What kind of oil to pour into a VAZ 2109 carburetor engine

VAZ 2109: which oil to choose for the car

Typically, automobile oil protects the internal components of the engine, which rub against each other during operation. By reducing the friction force, parts wear out less quickly. Of course, much depends on the type of composition, which can be characterized by different operational parameters and be suitable for certain load or temperature operating conditions of the main unit. Thus, a pressing question arises for owners of the VAZ 2109 - which oil to choose? Knowing what kind of oil to pour into a VAZ 2109, the motorist will significantly extend the life of the car’s engine.

Types of oils

All motor oils have different preparation methods, viscosity levels, energy-saving parameters and purposes. When purchasing oil, you need to take into account the recommendations of the manufacturer of a particular brand of vehicle. Which composition is more suitable for a hot summer?

Mineral oil

VAZ 2109 which oil is better

Mineral motor oils have the following significant advantages:

  • cheapness and availability;
  • good viscosity and temperature characteristics.

In addition to the above advantages, there are also important disadvantages, namely:

  • it has to be changed frequently;
  • critical parts are not sufficiently protected if experimental loads are involved.

Note! If the VAZ 2109 car is quite old and does not require frequent driving, this option is perfect for the summer.

Synthetic oil

VAZ 2109 which engine oil to choose

Since the VAZ 2109 engine is often subject to significant loads, a synthetic compound is more suitable to reduce engine wear. Advantages:

  • the degree of viscosity is much lower than that of mineral oils;
  • maximum temperature spread;
  • lasts longer and does not require frequent replacement.

Note. Perhaps the only drawback will be its considerable price, but it is fully compensated by the good performance of the engine, as well as excellent preservation.

Semi-synthetic oils and hydrocracking

VAZ 21093 what kind of oil to use

In the case of semi-synthetic oil, the base is synthetic combined with components of mineral origin. Due to this feature, the mineral composition indicators increase. As for the price category, the cost of such oil is much lower than the cost of classic synthetics. As for hydrocracking, this motor oil is a worthy alternative to simple mineral water.
Its cost is approximately the same, while the characteristics of the composition are much better. Despite this feature, you will have to change the oil frequently.

Where to choose

Even in the summer in the northern regions of the country, the air temperature is not always high, so synthetic oils with a viscosity of 5W-40/5W-30 are recommended to be poured into VAZ 2109 cars that do not have engine oil pre-heaters.

Note! If the engine is physically outdated or the car has existed since the times of the USSR, it is not recommended to fill it with pure synthetic oil.

This feature can be explained by the fact that all the slag accumulated in the motor over the entire period of use will dissolve, which will lead to fogging of the motor. In addition, all deposits accumulated on the channels of the lubrication system will be washed away. As a result, oil starvation may occur.

Note! It is not advisable to pour synthetic oil of the 5W-40 or 5W-30 type into a VAZ 2109 with a worn out engine, since the gaps in the cylinder-piston group are relatively large. There may be excessive oil consumption due to waste. In other words, the composition will be discharged from the exhaust pipe.

Oil for new cars

VAZ 21093 engine oil

5W-40 or 5W-30 is a good synthetic oil characterized by excellent viscosity parameters. Such oils ideally resist oxidation; they can be used in engines operating under heavy loads or during hot periods of the year. Based on this, there is no need to change the oil frequently. If there is a need to reduce the load on a brand new Nine engine, it is better to purchase synthetic oil of the 5W-40/5W-30 type, which has:

  • reduced fluid friction;
  • a high viscosity index, due to which the load is removed from the battery and starter (see Do-it-yourself VAZ 2109 starter repair - an opportunity to save a lot of money) when the engine is turned on.

Which oil will be better

  • Amsoil professional oil is an excellent option for synthetic engine oil that can cope with various tasks even in situations where it has been used for a relatively long time. It is worth noting the 0W-30 oil series, ideal for hot summers.
  • Castrol Edge with Syntec Technology is more suitable for new cars. This oil is suitable for those car owners whose cars mileage exceeds the average. This composition does not need to be changed frequently and provides adequate protection against wear of parts. The organic combination of the additive with a standard synthetic composition is also appreciated. This combination makes it possible to reduce friction, save fuel and improve engine performance.
  • Mobil 1 oil is perhaps the most famous oil used by the large automobile concerns Porsche and Mercedes. The reason for this popularity is the highest performance and prolongation of the life of the car engine. Despite the existing advantages, not all car owners will be able to afford such luxury.

