  Most won't have it.  It's been a long time since they used the red 
dye, most is UV now and a really translucent neon green to the naked 
eye.  It doesn't show up well without a light and not much better 
with one than simply looking for oil trace.  The only reason it'd have 
dye is if someone had put some in there previously.
  "If you see oil or dirt sticking to it, you have a leak".  That was  
one refrigeration guy I knew's thoughts on dye.
