If you're going to check the operation as you describe, why bother with the extractor?

How do we know if it was or wasnt?
I am planning on buying an oil extractor for my GTI. With the extractor I would not have to go under my car at all. My car holds 5qts of oil, so I will just know if I get close to that out, then I am good.

Do these 2 tests:
1. Drain old oil via drain plug, reinstall drain plug after finish, using oil extractor to see if you can siphon any more oil via dipstick tube.
2. Use oil extractor to siphon oil via dipstick tube until it's done, remove drain plug to see if any oil coming out of it.
If you get some oil with test 1 and no oil in test 2, then the engine is designed with an oil extractor in mind. Someone in a MB forum tested both methods in a 2000 E-Class and the result was oil extractor did better than drain plug.
I believe Mercedes-Benz dealers using oil extractor(much more expensive than average DIY can buy) to do oil change.
Exactly. I did this test on my MB and pulled the drain pan. Extractors work well.
But pulling the plug, IME is just faster and easier. Sure, no lifting or ramping cars if the filter is topside, but I like to be able to look under the car too...
