The oil that we pour into the engine is wear out in itself, even if the car is calm in the garage - it is oxidized. Moreover, oil wear is inevitable with the active operation of the engine under serious loads. One of the large tests for the engine can be oil starvation - how to avoid it, signs and consequences, and how to determine the oil starvation, find out right now.
Due to the insufficient amount of aluminum lubrication almost melted
The lack of lubricant in some nodes in certain modes of engine operation is theoretically called oily starvation.
For obvious reasons, in the absence of lubricant in rubbing nodes, they instantly fail. Danger oil starvation The motor is that it may occur instantly and almost completely destroy the main engine nodes:
- crankshaft,
- camshaft
- gas distribution mechanism,
- cylinder-piston group,
- other vital and expensive nodes and aggregates.
Torn insert camshaft (due to insufficient lubrication)
In the same way!
In a flat place, oil starvation does not occur And as a rule, all the wines in the breakdown lies only on the owner of the car or motorists who made repairs. As is known, the oil is in the crankcase in the amount needed for lubricant and is supplied to the system with an oil pump. In the event that the oil can not get to some rubbing nodes, oil starvation occurs. The reasons for this may be mass.
How to determine oil starvation
It immediately it was clear that the engine was "hungry oil"
Initially, the determination of the oil starvation of the engine, since the spectrum of symptoms is wide enough - from the drop in the engine power, before overheating, foreign noise and knocks. All this indicates the wear of certain, characteristic of each engine of the nodes. For example, in the most common urgent petrol engines Frequently found accelerated wear and increased noise when operating the gas distribution mechanism.
Effects
The consequences can be the most different - the camshaft is jammed, the breakdown of the camshaft, the flap of valve, the destruction of the valve rocker, the turning of the crankshaft liners, the rings in the sleeve right up to the destruction of the pistons.
In addition, there may be oil-chained rings, which will lead to even greater overflow of oil and engine jamming. SIZY thick smoke from exhaust pipe Just says about the malfunction of the scale rings and high oil consumption.
Causes of oil starvation
Engine operation in oil starvation mode Almost in all cases is accompanied by an increased temperature, which you need to pay attention to. In addition, the oil pressure in the system can be either very low (what will say control lamp Oil pressure on the instrument panel), or unstable. All this may be caused by such reasons:
- Insufficient oil level in the pallet
. Lubricants simply lacks for the processing of all bearings of sliding, the oil film is absent, the details work almost dry. That is why at least once a week, and with active operation more often. In addition, it is necessary to closely monitor the height of the oil and, if necessary, take measures to eliminate the leaks.
Property of oil in the engine (from above the analog, from the bottom of the original). Not true testimony of probe can not specify the car owner about the insufficient lubrication level.
- Using the oil inappropriate . This is very an important pointbecause, for example, oil 5W-30 when used in summer period It may not give the necessary viscosity, the engine lubricant will be insufficient, the pressure at high temperatures may be critical to fall. To avoid this, you need to adhere to the recommendations of the car manufacturer in the choice of engine oils.
- The grid of the oil worker is scored
. Oil pump unable to overcome the resistance of the scored mesh, so the oil cannot be supplied in the right amount and under right pressure to all nodes. It also concerns clogged oil pipelines. An ideal way out of this position is a disassembly and mechanical cleaning of channels and an oil worker, wash products can only make worse.
Mud-mud oil worker
- Irregular or unreasonable replacement Oils and filters
. Each oil brand has its own resource that needs to be strictly observed. Lubrication during operation loses most lubricating properties and by the end of the service life can be almost completely oxidized and losing viscosity.
Disassembly of oil filter
- Wear of oil rings and increased flow Oil . Wear masonry Caps, crankshaft seals will also lead to high flow Oil.
- Poor-quality engine assembly after repair . The competent motorist will never use the sealant where a fairly simple laying is that excessive sealant is asleep not only outside, but also inside oil canals, over time, clogging them.
- Failure reduction valve Lubrication systems.
- Clogging of the oil filter.

findings
As we can see, the reasons for oil starvation can be plentious, and in order to prevent breakage, it is simply necessary to check the oil level from time to time and comply with the regulation of its replacement, to eliminate leaks in time. Then the engine will last long and without expensive repairs. High quality oil and good roads!
