Malfunctions and repairs of the VAZ 2103 engine

Engine VAZ 2103 1.5 l. carburetor in-line 4-cylinder with overhead arrangement camshaft, the timing belt of the 2103 engine has a chain drive. The VAZ 2103 engine block is tall, more on that below. The service life of the 2103 engine, with careful operation and timely maintenance, exceeds factory installed 125 thousand km and reaches 180-200 thousand km.
The main differences between the 2103 engine and the increased block height by 8.8 mm from 207.1 mm to 215.9 mm to allow the installation of a crankshaft with an increased piston stroke, due to which the engine volume increased to 1.5 liters.
As noted in previous articles, Lada engines have a problem with camshaft wear. Due to the fact that the chain drive does not have a tensioner, the chain needs to be tightened, the engine also needs constant (every 10 thousand km) adjustment of the valve clearances, this will be indicated by a loud knocking sound in the VAZ 2103 engine when the engine is idling, audible from a standstill driver with the hood closed. Many people have a question, why adjust the valves, the answer is simple - power will decrease, fuel consumption will increase, the valve will burn out and many other pleasures of life. Adjustment of the VAZ 2103 engine valves must be done either by a master or with his own hands. To other problems, toWeber and Ozone arburetors constantly require CO adjustment and cleaning. It often happens that the VAZ 2103 engine gets hot, look for the problem in the pump, 99% this is it. Often when the engine in a 2103 misfires, there can be a lot of reasons, most often a burnt-out valve; in any case, you need to measure the compression and show the car to a mechanic. Many VAZ 2103 engine malfunctions repeat the problems of the 2101, due to their close relationship. For a more complete picture and so as not to miss anything, read about.
However, pAccording to popular opinion, the 2103 engine is the most reliable and unpretentious among the classic line of engines, and given the prices for spare parts for the VAZ 2103 engine, you don’t have to wonder why the classics are still driving along our streets.

Tuning the VAZ 2103 engine

Boost engine 2103

There are a lot of methods for modifying the VAZ 2103 engine, like all classics, from boring to a compressor with turbines, but let’s start in order. How to boost a VAZ 2103 engine, the cheapestand simple tuning of the VAZ 2103 engine was and remains a cylinder bore of 3 mm for a 79 mm piston from a VAZ 21011 or from a VAZ 2106, the output is 1.6 liters. Sharpening further, at 82 mm, will not work due to the too thin walls of the block.
To further increase the volume, you need to increase the piston stroke to 84 mm. Increasing the volume in this way reduces the maximum operating speed, the lower engine does not best choice for racing, but still. To increase the power of the VAZ 2103 engine by piston stroke, install a VAZ 2130 crankshaft, and also use TRT pistons, the connecting rods are seated to 134 mm. The disadvantages of TPT pistons are their lower strength compared to standard ones, the thermal load on the ring and the likelihood of piston burnout.

Engine boring 2103

1.6 l. 79x80 ~75 hp
Maximum torque ~115Nm at 3000rpm
With this configuration we get exactly the 2106 motor.
- larger diameter piston, standard stroke
1.7 l. 79x84 ~ 80 hp
Torque engine, non-racing configuration.

How to boost a VAZ 2103 engine by refining the cylinder head

The three-wheel engine uses the VAZ 2101 cylinder head, the main disadvantage of which is that it was developed for small-volume units. Accordingly, the flow sections of the channels do not correspond to the increased volume; this must be corrected by boring and polishing the channels.
Polishing and boring the VAZ 2103 cylinder head channels and manifold will significantly reduce intake resistance, engine power increases by 10% throughout the entire range. How to polish and which shafts to select is described in the article “Tuning the VAZ 2101”, due to the identity of the engines, all this applies to the engine of the Lada troika. The modification of the 2103 engine does not end there; a correctly selected camshaft for the 2103, as well as a modified head, can produce more than 100 hp.

