Changing the oil in a VAZ engine: what you need to know for self-service

Changing the oil on a VAZ 2104

So, it's time to change the oil in your "four". In what order is the oil changed in a VAZ 2104 engine? How to determine what kind of oil to pour into the engine? Do you need to change it right now? Should the engine be flushed with special products? You will learn the answers to the above questions from this article. There are also detailed instructions for changing the oil, choosing it and useful tips, which are highly recommended not to be forgotten, as well as useful practical photos.

Consequences of untimely replacement

What can result from an untimely oil change in the VAZ 2107 gearbox:

1. The box will be louder. Extraneous noise will appear, uncharacteristic of the gearbox. This may happen when the engine is cold, but as the engine warms up the sounds will disappear. Or the transmission may be noisy regardless of the temperature of the power unit.
2. When changing gears, a crunching sound or other extraneous sounds may occur. Failure to change the oil in a timely manner will result in it losing its properties and being unable to properly lubricate the internal parts of the gearbox. Replacing the substance often solves the problem of crunching.
3. Faulty gearbox bearings. If the lubrication is poor, bearing mechanisms will operate under high load conditions. This will cause the parts to wear out faster and soon fail. Wear products from bearings and other elements can clog the oil channels, which will affect the increase in pressure in the lines of the transmission system. As a result, the lubricant will begin to squeeze out the oil seals and seals. This problem can lead to a transmission fluid leak.
4. The appearance of vibrations during operation of the gearbox. Often the vibrations disappear as the engine warms up, but it is possible that they remain and do not disappear. It is not a fact that the problem is related specifically to the quality of the motor fluid. Perhaps this is a consequence of the use of used oil, which has lost its properties, which led to wear and failure of some structural elements of the unit.
5. One of the most serious consequences is gearbox failure. If the car is constantly used with used oil, this can lead to breakdown of the unit. The gearbox will need to be repaired.

Regarding the low prices of some brands, it is difficult to say which are better and which are worse. These data were obtained based on surveys among motorists.

Transmission oil

Finally, let's take a look at the transmission. In VAZ classic models, lubricant is poured into the gearbox and gearbox, and starting from the VAZ-2108 model and higher - only in the gearbox (they do not have a gearbox). Moreover, these units use a special oil - transmission oil. This lubricant does not require replacement as often as power plant lubricant, and the general requirements for it are much lower.

When choosing VAZ-2107 transmission oil for the winter, you don’t really need to take into account the nuances. Transmission elements use oils with SAE classification index 75W-85, 80W-90, etc. It is poured into both the gearbox and gearbox.

The same oil is used in more modern VAZ models. To more accurately select transmission oil for a particular car, it is better to find out in the operating instructions what kind of lubricant is needed.

A few final words

Briefly some tips:

• Choose quality oil! Beware of fakes.
• Monitor the condition of the engine. If oil is flowing, this is not a sign that it exists; it must be eliminated!
• Change the oil on time. Do not allow the engine to run on oil that has already lost its performance properties. This threatens intensive wear of the engine, including the crank mechanism, the repair of which is not so cheap!
• Don't overlook the condition of the filler plug!

The fill plug should be ok

• Watch the video on changing the oil to make it more clear what, how and why to do.

Take care of your car and it will serve you for a long time!

Leaks and problems

The higher the mileage of the VAZ 2104, the more problems appear, as in principle with any car. Most often this is due to natural wear and tear of the engine, causing oil to burn. Although the manufacturer allows for a small consumption.

There can be many reasons why an engine eats oil. And in each case they can be individual. But, over the years of the model’s existence, we can talk about the most common places where leaks occur.

If the breather is spewing or throwing oil, or if there is oil in the exhaust manifold, this may indicate a serious problem with the oil rings. In this case, you can try decoking with dimexide. But it is better to use special auto chemicals designed for these purposes.

A leak from under the valve cover may be due to a worn gasket. Sometimes simply replacing the gasket does not solve the problem. Since the cover itself may have significant curvature. Therefore, in some cases it will have to be replaced.

A white emulsion in the engine or on the oil filler cap may indicate condensation. This is a common occurrence when temperatures change from minus to plus, mainly in autumn or spring.

But if the emulsion is also observed on the dipstick, then this is already a sign of more serious problems. Most often we can talk about a broken cylinder block gasket. And in rare cases, a cracked cylinder head may be to blame.

Also, with this problem, you can find oil in the expansion tank. Sometimes, simply replacing the gasket is not enough. It may be necessary to grind the head itself, and this is completely different money for repairs.

All this is general information, which may manifest itself differently on each specific vehicle, since everyone’s operating modes are different. The same applies to places of leaks or oil leaks. Therefore, it is impossible to identify the cause from a distance.

Viscosity

Let's start with the fact that one of the main parameters of a lubricant intended for filling into power plants is its viscosity. This characteristic determines the fluidity of the oil under different operating conditions. It must be fluid while cold (to ensure ease of starting the engine) and maintain viscosity, that is, not drain from the surface, after heating. It is the viscosity of the oil that is one of the main criteria when choosing. To designate lubricants by viscosity, a whole classification has been introduced - SAE.

According to it, all oils are divided into:

• Summer;
• Winter;
• All-season;

The first two options are relatively rare in our country; they are more intended for use in conditions of year-round stable temperatures. For the summer version, the main criterion is the preservation of viscosity at high temperatures, and fluidity at low temperatures is practically not taken into account. And everything is exactly the opposite for the winter version.

Since we have large seasonal temperature changes, it is simply not practical to use summer and winter oils separately. Therefore, it is more rational to use all-season lubricants. Moreover, they also come in different viscosities, so you should also choose the right engine oil for the winter in your VAZ.

To indicate the viscosity of all-season motor oils according to the SAE classification, an index consisting of numbers and letters is used. Examples of such markings are 5W-40, 0W-30, 10W-50, etc. The first part of the marking indicates viscosity values ​​at low temperatures. Essentially, this indicator indicates at what minimum temperature threshold the lubricant will remain fluid enough for the oil pump to “push” it through the system. And in this case, the lower the number of the first part of the marking, the greater the frost the lubricant will withstand. Thus, oil with an index of 5W will remain fluid at temperatures down to -30 degrees, but for 15W the maximum temperature threshold is already -20 degrees C.

The second part of the marking indicates viscosity at high temperatures. Here the opposite is true: the higher the number, the higher the viscosity after heating.

To select the viscosity of engine oil for the winter for a VAZ-2114 or any other model, you just need to determine the temperature in different seasons. So, for northern latitudes, you should first of all be guided by low-temperature viscosity, that is, by the first part of the SAE index. If in winter the temperature drops to -30 degrees. C and below, it is better to use 0W or at least 5W oils. Using a lubricant with a higher index will lead to the fact that in severe frosts the oil will be so thick that the starter will not be able to crank the crankshaft. But for southern latitudes, you should focus more on the second part of the index, that is, high-temperature viscosity.

For latitudes with a temperate climate, winter oil for the VAZ-2106 (in general, it does not matter which model) you will have to find a compromise so that the lubricant remains liquid in winter and viscous in summer. The optimal oil for such a climate is 5W-40.
