Why do you need to change the oil filter? Is it possible to change the oil filter without changing the oil? Changed oil but no filter

If motor oil do not change for a long time, then you can "kill" the engine. Therefore, it is worth discussing how to change engine oil, what is the replacement interval and why they put a new one. oil filter.

Engine oil change various brands the car is not much different and follows the same pattern. First choose suitable oil by type and brand of engine. Next, warm up the engine to operating temperature. If warmed up, then wait a few minutes so as not to burn yourself. Then we find a suitable container where we will drain the waste liquid. An old canister will do if you cut off the side cover with a knife.

Next, unscrew the plug on the crankcase. Typically, this is the most low point on a pallet or refer to the instruction manual for more certainty. We unscrew the plug with a wrench, and at the end with our hands, because the oil will pour immediately and quickly (substitute a drain container in advance), otherwise drain plug lose. The oil drains quickly, usually no more than five minutes. But 100% merge will not work. It's not scary, because. usually no more than 2-3% of the old fluid remains in the motor.

The old oil is drained, the color is evaluated, the presence of impurities. These factors determine whether an engine flush is required or a replacement without a flush is necessary. After, a new one is poured, the oil filter is changed. This work has been completed.

When pouring oil, constantly monitor the level with oil dipstick- it must be between the "min" and "max" marks. Pour 80% of the total volume and then top up, adjusting with the dipstick.

Replacement interval

What is considered difficult? These include: frosts, frequent temperature changes, humid climate, high dust content of the air. Frequent motor overloads (for example, in mountainous areas or when transporting heavy loads) also do not contribute to maintaining performance. Usually, if driving conditions are determined to be difficult, it is recommended to reduce the mileage before replacement by 25-30 percent.

The operation of a car in the city is equated to heavy - a sluggishly flowing traffic jam kills oil as actively as off-road, driving in the mountains or motorsport. Average replacement times: 5000 - 7000 km for "mineral water" and 10,000 - 12,000 km for "synthetics".

Does the oil filter need to be changed?

If you change the filter yourself, do not forget to fill it with oil up to about half the volume (for a better “first” start) and lubricate the rubber on the filter housing.

2. Do not abuse "express" substitutions. Vacuum replacement is bad because much more used oil remains in the engine than with a traditional drain replacement. Therefore, we alternate this method with the traditional one, while reducing service interval or abandon it altogether.

3. Change your oil more often! No one air filter will not retain all the dust and dirt that are present in the air. Accordingly, none fuel filter will not retain impurities that are sold at gas stations along with fuel as a free bonus.

4. Do not use any additives and engine oil additives! Additives can do harm, the positive effect of such impurities is short-lived (what kind of additives are there).

5. Watch the oil level according to the marks on the dipstick. Underfilling to the bottom mark can lead to oil starvation of rubbing parts, which will lead to their rapid wear. Overflow also adversely affects the operation of rubbing parts. What to do if the oil is overfilled.

6. Do not buy oil from dubious sellers! 100% fake products will not meet the manufacturer's requirements, so the motor will fail quickly enough. Buy only original at branded gas stations or find the nearest store that sells reliable products. Metal canisters also serve as protection against forgery.

Why, you ask, is it necessary to change the oil filter, because you can just add oil to everything, and the filter, one way or another, will do its job. And in general, as some people think, calls to change the oil filter are a matter of notorious marketing campaigns in order to extract as much money from consumers as possible by increasing sales. And since it didn't fall apart, it means it works!

The motor is the heart of the car. It is subject to wear and tear like no other component of a car, so taking care of its health and protecting it is the responsibility of every car enthusiast. The fact is that the oil pumped through the filter contains small foreign particles that are by no means unsafe for engine operation. If the oil filter has served its time, then such impurities are in lubricating fluid way more. As a result, the oil quickly becomes unusable, and the engine wears out faster.

As a rule, the filter should be changed along with the oil, however, since the condition of the filter cannot be checked visually, motorists often neglect to replace it.

The oil gets dirty all the time. The filter cleans it from foreign impurities, thus extending the life of the lubricant. But he can't do it forever. The fact is that his work cannot be measured by the kilometers traveled. Your engine is running frequently idle move, thus, the entire load of motor hours falls on the filter.

