An important factor in the durability of car engine components is timely and correct replacement oils. How difficult is it to change the oil in the engine without the involvement of car service employees? Almost any car owner can do it on their own.

A motorist who independently decides to change the oil in the engine must have a number of simple skills. The manufacturer's instructions and this article will help fill the gap in knowledge.

We buy consumables

Read the instructions carefully before starting work. stock up consumables and the required amount engine oil. If you do not know your vehicle, then the oil label recommended for this car manufacturer, check the user manual.

You should not buy it at random points, as there is a high risk of buying a low-quality product. Pay attention to specialized car dealerships, where they can document the quality of their goods. In addition to oil, you will also need oil filter.

Where to begin

Changing the oil will be problematic, without checking into a viewing hole, overpass or lift. It is necessary to stock up on a container suitable for collecting used oil.

You will also need to change the oil:

• oil filter wrench;
• cleaning materials;
• rubber gloves;
• lighting device (lantern, lamp-carrying);
• wrench for the drain nut.

On the oil pan we find a hole for draining the oil. A key is being prepared, according to the size of the nut that closes drainer. A pre-stocked container is installed under the hole.

Draining old oil from a car engine

Before starting work, you need to securely fix the car. The vehicle must be parked handbrake or in the parking lot (for cars with "automatic"). The plane on which the car is installed must be flat and solid, preventing the car from sliding to the side.

The car engine is turned off. It is worth waiting a while for the oil and engine parts to cool, this will help to avoid burns when changing it. Next, the protective panels are removed that block access to the oil pan. Everything necessary tools and a container for draining “working out” are placed in an accessible place.

Then the container is installed directly under the pallet. The wrench (counterclockwise) loosens the nut that closes the drain hole. A loose nut is unscrewed by hand. It is worth checking that the o-ring located on the nut does not fall into the oil container.

After completely unscrewing the nut, remove it with a quick movement of the hand. We make sure that the oil flows into the container in order to avoid excessive pollution of our workplace. It is good to use fabric or paper as a bedding under the container.

After completely draining the oil, tighten the drain plug again.

Oil filter replacement

Find the location of the oil filter. We wipe its body with cleaning material. We loosen the filter manually (if possible) or with a key by turning it a couple of centimeters. We wait until the oil stops flowing. We install the drain plug exactly along the thread (to avoid damage if the plug is crooked), then tighten it tightly.

We unscrew the filter with a key, then, as it loosens, remove it by hand. We wipe the smudges with a cleaning material. We take new filter. Having previously checked it for defects in the place of the seat. We make sure that the sealing ring from the old filter does not remain in the seat.

Before installing a new filter, be sure to fill it with fresh oil. The oil pump needs some time to pump fresh engine oil through the system. By pouring oil into the filter, you partially do this work for him and reduce with insufficient lubrication. The new filter is carefully installed on seat. Tighten the filter with a hand and then with a wrench. We remove smudges with rags.

Pouring engine oil into the engine

We are looking for a filler neck on the engine. Unscrew the cap and pour engine oil with a funnel. The required amount of oil is indicated in the instruction manual for each specific brand of car. Let the oil sit for a while.

Video - oil change in BMW engine N52/N54/N55:

We collect all items under the car. We start the engine at low speeds. Using a flashlight or portable lamp, check the engine for oil leaks. After that, the car is carefully removed from the overpass or viewing hole.

You should not check the oil level if the car is at an angle, which is often the case on overpasses. To correctly display the oil level on the dipstick, you must install the car on a strictly horizontal surface. If the oil level is low, add it to the required mark. That's actually the whole procedure for changing the oil in a car engine.

If the car is a problem Motorbor

If the car the engine has broken down and needs it complete replacement? This is a whole problem but not the way you think. We recommend buying an engine with attachments in one of the best online stores of contract engines \"Motorbor\" Well, so that there would be fewer such troubles, we will tell in our article how to properly change the oil in the engine.

How to change engine oil

The process of changing the oil in the engine is simple. If there is no desire to turn to professionals on such a trifle, you can try to do it yourself.