I will immediately make a reservation: I treat all kinds of additives to motor oils skeptically. But this, I hope, does not prevent me to reliably talk about what I saw my own eyes and what personally took part. It will be about a single experiment who arranged those who sell the American drug DURALUB in our market. This is an additive to oils or, as manufacturers called it, - metal conditioner.
Sellers argue that one engine treatment with a drug is designed for 80,000 miles of run, during which the improvement of fuel economy is guaranteed, an increase in the resource, confident winter start, a decrease in toxicity ... Check all this in the complex is quite difficult, but ... The fact is that in addition to all other things , The manufacturer declares the possibility of operation of the engine to dry, that is, without oil. And this statement check is easier than simple. Although the motor, of course, is a pity ...
Unlike many oil additives, DURALUB is absolutely transparent and homogeneous (at least externally) yellow liquid.
What is this miracle? The chemical composition of the drug, of course, holds in secret, and consumers represent only the mysterious formula - SR3, the meaning of which (if there is any), is understandable to a little. In promotional materials, the principle of action of the additive is described on the models of molecular friction, but in my opinion, the phrase of the type "ion introduction" or "Positive Sr3 charge is opposite to the excess charge of the crystal lattice of the metal" can only post the buyer, more than once foured by all sorts of "homogenizations", "Turbulents" and "superficial spraying". And those who "lucky enough" also to sort out the motor or choose the wreckage of wonder devices from the intake collers of their car, may even get angry ... But this is all the eryness. Now - serious.
Maski light, plump the oil!
We will give tribute to the organizers of this adventurous experiment: boldly!
For the "slaughter" procedures were provided by two cars: VAZ-2106 and (oh god!) Mercedes 280e. The latter had a revered age and more than 200,000 km of run (of course, with oil). The "six" engine was already processed by the drug, so it was simply conscientiously dried, pre-measuring compression in the cylinders. With the "unprocessed" foreign car entered strictly according to the instructions. First, the contents of the bottle poured into the engine through the oil reform. Then the motor was given to work on idling About five minutes. After that, Mercedes was hoisted on the lift and the contents of the oil crankcase moved to the bucket. Time this process took a little more than ten minutes.
We start the motors. By the way, if your motor does not start, the reason for this may be a starter fault. Solve the problem will help you starter repair price which you will learn on the AUTOKLIMAT.COM.UA website. The oil pressure gauge "Six" was plaintively lit up with a red light bulb and helplessly left the arrow for a "feature of poverty." Pressure - zero. Look in Mercedes. Curling a couple of times, the arrow of the pressure gauge tried was to move the mark 0.5. In vain. I note that before the start of the experiment, the device on this car showed from 2.5 to 3 atm, depending on the revolutions.
Well, let's go?
I was sure that the junction would come here, behind the goal ... five kilometers run, ten. The next Moscow traffic jam remained behind, and we leave for the Moscow Ring Road. Ride cars, go! On average, the speed of 70-80 km / h with the testimony of a tachometer about 3000 rpm.
Well, should finally happen to happen! So I coincided that at the time of the death of one of the engine driving, I was sitting myself: under the load, the engine "six" suddenly began to make a bad metal rokot, which changed its frequency depending on the revolutions. Before the encoding, the case decided not to bring, but simply removed the car from the distance. By the beginning of "agony" his odometer showed 65 kilometers. As an experiment organizers assured, the experimental VAZ-2106 has already had an experience of driving without oil ...
The crew of the second car finished victorious: Mercedes 280e passed without oil 119 (!) Kilometers, after which he was like, it seems to be in full health. In any case, there was no "audible" troubleshooting in the work of the engine.
So was there a miracle?
I do not see a reason to suspect the organizers in the scam. They are great. Well, what did the experiment show? He gave an answer, at least one question. Yes, the drug DURALUB allows car motor It is long enough to work in oil starvation and without oil in general, and its properties are unique. What to say, riding without oil produces an impression.
