How to change the oil in a VAZ 2109 engine yourself?

The first generation Samara family of cars, such as the VAZ 2108 and VAZ 2109, are equipped with four-cylinder engines of three sizes. Standard engine sizes for VAZ 2108-2109 models are presented in the following options: 1100, 1300 and 1500 cm³. This difference is due to different diameters of the cylinders, intake and exhaust valves and other design features of the engine. Using this photo report as an example, we will demonstrate changing the oil on a VAZ 21083 engine with a displacement of 1.5 liters.

Getting ready for replacement

The manufacturer sets the service interval for the VAZ 2109 at 10 thousand kilometers. It is recommended to change the oil regularly, which will ensure the performance of the car engine.

What kind of oil to pour

VAZ cars are traditionally unpretentious in terms of the quality of technical fluids, which allows the use of inexpensive auto lubricants. The manufacturer recommends using a lubricant with a viscosity of 5W-30.

Engineers advise using viscous compounds, which can reliably protect the moving elements of the power unit while effectively cooling the engine.

We can recommend that you use inexpensive semi-synthetics, which provide high-quality engine lubrication and at the same time have an affordable price. Remember that when purchasing semi-synthetics, you must take into account the engine size of your car.

Engine oil volume

First of all, you need to determine how much oil you need to purchase for this job. The oil volume in the VAZ 2109 car engine is 3.3 liters. When carrying out service work, 3 liters of technical fluid are changed.

We recommend that you simultaneously purchase a liter in reserve, since mixing liquids is not recommended, which may adversely affect its performance.

Please note that the volume of oil in the engine depends on the specific modification of the power unit, so you need to clarify this data in the technical documentation for your car.

Where to pour oil

The procedure for changing the oil on a VAZ 2109 is not difficult. When you open the hood, you can see the fuel filler cap on the engine. Just remember that it is not recommended to open it when the engine is hot.

When to change?

The car manufacturer provides replacement regulations. According to the official document, the oil should be changed once or twice a year or every 10-15 thousand kilometers. From time to time the oil is checked, its condition and color. If it is unsatisfactory, it must also be replaced.

Additional signs that replacement is needed:

• Year of manufacture of the power unit;
• Vehicle mileage;
• Vehicle operation style;
• Seasons in which the vehicle is operated;
• Fuel quality;
• Engine loads (long idling, slipping and towing).

The color of the oil fluid is black, and the viscous and elastic parameters are lost? In such a situation, the liquid changes regardless of timing. This is done to maintain power and extend engine life.

Step-by-step instruction

Changing the oil in a VAZ 2109 engine is not difficult. Every car owner can handle this job. We offer you step-by-step instructions for performing this service work.

Carrying out service work does not depend on the specific engine size of the VAZ 2109 and the modification of the power unit.

1. First you need to warm up the engine, for which we let it run for about 5 minutes.
2. The car is driven into a garage pit or overpass. With a certain amount of skill, you can carry out all the work without a pit or overpass. In this case, you need to carefully crawl under the car and place a flat container under the crankcase for old lubricant.
3. We find the drain plug on the oil pan and use a 17 key to unscrew it. Dark waste fluid will begin to flow out of the crankcase. We wait until it flows out, this usually takes 20-30 minutes.
4. After this, we change the filter, which is unscrewed manually without using a tool. In rare cases, the threads of the filter may become rusty, making it impossible to unscrew it by hand. In this case, you can use a special wrench or simply pierce the filter housing with a screwdriver and act as a lever.
5. As soon as the old auto lubricant stops dripping from the drain plug, you need to screw in a new filter, then screw the plug into place and carefully clamp it with a wrench. When tightening the filter, you should pour a little oil into it and lubricate the rubber gasket, which will prevent it from burning to the threads and will ensure better sealing of the system.
6. We unscrew the filler plug located on the cylinder head. We recommend adding oil using a funnel to avoid spilling it on the engine. Subsequently, such spilled liquid will burn for a long time and cause an unpleasant odor.
7. After filling three liters, you should check the dipstick, which will allow you to determine how much oil you have poured into the engine. If necessary, add fluid so that the level is between maximum and minimum.
8. Close the filler plug and start the car. Let the engine run for a few minutes, then turn off the engine and check the lubrication level again.
9. Inspect the car for leaks and, if necessary, tighten the oil filter or drain plug in the crankcase.

This completes the oil change in the VAZ 2109 engine.

Oil selection

How to choose the right oil? Such liquids are divided into three main types:

• Mineral oil;
• Synthetics;
• Semi-synthetic.

Mineral motor oil is not suitable for VAZ 2109. Such a lubricant does not meet the requirements if the car is operated in difficult conditions.

Semi-synthetics are used for VAZ 2109 . The basis of the liquid is mineral oil with the addition of synthetic components. This allows it to reliably cope with the protection of the internal surfaces of the motor and reliably protect it from excessive wear.