Note! You need to choose motor oil for VAZ 2109 cars based on the manufacturer’s recommendations or the advice of a specialist. The main thing is to ensure normal operation of the engine and protect parts from rapid wear.

Changing engine oil is easier than choosing it; if the procedure is being performed for the first time, you just need to watch the video and photo once, and you don’t have to go to a service station, you can actually do everything yourself without anyone’s help. It will also be useful to provide instructions and advice on selecting engine oil. Since this is a mandatory and important composition for the normal functioning of the engine and the entire vehicle system, it is recommended to buy good quality oil, the price of which cannot be underestimated.

What kind of oil should I use and how much?

VAZ 2109 owners often pour synthetic motor oils with a viscosity of 5W-40, 10W-40 and 5W-30. One of the most popular viscosity grades for this model is 10W-40.

The manufacturer has established a maintenance schedule every 15,000 km. In practice, owners try to replace them at 8-10 thousand.

When purchasing, you need to count on a 4-liter canister because... When filling, the engine immediately consumes 3.2-3.5 liters. Do not forget to leave 0.5 liters for daily monitoring and, if necessary, topping up the level.

In more detail, the table will help you navigate in choosing the viscosity and brand of oil, focusing on the geographic region of residence and the year of manufacture of the car.

Reasons for replacement

There are conditions that must be adhered to so that the lubricant present in the engine system fulfills its protective functions and turns into the cause of failure of the power unit.

There are several main points when an oil change should be carried out.

Recommended mileage exceededEach part has its own service life, during which the spare part uses up its existing resource. There is no point in continuing to use oil that should have been drained long ago. Otherwise, it may cause serious problems with the engine.
Change of seasonsFor winter and summer, it is recommended to fill in the appropriate type of lubricant. This is due to the degree of viscosity, outside temperature, characteristics of the intensity and cooling of the engine in winter and summer.
Changing the brand of lubricantIf you want to switch to a new brand of lubricant, the old oil must be completely removed from the system. Under no circumstances should you mix different oils, even by brand.
Difficult conditionsIf the car is regularly operated under high load conditions, oil changes are carried out more often than recommended intervals.

Regardless of the recommended replacement intervals, always pay attention to the current condition of the engine lubrication. Various factors can cause the oil to wear out prematurely, so it will have to be replaced earlier. Plus, additionally eliminate the reasons why the lubricant did not serve its intended purpose.

For summer, a more viscous lubricant is used than for winter. During prolonged operation in the engine, it loses its properties, additives, and chips from the engine's rubbing parts begin to adversely affect its condition. Over time, if the lubricant is not changed, this may lead to the need for a major overhaul of the power unit.

How to choose a lubricant for VAZ 2109

Once the type of lubricant has been selected, it is necessary to determine the viscosity of the oil, the value of which can be understood from the alphanumeric code on the packaging. For example, 10W-40. The first number shows the viscosity of the material at negative temperatures. The smaller it is, the lower the viscosity, which means that in cold weather the engine will start easier. The second number shows the viscosity at high temperature. The higher the number, the greater the viscosity as the engine load increases. If the oil is too liquid, it will not be able to form a protective film on the surfaces of engine parts, which will lead to rapid wear.

A little about oil

Before you begin the replacement procedure, you need to find out what and in what quantity should be filled.

VAZ 2109 cars are usually filled with 3 to 3.5 liters of oil. At the same time, it is recommended to purchase a 4-liter container, so that as you use it you have the opportunity to top up the lubricant used.

What oil?

The question arises: What kind of oil to pour? You shouldn’t go through a large number of brands; our Lukoil is perfect for the nine (just don’t run into a fake), synthetic or semi-synthetic, the quality is not bad, the price is lower in comparison with foreign oils.

Periodically check with a dipstick what level the lubricant is. It is optimal for a trace of oil to remain on the dipstick between the maximum and minimum marks. Golden mean. It’s not worth filling above the maximum mark, just like driving with underfilled lubricant.

We have decided on the volume of oil. What exactly should it be?

