Anyone Use a Pneumatic Topsider Oil Extractor?





Now that I think about it, the dealers have been using compressor powered evacuators for many years.
After using the manual version for 15 years, the pumping is getting a little old, and the seals on my manual Mityvac are getting old, too.

The pneumatic drive not only require high-output compressor, but also makes another part to repair.
This seems to be Venturi type pump. Those when are simply build, require huge amount of air. Talk like 3-5 HP air compressor.
I use the smaller tube, and have really tried to get the tube to go down deeper, but with no success. Any recommendations? I'm about to just plan on draining oil the old fashioned way next time.




When I had Mityvac, its biggest tube would fit into funnel end of dipstick tube and holding it there, it would seal.
Bear in mind dipstick tube has small hole on the side for evening the pressure above the oil line, so you will have some gargling.
Than if you really are perfectionist, for the time of extraction you can put a 2x plank under the wheel opposite to corner where the tube enters the engine and then extract oil from filter housing.

I'm not concerned with getting out the last drop, since I go only 3-4000 miles between yearly changes and the oil is not all that dirty with so little mileage.

Knowing that there is at least a quart, maybe two inside the engine even when the oil pan is empty, I've never been one to worry about the last drops either. But I would like to get everything that is in the oil pan.

The C320 took just at 8qts, and on several occassions I sucked out just a few tablespoons less than 8qts.








Have been to Germany years ago and at the time most German cars had recommendation for oil filter replacement every other oil change (dino oils at the time).
So my friend said that with overhead hoses for extraction and oil fill, his VW was in and out in 3-5 minutes for oil change alone.

I did approximately 10 oil changes during my ownership of the C230. I had 3 of those analyzed, one at 68,000 miles, one at 94,000 miles, and one at 133,000. All three times Blackstone labs reported that the engine showed no signs of wear and they recommended me extend the interval to 15,000, stating that the oil had plenty of life left. I was told by Blackstone actually that you do not want used oil to look new, that would indicate it is not doing its job. Used oil should be dark colored.
A bit later we had a 2015 Toyota Corolla that we owned for 18 months and put 41,000 miles on it. The car calls for 10,000 mile oil changes using 0W-20 oil. I had one of these analyzed after 10,400 miles of use. Again Blackstone gave the all clear and said the oil was fine for even longer.
So of course, it if makes you sleep better, change away. But there is no harm in these extended intervals with proper oil and filters.
My W212 is due for oil service this week. I has been 9,400 miles since the last service but the year is up. I may have that analyzed if I still have a kit in the closet. Car has 38,600 miles or so.

If you have hard, scientific data showing that these intervals are OK, I do not understand why people still act like it's unreasonable. It's no longer an opinion when it's backed by data.