Camshaft on VAZ 2103

The rule for choosing a camshaft is simple: in a lower configuration, when the piston stroke is large and it is larger than the cylinder diameter, you need to take a lower shaft with a phase of up to 270, a larger valve lift. Such an engine will turn out to be quite high-torque, urban and will go anywhere better than standard, at that time high revs will disappear. Which camshaft to choose for the lower ends, Estonets 1, Nivovsky 213 or something similar in parameters will do. For the top configuration, we accordingly select a wide-phase top shaft with a large valve lift.The standard head without modifications will accept the Mastermotor 48 camshaft, OKB Engine 480 and the like. More wide-phase ones will require additional work. The disadvantages of shafts with a wide phase are traction at the bottom; the angrier the shaft, the worse the ride from below and more unevenly idling, but by losing the lows we gain high power at the top. It’s up to you to decide which direction to move and whether it’s worth moving at all; the basic and most popular principles of boosting the 2103 engine were presented to you as simply and easily as possible.

Classic compressor

Compressor for 2103 great option It’s inexpensive to inflate a Lada; in stores there are ready-made installation kits with a pressure of 0.5 and 0.7 bar from an auto-turbo. Installing a 0.5 bar compressor on a classic is quite simple and requires minimal modifications; paired with a modified cylinder head, the engine produces more than 125 hp. This method is opposed by the price of all activities.

Turbo classic

This is, without a doubt, the most expensive and unprofitable method of boosting a VAZ 2103 engine. Your first cost will be converting the engine to an injector. Then we purchase a turbo kit for the classic, prices start from $1.5 thousand. Most kits are built on the basis of the Garrett GT17 turbine, they come without modification of the piston, but blow up to 0.5 bar. In this case, a classic compressor is more rational. In the case of a total modification of the 2103 engine, with the replacement of the piston, installation of the correct turbo shaft (phase 270-280, maximum lift), this kit will produce up to 1.2 bar with a power of more than 140 hp. The cost of such alterations will be more expensive than the car itself, even without taking into account the chassis, gearbox, brake system and other things 😀

14.04.2017

For the rear-wheel drive sedan VAZ-2103 (LADA 1500) or simply “troika”, the domestic manufacturer initially provided a new engine 2103 with a displacement of 1.5 liters, built on the basis of 2101. This model also used proven engines from a “penny” to 1 .2 liters and from VAZ-21011 by 1.3 liters. VAZ 2106 engines were produced in small quantities for the third Zhiguli model.

Engine VAZ 2103

Four-cylinder in-line carburetor power unit The 1.5-liter VAZ 2103 received an overhead camshaft, a timing chain drive and a high engine block, which allows the installation of a crankshaft with an extended piston stroke.

Zhiguli engines often suffer from camshaft wear or the lack of a tensioner in the drive chain, which needs to be tightened every 10 thousand kilometers. If a loud knocking noise occurs in the engine, you will have to adjust the valve clearances to avoid a loss of power, increased consumption fuel, valve burnout and other things.

Also among the disadvantages of the engine for the “troika” is the need for constant adjustment and cleaning of CO. If the engine overheats, pay attention to the pump.

If tripping occurs, you need to change the compression.

Engine tuning is possible in wide range: from boring to compressor and turbines.

Among motorists, the VAZ-2103 engine is in good standing, compared to other units in the line. The long service life is due to the availability of spare parts and their low cost. With careful treatment of the engine and timely maintenance, the VAZ-2103 will travel not 125 thousand kilometers declared by the manufacturer, but all 180-200 thousand kilometers.

Engine VAZ 2106

The 1.6-liter VAZ 2106 engine became a continuation of the VAZ 2103 and, as a consequence, 2101. The main differences from its counterparts are in the piston with a diameter increased to 79 mm, while the engine block remained unchanged.

There is also an injection unit 21067, which differs in its covered cylinder head from the Niva-21214 injection engine. Practice has shown that the “six” carburetor is more stable than the injector.