First you need to buy suitable oil. It is better to buy oil in a company store, where the quality will be guaranteed and, if necessary, the seller will be able to give advice. It is advisable to purchase high-quality oil from well-known brands.

Changing the oil on your own is carried out as follows:

Before starting, you will need to drive the car into a pit or put it on a flyover.

Prepare inventory in advance: a bucket for draining old oil, wrenches, rags, gloves.

To increase the fluidity of the oil, it is necessary to warm up the engine. After warming up, wait a few minutes, otherwise you may get burned when draining the oil. Having climbed into the pit, we examine the bottom of the car. It may be necessary to remove the engine guard. Then we find the necessary cover on the engine crankcase and carefully unscrew it first with a key, then with our hands, we keep the bucket at the ready.

Some brands of cars drain at an angle so that the oil flow can get on your clothes.Draining occurs quickly, about five minutes, after which a little old oil remains in the engine, this is acceptable.

Oil filter replacement

At the same time as changing the oil, it is necessary to change the oil filter. If the filter is not changed, then clogged, it will stop working, and the oil will pass through the bypass valve without cleaning, which will lead to additional engine wear.

At various models car filters are located in different places. It is advisable to study the manual for your car in advance. Usually, manual effort is sufficient to remove the oil filter, but a special wrench may be required.

The filter cover is twisted, the old filter is removed. The installed filter must be impregnated, for this you need to fill it halfway with oil, also do not forget to lubricate the rubber band on the filter housing with oil.

Install the filter and screw the cap on tightly.

Filling in new oil

Screw on the crankcase cover. You can start filling oil. When filling, keep an eye on the oil level in the crankcase. The oil level on the dipstick must be between the upper and lower marks.

In total, about 80% of the oil in the canister is used for filling, the rest is left in case you need to add oil during the operation of the car.

Start the engine, warm it up, check for oil leaks, then reinstall the engine guard if it was removed.

What is the engine oil change interval

Modern synthetic oils can retain their properties for a very long time. It is usually recommended to change the oil at intervals of 10-15 thousand kilometers.

However, replacement intervals are reduced by 25-30% under the influence of adverse factors, such as: engine operation with overloads, strong and repeated temperature changes, increased dustiness or air humidity.

The power unit is a key element in the design of any self-propelled vehicle. The durability and reliability of its operation largely depends on how correctly and timely the oil is changed in the car engine. The role of lubrication in ensuring normal operation power unit hard to overestimate.

Thanks to engine oil, effective lubrication of the rubbing surfaces of the moving elements of the motor is ensured, the combustion chamber is constantly cleaned of soot and deposits, and excess heat is removed and dissipated from the engine housing and parts of the cylinder-piston group. Anti-corrosion additives, present in almost all types of motor oils, help protect the internal components of the power unit from rust.

Types and classification of motor oils

In the vast majority of engines internal combustion both diesel and gasoline, motor oils are used, which are classified:

• according to the chemical composition of the base: mineral, semi-synthetic, synthetic;
• viscosity (viscosity class according to SAE);
• quality (ACEA or API);
• tolerances or quality standards of car manufacturers.

Modern passenger cars are equipped, as a rule, with forced engines, for the lubrication of which synthetic motor oil is used. This type oils consists of fully synthetic components. Such synthesis products are characterized high stability physical and chemical properties; synthetic oils perfectly perform their functions under a wide variety of engine operating conditions. It is worth noting that it was the widespread use of "synthetics" that caused the world's leading automakers to increase service intervals between oil changes.

Engine oil change technology

Over time, any motor oil loses some of its properties. Under the influence of high temperature, aggressive products of fuel combustion, their molecular structure undergoes destructive changes - the old oil that has worked out its time must be replaced. This service operation is usually carried out in a specialized workshop, but can also be performed self-replacement oils. This operation does not cause any particular problems and is carried out using a standard set of tools: wrenches, a container for draining used oil, an oil filter puller. The procedure for changing the oil is as follows:

• the car is raised on a lift or placed on a viewing hole;
• the crankcase protection is removed (if any);
• the cap on the oil filler neck and the drain plug on the crankcase are unscrewed;
• after complete draining of the used oil, the oil filter is replaced.

