It works very well under the following conditions: 1) the oil must be warm, leave the engine running for 5 to 10 minutes. 2) add a little oil to the extraction tube until it reaches the small motor so it can start suction, otherwise it won't draw. Time for 3.5lt of oil was about 5 to 10 min. As for its lifespan, I have no opinion yet.

The noise it makes suggests that it won't withstand many uses. It is quite slow, it takes several minutes to pump 3-4 liters

It's just fine and even though it's not meant for it, I also pumped water from a car radiator. Overall, for its price, it's an honest purchase!

it works just fine, it takes a little time to pump the lukewarm 5W30 oil and to drain 3-3.3 liters. VFM! for amateurs it's perfect.

The most useless thing I have ever bought. I used it to pump oil from one container to another. It made an incredible amount of noise. In half an hour it managed to pump 1.5L while the description states 3L/min. Where half an hour is the maximum it can withstand according to what's written on the pump, while the description says 20min. It was working as if it was sucking air from somewhere. I checked the tubes and clamps but everything was fine. Obviously, the pump is extremely poorly made. Also, the description mentions that a suction sensor is included and not the spiral tube, while the package contained 2 regular tubes, no spiral and no sensor. (Here I should mention that there is no such thing as a suction sensor as a part anyway, now what they mean in the description, go figure.)

Excellent job for its cost. It drains the oil very quickly. I highly recommend it.

I used the pump to remove coolant mixed with oil from the reservoir of my Opel Astra j due to a problem with the oil cooler! The pump worked perfectly and emptied the entire reservoir without any issues. Perfect product for such emergency problems before taking the car to the workshop.

I am satisfied! In a 2008 Renault Megane 2 with a warm engine, it picked up the oil very easily, all good!!

With a smart and warm engine, it did a very fast job, I was very satisfied.

First of all, because the description says "gasoline", ***under no circumstances***. It clearly states on the box and in the booklet that it is not suitable for any fuel (risk of fire or explosion), nor for water (low viscosity, it will burn).

For extracting car oil from the dipstick, it does its job perfectly fine. You warm up the engine a little or do it after a short drive, you put it in the dipstick and in a large container, you connect it and wait. With 10W40 lubricant, it took me about 7 minutes to drain 4 liters. I have done 3-4 changes without any problem.

for the price of 12 EUR it is good enough... Quality is one class below famous german supermarket's version.
Description is deceiving, it is not suitable to pump benzine (eurosuper fuel), for engine oil extraction it will slowly do the job. If you pour a bit of oil in the pump before first use, it can last much longer. Cable connectors are very cheaply made but the rest is OK. If you pump cold engine oil with it, it will take an eternity to do it, make sure the oil is warm (not burning hot), that will make the process way faster. Fix the output hose properly as it tends to "spit" the oil in the end when pump catches air

Unfortunately, I overpaid for it because I needed it urgently and the only store that had it immediately available had it for 21 euros. However, anyone who buys it at the regular prices here will come out very satisfied with their purchase. I bought it to drain the oil from a Citroen Xsara engine. It did its job nicely and smoothly. Some say it drains with a slow flow. However, the oil should not be completely cold in order to drain it. If it is at 40 degrees, it flows better. And overall, it took no more than 2 minutes to drain it completely.

It does its job very well.
It has a thin plastic tube for input and a wider one for output.
I put the hose on the oil meter tube and it sucked all the oil out of the engine

Decent for its price. It has metallic parts in the pump, so there is no worry about the dissolution of the plastics/elastics from the liquids. The 3 liters per minute for oil do not apply, maybe for fuel. For oil, it is around 0.5 liters per minute, at least with the provided hose, if a wider one is used, it struggles to pull. It easily manages to lift the oil one meter in reverse (with the small tube it has), but it takes time (which is logical)

I saved money on a mechanic. I changed the oil myself with this pump and it worked great!!!! Make sure to charge the car battery well because it takes about 10 minutes to pump out 4 liters of oil.

For the money, it is perfect. I put it on for 10 minutes, the hard rubber on the machine's nozzle, the thick one on concrete. Red + black -, simple to use.

It does its job just fine. It's convenient that it's slow. How long will it last?... Unknown, but it's not for professional use.

Oil change in Smart 451 Cdi where there is no bottom plug to drain the oil. The pump for the money is very decent, it removed almost 3 liters of oil in just over five minutes. Very good job. It also handles other fluids besides regular water because it has salts and if they stay inside, they will settle and it's not very good. Recommended for purchase for anyone who needs it.

I did the first oil change. I let the engine run for 15 minutes to soften the oil since it is winter. The job was done perfectly. In 10 minutes at most, it drained 4 liters. Carefully removing the hoses, nothing got dirty. I collected the oil in 1.5-liter bottles. Very carefully. It is winter and the engine got warm but didn't stop. I don't know what will happen if the temperature is significantly higher. I will come back for the next change.

Very good for careful use, without many hours of continuous operation and with the machine's oil being sufficiently warm beforehand.
