Ah ha... I did not know that about 5.0 being purple in tint. So that same principle would apply with coolant I am supposing, distinguishing the difference between DexCool, HOAT, etc?

While I agree with Tiag about the fluid color change system... I mean, I am sure it does happen. With myself, I am the only one who touches my cars, so I know what goes in, and before finding out about 5.0 being purple in tint, it does make me wonder since I use superblue religiously, would I be putting someone life in danger if it came time to sell? I know in the 4.4 I had superblue in it. Then when I did the brake service last year, I changed over to the Supergold. Now even though I drained, bled, and refilled. Some of the dye from the superblue still remained. Actually, when I look, it does have a purpleish tinge to it. Now I know it should technically make green, but then again with the color variant, people could get confused.

I guess I should always change back over to amber or clear before I sell one of my vehicles. Well, I guess won't be a problem into the future since you can't get superblue anymore.
