Surely these should be called a "Partial Oil Change Pump".


Paul G
These or something similar are used on boats where you simply cannot access the sump plug even if you wanted to. And a lot of boat engines are bigger & a lot more expensive than the average car lump.
Also in tests they have found no difference between pumping & draining conventionally.

Speed pump?

0.2L/min

That'll be 20 + mins at least then, even longer for cold oil - not exactly 'speedy'. LOL
Why would you change the oil whilst it is cold? Same as pulling a sump plug, start it up & warm it up then suck the oil out.

The ad says "engine oil max 60 deg C 0.2 l/min" so you either have the choice, it takes 20 min or you cream cracker the pump the first time you use it!

Can't you read? wink

When I do an oil change the first stuff to come out of the sump plug hole contain numerous bits, metal shavings etc. The next 90% of the oil looks fine and I sometimes wonder why I'm changing it.

This device will effectively remove the good stuff and leave all the bits on the floor alone to add to the new oil. Surely its the very opposite of a beneficial oil change.
You should never have metal oil shavings in the oil change after change.

I’d be looking to trade the car and procure one without engine issues.

Bang on. I’ve never done a change on a car with a magnetic plug without at least some metallic residue on the magnet and on the much older cars you get more. Even then if you leave the old oil overnight and then pour away there’s always ‘stuff’ left in the bottom of the container.
On some cars you’re dealing with maybe 10-15% of an engines life wear which inevitably will mean particles of all sizes, so I would want to do a proper job plus be alerted to issues. 0.2l a minute is painfully slow too it’s a dribble.

I find it hard to believe the cars I've owned over the last twenty years have all been on their last legs. But if that fits with your understanding then fine. It was only an observation that sucking out from the top is going to leave a bunch of debris at the bottom for the new oil.

Obviously this is a great device for those not worried, or believing that these bits don't exist.

When you think about it, its a bit of a waste to put a sump plug in at all what with the way the oil keeps everything in suspension. Obviously smart is at the forefront of modern car thinking.

I don't know for sure as I do all my own servicing, but as I understand it, some/most/many (delete as appropriate) main dealers use the pump from sump method for oil changes. With the plastic undertrays fitted to modern cars, its getting increasingly time consuming to even reach the sump plug. If method this doesn't work, someone had better tell the big boys.
As I've said previously, I've used one of these Lidl pumps, it drains the sump in less than a couple of minutes, maybe the speed rating is meant to say 0.2 l/s rather than l/m?
I've used it on my Mx5, (battery in boot), just connect the crocodile clips to the incoming lead to the fuse box and any random earth, it doesn't draw a lot of power.

But you said every oil change there are metal shavings.

On the first oil change yes that makes sense hence some cars (BMW Maxes)go in for the 1,200mile oil change but thereafter there should be nothing at all.
If there is then there is something wrong.

Others have pointed his out earlier in the thread too.


Also main dealers use the pump these days far quicker and easier.

Just a thought to counter your thoughts on this.........

You don't suck from the top, the entry point for the pump is at the top, the pump inlet is going to be at the bottom of the sump or it won't get any oil.

If it could sit on the top (even though it don't float) it would just suck air in not oil.

Dipsticks aren’t always at the lowest point and you’ll only clear the immediate area anyway.

Nobody is forcing anybody to use one of these. I don't know why it is such an issue for people what other folk do.

I have one and use it for additional changes over the 2 full services with filters I have per year. I change the oil 3 or 4 times per year.

If anybody has bothered actually researching and measuring you would find in most cases the suction pipe gets almost all the oil from the sump. What is left that drains out if you remove the sump plug is minimal, far less that is left in the engine pipework.

In terms of particles, that is not the only issue. The oil quality deteriorates over time and it becomes less efficient. Additional changes are a good thing in my opinion and a sign that a car has been well cared for.

It's irrelevant, you push the tube into the bottom of the sump and it sucks.

Most manufacturers now have flaps in the tray you can lower down to get in without removing it.

Any metallic residue is so fine that it's actually gone through the filter to be where it is anyhow so:

A. It isn't harmful to the engine.
B. It's small enough to be sucked up by the tube.

I personally don't really see the point of these, but some people seem to like them so thought I'd give a quick heads up.

How does this work then/

Does the clear hose go all the way down inside the dipstick tube to the oil?

Or does the clear hose adapt to the top of the dipstick tube and suck oil through the diptick tube?

If the latter... do all dipstick tubes go down to the bottom of the sump?

The thin clear pipe pipe has to go inside the dipstick tube, and is pushed all the way down to the bottom of the sump.

i never said the dipstick was at a low point, I actually said it is relatively high, but you still need to drop the inlet for the pump to the very bottom of the sump or you don't get the oil out.

Hmm this is my dipstick tube:



Does it poke out the bottom a bit? are those holes in the tube near the bottom?

Suppose I could just crack on and see how much oil comes out knowing how much has drained on previous changes.
