Criteria for selecting VAZ 2101 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 and higher.
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 fill in with 10w-40.
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.
Engine tuning 2101
Description of the VAZ 2101 engine tuning process
Tuning a penny engine, or as they also say, boosting the engine of a VAZ 2101, is a risky business, taking into account what is written above and taking into account the general wear and tear of the engine, if this does not stop, then let's go... first, let's look at it from the point of view of increasing the engine displacement. This is the most affordable method to improve your engine, increasing power and torque throughout the entire range. We will also describe the option of installing sports camshafts, boring cylinder head channels, compressors, etc. in detail below. But given the fact that your engine is a used 2101, hanging too much on it is fraught with consequences. To increase the power of the VAZ 2101 engine, let's start with cars produced in 1970-1974; they are distinguished by the ability to install Niva pistons with a diameter of 82 mm from the VAZ 21213 Niva, thanks to the thick-walled cylinder block. To prevent the compression ratio 2101 from sagging (a puddle in the pistons 21213), you need to take Niva pistons with a flat bottom or lighter pistons 2112 and cut off the displacer from the pistons. With a standard stroke of 66 mm, the engine volume will be 1.4 liters. We will get an increase in power, but the engine itself will be very high-speed. The increase in engine volume of the VAZ 2101 produced after 1974 is somewhat different; in order to save metal, the cylinder block became thin-walled, the maximum possible piston diameter is 79 mm from the VAZ 21011 or 2105. The piston stroke is increased to 80 mm. implemented by installing a crankshaft from a VAZ 2103 and connecting rods with a reduced center-to-center distance (129 instead of 136) or installing pistons with a reduced compression height, produced by TRT. Disadvantages of short connecting rods - the angle of inclination of the connecting rod, the greater the angle of inclination, the greater the force it presses the piston against the cylinder wall, the resistance to movement increases, lubrication conditions worsen, the cylinder walls wear out, the connecting rod works under greater load (especially in the center of the connecting rod), engine reliability 2101 is decreasing. Among the advantages, we note a good cylinder filling rate at medium and low speeds, a more homogeneous mixture, and improved combustion. The disadvantages of TRT pistons are their lower strength compared to standard VAZ 2101, thermal load on the ring and the likelihood of piston burnout. Increased piston stroke to 84 mm. VAZ 2130 crankshaft, as well as use TRT pistons, connecting rods shrink to 134 mm.
Boring of VAZ 2101 engine
The crankshaft and boring of the VAZ 2101 engine will give you the following volumes: - larger diameter piston, standard stroke 1.3 liters. 79x66 (cylinder diameter X piston stroke) ~64 hp. Maximum torque is about 95 Nm at 3400 rpm We get an analogue of the 21011 engine - a larger diameter piston, a standard stroke of 1.4 liters. 82x66 (until 1974) Such VAZ engines were not produced in series; there is little information about the construction of such engines. This is explained by the fact that in order to adequately use such a motor, you need a reinforced bottom, forged pistons, selecting the desired top shaft, etc., plus everything needs to be properly configured. The maximum speed of the correct configuration is more than 9000 rpm. The service life of such an engine is about 20 thousand, depending on operation. - standard piston, increased stroke 1.5 liters. 76x80 ~70 hp Maximum torque is approximately 105 Nm at 3000 rpm Analogue of the VAZ 2103 engine on a low block. This option is the answer to all questions about how to improve the VAZ 2101 engine. - larger diameter piston, increased stroke 1.6 liters. 79x80 ~75 hp Maximum torque approximately 115 Nm at 3000 rpm Analogue of the VAZ 2106 engine on a low block - larger diameter piston, increased stroke 1.7 liters. 82x80 (until 1974) ~ 80 hp Maximum torque ~125 Nm at 3200 rpm The configuration is the same as the engine from the Niva 2101 on a low block - a larger diameter piston, an increased stroke of 1.8 liters. 82x84 ~80 hp (until 1974 onwards) Maximum torque ~135 Nm at 3000 rpm The 2103 engine is more suitable for this volume
Tuning cylinder head VAZ 2101
A good option for upgrading the VAZ 2101 engine by removing the roughness of the channels, polishing the cylinder head channels and the VAZ 2101 manifold reduces the intake resistance, the power of the penny engine increases by about 5-8 horsepower, and the torque increases throughout the entire range. To polish, you need to remove the cylinder head and wash it with a mixture of gasoline, kerosene and solvent. After that, take an electric drill, wrap a rag around the drill, and put some sandpaper on top. The collector is fixed motionless in a vice and we begin sawing; after the bend of the collector, the same is done on a flexible rod. When modifying the cylinder head on a classic, it is necessary to grind off the protrusion at the connection of the cylinder head and the exhaust valve (about 3 mm), after which we use the same tool until we can insert the valve, after passing through all the channels and cutting off the bushings in them, we polish the channels from the seat side. When With additional boring of the channels, the VAZ 2101 engine is capable of producing about 75 hp. It is also recommended to use T-shaped valves on classics instead of tulip-shaped ones.
