red in their newer models. 2 Toyota mechanics said that's what they do. They say the red is the bomb.
Does anyone know if I could be prolonging the life of my car's coolant system by switching from pink to red? Does anyone know the chemical makeup difference between the Toyota Red and Toyota Pink other than one is concentrated and one is diluted?
