now, on another note. do whatever you want. i'm done on this note, there's more than enough info on the web if you're willing and capable of doing so...

You can always tell those that know nothing about motor oil. They often will use the color and clarity of the oil as an indictor of how dirty or how much usage is still there.

Color is very little to do with ascertaining if oil needs to be changed or not.