In general, the VAZ 2106 in-line engine has 4 cylinders, an overhead camshaft and a chain drive. Despite the possible service life of up to 180-200 thousand kilometers, among motorists the VAZ-2106 is considered less reliable than the “three ruble”. For the successful functioning of the “six” engine in winter time it has to be warmed up for at least five minutes at 1500-2000 rpm.

The disadvantages of the VAZ-2106 include increased requirements for oil, which can affect the increase in cylinder diameter. It often happens that oil consumption is a liter or more per thousand kilometers, which requires replacing rings, valves, or other things.

Also among the disadvantages of the “six” are increased wear of the camshaft, engine detonation, engine knocking due to defects in the piston pins or connecting rod bearings. At unstable work carburetor engine pay attention to the jets. An engine that stalls at idle requires adjusting the air damper.

When the engine heats up or boils, you need to check the thermostat, radiator and the presence of air in the cooler.

Trouble in the 2106 engine is caused by incorrectly adjusted valves, valve burnout, worn-out cylinder head gasket and low-octane gasoline.

Engine vibration is affected by worn-out cushions 2106, as well as an imbalance of the crankshaft and cardan.

You can add power to the VAZ-2106 by boring the engine by 33 mm under the piston by 82 mm; you cannot bore any more, since the walls of the block become thinner.

Engine VAZ 21011

The 1.3-liter VAZ 21011 power unit is an improved version of the “penny” engine. The main difference is the increase in piston diameter to 79 mm, which made it possible to add volume and successfully combine a short piston stroke and a good cylinder diameter, guaranteeing the unit high speeds, modest fuel consumption and confidence on the road.

All the disadvantages of the 21011 are identical to the disadvantages of the 2101 engine.

Engine VAZ 2101

The 1.2-liter VAZ 2101 power unit became the basis for the entire VAZ family. Unlike their prototype - the FIAT 124 engine, domestic engineers increased the center-to-center distance, which later allowed them to “play” with the engine displacement, which varied from 1.2 liters to 1.8 liters.

VAZ 2101 is an in-line carburetor unit with 4 cylinders, an overhead camshaft and a timing chain drive. Engines 1970-74 the releases turned out to be more reliable, since their production was controlled by FIAT specialists.

The disadvantages of the VAZ-2101 include increased wear of the camshaft and the need to constantly adjust valve clearances. Oil consumption on a “penny” reaches 0.7 liters per 1000 km.

Due to defects in the thermostat, the engine often overheats. Overheating of the 2101 motor is also indicated by fan failure, pump failure, or low-quality fuel.

The smokiness of the VAZ 2101 is caused by burnout piston rings, wear of valve seals, reworking of guide bushings, etc., which will force you to hand over the car for engine overhaul. As experienced owners of cars with a VAZ 2101 engine note, the shortcomings of the unit can be listed and repaired endlessly.

The Chinese auto brand Geely, together with the Swedish company Volvo, intend to begin production of the fifth in the Lynk & Co. crossover line. Information about this was published on the official portal of the Chinese Ministry of Industry.

The new product with the index “06” has already been repeatedly discussed in the media. It was expected that it would be a large crossover with three rows of seats. As a result, it turns out that the sixth model in the line will become very compact

Most likely, the new product will be assembled on the CMA platform. The overall dimensions of the new crossover are:

• length - 4.34 meters;
• width - 1.82 meters;
• height - 1.63 meters;
• wheelbase - 2.64 meters.

In terms of power, the new car will be equipped with a one and a half liter turbo engine producing 177 hp. A possible transmission could be a seven-speed robotic gearbox.

As for the design of the new product, the corporate style is easily guessed model line. The only differences that can be noted are the rear lights and a special “floating” roof.

In China, the new Lynk & Co 06 will be available in 2020. There is no information about the estimated cost yet.