If we take into account the issue of quality, the optimal solution for the VAZ 2109 would be a synthetic lubricant. But it is the most expensive. Semi-synthetics are more affordable, but the quality characteristics are lower. If finances do not allow it at all, you can get by with mineral oil. But it’s better not to skimp on this issue.

Another point is that if you have an engine with a fairly high mileage, then it is best to use semi-synthetic oil.

Do not mix different brands of oil under any circumstances, and when replacing, first flush the system with a flushing compound, and then fill in new fluid.

Filling with new engine oil

Filling with new engine oil

If the oil filler neck is closed, unscrew the cap by turning it counterclockwise about half a turn. Pour the required amount of oil into the VAZ 2109 engine. Do this slowly, as the oil is quite viscous and slowly flows down the walls.

Using a dipstick, check the oil level in the engine - it should not be below the minimum mark. If the level is lower, add a little oil. Start the engine and leave it running for a few minutes until the pressure warning light goes out. Check the lubricant level again - if it is normal, you can actively operate your VAZ 2109.







Now let's get down to work. There is nothing complicated here, so even a beginner can cope with the task.

  1. Prepare a container in advance where you will drain the used lubricant from the engine. A regular 5 liter plastic bottle will do just fine. Plus, you'll need a funnel so you don't miss it and spill oil on the floor.
  2. Warm up the engine. When the engine is hot, the oil becomes less viscous, which allows it to more efficiently and quickly exit the system when drained.
  3. Place the car on a flat surface and turn on the handbrake.
  4. Proceed to remove old grease. To do this, remove the engine protection, if any.
  5. Place a drain container under the crankcase pan and unscrew the drain plug with a 17 mm wrench.
  6. Don't forget, the oil is hot, so unscrew it carefully to avoid burns.
  7. After removing the drain plug, wait about 10-15 minutes until all the oil is drained into the prepared container.
  8. In parallel with changing the engine oil, it is recommended to change the oil filter. This can be done while the grease is draining. The filter is unscrewed with a special key or screwdriver, breaking through the housing. A new oil purifier is installed in its place.
  9. When the lubricant has completely drained, return the plug to its place.
  10. Pour some oil into the new filter. This must be done in several approaches so that the element has time to absorb the substance. Filling to about half the filter level is enough.
  11. Be sure to oil the filter rubber seal and wipe the seat of the filter device dry with a dry rag. Place the filter in place and tighten it by hand.
  12. Next, you will need to either simply add fresh oil or flush the system. Nowadays you can find a variety of cleaning products in any auto parts store. Take one of them and follow the instructions. After completing the flushing, you can fill in new lubricant.
  13. To fill, open the lid on the motor and gradually begin pouring liquid through the funnel.
  14. Fill in about 3 liters and wait until the lubricant is distributed throughout the system.
  15. Gradually add another 500 milliliters of liquid. At the same time, monitor the amount of oil in the crankcase using a dipstick. If you have not flushed the system, you will probably have to fill in a little less than 3.5 liters. This is due to the imperfection of the drainage system.
  16. Make sure that the dipstick shows the mark between the maximum and minimum lubrication levels.
  17. Screw on the cap, start the engine and let it idle for a while. This will allow the liquid to fill the filter and channels.
  18. When you start the engine, the red oil pressure indicator light will come on. After 10 seconds it will go out. If the lamp does not go out, most likely you have not screwed the filter on properly. Check it out.
  19. Stop the engine, take the dipstick again and check the actual level of lubricant in the crankcase. If required, add a little liquid to the optimum level.
  20. When completing work, be sure to check the system for signs of oil leaks. If the protection has been removed, return it to its place.

Where to pour oil into the VAZ 2109 engine and how much it will be needed

Oil filler neck VAZ2109, 21099

The question of where to fill engine oil in a VAZ 2109 is obvious to every car owner who understands at least a little about the design of the engine. You just need to unscrew the oil filler cap (it is shown in the picture above), located on the top of the engine housing. It opens by turning ninety degrees counterclockwise. Oil is poured through the opened neck into the engine. A more complex question, which not everyone can answer, is what kind of oil to pour into the VAZ 2109 engine. And also how much of it will be needed. Our article will help you deal with all these difficulties in order.

