Does anyone know of any dyes for lubricants? I was working out of town once and saw that they had all of the different oil types color coded. 10wt was blue and 30wt was red etc. I have asked a few different oil suppliers in the area and none of them have heard of this. I know you can get UV dyes for finding leaks but I do not believe this was uv dye and was delivered to their bulk tanks with coloring added at supplier