The volume of oil poured into the engine must exactly match the data specified in the specification for a particular engine. Minor deviations from the norm will not lead to serious consequences, but significant overfilling or underfilling of engine oil can cause damage to the power unit. So, for example, an insufficient oil level often causes the engine to overheat, with all the ensuing consequences; strong overflow can lead to extrusion of the crankshaft oil seals.

Engine oil change methods

The classic way to change engine oil is to drain the used material through the drain hole in the crankcase. This procedure is recommended for stations Maintenance, where there is the necessary equipment (lifts, containers for collecting used oil, special tools) and qualified personnel. The oil filter must be replaced at every scheduled oil change. Often, the list of services provided additionally includes the replacement of fuel and air filter elements.

It is worth noting that in recent years, express oil change has become very popular. To completely remove exhausted engine oil, a portable vacuum unit is used, consisting of a compressor, a reservoir and a special hollow probe. Oil is pumped out through the hole for the oil dipstick. Obvious Benefits of this method are efficiency and low cost works, as well as the absence of the need to dismantle safety (engine crankcase protection) and decorative (plastic lining on the bottom and fenders) body elements. A professional express or vacuum oil change is carried out using modern equipment and is necessarily accompanied by an oil filter change.

The frequency of the "oil" service

The recommended oil change interval is listed in the vehicle owner's manual. The value of this most important service parameter depends on the type of engine, its specifications and operating conditions. Oil change intervals are determined by the vehicle manufacturer based on rigorous engineering calculations and extensive testing and testing. Therefore, during the planned after-sales service vehicle, it is recommended that you follow these instructions as closely as possible.

The interval after which the engine oil should be changed is indicated in kilometers or miles, but in parallel with these data, a time period can also be indicated - 3 months, 6 months or 1 year. It is worth noting that when deciding whether to change the oil, the mileage parameter is more significant than the time factor, especially if the car is operated in intensive mode.

The average mileage through which it is recommended to replace the old oil with a new one, for most cars is in the range from 8 to 12 thousand kilometers. The drain intervals given are average, but they may be adjusted depending on the operating conditions. vehicle. It is important to remember that engine oil change intervals should be halved if the following factors occur:

• use of fuel of unsatisfactory quality;
• operation of the car in taxi mode;
• intensive operation of the car in urban traffic jams and congestion;
• frequent driving on dusty and polluted highways;
• operation in conditions of extreme temperatures;
• aggressive or sports mode ride.

Strict adherence to service intervals for changing engine oil is a key factor that ensures not only long and trouble-free operation of the engine, but also achieves significant fuel savings. Do not forget that it is advisable to use high-quality original engine oils recommended by the manufacturer for a particular car model for engine lubrication.

Oil contamination causes wear and reduces the life of the rubbing parts of the machine. The power and reliability of the engine depends on its composition. Therefore, it is so important to observe the replacement periods recommended in the operating instructions for cars, taking into account real conditions.

An oil change takes place in several stages:

• purchase of necessary materials quality oil, flushing and filter);
• washing step;
• waste oil drain;
• filter change and new oil filling.

It should be noted that changing the oil in diesel engine will occur more often than in gasoline or gas.

flushing

This procedure is needed to clean the oil channels, remove carbon deposits and carbon deposits, it provides a larger volume of waste oil drain.

There are two types of flushing - soft and fast.

The last type is poured into the oil just before changing it, the flush is left for 10 minutes and it cleans the engine. It is used regularly, from the first days of operation of the car.

Soft flushing is poured into the engine, and in order for it to take effect, you must drive at least 200 km. She gently and carefully handles the details of the car. This flushing is especially relevant for older brands of cars.

For vehicles running on gasoline, special flushing compounds can be used. But if the engine is new and high-quality engine oil was used, then there is no need to flush, the lubricants already contain detergent additives.

After flushing, the engine oil should be changed.

During operation, the engine collects various pollution from the roads or from low-quality fuel. They settle in the motor lubricant composition and oxidize it, so it must be changed regularly.

