I can do all of this without a jack, ramps and can do it wearing whatever clothes I want as there is no dripping oil in the process. It cost about $85 shipped from Amazon and I've had it about 2 years. No issues with it so far. Best tool I have in my garage and it is perfect for BMW's that have dipsticks and oil filters on the top of the engine.
Wow, that is really fast! What size compressor, psi and hose are you using? On of my buddy has a mitvac (dont know the model number) and i've seen more than 15 minutes to drain 5-6qt. He is a mechanic and has the compressor set at 115psi. Anyhow, glad it works out great for you. I will just stick to the old fashion way.