To date, in retail very rich choice oil filters. If you do not know which filter to buy for your car, then you will choose it from the catalog, or they will offer its cheaper analogue.

Which oil filter to choose?

Filters are not chosen for visual appeal. The most important thing is the material from which the filter element is made, and you pay not for the brand, but for what it consists of. If you are an “aggressive” car enthusiast, often driving a car in sharp start / stop mode, then you are better off taking expensive oil filters. That is, for fast acceleration, fast driving and hard braking, you need more oil to be supplied to the engine. The elements of such filters are made of synthetic material, which tolerate loads and high temperatures well, allowing the oil to pass through it faster. Filters of analogues mainly consist of a cheaper one - a felt element, which can not pass lubricating fluid so quickly. This kind of filters are more suitable for lovers of a calm and stable ride. Thus, if you are not a supporter of “You go quietly - you will continue”, then do not skimp on expensive filters.

The design feature of the car is represented by the contact of all elements and their friction with each other. Metal elements soon appear in the oil, which can disable the entire system if the need is ignored. timely replacement filter element. It is he who detains up to 96% of such impurities, pollution and soot. How to change the oil filter different ways, it is worth considering each of them.

Replacement frequency

The frequency with which it is necessary to replace the filter device is directly determined by its manufacturer. The standard period is every 8 - 12 thousand km. If you have any doubts about the effectiveness of the oil filter, more than frequent replacement.

The cost of the filter is much lower than the cost of a new engine, so it's better to play it safe and follow these recommendations:

• the use of a filter that is not compatible with the brand of your car is prohibited, otherwise important functional units of the power unit may fail;
• since each car has its own characteristics, you should choose a filter device taking into account a certain amount of pressure for which it is designed.

Oil filter replacement instructions

Determine where the oil filter is located first. Its location depends on the design of the engine and on the manufacturer. There are both top and bottom locations, but often this is the front area of ​​\u200b\u200bthe engine of its lower part in the case of front-wheel drive cars.

Lateral left-hand or right-hand arrangement is often found in the case of rear-wheel drive vehicles. Placing the filter directly under the hood contributes to its comfortable maintenance to the greatest extent.

Before proceeding with the replacement, it is necessary to prepare the necessary consumables and tools. First of all, you will have to buy a new oil and filter, be sure to focus on the relevant requirements of the manufacturer of your car.

You will also need the following:

• funnel and pan for draining the oil mixture;
• a special puller, since it is sometimes difficult to unscrew the oil filter;
• head and knob, which will be needed when unscrewing the drain neck;
• rubber gloves are required, they can protect the skin from contact with engine oil.

Preparatory work

Preparation is a mandatory step, so you need to follow these steps:

• installation of the machine viewing hole and activation of the hand brake;
• disconnecting the wire in the battery;
• preparation of the previously mentioned tools and materials;
• cooling the car (without it, the replacement master may get burned);
• installation of a spare tank on the floor to prevent oil contamination of the surface.

Cassette filter or cartridge

Since machine engines use different types filters - cassette and prefabricated, it is worth considering the technology of replacing the former as they are losing popularity and are considered obsolete.

1. Before installation, make sure correct position sealing ring that comes with the purchased cassette. The seal must be on the inside edge.
2. Pre-treat the surface outside with new engine fluid.
3. The cartridge should be screwed back into the crankcase by hand, preventing the latter from coming into contact with the sealing ring.
4. Next, you need to perform another three quarters of a turn to tighten.

prefabricated filter

The process is a little more complicated, and the sequence of actions is as follows.