Former presenter automotive program Top Gear Jeremy Clarkson has named the best and worst cars of 2019.

Popular automotive expert Jeremy Clarkson gave examples of the most successful and unsuccessful automotive projects of the current year. At the same time, the choice was not made on any specific type of car; Jeremy chose supercars, off-road cars, hot hatches, etc.

Mr. Clarkson is a sought-after and avid car enthusiast. He is known throughout the world as the host of the popular program Top Gear, to which he brought special sophistication. At least for this reason, his opinion should be trusted.

By analogy with previous modifications of the line ICE engine VAZ 2103 retained the overhead camshaft arrangement. The engine power has been increased, the attachment is rotated by a belt, the chain remains only on the timing sprocket.

Technical characteristics of the engine 2103

In the third ICE 2103, the manufacturer AvtoVAZ returned the original cylinder diameter of 76 mm and increased the volume of the combustion chamber, therefore technical specifications motors look like:

Design features

The engine diagram has the following nuances:

• camshaft from 2101 – one journal between the cams of the second cylinder is unprocessed (hexagon);
• cylinder head – inside the combustion chamber there is a 2 mm stage made by milling;
• drive - timing chain, pump and generator - 8 x 10 mm belt, 944 mm long;
• crankshaft from 2101 – 40 mm crank radius;
• The engine volume has been increased compared to the previous version 2101 - the block height is 8.8 mm larger, the piston stroke has increased.

For the domestic “classic” VAZ, there are general standards for what kind of oil to pour into the engine - 5W30/5W40 or 10W40/15W40. The cooling system here is combined (spraying and lubricant supply under pressure).

In this internal combustion engine, the intake manifold has a longer baffle to improve the stability of idle speeds, so the part is not suitable for earlier versions of engines. The exhaust manifold remained unchanged, allowing tuning through the use of a direct-flow muffler to increase the car's drive power.

Advantages and disadvantages

The main feature is the timing drive, so the 2103 engine must be serviced every 10,000 km. The camshaft wears out intensively, reducing engine performance. This version of the internal combustion engine manufactured by VAZ is characterized by all carburetor malfunctions.

But for these engines a major overhaul is provided, since they are serviceable; the manufacturer’s plant has repair kits for pistons and rings

What cars was it installed in?

The 2103 engine was created for the corresponding AvtoVAZ model, and later began to be installed on other cars of this manufacturer:

• VAZ 21023;
• VAZ 21043;
• VAZ 21053;
• VAZ 21061;
• VAZ 2107;
• VAZ 2121.

Due to technical features, the 2103 engine is always located longitudinally, so it is not used in front-wheel drive models.

Maintenance schedule

The official manual explains the design of the internal combustion engine and the timing of replacing consumables when servicing the engine:

Thanks to its simple design, oil changes and even major repairs can be done yourself. In Soviet times, car enthusiasts practiced engine modernization, the options for which are discussed below.

Malfunctions: signs, causes and solutions

The following breakdowns are typical for the 2103 engine manufactured by VAZ:

Attention: When the timing chain breaks, the engine bends the valve, so the tension and general condition of the links should be periodically checked.

Tuning options

The most popular tuning types are:

• boring the cylinder diameter by 3 mm to increase the volume (for serial piston 2101 or 2106);
• increasing the piston stroke to 84 mm and using a crankshaft from 2130;
• replacing connecting rods with parts 134 mm long.

Thus, the 2103 engine is qualitatively superior to the two previous modifications of the internal combustion engine of the AvtoVAZ manufacturer. The owner of a Zhiguli did not need to think about which oil to use, since the instruction manuals 2101 - 2103 are as similar as possible.

