Well I bought into it and changed all of my oil yesterday and would have to say I do like the idea of getting as much fresh oil as I can during an oil change but...
It turned into quite a nightmare for me. I used the cheap manual pump to pump the oil out of the reservoir and the suction tube ended up falling off into my reservoir

so I got to take the top off to go fishing for that tube which was a pain in the a$$ and added about an hour to my oil change. Than after I finished with all of that and went to put the plug back on I dropped it and it ended up underneath my fuel filter housing so by the time I found it I was out another hour. So after about 3 hours and half a pack of cigarettes all I can say is be CAREFUL…
On the positive side my truck does seem to start up easier….
