has anyone used an oil extractor on their Passat? Strong advice from chaps over on the Golf GTE forum is that I shouldn't tolerate overfilled oil level. As getting it to a dealer is very difficult at the moment (shielding) I tried using a thin plastic tube down the dipstick tube, but couldn't get it down very far. Before going on Amazon to buy a pump, I just wanted to hear whether anyone has had good experience with an oil extractor? Should the tube go into the oil filler rather than the dip stick tube? My car is a 68 plate GTE estate.
