A car has long ceased to be a luxury. Many families today have more than one car, which allows them to make long trips to work, on business trips and for shopping every day. But any vehicle needs regular maintenance, and the driver must know how much oil needs to be poured into the engine, as well as how to add it to the engine.
What is the oil level and how is it determined?
Everyone knows that the level is determined using an oil dipstick.
Its contrasting handle is hard to miss under the hood, and once removed, the minimum and maximum level markings are clearly visible. You can already guess that the engine crankcase is something like a bathtub into which oil is poured to lubricate the engine parts. Obviously, you need to fill it so much that the level is between o and “MAX”, preferably closer to the second. But this does not say anything about the quantity. In addition, the information given in the literature, including that supplied with the machine, sometimes contains strange information. For example:
- amount of oil in the engine crankcase;
- oil filter capacity;
- the amount of oil in its cooling system;
- the volume of oil in the engine when refilling it after repair;
- service volume when changing oil.
And so on. How much oil you need to buy specifically is not written anywhere. As well as details on this matter, explaining what this is connected with.
Application of radish
The plant is a universal green manure, which is characterized by a high growth rate of the above-ground part. With the help of radish, the highest quality weed suppression is achieved. That is why this crop is widely used on virgin lands. This plant produces the highest quality fight against various diseases.
Planting should be done after preliminary plowing of virgin soil. After four weeks after germination, the above-ground part of the plant can be cut off.
To develop virgin land, it is necessary to use green fertilizers. With the help of these crops, not only are perennial plants suppressed on the site, but also the soil is saturated with useful microelements. Thanks to the wide variety of green manures, the gardener can choose any of them at his discretion.
How much oil will leak during replacement and what is the reason for this?
A fairly simple way to determine the required volume. True, it’s inconvenient, since you have to buy oil in advance, unless, like in a car service, its supplies are not limited.
A measuring container is placed under the car for testing, the drain plug is unscrewed, and all that remains is to wait until the stream, and then the individual drops, stop. You can use the scale on the container to determine how much oil needs to be changed. But under one condition - if before the procedure the level was nominal, which means you had to make sure of this in advance by looking at the dipstick.
If the oil was normal, then the resulting value will determine the service volume, that is, the one that needs to be replenished. It differs from the full filling value, since there are many places in the engine from which oil can only be drained by turning the car upside down, which is unlikely to be done during maintenance. How to disassemble the engine. Liquid can remain on the walls of all parts, in the recesses of the cylinder head, in the oil cooler, if provided for by the design, as well as in the oil filter, which is specially equipped with a check valve to prevent it from drying out when parked. The latter is especially interesting, since nothing will leak out of there, but you will still have to add this dose, since the filter will be removed and replaced with a new, completely dry one.
What happens if I pour too much?
On the other hand, overfilling your car can be as much of a problem as too little lube for your engine.
The crankshaft, which is responsible for powering the pistons in your engine, often lies just above the oil reservoir. Typically the pump pulls oil out of the sump so it can do its job.
However, if levels are high enough to come into contact with a fast moving crankshaft, the oil becomes prone to foaming. This airy, bubbling mess is difficult for the pump to properly capture and distribute, meaning the engine won't receive the even, thin layer of lubricant it needs to perform at its best.
What is the replacement procedure
Let's say the required amount is approximately known. For the reasons given above or for more precise information, which will be discussed below. But you should not immediately pour the specified volume into the engine.
- After draining the waste, you need to screw the drain plug back, not forgetting to replace its disposable gasket, if one is provided structurally. The tightening torque is indicated in the repair documentation, so if you do not have significant experience, it is better to use a torque wrench. The fact is that the gasket is usually made of soft metal; it must be slightly deformed by tightening it, but not squeezed out, and certainly not strip the thread. An undertightening is quite dangerous, since there is a risk of not only getting a slow leak, but also generally losing the plug while driving, along with the oil, causing a very fast wedge of the engine with all the ensuing consequences.
- The next step is to change the oil filter. He usually turns away using all sorts of devices, since he manages to firmly stick to his place. But the new one is screwed in by hand, there is no point in pulling it with a wrench, just remember to lubricate the rubber O-ring, it should slide well over the metal.
- There can be a lot of controversy about pre-filling the filter with oil, but there is no particular point in this, it will only waste the outside of the engine. During those seconds of operation at low speeds, while the oil pump fills the filter housing, nothing will happen to the engine; all its parts are reliably protected by an oil film, and there are practically no loads.
- After installing the filter, approximately 0.5 liters of oil less than the expected volume . This is enough to get started. Then the filler neck is closed and the engine is started. There is no need to press the accelerator; you need to keep an eye on the pressure indicator light. As soon as it goes out, this will mean that the filter is full, oil has entered all channels, and the pressure has reached the nominal level. The engine can be turned off.
- After waiting half a minute for it to drain into the crankcase, you can measure the level. The dipstick is removed, wiped and inserted back, all the way, which is very important, otherwise the readings will be false. On the newly pulled out dipstick you can see the oil level, although the product is still very clean and transparent, this will not be easy. Good lighting will be required.
- Based on the results of observations, a decision is made on topping up. Precisely adding to the level, because if you immediately pour in the excess, then removing it without a special tool is quite difficult.
- It is necessary to add based on the considerations that between the minimum and maximum marks there is usually about a liter of oil, although, of course, there is no single standard for all cars. It is better to add little by little, monitoring the process with measurements using the probe.
- At the end of the procedure, the amount of oil consumed will give the final value of the service volume, which will need to be used as a guide in the future.
