I'm not familiar with that extractor but it holds 1 oil change full of oil so that's a good thing.

Yes, oil extraction is easiest, cleanest and quickest way to go. I always use an extractor on mine and have since heard that's the way mercedes dealers do all of them, in fact they are designed to be extracted that way. A recent thread on here posted the mercedes tech procedures.

I have one which holds almost 2 oil change full. I love it.
