Your conditions

The oil in the engine loses its properties over time, so it must be changed every 10, 000-15, 000 km. It is easiest to do this in a car service, but you can also save by doing the work yourself. To the happy owners of a garage with a viewing hole, to drain the oil, you just need to unscrew the drain plug in the oil pan. Anyone who does not have access to such a pit can use a pump to pump oil through the dipstick hole.

Just note: such a device will help you out only if you can reach the top of the oil filter, the replacement of which is necessary when filling new oil. If in your car you can replace the filter only from below, the pump for pumping oil will not greatly simplify your work. After all, you still have to crawl under the car.

Before work

В распоряжении «ЗР» оказался электрический насос для откачки масла через щуп с двумя трубками в комплекте: обе подсоединяются к насосу, при этом первая устанавливается в отверстие щупа, а вторая служит для слива масла в емкость. Направление движение масла обозначено стрелками на корпусе насоса

At the disposal of "ZR" was an electric pump for pumping oil through a dipstick with two tubes in the kit: both are connected to the pump, while the first is installed in the hole of the dipstick, and the second serves to drain the oil into the tank. The direction of oil movement is indicated by arrows on the pump housing. At the disposal of "ZR" was an electric pump for pumping oil through a dipstick with two tubes in the kit: both are connected to the pump, while the first is installed in the hole of the dipstick, and the second serves to drain the oil into the tank. The direction of oil movement is indicated by arrows on the pump housing. Already at the stage of preparation for the test, we identified several features of the electric pump. Firstly, our instance was initially inoperative. We disassembled the pump, and it turned out that the electric motor does not rotate, since the mechanical part of the gearbox is screwed to it too tightly. The cause of the malfunction was eliminated - and the device worked.

Secondly, the electric pump does not work dry, so you need to remove the plugs on the holes for the tubes and pour 40-50 ml of oil into the device using a syringe.

Thirdly, the tube entering the dipstick hole has a diameter of 6 mm, while the diameter of the probe tube on some machines may be smaller in diameter. Simply put, not every engine will be able to connect an electric pump. Among them, for example, is the 1.8-liter Lada Vesta engine, on which we initially wanted to carry out all the work.

Paradoxically, because of this, our experiment was only “cleaner”: we decided to drain the oil using an electric pump in the same car on which we checked the vacuum unit for pumping some time ago. This is a Chevrolet Aveo.

Pure experiment

Having inserted a tube into the probe hole, we connect it to the pump. On the other hand, we fix the second tube - to drain the oil. We lower its second end into a 5-liter plastic bottle from under drinking water (a transparent container allows you to control the volume of the drained working fluid). We make sure that the pump is turned off, after that we connect the device terminals to the car battery, observing the polarity.

The pump is placed in the engine compartment so that it does not fall during operation. It can be noted that the device is quite quiet. The pump is placed in the engine compartment so that it does not fall during operation. It can be noted that the device is quite quiet.

Turn on the pump and start pumping. The oil rises through a tube inserted into the hole of the dipstick, passes through the device and flows from the second tube into a plastic container.

After a few minutes, the sound made by the engine of the oil pump changed, as the engine became easier to operate. This means that the oil is over. We will verify this by moving the tube inserted into the probe hole. If the sound of the pump does not change, turn off the device.

Check

To understand how effectively the electric pump coped with its task, we raise the car to the lift and unscrew the drain plug in the pan. Oil flows quite intensely. During our last experiment, when we used a vacuum unit for similar work, this was not the case.

Мы дождались, пока оставшееся в системе масло стечет полностью, чтобы оценить его объем. Набралось почти 200 мл

We waited until the oil remaining in the system drains completely to estimate its volume. Got almost 200 ml! We waited until the oil remaining in the system drains completely to estimate its volume. Got almost 200 ml!

The conclusion is obvious: you should not change the oil in the engine yourself with the help of an electric pump. And although the device is of interest, it clearly needs to be improved.

What's left over

Before draining the oil from the engine, we replaced the oil filter and filled in fresh oil. The result of the experiment did not satisfy us - an impressive amount of old oil remained in the engine.

Despite the fact that the experiment with the electric pump called into question the effectiveness of this device, it is possible to replace the oil in the engine in the garage without a viewing hole. If you use a vacuum unit for this. It costs twice as much as an electric pump (2600 rubles versus 1300–1350), but has two significant advantages compared to it: a vacuum unit that pumps out oil almost completely, more efficient and versatile, as it allows it to be drained from the engine even through a narrow oil hole probe.
