I have a Mityvac I?ve been using on the Alltrack, Audi TTS, and a 79 F100. Makes changing the oil every 5k easy. Extracts and dispenses.
Dealership and local shop both do top side extraction, so I figure I?m saving money and using my preferred oil and filter.
I drive around to get oil hot, start extraction, loosen filter, when it?s done extracting, I?ll pull the filter, wait ~10 minutes, extract anything left, new filter, add oil. It takes about 30 minutes total.
It takes awhile to extract, so I?ll use that time to check tires, cabin air filter, clean wheels if they need it.
$100 for extractor, $60 for the VAG cars for oil and filters each change.
O?Riellys takes old oil, so I?ll fill up the oil container with old for easy and clean transport.