If you have any questions, leave them in the comments below the article. We or our visitors will be happy to answer them

If you are the proud owner of a family car VAZ model range called " Zhiguli"or popularly" Classic“and you still don’t know how to change the engine oil in your car’s engine with your own hands, then this article is for you. Although it is very strange that there are such people in the vastness of our homeland. After all, scientists have already proven that “our people”, knowledge and experience in repair Lada absorb with mother's milk and immediately after birth begin to harbor an inexplicable love for folk Classics- kopecks, sixes, sevens, etc. Joke:)

Now about the main thing - how to change oil And oil filter in a car engine VAZ-2101, VAZ-2102, VAZ-2105, VAZ-2106, VAZ-2107 and what you need to have for this.
First you need to buy an oil filter and four liters of engine oil. We choose the brand and type of motor oil according to the state of our wallet and the current time of year. As a medium-optimal option for Zhiguli cars, we can recommend all-season (10W40) semi-synthetic motor oil.
Tool needed for Changing the oil in the engine of a VAZ-2101, VAZ-2102, VAZ-2105, VAZ-2106, VAZ-210 7:
a) a hex wrench set to “12” and a metal tube with an internal diameter slightly larger than 12 mm,
b) a special key for unscrewing the oil filter (if it is not there, then there are two options left - your own hands and a screwdriver),
c) a 17mm spanner or socket wrench in your arsenal can also come in handy if suddenly there is a non-standard drain plug on the crankcase pan (see photo 1). You should also think about a container for draining old oil. The work of changing the engine oil should be carried out on an inspection pit, lift or overpass, since this procedure is quite inconvenient to carry out “from the ground”.. Let's save our nerves and strength!

1. Before engine oil change The car should be warmed up to operating temperature (70-80 degrees), then turned off and using a hex wrench set to “12”, unscrew the drain plug on the engine sump (photo 2) and, placing a previously prepared container, drain the oil. In order for the oil to drain better, unscrew the cap on the filler neck of the valve cover.

2. Using special unscrew the key oil filter(photo 3). If there is no key, then you can try to unscrew the filter with both hands; fortunately, getting to it is not difficult. If you cannot unscrew the filter by hand, a screwdriver will come to the rescue. This process has already been described in the article Changing engine oil on a Daewoo Sens car, if you wish, you can read it. But I hope it doesn’t come to that for you.
3. After the engine oil has completely drained, we screw the drain plug into the crankcase pan.
4. Before installing a new one oil filter, it should be filled with a small amount of oil and lubricated the rubber O-ring (photo 4). It won’t hurt if you wipe the oil filter seat on the engine block (photo 5).
5. Oil filter twist by hand! And after that, pour oil into the engine. Controlling the oil level using a dipstick. Its level should be between the MAX and MIN marks or not reach the MAX mark 2-3 mm.
6. Start the engine and let it run for a few minutes ( The engine oil pressure light should go out within 4-5 seconds). After this, turn off the engine and after 5 minutes check the engine oil level, oil filter and drain plug for oil leaks. If necessary, add oil to the engine or tighten the drain plug and oil filter.

Although the domestic classic represented by the VAZ-2106 is no longer produced, it continues to be actively present on Russian roads. The car was produced for 30 years at the facilities of the Volzhsky Automobile Plant. The first copy was released in 1976. This model can deservedly be considered a legend of the Soviet and Russian automobile industry. Not everyone knows that the prototype for creating a domestic car was the Italian Fiat car model 124 Speciale. Indeed, both cars are very similar to each other. It is not surprising, because the VAZ-2106 began to be produced just 3 years after the start of Fiat production. Since “sixes” are still relevant, the logical question remains about which oils are best to fill in VAZ-2106 carburetor engines.

When choosing engine oil for the VAZ-2106, there is no point in relying on the manufacturer’s recommendations.

Selection criteria

Every motorist tries to find the optimal balance between price and quality. After all, when buying frankly cheap lubricants, everyone understands what the operation of a car with such a lubricant can lead to. But not everyone is ready to spend money on too expensive compounds. To select the correct motor fluid, it is important to know the basic data of your VAZ-2106. This information includes:

• year of issue;
• motor type and its modification;
• level of wear of the power unit;
• climatic conditions of car operation.

