Which gear oil is best for VAZ 2107

Most owners of the "Seven" fill the gearbox with transmission oil recommended by the manufacturer. In 2107, several types of gearboxes are installed at the plant. They all require high quality lubrication. Only in this case will the box work reliably and for a long time.

In the service book, the manufacturer indicates several viscosity levels:

SAE80W85,
SAE75W90,
SAE75W85.

Similar to motor oils, transmission oils, in addition to the viscosity coefficient, are divided into groups. In the VAZ 2107, professionals advise filling in:

GL-4,
GL-5.

The first group includes motor oils that contain a large number of special additives. This type is optimal for gearboxes with a large number of gears.

GL-5 brand oil is designed to lubricate rotating gears operating at a certain angle, that is, hypoid gears.

In the VAZ 2107, the rear axle gearbox has such a transmission. GL-5 is ideal for gearbox lubrication. The car manufacturer recommends replacing the lubricant in the gearbox together with changing the fluid in the manual transmission. Therefore, car owners use only one type of oil, pouring it into the box and gearbox.

In principle, no negative effect will occur. The properties of GL-5 allow it to be used in gearboxes. In addition, the compositions of this group were specially designed for use in extreme conditions.

Sequence of work

To do this you need to complete the following steps:

First of all, the oil must be warmed to operating temperature. This can be done by driving a few kilometers.
The car needs to be driven onto an overpass or inspection hole and put on the handbrake.
Find the drain and fill holes.
Clean the transmission housing and oil fill and drain plugs using a wire brush and then a rag.
Place a container under the drain hole to drain the used oil.
Using a hex wrench, unscrew the drain plug.
Drain the waste. You should be careful at this point, as the oil is very hot.
Clean the drain plug from dirt and screw it into place.
Carefully inspect the drained lubricant. If there is metal dust in it, then the gearbox requires repair.
Insert the grease gun into the oil filler neck and fill in the required amount of oil. Typically, liquid is added until it begins to flow out of the filler hole.
Screw the oil filler cap into place. The oil change is complete.

The same fluid is poured into the gearbox and rear axle gearbox. Therefore, it is better to change the oil in these units at the same time.

For those cars whose boxes have a dipstick for checking the oil level, the steps are as follows:

Find the drain cover on the gearbox.
Remove the rubber cap from the gearbox and clean it. At the same time, clean the breather, then return the cap to its place.
Place a container for waste fluid under the crankcase and unscrew the drain cap.
Wait until the oil drains completely.
Screw the drain plug into place.
Pull out the dipstick showing the oil level in the gearbox.
Insert a funnel where the dipstick was and add fresh fluid.
While pouring lubricant, you need to monitor the level using a dipstick.
The fluid level should be midway between the minimum and maximum marks.

Influence of viscosity grade

If the VAZ-2107 will be operated in temperate climate areas, where summers are constantly hot and winters are quite cold, then it is recommended to fill the manual transmission with all-season transmission fluid - SAE75W90. It can operate in a wide temperature range (-40/+45). Moreover, the performance qualities of the oil always remain unchanged.

When purchasing lubricant for manual transmission, you must take into account your place of residence. Each region has its own climatic conditions.

For example, SAE 80W85 can be operated in the range from +35 to -26 Celsius. Some regions require a wider range, so it is important to consider these values when purchasing.

How to check the oil level in a VAZ 2107 gearbox

Checking the oil level in the box is done as follows:

install the car on the inspection hole;
Use a rag and a wire brush to clean the plug and the surface of the box near the oil filler hole;
Unscrew the side filler plug.

The oil level should reach its lower edge. At the same time, you can check the condition of the oil.

If we talk about how much oil is in the VAZ 2107 box, you need to understand what modification of the box we are talking about. 1.35 liters of oil are poured into a four-speed gearbox, and 1.6 liters into a five-speed gearbox.

Choosing the right brand

Both beginners and experienced motorists are recommended to use oil approved by the manufacturer. This will allow you to avoid various problems associated with counterfeit products and defective problems in the operation of the gearbox. In this case, you should pay attention not only to the brand, but also to the parameters of the oil. In this regard, we will immediately name the recommended companies and product characteristics:

Reviews

Victor, Irkutsk region. I have a 2010 7, the basic version with a 1.5 liter engine. In terms of reliability, I was very pleased with the car, but only from the point of view of maintainability. Per 1 km the car costs 3 rubles! A very economical car, as simple as a donut. True, the same can be said about security. I use it purely for work needs, and I will never put my wife and children in this bucket.

Nikolay, Ryazan. VAZ-2107 was purchased in 2022, the total mileage is currently 133 thousand km. A car with a rusty body and a 1.5 engine is quite suitable for working as a taxi in poor road conditions. It’s also rear-wheel drive – you can play around in drifts on ice, fortunately there’s enough traction, because the car is very light and 75 horsepower is enough to spare.

Oil classes

Let's pay attention to the most popular classes of lubricants suitable for the VAZ-2107:

GL-4 - this type of lubricant contains a large number of additives that ensure efficient and reliable operation of the gearbox when driving at high speeds, but low torque, or when driving with high torque, but at low speeds
GL-5 - oil with this standard should be poured into the gearbox. It can also be poured into the gearbox, but only in harsh climatic conditions.

