Types of motor oil
There are several different types of lubricants for car engines, which we will now briefly review to make it easier for you to make the right choice.
Mineral
Traditionally, such oils are made on a mineral basis, but they are not well suited for VAZ 2109 engines. The fact is that they do not meet the requirements for oil changes and do not meet the strict operational characteristics of power units.
Semi-synthetics
Semi-synthetics
Such oils for the VAZ 2109 are also made on a mineral basis, but some synthetic components are added to them to improve the characteristics of lubricants during cold engine starts. Semi-synthetic oils keep the internal surfaces of the engine clean and reliably protect it from wear.
Synthetics
Motor oils with high performance characteristics are created using synthetic base oils. They are suitable for filling into both gasoline and diesel power units. They guarantee reliable wear protection and well lubricate working mechanisms even during cold starts. Synthetic oils minimize friction that is harmful to the engine and keep it completely clean. They meet the highest quality standards according to the API system and meet the approvals of automobile companies.
All-season
All-season oil
All-season oil can be any of the above. It is designed for engine operation in temperate climates and is suitable for year-round use. In the winter months, such oils hardly thicken, and in the heat, under the influence of high ambient temperatures, the lubricant does not dilute very much. Similar oils for the VAZ 2109 include lubricants with the following SAE parameters: 5W-40, 10W-40, 15W-40.

Welcome! Motor oil - it is found in almost any car, because it lubricates system parts, thereby reducing friction and increasing engine life. But like any other substance, oil also requires periodic replacement, but unfortunately, not all people know how to change engine oil, and therefore, especially for such people, we wrote an interesting article in which everything is described in detail.
Note! To change the oil, you will need to stock up on: A basic set of wrenches, and you may also need a special wrench for unscrewing the oil filter, or instead of a special wrench you can use a thick screwdriver. Also, to change the oil, take with you a clean rag so you can wipe your hands from dirt and a funnel for more convenient pouring oil into the car engine! (You can see what a special wrench for unscrewing the oil filter looks like at the very bottom of the article, in the “For Beginners!” section)
When should you change the engine oil?
- If you follow the manufacturer’s advice, then the engine oil needs to be changed every “10,000-15,000 thousand km”, or after “1-2 years” from the moment the oil is filled into the engine. (Whichever comes first)
Note! The frequency of replacement is also affected by: The condition of the engine, the brand of oil that was poured into the system, as well as the quality of the gasoline you fill the car with! (You can find out more about the timing of oil changes from the article entitled: “Oil change frequency and its choice”)

Filter and plug location
Changing the oil in a VAZ 2109 engine is not the easiest process, but you can handle this task if necessary. If you buy a used car from someone else, you need to change the engine oil as soon as possible. In this case, it is recommended to flush the engine with a special liquid, since you do not know exactly what was filled in earlier.
It is also recommended to change the oil if you have not operated the VAZ 2109 for a long time. When the engine is not started for a long time, condensation accumulates in it and mixes with the lubricant, causing a deterioration in its properties and, as a result, increasing wear on all internal parts of the power unit.
To extend the service life of the oil poured into the engine, wean yourself from starting abruptly or accelerating hard. We strongly recommend that you fill in a certain type of oil for each season - winter or summer. Always refuel only with high-quality fuel at trusted gas stations. Dirty fuel does not burn completely, causing contamination of the lubricant.

When to change
According to the instructions for “eight” and “nine” cars, the oil should be changed at least every 10,000 km . However, there are a number of nuances when the mileage for replacement is reduced or the oil needs to be changed:
- When buying a car second-hand, you need to change the oil . As a rule, the previous owner of the car, trying to “save money,” does not resort to changing the oil. Therefore, changing the oil on a newly purchased car will protect your engine from unpleasant surprises.
- After the car has been idle for a long time . For example, after winter storage, it is better to change the lubricant to a new one, since when the engine is idle for a long time, condensation accumulates in it. Mixed with engine oil, this suspension will negatively affect engine parts, causing their premature wear.
- You should also take into account the operating conditions of the vehicle . An aggressive driving style, as well as driving in urban conditions, contributes to intensive wear of internal parts. As a result, particles of metal shavings get into the engine lubricant, thereby worsening the lubricating properties of the oil.