But these data alone will not help give an accurate answer to the question of which oil will perform better in the VAZ-2106 engine. Experts recommend starting from two criteria:

• type of engine oil;
• degree of viscosity.

Let's look at these questions in more detail.

Engine oil type

All motor fluids on the market are divided into 3 categories:

• mineral;
• synthetic;
• semi-synthetic.

In the case of a modern foreign car, no one would doubt that only synthetics should be chosen. But in our situation, when we are talking about the VAZ-2106 car, things are different. Mineral oils have one important advantage. This is their low price. Although in terms of technical characteristics and properties they are significantly inferior to their analogues in the form of synthetics and semi-synthetics. It is not recommended to use mineral water if the climatic conditions are accompanied by severe frosts. At this temperature, mineral motor oil loses its fluidity, which causes problems with starting the engine. have a different composition, and their additives make it possible to more effectively protect the engine and prevent premature wear.

It is important to consider the year of manufacture your car. Old engines produced between the 70s and 80s are equipped with valve stem seals, oil seals and seals made of nitrile rubber. This material does not tolerate contact with synthetic and semi-synthetic oils. The rubber simply begins to break down. To eliminate this drawback, you should replace the seals with rubber products. Or fill the engine crankcase with mineral oils. Replacing seals with rubber ones is dangerous because on VAZ-2106 engines problems may arise with the power system. Gasoline will destroy rubber.

Viscosity

You should also select engine oil based on its viscosity. The level of fluidity affects the operation of the motor most directly. In the case of the VAZ-2106, it is better to fill it with summer and winter lubricants 2 times a year. This is especially important for regions with harsh winters, when the temperature on thermometers drops below -25 degrees Celsius. If the climate is moderate, then all-season oils are suitable.

The following motor oil viscosity parameters are most often used for the domestic “six”:

• 5W30;
• 10W30;
• 15W30;
• 20W40;
• 10W40;
• 15W40.

If winter is accompanied by severe frosts, it is better to focus on motor fluids with viscosity values ​​of 0W.

Manufacturers and brands

Everyone understands perfectly well that the VAZ-2106 belongs to the category of cheap cars that are available only on the secondary market. They cost extremely little, because the main target audience has a low level of financial wealth. It follows from this that they will not buy expensive motor oils. And there is no point in this, since the VAZ-2106 feels great when working on budget fluids. The ideal solution would be to purchase European motor oils. Although their high price does not always allow buyers to purchase similar products for their “six”. Car owners pay the main attention to domestic brands. The most popular include:

• Yukos Tourism;
• Azmol Super;
• Lada Standard.

Imported liquids have significantly higher technical parameters. This is where the main problem of choice arises. To guarantee confident, reliable and durable operation of the engine, it is better to spend a little more money but purchase high-quality imported oil for the VAZ-2106. If your financial condition does not allow you to spend a lot of money on servicing the VAZ-2106, you can get by with the domestic option. They are inferior in quality, but drivers usually do not feel a significant difference.

It makes no sense to look into the official VAZ-2106 operating manual, since the oils recommended there have not been produced for a long time or have lost their relevance.

The list of the most suitable brands for the VAZ-2106 available today includes:

• Optimum produced by Rosneft;
• Standard, produced under the Lada brand;
• Standard from Lukoil;
• Lukoil Lux;
• Lukoil Super;

The choice is quite varied, although here you should focus on the year of manufacture of your VAZ-2106. This applies to winter, summer and all-season motor oils. There are several important recommendations regarding the year of manufacture of cars. By adhering to them, it will be easier for you to decide on the final choice of lubricant for the engine.