1. Open the drain plug so that the old oil flows freely into the previously placed container. Expect a complete drain.
2. Use a clean cloth to clean the valve. At this stage, it is worth replacing the washer with a new one and returning the parts to their places.
3. Remove the old filter. Since it is necessary to remove the oil filter with the utmost care, this step should be carried out carefully. Unscrew the element, remove the remaining deposits from the system, check the condition of the seal.
4. Install a new oil filter, it is very important to fix it securely.
5. Locate the neck located on the cylinder head, use a funnel and start pouring fresh oil. Do not rush, use a measuring container. If your vehicle belongs to the category passenger cars with a capacity of 90 - 130 liters. s., 3 liters of oil will be enough, but it is better to play it safe and find the relevant information in the manual. Use a dipstick to check the oil level. To make the indicators as reliable as possible, wait until the engine fluid has completely drained into the sump. Be aware of the viscosity and thickness of the oil, it does not drain as quickly as water.
6. Close the cap to prevent leakage, start the engine and wait for the power unit to idle for a couple of minutes.
7. It is quite normal if the system does not immediately recognize the presence of new oil and the corresponding light flashes. Give the car time. If motor fluid was not enough, topping up the next portion should be only after the engine has completely cooled down.
8. The next few days after changing the filter, check the place where the car is parked for oil stains to make sure there is no leak.

Changing the filter without draining the oil

Changing the oil filter without changing the oil is relevant in the following situations:

1. Installation of a defective oil filter, detection of significant violations in its functionality. Most of all, the driver is upset by situations when problems are discovered immediately after a recent oil filter change. Lubricant is available inside the engine, so it can be used for some time, but changing the oil filter under such circumstances is mandatory.
2. The driver forgot to change the filter when changing the engine mixture.
3. There is an urgent need to change the oil fluid, but a new filter part has not yet been purchased or its delivery is late. In such a situation, the filter device is installed on the car after the engine oil has been replaced, so there is no need to drain it.

The key problem that craftsmen may encounter when performing this procedure is the loss of too much oil flowing from the engine. Against this background, many drivers have a strong opinion that with this method of replacement, buying a large amount of oil is mandatory.

In fact, careful actions and strict adherence to the instructions will save you from such waste.

Ideally, increased oil loss should not be observed. How much oil was in the oil filter, so much will be lost - about 200 ml. As for the step-by-step actions, the procedure is as follows:

1. Place a container under the oil filter beforehand, as its housing will lose the engine mixture during dismantling.
2. The valve cover plug does not need to be unscrewed, otherwise more engine fluid will leak.
3. Gradually unscrew the filter element. First, unscrew to half, wait until the oil drains and remove the part completely.
4. Treat the sealing gum with oil, the same as inside the motor.
5. Start installing a new oil filter, do not forget to check the level of the oil substance.

If you carefully drain the liquid that will flow out while removing your obsolete filter, many people think that you can pour it back into the power unit, but this kind of saving is unacceptable. Pouring drained oily liquid can lead to serious damage, because in the process of leakage, contamination from the outside enters it.

Still, it is better to replace the filter at the same time as the engine fluid.

In addition, both elements have approximately the same operational life. Additionally, it is worth changing the oil filter in addition to a regular replacement, taking into account the mileage, if the car is completely new, and also after a major overhaul of the engine. This recommendation is due to the fact that the engine parts at these stages are actively rubbed in and frequent filter replacement will only have the best effect on the durability of the functional units of the car.

The need to replace the oil filter without changing the oil can arise for many reasons, the main of which is carelessness. For example, after flooding lubricant the motorist recalls that the oil filter also had to be changed. Is it possible to get out of this situation with the least losses, let's see.

Dismantling the old filter device

The need to change the oil filter without changing the oil arises in such situations:

1. The new oil filter turned out to be defective, violations in the operation of the filter element are noticeable. It is especially unpleasant when problems are discovered after installing a new filter product on a car. In this case, there is lubricant inside the engine that can be used for some more time, and the filter must be changed.
2. The moment for replacing the engine fluid has already come, but it was not possible to get the necessary oil filter. For example, the filter is ordered, but the delivery is late (it is not possible to put a duplicate product). After the delivery of the new filter device, it will be necessary to install it on the machine, and there is no need to change the oil.
3. Carelessness. When changing the engine mixture, the master forgot to replace the filter device.

The main problem that occurs when changing the oil filter without changing the engine mixture is the possibility of a large amount of oil leaking out of the engine. Many motorists believe that by performing the above procedure, you will have to buy a large amount of lubricant. This is an erroneous opinion, if the replacement procedure is done correctly, then you can get by with minimal loss of oil.

