An internal combustion engine is a unit that needs constant lubrication. This rule also applies to VAZ 2107 engines. If the car owner wants the car to serve him for many years, he will have to regularly change the oil in the engine. Is it possible to do this on your own without resorting to the services of qualified auto mechanics? Yes. Let's figure out how this is done.
Why you should change the oil in the VAZ 2107 engine
The VAZ 2107 engine is literally packed with various rubbing parts, the surfaces of which need constant lubrication. If the oil for some reason does not reach the rubbing parts, they will immediately begin to overheat and eventually break. And first of all, the valves and pistons of the VAZ 2107 suffer from the lack of oil.
It is extremely rare to restore these parts after malfunctions in the lubrication system. In the overwhelming majority of cases, the engine requires a very expensive overhaul. That is why the driver must regularly check the level and quality of the lubricant in the engine, and, if necessary, change it. In the operating instructions for the VAZ 2107, the manufacturer recommends changing the oil every 15 thousand kilometers. However, experienced owners of the "sevens" recommend changing the lubricant more often, every 8 thousand kilometers. Only in this case, the VAZ 2107 engine will work for a long time and stably.
How to drain oil from a VAZ 2107 engine
Before starting work, you need to select all the necessary tools and consumables. Here's what we need:
- set of socket wrenches;
- puller for the oil filter;
- a container into which the old oil will be drained;
- 5 liters of new engine oil;
- funnel.
Sequence of operations
First of all, an important point should be noted: all work on draining oil from the VAZ 2106 should be carried out on an overpass or on an inspection pit.
- The engine of a car parked in the inspection pit starts up and idles for 10 minutes. During this time, the oil in the engine will become as liquid as possible.
- The hood of the VAZ 2107 opens, the plug is unscrewed from the oil filler neck. This is done manually.
No special tools are required to unscrew the oil cap - On the crankcase of the VAZ 2107 there is a special hole for draining the oil, closed with a stopper. Under this hole, a container is installed to drain the mining, after which the drain plug is unscrewed with a socket head by 12.It is most convenient to unscrew the drain plug on the VAZ 2107 with a socket wrench with a ratchet
- Oil draining begins. Keep in mind that it can take 15–20 minutes to completely drain the grease from the motor.To drain the oil, you need a five-liter container and a funnel from a plastic bottle

Flushing the VAZ 2107 engine and changing the oil
As mentioned above, completely draining the lubricant from the VAZ 2107 engine is a long process. The problem is that even after 20 minutes of draining, the engine still has a working out. This point is especially relevant if the oil is very old, and therefore very viscous.
Such oil simply does not pour out of the small channels and openings of the engine. To remove this viscous mass, the car owner will have to flush the VAZ 2107 engine with diesel fuel.
Flushing sequence
An important point: after the liquid oil is completely drained from the VAZ 2107 engine, it is necessary to remove the old oil filter from the car and replace it with a new one. You can save on the quality of this filter, since it will be used only once, during flushing.
- The previously opened drain hole is closed again with a plug. Diesel fuel is poured into the engine through the oil filler neck. Volume - 4.5 liters. Then a plug is installed on the neck, and the motor is cranked for 15 seconds by the starter. It is impossible to start the engine completely. To increase the efficiency of flushing, the rear right wheel of the car can be raised by 15–20 cm using a jack.
- The drain plug on the crankcase cover is unscrewed again with a 12 socket wrench, and the diesel fuel is drained along with the dirt.
- After the diesel fuel is completely drained (which may take 10-15 minutes), the plug on the crankcase is tightened, and 5 liters of fresh oil are poured into the engine through the oil filler neck, after which the plug on the filler neck is tightened.

What kind of oil can be poured into a VAZ 2107 engine
The car owner, who for the first time decided to change the oil on his "seven", will inevitably face the question: what kind of lubricant to choose? This is far from an idle question, because there is a huge amount of motor oils on the modern market. From such an abundance it will not be long and confused. Therefore, it is worth understanding the types of motor oils and their differences.
Types of oils
Basically, engine oils are classified into three types:
- synthetic oil;
- semi-synthetic oil;
- mineral oil.
Now let's take a closer look at each type of oil:
- synthetic motor oils are the most expensive. You shouldn't be surprised at this: “synthetics” have excellent temperature parameters and viscosity. If the driver has filled in high-quality synthetic oil, he can be sure: it will not freeze even at -50 ° C, and this circumstance is very useful given our climate;
- semi-synthetic motor oils are a mixture of mineral and synthetic oils. "Semi-synthetics" do not have such a wide range of operating temperatures, however, there is one undoubted advantage: it is cheaper;
- mineral motor oils are the cheapest today. The reason is simple: the viscosity of these oils directly depends on the temperature outside. For example, in forty-degree frost, most mineral oils turn into a substance similar to plasticine.
