As we all know, Royal Purple has it's purple coloring, that goes away after a couple heating cycles, but that's beside the point. Other oils I saw with color in it is the Liqui Moly Molygen, which was green. And Castrol 0w30, which was green as well. Of course all oils turn goldish after a couple heating cycles, that burn off the artificial colors. But it looks great pouring out of a bottle during an oil change
I wonder what other oils have cool colors other than 50 Shades of gold? List any oils you have seen/used with artificial colors, and preferably something that is still available on the market.