And yet, those who are already going to run to the store, I propose to think about one more question. Imagine such a situation. Suppose you pierced the oil crankcase or remained without oil because of the poorly screwed oil filter. What are you going to do? I can say one thing about yourself one thing: no matter how the engine of my car is processed, I will search for tractors and cable. If there are concerns that it is meaningless to help on the road, I will definitely put an oil into the trunk before the trip.
Do not forget that the problems of side effects remain beyond the framework of this experiment, which give many oil preparations. Check out this as part of such "frontal" tests is extremely difficult.
In my opinion, the Metal Air Conditioner DURALUB must be interested in the first place those who exploit the technique in the limit, and sometimes in emergency modes. Autosports, for example, it is important, despite the consequences for the machine to get to the finish. Watching, geologists - get to an obscene area. Pilots - put an emergency car. Where the goal justifies the funds. On this while we put the point.
We all know why the engine of our car needs motor oilAnd also understand how important it is to change it regularly. But what do you think it happens if you run the motor in which there is no oil? See detailed video Roller about it.
In fact, the engine without butter is calmly started and even will work for a while. But he will very quickly destroy himself a breathtaking way.
On the left video with the engine in which the oil is 10W-30. On right, .
See the next video video, which is removed using a thermal chamber. This time the author of the video blog shows us what happens with a cheap single-cylinder engine, in which there is no oil for lubrication. For comparison, the movie author also removed on the camera using the thermal imager the operation of the same engine, but only with oil.
Do not forget to include subtitles and their translation
So how many single-cylinder engine has worked without oil before it fails?
Apparently, the experiment lasted about 15 minutes. It is worth noting that 15 minutes later force aggregate Failed without breaking and even clouds of smoke. But, nevertheless, considering that the motor worked a quarter of an hour without lubrication, he received some serious damage that did not allow him to work further.
Recall that if the engine does not have a proper lubricant, all metal components in the motor damage each other due to strong friction. As a result, the engine begins to destroy himself, due to strong wear Internal components.
Unfortunately, most likely, if the engine without oil would have worked in this experiment a little longer, we would have been waiting for a more amazing spectacle. However, this video clearly shows that it threatens the motor in which there is no.
What do you think - can the engine work without oil? What happens to him? Knocking immediately or will it work a little? Suppose you have broken the pallet of the crankcase. What do you do?
It is necessary to immediately say that the engine with these additives will work, but only at idle. On the suspension stands and other engines are specially prepared. All running parts in it inserts, rings are fitted with perfect conjugation.
A small amount of oil allows it to rotate with minimal friction. But it will be impossible to ride on such a car, as it will eat an unreal amount of oil.
Our team decided to repeat the suspension experiment on by the usual engine. That's what we did.
For the experiment, the electronic perfume will help us. With it, we will measure the temperature on the block, the crankshaft, we will see if overheating and what happens to the car in general if it works without oil?
We merge the old oil from the car. To do this, it is very convenient to use the device that you will see in the photo below.
Change oil filter and spin the crankcase cork back.
Pour a new oil and let it work a little in our engine.
We bring the engine and give new oil to lubricate the engine. We are waiting for about 5 minutes.
We drain the oil a new oil, which of course de We will be reused.
We proceed to dismantling the pallet, unscrew the protection on the box and dismantle the pallet itself.
We try to start the motor. Oil light lights up immediately.
Look into the engine. It works without oil. So there is no superstheck and unnecessary! True cool?
In fact, there is one small trick. The engine does not work completely without oil. An oil wedge is present in the engine, which reduces friction force.
Since the engine is preheated, somewhere in an hour a person is suitable with a cup of oil and puts it to the oil worker - the engine sucks oil.
Accordingly, all parts of the engine are lubricated and it can work approximately 30-40 minutes. Such a focus with the cup makes all manufacturers of synthetic additives for the engine. See the photo below.
At the heart of all oils already laid a package of additives that are balanced in this oil. No global oil manufacturer will approve in order to pour any additive there.
It is not known anyone whether this additive will fall out or mixed with oil. On the operating engine on idling Pressure on the oil film is minimal.
Of course it gradually wear out, but with the addition of oil, it is restored again. It should also be understood that the oil helps cool the engine.
