Vacuum oil extractor

[D2028]

I was thinking of purchasing one to do oil and transmission oil changes (om646 and 722.6). Any one here had any experience as to how efficient they are and recommendations ?

I’ve had a Pela for a few years buddy , good bits of kit, others have the Sealey ones

Thanks, I was leaning down the Pela route, the only doubt I really had was just how much oil/atf would be left in the sump as compared to doing it the traditional way?

I used one of the Aldi ones yesterday to do my oil change, certainly a lot easier than drain plug in the sump

There won’t be any oil left in the sump .
You just need the oil hot for successful extraction

Sounds good, I realise the atf sump does still have to come off to change the filter but this would make the procedure less messy…..I think

I’ve done quite a few atf sump changes on the 5g box in the CLK . I do it every year and only change the sump filter every 40k miles .
Removing the gearbox sump you might as well just use the drain plug for the atf , if you are removing sump to do the filter , after all you are under the car anyway .

Only thing is the drain plug does leave a fair bit still in the pan to make a mess, I was thinking of the extractor removing more than the drain plug before removing the pan and not having to disturb the drain plug at all.

It’s been done before I’m sure . I just wear old oil absorbent clothing and roll around on the floor

My rolling around days are sadly behind me, 50 years in the building trade takes its toll unfortunately. I have learned to work smart not hard, just a shame it took 50 years of hard graft to learn that.

Its a variation on how most MB dealerships service depts drain oil or other fluids. Their design origins are reputed to have come from changing oil in small marine craft with inboard engines for obvious practical reasons! Pela 400 Vacuum Oil Extractor Pump 4 Litre

I also use a Pela, the 6-litre 'tall' version and have never had any concerns about it. If the sump capacity is greater than 6-litres it's easy to stop part-way, empty it and restart.

If I was more cleverer I would follow your lead buddy

I made the mistake of using my Pela 6000 (6 litres) on a cold winter day without warming up the oil first. It took hours and that's not an exaggeration. Warm the oil first and have somewhere to put it. Remember I have a 6000, my car holds 7.5 litres of oil. It does work, though you need to be on hand to pump up the vacuum as it fills, and as an experiment I removed the drain plug after I used it for the first time and nothing came out

Sound advice, I'm seriously thinking of 9 litre Chinese jobby( most things are manufactured there now anyway) as the landrover discovery holds a fair amount of oil.
The thinking is that if I'm not happy with it I could convert the tank to use with my little vacuum pump I got to vacuum test my ac after changing the condenser, it's just sitting there doing nothing anyway.

I have the Sealey one for home use and it works great. As others have said, make sure the oil is up to temperature first and it's all extracted in no time. My engine holds 8 litres, and it usually fetches out every drop according to the scale on the side.

Back when I worked at a dealer and then an independent specialist, pneumatic-aided extraction was the Mercedes-Benz approved method anyway.

I use one of these to drain the sump of my boat's small diesel enIt is essential for the oil to be at a good working temperature.

I use the 9 litre Sealey and find it does the job very well.

Just be aware that the scales on the sides can be inaccurate - especially on the cheap Chinese ones (which work well apart from that). It's well worth filling a new unit a litre at a time with measured water (weighed for best accuracy) and then drawing a new and more accurate scale on the side...

I have a Pela 14ltr and it's been great. Just did an oil change yesterday on W211 E220cdi..6.5ltrs. Keep the oil warm and it should be no problem. I used to do my old 646 and the wife's car in one go..then drop off down the recycling centre. The first time I undid the sump plug no more oil came out.
