There have been many threads in the past about using the Scavenger Oil Change System to do a 100% oil change on your bike, so I'm not trying to open that debate again. My questions are for those that are using or have used this system, or perhaps have seen it used in person. Once you hook everything up and start your bike to begin purging the last of the dirty oil, how fast is the oil actually pumping out into the container? How long did it take until the oil began to flow perfectly clean? How much extra oil did this require per oil change? Previous threads I searched for and found mentioned anywhere from 24 to 32 ounces. Does that sound about right? Thanks!