The choice of oil for the VAZ 2107
Taking into account all of the above, it becomes clear: the choice of lubricant for the VAZ 2107 engine primarily depends on the climatic conditions in which the car is operated. If a car owner operates a car in a region with a positive average annual temperature, then he should use a simple and cheap mineral oil, such as LUKOIL TM-5.
If the car owner lives in a region with a temperate climate (which just prevails in central Russia), then it would be more expedient to fill in semi-synthetic oil. For example, Mannol Classic 10W40.
And finally, residents of the Far North and regions close to it will have to use exclusively high-quality synthetic oils. A good option is the MOBIL Super 3000.
How the oil filter VAZ 2107 works
When changing the oil for a VAZ 2107, car owners usually replace the oil filter as well. Let's try to figure out what kind of device it is and what it is. Oil filters are classified into three types:
- filters with modular casing;
- filters with a collapsible body;
- filters with a non-separable body.
The most expensive are the collapsible filters. But they also have the longest service life. When this type of filter becomes clogged, the car owner removes it, opens the housing, takes out the filter element and replaces it with a new one.
Filters with non-separable bodies do not last long, since they are disposable devices. As soon as the filter elements in such a filter become dirty, the car owner simply throws it away.
The modular housing filter is a hybrid of a collapsible and a non-collapsible filter. The modular housing is only partially disassembled, so that the car owner only has access to the filter element. The rest of the filter details remain unavailable.
The filter housing can be anything, but the "stuffing" of this device is almost always the same.
The body is always in the form of a cylinder. There are two valves inside: direct and reverse. And inside there is a filter element connected to a spring. Outside, each filter has a small rubber O-ring. It prevents oil leakage.
The filter element is made of special impregnated filter paper. This paper is folded many times, so that a kind of "accordion" is formed.
Such a technical solution is necessary to ensure that the area of the filtering surface is as large as possible. A direct valve allows oil to enter the motor when the main filter element is clogged. In fact, the direct valve is an emergency device. It lubricates the rubbing parts of the motor with crude oil. And when the engine of the car stops, the check valve comes into play. It traps oil in the filter and prevents it from flowing back into the crankcase.
Thus, the choice of an oil filter for a VAZ 2107 entirely depends on the wallet of the car owner. Anyone who wants to save money chooses a non-separable filter. Anyone who is not constrained in funds puts collapsible or modular devices. A good option here is a filter from MANN.
Modular devices from the CHAMPION firm are also in high demand among the owners of "sevens".
Well, if money is not enough, then you can take a closer look at disposable filters Nf-1001. As they say, cheap and cheerful.
About the frequency of replacement of oil filters
If you look into the operating instructions for the VAZ 2107, then it says that oil filters should be changed every 8 thousand kilometers. The problem is that mileage is far from the only criterion by which the wear and tear of a device is determined. To understand that the filter is worn out, you can use the engine oil control. If the car owner, checking the oil with a dipstick, sees dirt on the dipstick, then the filter is not working well and needs to be replaced. The style of driving also affects the life of the filter. If the car is driven too aggressively, then the oil filters become clogged faster. Finally, the operating conditions of the car. If the car owner has to constantly drive in heavy dust, then the oil filters will have to be changed very often.
Replacing the oil filter on a VAZ 2107 car
No special tools are needed to replace the oil filter on a VAZ 2107.
- After the old oil is drained from the engine and it is washed, the filter is unscrewed from its niche manually (in very rare cases, the device cannot be unscrewed by hand. In this case, it is recommended to use an oil filter puller).In the vast majority of cases, VAZ 2107 oil filters do not require special pullers
- The new oil filter is removed from the packaging. A little engine oil is poured into it (the body should be approximately half filled).The new filter must be filled with engine oil up to half of the housing
- The rubber ring on the filter housing is also lubricated with engine oil.The sealing ring on the filter is lubricated with oil to improve tightness
- After that, the filter is installed in its original place (and you will have to screw the filter into the socket very quickly, since otherwise the oil with which it is filled will spill out onto the floor).
So, changing the oil on a VAZ 2107 is not a super complicated technical procedure and even a novice car enthusiast who has at least once held a socket head and a knob in his hands can do it. All you need to do is follow the guidelines above exactly. And of course, you shouldn't skimp on engine oil and filters.