Camshaft for classics
Let me point out right away that the popular option of modifying the VAZ 2101 engine by installing a Nivov camshaft on a classic will not suit racers; the result will be a low-end VAZ engine, the tops will sag, and this is unacceptable. Optimal rollers for the VAZ 2101 with a modified cylinder head and increased volume to 1.5-1.6 urban STI-2, more sporty STI-3 or STI-4 sports wide-phase, the bottom may sag on it, but the engine will easily spin at more than 7000 rpm /min. We select a camshaft on a VAZ for a standard VAZ 2101 or VAZ 21011 engine, a good choice is Nuzhdin 10.5 256 or Nuzhdin 11.2. A correctly selected camshaft for 2101, as well as a modified head, when boosting the VAZ 2101 engine can show more than 80 hp .
Compressor for VAZ 2101
The market offers ready-made compressor installation kits for the VAZ 2101, for example an auto-turbo compressor with a pressure of 0.5 and 0.7 bar. The 0.5 bar auto-turbo compressor is installed with minimal modifications. When installing a compressor on a VAZ with a pressure of 0.5 bar on a modified cylinder head with a volume increased to 1.5-1.6 liters, the car will produce more than 120 hp. With standard volume up to 90-100 hp. The installation may reduce the service life of the VAZ 2101 engine.
Rotary engine on VAZ 2101
An extreme measure because the price of a rotary engine for a VAZ will force you to immediately discard this idea. Among the rotary engines, the classics include the VAZ-411 RPD with a power of 120 hp, and the VAZ-413 with a power of 140 hp. and VAZ-415 with a power of 140 hp, but lighter. A VAZ-411 RPD with a power of 120 hp was installed on a penny. with it the car was traveling about 180 km/h. The disadvantages of the VAZ RPD are its low service life (with 125 thousand km declared by the manufacturer), high fuel consumption and high oil consumption (up to 1 liter per 1000 km).

Engine oil
Any big thing can be done if it is divided into many small tasks - Henry Ford once said. And in truth, it would seem that such a job as changing engine oil can be completed without haste if you prepare the necessary tools and consumables in advance.
Required Tools
Engine oil change period (interval or interval)
Manufacturers (not only VAZ but also other brands) take the replacement interval of 15 thousand km as a basis and recommend “relying” on this figure. However, many car enthusiasts perform maintenance earlier, already at 10 thousand. They justify this with terrible roads and the quality of fuel and lubricants.
Recommended services for selecting automobile oils
If you already have preferences in the brand, then everything is even simpler. It is enough to go to any service for selecting automobile oils of the desired brand and the manufacturer will select the oil that will be compatible with your engine. The table contains the most popular brands and selection services from these brands. We go to any of the sites in the table and select the make, model of the car, engine and year of manufacture.

In order for the engine to work properly, it is necessary to monitor the serviceability of its parts and regularly change the oil filter and oil. For the classic VAZ 2101 model, this procedure is simple, so any car enthusiast can do the replacement. To do this, you need to purchase consumables and follow the instructions.
Which oil is better to choose
To choose the right oil, you need to know its main characteristics and the possibility of use on the VAZ 2101. Any lubricant consists of a base oil base and additives that give it certain properties. There are additives that increase the viscosity and stability of the film formed by oil, and have detergent properties.
Based on the basic basis, lubricants are divided into: synthetic, semi-synthetic and mineral. Synthetic ones have low viscosity and are divided into PAO synthetics and hydrocracking. The first ones are manufactured using complex technology, the highest quality and most expensive. The second ones have lower quality, simpler production, and are based on petroleum products.
Mineral oils are made from natural raw materials – petroleum. Thanks to simple manufacturing technology, they have an affordable price. The disadvantage is a short service life: they quickly lose their properties and are susceptible to oxidation. At low temperatures they quickly thicken and become viscous.
Semi-synthetics are a mixture of the first two types of lubricating fluids. Synthetics are added to the mineral base. As a result, a product is obtained with characteristics better than mineral water, but cheaper than synthetic analogues. The best combination of price and quality.
