OK, the blue is the same as the green but not when they are different. The pink can be mixed with the red but not the blue except on Tuesdays. Yellow is the same as brown only don't mix it with the stuff that you buy on a Saturday. OAT can be used but silicate can't....except when you can. Question. I've'e got some pink Ethylene Glycol OAT coolant....which may or may not contain silicates. The stuff in the bike is green. If I just flush the system a couple of times and then put the pink stuff in will my engine explode, my girlfriend leave me, and my children want to buy BMW's?
