Criteria for selecting VAZ 2105 oil
All oils are selected based on compliance with SAE, ACEA, API.
- In terms of composition, it is optimal to use semi-synthetics for used VAZs.
- ACEA A3/B3-B4.
- API SF for models up to 2000, for more recent API SG, SJ. VAZ 2105 was produced until 2010 inclusive.
AvtoVAZ offers the following table to select the appropriate viscosity:
| Minimum engine cold start temperature, °C | Viscosity grade according to SAE J 300 | Maximum ambient temperature, °C |
| -35 | 0W-30 | 25 |
| -35 | 0W-40 | 30 |
| -30 | 5W-30 | 25 |
| -30 | 5W-40 | 35 |
| -25 | 10W-30 | 25 |
| -25 | 10W-40 | 35 |
| -20 | 15W-40 | 45 |
| -15 | 20W-40 | 45 |
But most often, drivers pour 10w-40 into models with significant mileage, into more recent 5w-30.
Information on viscosity for a specific engine can be found in the motor oil interchangeability catalog: https://www.northsealubricants.com/en/oil-advisor
The catalog can be trusted, the data is taken from car manufacturers. In this case, you can choose not only oil for the engine, but also for the gearbox, power steering, brake system, and cooling system. That is, all liquids.

Classification of motor oils
The manufacturer's recommendations do not regulate the type of oil applicable to the "Seven" engine. Mineral, synthetic and semi-synthetic oil can be poured into the engine if it meets the quality requirements.
Motor oil canisters are marked (for example, “API SJ” or “API SG/CD”), which informs about the quality of the product. When choosing oil, this is what you should pay attention to.
The abbreviation API ( American
Petroleum Institute )
means “American Petroleum Institute.” This is an American non-governmental organization that provides regulation of issues related to the gas and oil industries. One of the areas of API's work is the development of standards and recommended practices for the oil and gas industry.
Motor oil is standardized according to the following indicators:
- toxicity;
- washing ability;
- corrosive activity;
- effectiveness of protecting parts from friction;
- the amount of deposits remaining on parts over the period of operation;
- temperature characteristics.
The letters “S” and “C” mean that the oil is intended for gasoline or diesel engines.
The letter after "S" or "C" indicates the quality of the engine oil's performance characteristics. The markings are in alphabetical order. The further the letter is from “A”, the better the characteristics of the oil.
Oil suitable for VAZ 2107 is minimum “API SG/CD”.
Note: the SAE methodology (type “5W40” qualifies oil only by viscosity indicators. This classification does not take into account performance characteristics and quality.
Oil volume in the VAZ 2105 engine
| Engine | hp | Year of release (beginning-end) | Engine oil volume, l | |||
| 1.2 | B | VAZ-2101 | 64 | 1981 | 1999 | 3,75 |
| 1.3 | B | VAZ-2105 | 64 | 1980 | 1993 | 3.75 |
| 1.45 | B | VAZ-2103 | 77 | 1976 | 1988 | 3.75 |
| 1.6 | B | VAZ-21067 | 80 | 2010 | 2010 | 3.75 |
Determining the oil change period
The presence of an oil pressure sensor on the power unit of the car greatly simplifies the determination of the right moment, upon the occurrence of which a planned replacement of the lubricant in the VAZ-2107 is necessary. For a more accurate timing, you need to pay attention to the oil pressure in different engine operating ranges. Basically, when the lubricant disintegrates (decomposes), the VAZ-2107 oil pressure indicator (installed on cars produced before 1988) indicates excess pressure in the system during startup and prolonged operation.
This occurs due to the liquefaction and boiling of the oil in the engine crankcase. If the vehicle does not have an oil pressure gauge, you should refer to the car manufacturer's instructions. The AvtoVAZ technical department recommends replacing the lubricant in the power unit every 6,000 kilometers when driving short distances and after 10,000 kilometers when driving regularly over long distances.
When replacing, it is best to fill in the exact brand of oil that was poured into the crankcase of the VAZ-2107 power unit before.
It is not recommended to fill old, worn-out engines with synthetics, because it washes away deposits that fill microcracks in the oil sump.
After running in the factory engine, it is better to immediately fill it with synthetic oil, since in a good engine, modern synthetic lubricant will prevent it from overheating and thereby significantly increase its service life.
Regardless of what distances the car has covered, if you replace consumables and operating fluids on time, then it will serve reliably for many years and delight you with its reliability.
In this article you will learn how to change the oil and what is associated with it. This will extend the life of the vehicle and promote proper operation. All work can be divided into several stages, which will be discussed below.

A complete description of the internal combustion engine parameters is contained in the official manual of the manufacturer. It states that opposite the valves in the engine pistons there are slots that ensure the safety of the internal combustion engine in the event of a timing belt break - the piston will not be able to “meet” the valve physically. The user simply replaces the rubber product; no major repairs are required.

When to change the oil
When the time comes for the VAZ 2105, you must follow the manufacturer's instructions. So:
- If the car is new, then you can follow the manufacturer's recommendations.
- If the car has significant mileage, then you need to learn how to determine these terms yourself.
- In a new car, the manufacturer recommends changing the oil after 15,000 km.
But if the car is no longer new, then this period should be reduced to 10,000 km or even 7,500 km.
Attention: In any case, when measuring the oil level in the crankcase, pay attention to the transparency of the oil and its viscosity. If the oil has darkened or even turned black, and the viscosity is no longer the same to the touch, then it is better to change the oil ahead of time.
The timing of an oil change is greatly influenced by the condition, quality of the gasoline you drive and the quality of the oil itself. If you have to change the oil on a VAZ 2105 engine, follow the instructions below.
What cars were equipped with ICE 2105?
This modernization could not satisfy users of the domestic automobile industry. The main drawback was the regular breakage of the timing belt, AvtoAZ management reduced production volumes, then removed the 2105 engine from production, so only three modifications of the Zhiguli were equipped with the engine:
- 2105 sedan;
- 2104 station wagon;
- 21072 sedan.
Currently, tuning for the engine of this series is not difficult, but among the operating fleet of Zhiguli “fives” with the “native” engine there are very few left.
