Mityvac or similar to vacuum engine oil

Just wondering if anyone has used a Mityvac or similar vacuum device to change the oil on their D3. I know it's used on the D4 but wondering if anyone has used one on a D3.

If so, were you able to remove all the 8 quarts of oil?

I have a vacuum tank that I have used on all my cars. I have a home-made extension tube that was made for my wife's mercedes, but it is not quite long enough for the D3.

So on the D3 I tend to vacuum about 3/4 of the sump out, and then drain the remainder through the sump plug.

I tried it. Measured the length of the dipstick for the draintube but could only get 2 quarts out before it was sucking air. I couldn't get the tube to go any further so I drained via the sump plug.

And you were able to get all the (8qt) oil out on your D3? How did you get the drain hose to go all the way in? As stated above, I could only get 2 quarts out.

It's reasonably narrow gauge but the sump is accessible via the dipstick - if you have a suitable tube.

Copy that. I'll see if I can find a narrower tube than what came with the Mityvac. Thanks for the info!

The smallest I have is 5.7mm OD. What's the OD on the tube you use?

Just under 4.7mm or about 3/16", made by Pela.

Ah, that small OD could be key to getting the tube far enough. I'll have to look for one...

Thanks!