Classification of oils

On each canister of transmission oil for the VAZ 2107, certain characteristics are indicated, indicating the viscosity class and group.

Oil groups

To choose which oil to fill in the VAZ 2107 gearbox, you need to know the groups of these lubricant compounds:

GL-4. VAZ 2107 gearbox oil of this group contains many additives. Basically, such lubricants are used for cars with stepped gearboxes operating at high speeds with low torques, as well as those operating at low speeds with high torque.
GL-5. This oil for the VAZ 2107 gearbox is intended for so-called hypoid gears (gears rotate at an angle). In these models of domestic cars, the hypoid gear is located inside the gearbox, so only GL-5 grease can be poured into the gearbox. Such oil is also sometimes poured into the transmission, but only under severe operating conditions.

Viscosity grades

SPECTROL FORWARD

To choose which gear oil is best for the VAZ 2107, you need to decide on the viscosity class:

SAE75W90. This class includes semi-synthetic or synthetic oils that are suitable for all-season use. The lubricant can be used within the range from -40 to +35 degrees Celsius. Such oils can be used in cars that are operated in the harsh conditions of our country.
SAE75W85. This viscosity class is also suitable for all-season use in a box, and the temperature for maintaining performance characteristics varies from -40 to +45 degrees.
SAE80W85. Oils of this viscosity boil at +35 degrees and freeze at -30 or more.

You can read a separate article with detailed video instructions about changing the oil.

Mineral lubricants

The most important and perhaps the only advantage of mineral oils is their low price compared to synthetics and semi-synthetics. For example, a four-liter canister of mineral oil in a VAZ 2107 box costs about 400 rubles, and a similar canister of semi-synthetic oil costs more than 1000.

The lubricant composition has good lubricating properties, so you can drive it without replacement for up to 60-70 thousand kilometers. Moreover, in winter, such a lubricant hardens faster in the cold and makes it difficult to start a cold engine.

Semi-synthetics and synthetics

AGIP ROTRA MP

The only drawback of such transmission oil for the VAZ 2107 is the relatively high price compared to ordinary mineral water. On average, a canister costs from 1000 to 1500 rubles. The disadvantages are limited to this, but as for the advantages, these include the high-tech lubricant and the content of additives that reduce wear on transmission elements, extending the service life of the gearbox.

The freezing point of these oils is much lower, so they are suitable for use in severe frosts. You can release the clutch pedal a few seconds after starting the power unit and the gearbox will work normally. The lubricant warms up faster and returns normal fluidity compared to mineral lubricant.

Some say that synthetic transmission oil for the VAZ 2107 can squeeze out oil seals and leak from cracks. This is not true and if this really happens, it is a coincidence, and the real reason is hidden in the obviously worn-out gearbox.

Viscosity type

This parameter determines the operating temperature range supported by the oil. This parameter determines the temperature conditions under which the VAZ-2107 can be operated. So, let's consider suitable viscosity parameters for the VAZ-2107:

SAE75W90. This parameter marks synthetic and semi-synthetic oils intended for operation of the VAZ-2107 in any weather. This lubricant is suitable for regions with constantly changing climates. Temperature range – from -(minus) 40 to +35 degrees.
.SAE75W85 - this lubricant is also suitable for all-season use, but it also has a much larger range of supported temperatures - from - (minus) 40 to +45 degrees.
SAE80W85 is also a good option, but with a more limited temperature range - from - (minus) 30 to +35 degrees.

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.

Oil type

Mineral oil is the cheapest and mediocre oil. It has good lubricating properties, but only in warm weather, since in the winter season mineral water quickly hardens, which can cause problems with starting the engine. This lubricant is used mainly in trucks and old cars with high mileage. Mineral oil is replaced every 70 thousand km. Semi-synthetic - this oil can be considered the optimal choice for the VAZ-2107, taking into account modern trends. This is a relatively inexpensive lubricant with good lubricating properties. It can be recommended for the VAZ-2107 without any reservations.

Synthetic is the rarest and most fluid oil of all presented. It quickly penetrates the parts, provides them with effective lubrication and adequate cooling, and thereby protects the gearbox from overheating. This oil is best used for foreign cars, and will be a waste of money for the VAZ-2107.

When it is necessary to change or add oil in a “seven” box

You only need to add oil when the level is below normal. This can be done with a special syringe after first unscrewing the oil filler plug. Changing the oil in a VAZ 2107 gearbox is performed in the following cases:

After running 60 thousand kilometers. The manufacturer recommends changing the transmission oil at exactly this interval, but in fact it is better to do it a little more often - about once every 50 thousand kilometers.
When extraneous noise appears. Oil loses its properties over time, moisture and metal particles enter it, which accelerate wear of parts. Therefore, the first thing to do when a hum or grinding noise appears is to check and change the oil.
With a sharp change in color (blackening). If the gearbox oil is black, it needs to be changed urgently, regardless of the current mileage of the car.
When buying a used car. If you don’t know exactly when the previous owner last changed the transmission oil, do it immediately after purchase.

Delay in changing the oil will quickly lead to gearbox failure.
