oil drain with a pump

[gcodori]

I am planning on purchasing some auto-rx to use in my 2001 beetle TDI.

I use a Pela 6000 to extract the oil from the dipstick tube (so i don't have to lift/crawl under).

Will draining through the "suction tube" of the oil extrator get all of the particles that may be in the bottom of the oil pan (not caught by the filter)?

Would it also be better to have the car angled toward the front (front lower than rear) when draining from the top (the dipstick is in front, not on the side of the pan)? I ask because I assume the particles would sink to the bottom, and go toward the end of the pan which was lowest.

Lastly, are there any concerns of oil restriction to the turbo during the cleaning phase? I worry that a bit of residue getting to the turbo or into the engine itself.

By the way, first post for me (and more to come I hope).

FWIW - even though it may seem like a hassle to take the time to get the vehicle on a set of ramps, I still think it's the best way to go about it. You get to change the oil and filter (mine is accessed from below), but you also get a chance to do some inspection for any leaks and other vital areas such as CV boots, exhaust, linkages, etc.

It might be quick and easy to use a pump via dipstick tube, but that's not what I'd consider "thurough".

Others will chime-in with further details.

How to do an oil change on a 1.9TDI with a Pela 6000. From the video I'd say the pump works better than just draining it from the bottom.

I agree with Curious Kid

I was helping a friend change the oil in his Grand Prix. This guy didn’t know a lot about working on cars, aside from throwing on mods. We took the tire off to get to the oil filter, and the wheel well was coated in grease. Someone thought it was oil, but I and many others knew what was wrong. Everything was being flung from the area of the cv boot. Without being under the car, we wouldn’t have known.

The TDI's beetles are designed with the filter on the top...you simply unscrew the cap and pull out what looks like a roll of paper towels!

The pump allows you to change the filter and oil without jacking the car.

I do agree about being able to inspect things (the beetle has an aluminum oil pan which can be damaged by road debris). On the other hand, because the pan is a softer material, you have more changes to strip/cross thread the bolt if you drain from below. YMMV.

The Beetle was designed so you can change the oil, fuel, air and cabin filters without having to go under the car (makes for easy ownership).

In terms of the first question I asked, will the extractor tube pick up all of the suspended particles? How long do they stay suspended before settling to the bottom? The Pela can extract hot oil (no need to cool much, before the change).

My Auto-rx was ordered last night. I'll update everyone how the cleaning goes.

I'll bite. I use Pela 6000. I used Pela 6000 through my Auto-RX clean and rinse (and now maintenance). There is nothing suspended as in 'floaters in a drink' after the Auto-RX has done its job and the engine has had a good run before oil change. If there WAS anything which was insoluble, it would have been collected in the filter.

What I do with the Pela is try the whole thing 3 times to make sure I get all the oil out. The 1.8T has a ~4 qt capacity. With the first run, Pela gets out about 2 lt in no time then slows down. I pull out the tube, let air come in eliminating vacuum, put it back and pump out again. A third time is just for making sure.

Now, if there are metallic particles heavier than oil and sitting in the pan, I am not sure about those.
