I checked my coolant level in the radiator yesterday and noticed it was a purple color.Is this extended life or conventional type?It actually seemed to have a rust tint also which concerns me at 2200k further more with an all aluminum engine with plastic and aluminum radiator where could the rust color come from?Anyone else noticed this?:confused

Royal Purple has an additive called "purple ice" It is Royal Purples version of Redlines Water Wetter. It is purple in color. Don't know if this helps.