Synthetics are created with high performance in mind. It protects the power unit from wear, efficiently lubricating the internal mechanisms even during a cold start. Synthetic components reduce friction on internal parts and keep them clean.

But there is another type of motor oil - all-season. This is an ideal option for the VAZ 2109. Suitable for the Russian climate. In the winter season, the liquid does not thicken, and in the heat it does not dilute much. The main viscosity parameters for the engine of this vehicle are: 5W-40, 10W-40, 15W-40.

Top brands

Having selected the necessary parameters, you can proceed to choosing a lubricant manufacturer. Today there is a wide range of motor oils on the market - both cheap and expensive. There are original oils and their analogues. For the VAZ-2109, an analogue will be sufficient, but with suitable parameters. In addition, it is advisable to choose among well-known brands - for example, Lukoil, Mobil 1, Castrol, Shell, Rosneft, Kixx, Elf and others.

The performance of the car depends on the condition of the engine. And the health of the power plant is largely determined by what type of lubricant is used and how often it is filled. Changing the VAZ 2109 oil is a mandatory procedure that is performed on a regular basis. If you do not fill in new fluid in time, the amount of soot and other deposits on the engine elements will gradually increase, as a result of which the latter will fail.

What kind of oil and how much to fill in the VAZ 21093 injector engine

In accordance with the repair and operation manual, the volume of oil poured into such an engine will be 3.5 liters . In practice, only 3.2-3.4 liters fit, since 200-250 ml of lubricant remains in the motor itself and is mixed with the new one.

The car manufacturer has established technological requirements for motor oil. It must meet or be higher than the API quality standard: SF, SG, SH, SJ. Also, do not forget about the need to select motor lubricant by viscosity level, depending on the temperature in your area.

• SAE 15W-40 from -15 to +45 °C;
• SAE 10W-30 from -20 to +30 °C;
• SAE 10W-40 from -20 to +35 °C;
• SAE 5W-30 from -25 to +20 °C;
• SAE 5W-40 from -25 to +35 °C.

General tips for changing oil

Before traveling long distances, it is necessary to check the level of motor lubrication in the engine. This procedure is carried out with a cold, idle engine, and it is necessary that the car is on a flat horizontal surface. The lubricant level on the dipstick should be between o and “MAX”.

The replacement is made with the engine warmed up to operating temperature, then, being careful (so as not to get burned), unscrew the oil drain plug in the engine sump.

When replacing the oil filter, its O-ring must be lubricated with fresh engine oil.

The new filter must be screwed in by hand until the seal touches the cylinder block ring, and then firmly tighten it ¾ of a turn.

To perform the oil change job you will need the following tools:

• wrench to “17”;
• oil filter puller;
• waste containers of at least 4 liters;
• cotton gloves;
• clean rags;
• new oil filter;
• fresh motor oil.

A few words about methods and means of flushing the engine

1. Flushing oil. When changing the oil, the old oil is drained, and flushing oil is poured into the engine, which you need to drive for several days (from 1 to 3). At the same time, it is forbidden to put any load on the engine; the operation of the car during washing should be gentle. The popularity of this option is low due to the duration of the procedure itself, as well as the need to visit the service station several times. In addition, not every motorist will be able to drive carefully at low speed for three days.

Flushing fluid. This option is more common, as it takes a minimum of time and effort and is performed in one step. Such a liquid, as already mentioned, contains aggressive substances that, in a short period of time, wash away dirt, carbon deposits and other waste products of the engine. Each “flushing” has its own principle, but it looks something like this: drain the oil, add flushing, then start the engine and let it run for 10-15 minutes

It is important to remember here that when washing, the oil filter must also be changed; washing with an old filter is unacceptable. For flushing, you need to buy two oil filters - one is installed during flushing and the second after it is done.

1. Early engine oil change. Another option for flushing the engine is to change the oil ahead of schedule; with this method of flushing the engine, surfaces are cleaned in a gentle manner, and the oil, although it acts as a flushing fluid, does not contribute to diluting the oil. This may be news to many, but motor oils also contain detergent additives that simply do their job more slowly than flushing fluids. When replacing early, for example, after 2 thousand. km. mileage, all dirt or sediment is washed off and comes out along with the old oil. When washing this way, the oil filter also needs to be changed. You can do several such early oil changes, for example, after 2 thousand, and then after 4 thousand, in this way you can achieve a better result.

1. Complete flushing of the engine in a disassembled state. This method of washing occurs in a completely manual mode, and the power unit itself is dismantled and disassembled almost down to the screw. The washing itself is carried out in various ways, depending on the degree of contamination and the condition of the engine. This can be either regular gasoline or kerosene, or a special cleaning chemical used to wash engines. This method, although it is a last resort, allows you to personally assess the condition of the engine and all its parts.