Engine oil change methods

Usually oil is changed in the traditional way - by draining. Recently, car services offer express replacement, by vacuum suction. As a rule, this method is cheaper, the process itself takes less time: you do not need to remove the protection from the motor, you do not need to lift the car on a lift.

Classic way

To drain, you will need tools: an oil filter wrench, a combination wrench, a funnel, a container, a canister, a flashlight, and a rag.

The engine oil will be changed by draining it through a special hole located on the oil pan. It is carried out in several steps.

1. The engine warms up to normal operating temperature, otherwise mechanical inclusions will remain at the bottom. Then the drain plug located on the oil pan is unscrewed, after substituting a container to collect the lubricant composition. Draining time can be shortened by removing the filler cap.
2. If flushing is used, it must be filled in after the oil has been completely removed. Start the motor on Idling, wait a bit, then drain.
   Using a special key, unscrew the oil filter device. And the drain plug is wrapped back into the pan, after wiping it with a clean rag.
3. It is advisable to replace the old gasket with a new one. Before installing a new filter, it must be filled with oil. You can only screw the filter into place with your hands to protect yourself from difficulties during its subsequent removal.
4. Fresh oil is being poured. The cover is removed from the engine, new lubricant is poured using a funnel. Level control is carried out using a probe, it must be between the MIN and MAX marks. After pouring, the cover is installed in place.
5. The oil filter is being changed.
6. Start the engine and carefully check for oil leaks. The oil indicator should be in the "normal" position.

Advantages:

• open access to the bottom of the machine, as well as to its chassis. You can at the same time perform diagnostics of the running gear of the car;
• complete drain of oil, no residue.

Flaws:

• long process compared to express replacement;
• splashing of oil when draining around the machine, which leads to pollution and the risk of dirt entering the engine.

Express - way

The equipment is divided into professional and for home use. Professional systems are equipped with electric compressors, they have capacities with a volume for several replacement cycles. They are distinguished by quick-detachable hoses with special nozzles for different engines.

To make an express replacement at home, you need stand-alone equipment. It is a small container filled with air, the volume of which is discharged using a hand pump. The tank is designed for one cycle, reuse occurs after the tank is completely empty.

With this method, the exhausted composition is pumped out through the hole where the oil level dipstick is inserted. The process is carried out in several stages.

1. The engine must be warmed up to operating temperature so that the lubricant can drain into the crankcase.
2. The probe is removed from the hole, then the tube of the pumping device is inserted. It is lowered until it comes into contact with the surface of the engine. In the tank of the apparatus, air is discharged using a hand pump or compressor. Due to the pressure difference, oil is drawn out.
3. After pumping out the lubricant, the tube is removed. Then the filter is changed. The presence of a nozzle on the tube is checked so that it does not get lost when draining inside the motor.
4. Fresh lubricant is poured in, the level is controlled by a dipstick, which is then installed in place.
5. Oil filter replacement.

Advantages:

• you can do without a special key for the drain plug;
• express - replacement takes less time than a regular drain;
• oil change in the engine takes place in the normal position of the machine, there is no need for a lift;
• the process is environmentally friendly, does not affect the environment.

Flaws:

• the unreliability of the tube, it can be broken off or the nozzle left inside;
• drained of waste lubricant less than the first method.

How to change the oil in the engine, each motorist chooses for himself. You can contact the service station or make it at home, knowing the necessary techniques and choosing the appropriate method. But it should be noted that the best option is the alternation of express - replacement with the classical method.

Find out the type and amount of engine oil required, as well as the grades recommended by the manufacturer. Such information can be found in the instruction manual or on the Internet, as well as clarified with a consultant in the store.

You'll also need a filter. It is changed along with the oil without fail. You can select the correct element by the part number or the make and year of the car.

2. Prepare tools and materials

Changing the oil does not require sophisticated equipment and fixtures. You can get by with just a couple of keys and containers for draining mining. However, it is good if auxiliary tools and materials are at hand. Here's what you'll need:

1. New .
2. Oil filter.
3. Spanners.
4. Key puller for the filter (or belt, rope, screwdriver),
5. Capacity for draining (basin, cropped canister or bottle).
6. Latex gloves.
7. Clean rag.
8. Funnel (or sheet of thick paper).