What kind of oil to pour

Everyone knows that the heart of a car is its motor (engine) and that this unit requires special attention. Its service life largely depends on the quality of the oil used. Therefore, let's start with the most important question, what kind of oil to fill in the VAZ 2109 engine? Of course, every owner tries to use what is expensive. Although now, due to the large number of fakes, a high price does not always mean proper quality. The use of low-quality oils (and lubricants that do not meet technical specifications) leads to increased wear of engine parts and its premature failure.

How to determine what is suitable for you in a huge variety of brands and companies of motor oils, what you should pay attention to when choosing:

  • First, you should read the car manufacturer's recommendations. Carefully study the service book of the machine to understand what oil the manufacturer recommends for this engine and its viscosity
  • If your car already has good mileage, then you need to know the degree of wear of engine parts and what kind of oil was used
  • For example, if in a VAZ 2109 engine, where mineral oil is poured, for several years, microcracks in the engine gaskets are filled with deposits, they are not washed out during operation of the car
  • However, when replacing mineral with synthetic, with higher penetrating and cleaning characteristics, such deposits are washed out, and fluid oil comes out through these microcracks, and your engine suddenly begins to “sweat”
  • The golden mean between mineral and synthetic oil is semi-synthetic
  • Meanwhile, the concept of “semi-synthetics” does not exist anywhere except Russia
  • Often, this type of lubricant is obtained from mineral water by hydrocracking, which significantly improves its characteristics
  • The main advantage of semi-synthetics, first of all, is price.
  • In addition, for an engine that has worked for many years on mineral lubricant, switching to semi-synthetics will not be particularly critical (if, of course, the oil was of decent quality)
  • The next criterion for choosing a lubricant is its viscosity, which characterizes the ambient (air) temperature in winter when starting the engine and the temperature in summer at the highest load

How to choose the right lubricant with the desired viscosity value:

  • Today in the world there is a standard SAE classification based on viscosity level
  • The SAE marking contains the most complete and concise description of all oil properties
  • They are divided into winter classes (0W-20W), as well as summer classes (20-60)
  • The viscosity grade is indicated by a double number
  • In which the first digit means dynamic viscosity at sub-zero winter temperatures, at which easy engine starting is guaranteed
  • The second number means the kinematic and dynamic viscosity of the lubricant at 100°C and 150°C in summer
  • SAE classification informs the consumer of oils that have a maximum operating temperature at which the engine is cranked by the starter without problems, and the oil pump pumps lubricant during a cold start of the engine without friction to dry in its rubbing components
  • Lubricants with a viscosity of 50-60 are intended for powerful engines, as well as for engines that already have a decent mileage (over a thousand kilometers)
  • Synthetics in such engines will constantly leak through oil seals, gaskets and other seals due to their increased fluidity

What else does the owner of a VAZ 2109 need to know, what oil to fill, taking into account today’s specifics:

  • The engines that are currently installed on many VAZ models are very different from those that were installed previously
  • The main features are an injection fuel supply system and equipping the vehicles with an exhaust gas neutralization (afterburning) system, which complies with Euro2 requirements and standards.
  • Because of this, fundamentally new (increased) requirements for the properties of lubricants began to arise.
  • Therefore, in the late 90s, he made special amendments to his own system of standards and approvals for lubricants, which was developed back in the 70s
  • Taking into account the specifics of the VAZ vehicle fleet, the Scientific and Technical Institute has developed a two-stage system of motor oil standards
  • There are now two main classes - Super and Standard.
  • “Standard” is recommended for use in “classic” engines, which were produced no later than October 1, 2000
  • According to the API classification, “standard” oils belong to the SF class, which now corresponds mainly to mineral products, as an example - “TNK Motor” (SAE 10W-30 or 15W-40 and 20W-50)
  • For VAZ-2108.. -1111 models, and VAZ cars manufactured later than October 1, 2000, “Super” class oils corresponding to the properties of SG are recommended
  • “Super” class oils are also recommended for cars produced at Zaporozhye and Lutsk factories in the same period
  • For example: in the range of the most widely represented TNK oils, the “Super” class includes semi-synthetic “TNK Super” (corresponding to SAE 10W-40 and 5W-40) and mineral water “TNK Super” (corresponding to SAE 15W-40)
  • They are recommended for use in injection engines that are equipped with exhaust gas neutralization systems
  • In 2003, TNK Super oil underwent repeated technical tests, following which it was approved for use in the latest car models with a replacement interval of 15 thousand kilometers.
  • This means that the “service life” of “Super” products is significantly increased, so they provide reliable operation more than other lubricants with the usual 8-10 thousand mileage between shifts
  • However, it is necessary to take into account such factors as: the quality of the fuel used, engine operating mode, road pollution, as well as the ability of the machine’s filter elements to operate for more than 10 thousand kilometers
  • Now that it becomes clear for the VAZ 2109 - VAZ 21093 which oil to fill, we move on to the questions of when and how much.