But this does not mean that you need to buy oil in exactly a certain quantity. Some engines actively consume oil due to waste, up to a liter per thousand kilometers , which is the average threshold beyond which it is time to send the engine for overhaul. Moreover, many of them do this even when new, the consumption is built into the design. Despite the fact that others do not require topping up between maintenance services at all. Mixing oils is generally quite safe, but still undesirable. Knowing that your engine has such a habit, it is better to have a supply of the product that is poured into the crankcase. That is, if the system capacity is 4 liters , buy 5-liter canister.
Separation of lubricants by origin
Today, all motor oils are divided by origin into mineral, synthetic and semi-synthetic. The latter type of oils is very common in the Russian Federation.
Experts advise that when using a motor, strictly follow the instructions for using a certain type of lubricant. Sometimes high-quality synthetics can damage the power unit instead of ensuring reliability and durability of its operation.
For example, if you replace mineral water with synthetics, you may run into trouble. Synthetic lubricant is not suitable for high mileage engines. Instead of reducing wear on the seals, it simply punctures them.
You need to be careful if you decide to choose semi-synthetics for a dead engine. It is better than mineral lubricant, but it is more fluid
This can have a bad effect on internal combustion engines with high mileage. In view of this, if you need to select oil for a worn-out engine, be sure to consult with an employee of the official dealership.
We recommend: Lubricating compounds for guides and calipers - which lubricants are better and why
If you have driven more than a hundred thousand kilometers in your car, you need to pour mineral water into the internal combustion engine. This is especially true for Russian cars. Remember that a worn engine uses a lot of lubricant. Mineral motor oil is inexpensive, so it is an excellent choice.
Semi-synthetics are a combination of mineral water and synthetics. For old Russian cars, its use is fraught with damage to the rubber parts of the engine. This is due to the fact that many aggressive additives are added to this type of motor oil.
Why don't all engines have the same amount of oil?
This is due to many reasons, mainly the size of the engine, its displacement, the nature of ignition (diesel or gasoline), and thermal loads. The oil in the crankcase seems to rest and cool; the more of it, the lower the cyclic temperature, chemical and shock loads it receives. It actually wears out like any other engine part. And the more there is, the longer its beneficial properties will remain. But few people will like buying ten liters of an expensive product every time. Therefore, on average, the service volume of engine oil is about 4 liters . Sometimes it's less, sometimes it's more.
Preliminary search for information
The easiest way to find accurate information is on the Internet. This replacement procedure has already been carried out by many thousands of people, including those who love and know how to give advice. In addition to them, there are numerous sites where such information is collected and classified. You just need to make a corresponding request in any search engine, how much oil to pour into the engine, indicating the car model, engine size and year of manufacture. And don’t limit yourself to one source; you can always find the most contradictory information on the Internet. You should trust large, reputable sites, or even better, repeating numbers in different sources. And look specifically at the volume required when replacing.
Regulations
The plant recommends changing the oil every 10,000 km. The deadline is limited. Many factors influence the deterioration of a lubricant. These include:
- low quality of fuel being poured;
- changing climatic conditions;
- poor condition of roads;
- intensity of vehicle operation.
As a result, you should not wait for the maximum mileage. It is better to change the oil every 8-9 thousand km. If the car is idle for a long time, the lubricant is drained every six months.
What is the danger of an error with quantity?
The probe shows true information, unless, of course, it is damaged. But you shouldn’t fill it “with a reserve”. In the engine, above the oil mirror in the crankcase, there are rapidly rotating crankshaft counterweights. If they start hitting the surface of the liquid, it will instantly turn into foam, which will not be able to work normally. In addition, the motor will begin to “sweat” along all the oil seals and seals. This is not that dangerous, but it is highly undesirable.
Underfilling is even worse. It leads to exposure of the oil receiver in critical situations, such as rolls, acceleration, or simply hypothermia during winter starts. Air in the pump will lead to a drop in pressure and scuffing of the rubbing surfaces. The motor will quickly waste its entire multi-thousand resource life.
The engine oil level near the minimum mark does not differ in any way from the maximum in terms of its effect on the parts. But there is one danger - it is so easy to overlook the moment when, due to waste consumption, it will decrease to catastrophic. Therefore, it is better to maintain the condition closer to the maximum level, it is safer. And carry the reserve in the trunk, but not in the crankcase.
Information about how much oil needs to be poured into the engine is usually required once during the entire operation of a particular vehicle. After the first maintenance, it is clarified, remembered or recorded, and never changes again; the motor cannot increase or decrease its internal volumes. Although there is still one exception - on an uneven road you can run over a stone, from which even the crankcase protection cannot save you. Its thin metal may not rupture, but simply deform, after which the capacity of this oil bath will decrease and the level will increase. You can repeat the procedure for determining the filling volume. But it would be much more correct, without delay, to remove and straighten the crankcase, or replace it with a new one. It’s better not to joke with the lubrication system; engine repairs can cost so much that you’ll have to replace the whole thing, which is also not cheap.
Lack of Oil: Causes for Concern
Engine oil starvation is dangerous! With insufficient lubrication, the service life of the motor decreases much faster. This is similar to a nuclear reaction: wear products are carried by residual oil throughout the entire unit and damage parts that have not yet been touched. Add to this the damage from working “dry” and we get a sad result. If you realize that you have been driving for a long time without oil, it quickly “goes away,” or you notice a strange engine sound, sign up for diagnostics. It may be enough to replace the pan gasket or sealant to forget about the problem. Only a specialist can determine the exact cause.