3. Find the right place

The easiest way to change the oil is on a flyover or in a viewing hole. A free overpass is easy to find on the highway, in garage cooperatives and in some parking lots. You can use the pit from one of your friends.

If it is not possible to use a flyover, then in extreme cases you can raise the car with a jack. In this case, proceed with extreme caution: Be sure to securely support yourself after you have raised the machine and secured the rear wheels with wheel chocks.

4. Warm up the engine

In order for the old oil to drain well from the sump, it must be hot. Therefore, always up to operating temperature. It is convenient to replace after a long trip: in this case, you do not have to specially warm up the engine.

5. Fill flush (optional)

Flushing is necessary only when switching from one type of oil to another and for cleaning of contaminants for preventive purposes. In other cases, you can do without them.

There are two types of flushes: the so-called five-minute flushes and flushing oils. The first are cleaning additives - they must be added to the old oil before changing and let the engine run for idling. The second must be filled in instead of oil and driven several kilometers.

Depending on the agent used, proceed according to the manufacturer's instructions, which are always on the packaging.

6. Drain old oil

Before climbing under the machine, make sure it is securely secured with parking brake and wheel chocks. Put on gloves. Remove the filler cap so that the oil drains smoothly and does not burn you.

If a crankcase protection is installed on the car, dismantle it to access drain plug. Tear off the cork, then substitute a container to drain the waste and carefully unscrew the cork by hand. Be careful: hot oil will pour out in a strong stream.

driveavto-spb.ru

Wait 5-10 minutes until the remnants of the used oil drain completely, and in the meantime take care of the filter yourself.

7. Replace filter

Wipe off dirt and dust from the filter and the engine block next to it so that they do not enter the lubrication system when replacing. Try unscrewing the old filter by hand. Be careful, it also has oil! If the filter does not lend itself, use a special puller key.

Instead, you can use improvised means. For example, make a loop out of a generator belt or a strong cord and, resting some rod on it, try to turn the filter. You can also just wind a couple of meters of any rope on the filter and pull it. Or, in extreme cases, pierce the filter housing with a screwdriver and wield it like a lever.

Take a new filter, lubricate the sealing gum with a drop of oil. If it is installed with the thread up, then it must be filled with fresh oil. Screw on the filter by hand and tighten about ¾ of a turn after touching the sealing gum of the seat.

Don't overdo the puff! In no case do not use the key: the next time it will be very difficult to remove the filter.

8. Fill in new oil

Screw the drain plug into the pan and tighten with a wrench. Unlike a filter, you need to tighten it with medium effort, but without fanaticism. Some manufacturers recommend that you also replace the copper washer on the plug, as it shrinks and can leak if you tighten it multiple times.

Automagazin.sk

Install a funnel in the filler neck. If there is no funnel, from the cover of a magazine, a piece of paper or a cut bottle. Pour in about 80% of the required amount of oil, and put the rest aside for now.

Start the engine and check that the oil pressure indicator is on dashboard went out. Let the car idle for a couple of minutes, while you yourself make sure that there are no leaks on the drain plug and filter.

picbon.com

Stop the engine and wait 5-7 minutes for the oil to completely drain into the sump. Check the level with the dipstick and top up to the mid mark. If it is not there, then to the middle between the Min and Max marks. Add oil little by little, wait a few minutes and only then check the level again. Install the filler cap in place.

Don't overdo the oil! If there is more than necessary, the system will be overpressurized, which can damage the seals.

9. Dispose of used oil

Old oil must not be poured into a street drain or. Pour it into an empty canister, which is left over from the new oil, and then take it to a waste oil collection point. You can also contact the nearest car service: they will either accept a working off, or tell you where to hand it over.

10. Schedule your next change

The frequency of oil change is set by the manufacturer - on average, it is every 10-15 thousand kilometers. With constant operation of the machine in the city, frequent transportation of goods and other difficult conditions, it is better to reduce the service interval to 7-10 thousand kilometers.

Remember to regularly check the oil level every couple of thousand kilometers and top up if necessary, as drops below the minimum level impair lubrication and can cause oil starvation, which results in increased engine wear.
