How can you tell if the water has oil inside? My water is black but to be honest i have never flushed it. I tested by touch if it is oily but it looks just as normal water (ecxept the colour ofcourse) I opened the rocker cover few days ago and i didn't see any mayo at all either.
Also if you have oil in the water does that mean you have water in your oil aswell?
