2009 4Matic Oil Change Lifted vs Leveled vs Extractor
I'm changing the oil at 160k tonight and I'm now confused. The dipstick reading was sitting at 70% (my bad for not checking often or do any topping off). I used an extractor this time from the dipstick tube, it only extracted about 5 quarts of oil and I was extremely worried that I've leaked or burned that much oil over 10k miles.
Being paranoid, I put the car on jack stands (so the car is not leveled) and drained it the old fashioned way through the oil pan drain bolt, it came pouring out. After the dripping became slow, about 10-15 seconds between drips, I jacked the car up even higher and more oil came pouring out. I repeated this until I could no longer jack the car any higher and the dripping became extremely slow/stopped dripping. I used the extractor again to collected the extra oil I just drained to measure the total oil drained. The total oil reading ended up about 7 quarts so I'm relieved I've only burned 0.5 quarts over 10k miles for such an old car.
Now, I'm confused why it drains more when I have the car on jack stands or floor jack. Is my dipstick reading off? Is my oil pan not leveled? Is this why the extractor wasn't able to extract all the oil? I do know that the original owner recently had the motor mounts replaced... could a poor job there cause this?

The OP's car is a 2009 which means it has the same M272 engine. The way to get the entire oil drained is to lift the car at the front and drain the oil since the 4MATIC front axles run through the oil pan which makes it impossible for the extractor to get all the oil out. I've tested this many times.
