Hi, oil extractors work great. Ive used one for years. matter of fact, Mercedes and bmw, think vw too use them as a factory tool. As far as guys thinking they don't get all the oil is sadly mistaken. Oil extraction gets all of the oil out to the point that there will be no drips. One machine can be used for so many different jobs like brakes, tranny service, power sterring, etc. Try one I think youll like it.