When to fill

The replacement time is specific for each engine, type of lubricant and operating conditions, therefore it is different for each car manufacturer, plus the mileage before major engine overhaul is of great importance, so we take on average:

  • Under standard vehicle operating conditions, the lubricant should be changed every 10 thousand kilometers.
  • In Russia, it is better to reduce the interval between replacements to 7-8 thousand, since the operation of vehicles, according to the experience of many motorists, occurs in difficult conditions
  • Be sure to change the oil filter when changing the oil.

Determine the amount of lubricant required for filling

To determine the amount of oil in the engine, there is a special dipstick - a meter, which is located in the middle of the cylinder block on the right side, as shown in the photo.

The dipstick is a lubricant level meter in the engine (indicated by a red arrow)

To add (fill) lubricant into the motor you need to have on hand:

  • Fresh motor oil with a viscosity that meets the specifications for your engine
  • Filling funnel, instead of which a cut-off polyethylene bottle will do
  • Clean rags

Helpful Tips:

  • To reliably determine the amount of oil in the engine crankcase after a trip, you need to turn off the engine, let the oil drain into the pan, wait 5-10 minutes
  • If you add lubricant, use the same brand and company that was poured into the engine when changing
  • It is not permissible to exceed the level above the maximum mark on the dipstick to avoid leakage through seals and gaskets, and increased flow
  • Perform level measurements by placing the machine on a horizontal, level surface.

Execution order

In order not to make a mistake and not to overfill above the required level, and thereby not create unnecessary problems with the engine, you should check the lubricant level on the dipstick, as stated in the instructions and the tips given just above:

  • Remove the dipstick from the engine and wipe its surface with a clean rag, then insert it into place
  • Remove the dipstick again, the engine oil level should be between “MIN” and “MAX”
  • If the level is lower, then top up to the required level.

Markings of the minimum and maximum permissible level on the probe meter

  • Remove the cap from the oil filler neck
  • Insert a funnel into the neck and add oil, periodically checking its level with a dipstick.
  • To properly check the level, let it drain for 2-3 minutes after topping up.
  • If suddenly the level after topping up exceeds o, it is necessary to remove excess lubricant
  • This can be easily done using a medical syringe by putting a flexible tube on it, inserting the syringe tube into the probe hole, and pumping out the excess
  • In winter, you should not use a lubricant with a viscosity higher than necessary in the engine, otherwise in cold weather it will be difficult to start the engine

Now questions like how much oil to fill in the VAZ 21093 have disappeared by themselves, we top it up according to the level and when changing it we fill it according to the included operating instructions for the machine. In addition, you can easily pour the required amount into the motor with your own hands.

The last question that any car owner faces when changing lubricant is whether flushing is necessary. Flushing is required:

  • If you do not know what oil was used at the previous change or have forgotten
  • If you decide to change the brand
  • If the waste drained from the engine is heavily contaminated

In other cases, washing is a personal matter for each owner. It has its pros and cons. The advantages include:

  • Removing soot, carbon deposits and deposits from the lubrication system, as well as wear products from parts that are not washed out by oil
  • Cleaning the previous lubricant protects the new one from precipitation and loss of properties in case of incompatibility with the previous brand


  • Not all of the rinsing is washed out of the engine; its remnants dilute the new lubricant, which makes it lose a little in its properties.

Therefore, the best flush is a lubricant that you will use later, although it can be expensive to use as a flush. Engines with high mileage usually require flushing. That's all, the question on the VAZ 2109 where to fill the oil is closed once and for all, I hope. If you forgot something or didn’t quite understand, read from the beginning or watch the video.