Replacement procedure

Changing the oil filter without changing the oil should not occur with large losses of the engine mixture. Car oil flows under the influence of gravity into the crankcase. The crankcase is located below the installation site of the filter barrier. Therefore, the loss of the lubricant mixture is possible in an amount equal to the volume of liquid in the oil filter itself. It's about a glass.

The procedure for changing the oil filter without draining the engine mixture consists of the following steps:

1. Perform the removal procedure on a cold engine. Otherwise, you can get burns on your hands, hot motor fluid. If the vehicle has been driven and the engine has warmed up before performing work on replacing the filter element, let power unit cool down, it will take about 40 minutes.
2. So that when changing the filtering device, the car oil flowing from its body does not stain the engine and other elements of the machine, substitute a small container to drain the liquid from the filter.
3. Do not unscrew the plug valve cover: More lubricant will leak out when the plug is open.
4. Unscrew the filter element, do this procedure gradually. Auto repairmen recommend unscrewing the filter to half, then carefully drain the oil, after such manipulations it is permissible to remove the filter element completely.
5. Apply a few drops of engine fluid, similar to the one inside the engine, to the gum to seal.
6. Install the new filter device in place.
7. Check the engine fluid level, if necessary, add lubricant to the desired rate.

When changing the oil filter as described above, you can lose a glass of lubricant. Very careful motorists recommend pouring the engine mixture drained from the filter element back into the engine. We strongly do not recommend pouring drained fluid into an auto engine - this savings can be disastrous. Because when draining the specified liquid from the oil filter, it will not be possible to prevent dust particles and other contaminants from entering it. Plus, saving too much money on topping up will not work.

Conclusion

From a technical point of view, changing the oil filter and engine oil should be done at the same time. The operating period of the car oil and the filter device is approximately the same. By setting new element filtration without changing the lubricant, you accelerate the process of clogging of the filter device, because the aging process has already begun in the car oil. Changing the lubricant without changing the oil filter will not bring any positive results at all.

• after a major overhaul of the engine;
• if the car is brand new.

In these situations, grinding of engine parts occurs; frequent change of the filter device will not be superfluous.

During the operation of the car, intensive work of the engine occurs internal combustion. The lubrication system protects the internal motor units and assemblies from mechanical friction, rust. Lubrication removes from working under high temperature parts heat by circulating through the operation of the oil pump. Over time, engine oil becomes contaminated: various suspensions appear there, consisting of particles of metal chips, carbon deposits, and dust. There are recommendations on the timing of its renewal. In this case, it is recommended to carry out a complex replacement of all Supplies lubrication systems every 6-10 thousand kilometers. In practice, there are often situations associated with the lack of a suitable cleaning accessory at the time of the change, its breakdown, and leakage. In addition, in the case of new vehicles or overhauls"engine", it is recommended to renew the lubricant twice as often. In practice, many are limited only to changing the filter element of the car.

Is it possible to change the filter without draining the oil?

This question is often alarming, confuses many motorists, because they are afraid of spilling all the oil on the ground through the mounting hole on the engine block.

On this score, there is data obtained from the experience of many drivers. First, theoretically, when the engine is not running, the oil drains into the crankcase, which is below the level of the filter. Secondly, oil is pumped there only when the oil pump is running. Based on all this, it is logical to assume that the lubricant can splash out only in a small amount, which corresponds to the volume of the filter element itself.

Nevertheless, in order to avoid unpleasant situations, it is important to follow certain rules.

• Such manipulations must be carried out only on a cold engine. It is important that the car stood for at least an hour. Otherwise, hot oil may splatter from under the filter and scald your hands;
• In the area of ​​​​work, substitute a small container under the bottom to collect the flowing liquid;
• Unscrew the element slowly. First, half, expressing liquid lubricant, and only then completely remove it;
• The plug on the valve cover must not be unscrewed;
• On the new filter element, grease the sealing gum with oil;
• New filter screwed into place;
• After the procedure is completed, it is advisable to check the oil level with a dipstick, top up if necessary.

Changing the oil filter without changing the oil must be carried out in rare cases when it is impossible to do without it. It is best to replace consumables in a complex manner, while flushing the motor with special washes. Everything you need can be easily found in
