I have a pella 6 liter extractor and it works fine. Keep in mind some make’s and models are more conducive to their use than others. VW is always easy to do as on most models you simply slip the hose into the dipstick push it all the way in till it stops and pull back about a half inch and it will get most all of the oil out. While the oil is drawn out work on the filter and you are ready to put new oil in.
Some models it is a job to get the hose all the way into the dipstick tube and the dipstick tube location may not place the suction hose at the lowest point in the oil pan. Ymmv.