For modern lubricants, there is no concept of seasonality. If earlier oils with a lower viscosity were chosen for the winter season, and thicker ones for the summer, now they are all-season. For the VAZ 2101, the best option would be semi-synthetic all-season oil 10W40.
Reasons and frequency of oil changes
How well it will perform its functions depends on the condition and quality of the engine oil:
Oil filter
An important component in the lubrication system of any car. Motor oil lubricates rubbing parts, and the oil filter retains metal debris (crumbs, sawdust, dust, sand and other debris) and in this way cleans this oil.
When should you change the filter?
Each filter must be replaced along with changing the engine oil. They must be considered one mechanism and must also be serviced together. Recommendation for replacement every 10-15 thousand km or once a year.
Which filter should you choose?
For the Lada "Kopeyka" oil filters cost a reasonable amount of money. Below is a suggested list with filters that are suitable for a penny. Sorting from cheap to expensive. At the same time, the cheapest costs a little more than 1 dollar and the expensive BOSCH
- Industrial business M-005
- LA OF 3102(920/21)
- Industrial business M-001
- Zollex Z-104
- WIX WL7067-12
- BOSCH 0 451 103 033
Maintenance
Considering the design of the internal combustion engine, the manufacturer recommends the following maintenance schedules:
| Maintenance object | Time or mileage (whichever comes first) |
| Valve train chain | replacement after 100,000 km |
| Battery | 1 year/20000 |
| Valve clearance | 2 years/20000 |
| Crankcase ventilation | 2 years/20000 |
| Belts that drive attachments | 2 years/20000 |
| Fuel line and tank cap | 2 years/40000 |
| Motor oil | 1 year/10000 |
| Oil filter | 1 year/10000 |
| Air filter | 1 – 2 years/40000 |
| Fuel filter | 4 years/40000 |
| Heating/Cooling Fittings and Hoses | 2 years/40000 |
| Coolant | 2 years/40000 |
| Oxygen sensor | 100000 |
| Spark plug | 1 – 2 years/20000 |
| Exhaust manifold | 1 year |
With timely cleaning, the lubrication, cooling and fuel supply system operates longer without major repairs.
Advantages and disadvantages
In the first years of operation, the 2101 engine revealed the following shortcomings:
- noisy operation of the chain drive;
- increased gasoline consumption in the engine due to defects in carburetors;
- frequent ignition adjustments;
- Difficult adjustment of valve clearances.
Solex carburetor
However, a cylinder head improved with a camshaft, an improved intake manifold and an exhaust manifold of the simplest design compensated for these shortcomings. A little later, DAAZ Ozone carburetors were developed, replacing which made it possible to improve the characteristics of internal combustion engine modes.

Malfunctions: causes, elimination
Unlike motors with a timing belt drive, the 2101 valve bends much less frequently. The main malfunctions of the internal combustion engine are:
| Breaking | Cause | Elimination |
| Blue smoke | rupture of valve seals, bushings and cylinder head gaskets, wear of rings | replacement of consumables and seals |
| Engine overheating | Fan or thermostat failure | replacement of attachments |
| Oil consumption increases | leaks in valve covers, worn out pistons/cylinders | replacing gaskets, installing the next repair size of pistons and rings |
| Knock | crank bearings, connecting rod bearings, increasing valve clearance | replacement of consumables field of qualified diagnostics |
The speed limit of “kopecks” with 2101 engines was 145 km/h, and the car accelerated to “hundreds” in 18–20 seconds in a straight line.

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.
Equipment and tools
What equipment will you need to change the oil:
- Syringe for filling oil.
- Watering can for pouring oil.
That, in fact, is all that is required.
Design Features
Initially, at the design stage, a feature for the engine was the overhead camshaft:
- The piston stroke decreased by 5.5 mm compared to the Fiat 124 standard;
- the cylinder diameter increased by 3 mm.
This modernization ensured acceleration and rapid acceleration. In addition, the 2101 engine had the following design nuances:
- timing chain transmission;
- unfinished carburetor models;
- major overhaul after 20,000 km.
Valve train chain
Immediately after the release of the first internal combustion engine of this series, the manufacturer AvtoVAZ released a manual in which it indicated which oil to fill in the engine and provided a description of the internal combustion engine parameters to increase the service life of the engines. Thus, the owners of the next three generations of engines had no questions about what oil to pour and in what quantity.
Timing mechanism
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.