1. VAZ-2106 cars produced between 1976 and 1982 should only be refueled. It is difficult to predict how they will behave on synthetics or semi-synthetics. It is better not to use them, otherwise it will result in serious consequences for the power unit.
2. If the "six" was produced from 1983 to 1991, then also use mineral-based oils or hydrocracking.
3. In the case of operating a VAZ-2106 car model 1992 - 1994, in addition to mineral compounds, it is allowed to pour semi-synthetic mixtures into the engine oil crankcase.
4. If you are lucky and you are dealing with a VAZ-2106, which was one of the last to be produced, that is, between 2004 and 2006, then feel free to buy high-quality semi-synthetic motor fluids. Mineral water is no longer suitable here, but there is no point in spending money on synthetics.

In terms of brands, everything is simple. Focus on the most popular manufacturers who have managed to gain a good reputation.

The most preferred brands for refueling engines of domestic automakers are:

• Rosneft;
• Lukoil;
• Shell;
• Mobil;
• Total;

Seasonality

It is important to decide which oils to pour into the VAZ-2106 engine, taking into account seasonality. In summer and winter, if the climate is moderate and the average temperature for the year is above zero, it is important and rational to pour all-season compounds into the oil sump. They usually have viscosities of 15W20, 15W40 and 10W40. But in winter, preference is given to viscosities 5W30, 5W20 and 10W40. They are suitable for VAZ-2106 cars up to approximately 2002. But for versions 2003 - 2006, it is better to use special winter compounds, the viscosity of which is 0W40 or 0W30.

Nulevki did not exist during the development of the VAZ-2106. These are oils with increased fluidity, which are unsuitable for use on machines with excessively worn power units. The “sixes” have survived to this day, only the bulk of them are operated with engines that have serious wear and tear. This led to the formation of gaps that, in the event of frost, will not allow engine oil with the 0W index to work normally. So only in exceptional situations would it be wise to buy such mixtures.

Usually, when selecting consumables for a car, the owner only needs to look at the official instruction manual. But in the case of the VAZ-2106, the situation is somewhat different. The cars have not been produced for a long time, plus the manuals are seriously outdated. So going by what the factory recommends doesn’t make much sense. Based on the tips and characteristics given above. With their help, it will be easier for you to make a choice and fill the crankcase with the correct engine oil that corresponds to the current state of affairs. In addition, we will give some useful tips.

1. Manufacturer of motor oils. In the case of the VAZ-2106 car, the priority for most drivers will be domestically produced fluids. But many imported compounds are also suitable for the six. Here, focus not on the geographical location of the brand, but on its position in the market. Try to choose mixtures that have been on the market for a long time. This suggests that they produce high-quality compounds that meet the requirements and standards.
2. Terms of Use. In our conditions and taking into account the technical features of the VAZ-2106, it is not worth delaying too much with changing the engine fluid. Replacement is recommended every 5 - 7 thousand kilometers. The more problems your “six” has, the shorter the intervals will be.
3. Trying to save money. Everyone understands perfectly well that no one wants, and sometimes cannot, spend a lot of money on maintaining such a budget car. But excessive savings can result in serious problems. Do not fill with questionable motor mixtures, but use proven, well-proven oils. Among them there are options at an adequate price.
4. Sales consultants. No offense to some sellers who are really trying to help customers. But most of them pursue personal goals and profit. For them, it is preferable to sell stale goods than to give practical and useful advice. Therefore, it is better to understand the issue yourself.
5. Fakes. The big problem for domestic motorists is the presence of a huge number. In this regard, try to avoid dubious retail outlets, counters and spontaneous markets. Go to specialty stores. Even though the oil there will be a little more expensive, you will be able to get all the documents, look at the certificates of quality and conformity, make claims if you buy bad oil, etc.

Always try to remember what you pour into the engine crankcase and what oil you use for your VAZ-2106, which has a carburetor. This will allow you to purchase a similar liquid next time. The age of the car is the main problem when choosing motor fluid for the VAZ-2106. Therefore, try to take into account all the recommendations given, build on the current state of the car and do not skimp on consumables. Otherwise, you will soon have to send the car to a landfill.