What is required for replacement?
Filter key
To change the oil in a VAZ 2109 you will need a filter, suitable oil, and, if necessary, flushing fluid. Also stock up on rags and prepare a set of keys.
The amount of oil in a VAZ 2109 engine reaches 3.5 liters, but in practice the engine usually holds only 3 liters. You can find out which oil to pour into the VAZ 2109 engine from the car’s operating manual, but we recommend using semi-synthetic or 10W-40 synthetic from Castrol, Shell or domestic brands that have a more affordable price.
So, how many liters of oil are in the VAZ 2109 engine and what oil to choose do you know, which means you can begin the process of replacing the lubricant.
Technological stages of replacement
To successfully change the oil in a VAZ 2109 engine, you need to stock up on consumables and tools. It is advisable to prepare in advance:
- filters (oil and air - it is better to change them in pairs);
- high-quality motor oil;
- a set of keys;
- a crab wrench for removing the filter or a thick screwdriver;
- container for collecting used lubricant;
- funnel for filling in new lubricant;
- rags.
5-liter plastic bottles in which water was previously stored are used for drainage. The funnel can be replaced by the cut off top of a plastic bottle. Care should be taken not to allow large amounts of old grease to get onto the open ground.
Old grease is drained
Before this stage, the engine warms up well (up to 80°C). The car is installed on an inspection pit, overpass, or lift. Craftsmen use several jacks to evenly lift the car. In such cases, the raised part of the vehicle must be securely fixed with stops.
The engine oil filler cap is unscrewed. This is recommended to speed up the process of draining the old fluid. The removed cover breaks the vacuum, the oil will flow freely.
Place a container under the drain hole. The plug is first torn off with a key set to “17”, then carefully unscrewed by hand. As soon as the first drops of old oil begin to ooze, the plug is unscrewed completely, pressing it against the thread. Then they sharply pull the hand with the stopper to the side to avoid getting the heated oil on exposed skin.
Changing the oil filter
After waiting for the old lubricant to completely flow out, screw the drain plug back in. After this, the oil filter is unscrewed. As a rule, this is done manually. In cases where the filter has become stuck, use a special removable key. Its absence is compensated by a thick screwdriver, which is used to pierce the filter and unscrew it with a lever movement.
The new filter is filled halfway with fresh lubricant. This will prevent the effect of oil starvation the next time you start the engine. The rubber sealing gasket is lubricated with a new substance.
After this, the filter is carefully, without fanatical effort, screwed onto the threaded rod. There is no need to use a key to secure the filter completely. You only need to press with your hands without unnecessary strain.
New engine lubricant is poured
A funnel is inserted into the open oil filler neck. The required amount of new lubricant is poured through it. This is done slowly so that the oil has time to pass through the neck of the funnel.
Wait 3–5 minutes, and then, using a dipstick, check the level of the freshly poured lubricant. It should rise above the minimum level. If there is not enough oil, then you need to add it a little.
The oil filler cap is screwed on. The engine starts. It is allowed to idle for several minutes. It is important to monitor the oil pressure warning light. It should go out after a certain time.
Stop the engine and check the oil level again. The best option is for the grease to cover the dipstick just above the middle, stopping between the minimum and maximum marks. There is no need to add oil to the maximum. Excessive pressure places unnecessary stress on engine sealing parts.
Drain the old grease
Old oil
To better drain the oil from the engine, warm up the engine first. Drive the car onto an overpass or inspection hole, or you can use a lift or raise it with a jack on level ground. Raise the front of the car by placing chocks under the wheels.
Place a container under the drain plug, tear it open with a key and carefully unscrew it by hand. Be careful not to get burned, as we pre-warmed the engine. When draining the oil, it is recommended to unscrew the oil filler cap, which will speed up the draining process (the vacuum will disappear in the upper part of the engine).
Changing the filter
After draining the oil from the VAZ 2109, you need to screw the bolt into the drain hole and unscrew the oil filter. If you don’t have a special wrench and you can’t unscrew the filter by hand, use a regular screwdriver: pierce the filter crosswise with it and use it as a lever to unscrew it. Next, lubricate the gasket and threads of the new filter with oil and carefully install it so as not to strip the threads. When tightening it, do not use a wrench, but do everything by hand. It is also recommended to fill the new filter with oil about halfway to prevent oil starvation in the first moments of engine operation after starting.
