ZMZ 405 high fuel consumption

The so-called “105th” is a continuation of the GAZ 3110. This “Volga” was the brainchild of the Gorky plant, where it was assembled from 2004 to 2009. It has only a sedan version and belongs to a middle class car. Since 2006, “31105” has received a number of additions, including those related to the engine compartment. In particular, the sedans were equipped with American Chrysler engines and ZMZ 406 power plants suitable for Euro 3. Almost the entire assembly was carried out for domestic car enthusiasts. Only small shipments were sent to the CIS and some states of the Middle East.

GAZ 31105 (ZMZ 406) injector

Fuel consumption rate per 100 km

This version is distinguished by an engine from the Zavolzhsky Motor Plant and has a volume of 2.3 liters. This engine is capable of producing 136 hp. Works exclusively with a manual transmission and consumes 92 gasoline. The driving axle is the rear axle. Overcomes the barrier of 100 km/h in 14.5 seconds. Maximum acceleration is 163 km/h. Consumption: in urban conditions - 13.5 l, on the highway - 8.8 l.

Real consumption

Andrey, Cheboksary. I still think why I swapped the VAZ “ten” for a “Volga” 31105 2.3 liter 2005. There seems to be a lot of space inside, and on the highway I can reach 160 km/h without question. But the consumption of 13.2 liters in the city negates all the advantages. It's just a sedan, not a truck, to pull so much out of your pocket.
Nikolay, Saratov. I don’t understand those who complain about the 105th Volga. I myself had one from 2006 with a volume of 2.3 liters. The engine, although noisy, practically does not misbehave. It works properly, and the consumption of 12 liters is slightly higher than on budget foreign cars or Tolyatti basins.
Maxim, Tver. The 406th unit is considered a “workhorse”. It feels great in winter, although it won’t start in -26 degree weather. It consumes 12-14 liters in cold weather, depending on the operation of the stove and the road situation. In summer, 11.5 liters of gasoline in mixed mode is enough.
Alexey, Nizhny Novgorod. I worked for three years on 31105 with a Trans-Volga engine. I got a Volzhanka 2007 model. 2.3 l. There are very few complaints about the power plant. I can rant about the paintwork, but that's another story. And so I pour 92 gasoline. It turns out 12.4 liters in a free city and 13.5 in traffic jams.
Alexander, Murom. Although my Volga is still far from being an SUV, it takes on broken primers without difficulty. Over the summer I went into the forest about 5 times, and each time it rained. The car pulled smoothly, as if not noticing the dirt. The engine in this mode consumed 14.2 liters per hundred. As soon as I got on the asphalt and switched to a cruising speed of 120 km/h, the consumption dropped to 10.2 liters. Build 2007.

GAZ 31105 Chrysler 2.4

Information from the manufacturer

The model with an American unit from Daimler Chrysler began to be assembled in 2006. The modification has a volume of 2.4 liters and produces 137 horsepower. It also works with a manual transmission and only accepts gasoline. It hits the 100 km/h mark in 13 seconds. Maximum acceleration is up to 178 km/h. Consumption: in urban conditions - 13.7 l, on the highway - 7.8 l.

Owner reviews about actual consumption

Konstantin, Moscow. I took a Volga with an imported 2.4 engine that was far from new, but for commuting it couldn’t be better. I ride exactly 122 km a day. This takes a little more than 10 liters, despite the fact that the highway takes 100 km and the city 22. In winter, of course, you have to fill in 1.5-2 liters more. Warming up with the stove is of no help. Year of manufacture – 2008.
Pavel, Arkhangelsk. The 105th Volga served me for 4 years with a 2.4 L Chrysler 2009 installation. I can’t say that somewhere it was possible to save on fuel. It poured almost 15 liters in the winter in the city. But such numbers don’t scare me away. A friend has a BMW 320. So the German one has 13.5-14 liters.
Ruslan, Shakhunya. Volga 31105 on 2.4 Chrysler 2008. The car is capable of reaching a height of 200 km per hour. It goes like a cruiser on the waves, but it’s better not to accelerate more than 170 km per hour, as the consumption becomes crazy. Optimal speed: 120-130 km per hour. In this case, the consumption will be up to 9 liters.
Nikolay, Rostov. Who doesn’t care about the noise in the cabin and doesn’t irritate the mechanic, the Volga 31105 will be like its own. But I couldn’t get along with her. I spent a year driving a GAZ with an American 2.4 liter engine. There is a lot of space, it picks up speed smoothly. In terms of consumption, I won’t say what it swallows: the city 40-70 km/h consumes 11.2 liters, and the highway – 8.9 liters.
Alexey, Kazan. This tank with the heart of Chrysler can easily make a Priora or the same VAZ “ten” from a standstill. I got a 2008 Volzhanka with 137 horsepower. I fed her 95 gasoline. In traffic jams at a speed of 20 km per hour I ate the most - 14.5 liters. And so, without aggravating circumstances, it comes out to 11.7 - 12 liters per hundred square meters.

Fuel consumption of the Gazelle 406, carburetor - different sources provide different data. In the article we will look at what types of engines there are for the Gazelle 406, and how they differ in key indicators: fuel consumption per hundred kilometers, advantages and disadvantages, factors that affect fuel consumption and how, is it possible to reduce the number of liters of fuel consumed.

Pressure and emergency oil pressure sensors for ZMZ 405, 406, 409 engines

In order to monitor the pressure in the lubrication system of the ZMZ 405, 406 and 409 engines, two separate sensors are provided. One of them records the pressure value, and the second reacts to its critical drop.

Characteristics, design and principle of operation of the oil pressure sensor

The oil pressure sensor (OPS) is used to measure the lubricant pressure in the system. ZMZ power plants use MM358 type sensors with the following characteristics:

working element - rheostat;
rated voltage, V - 12;
rated current, A - 0.15;
operating range, kgf/cm2 – 0–6;
resistance in the absence of pressure, Ohm - 159–173;
size of the landing thread, in inches – ?.

Pressure sensor MM358

The design of the MM358 pressure sensor consists of:

housings with fittings;
membranes;
pusher
rheostat;
rheostat drive elements.

The basis of the sensor design is a rheostat

The MM358 sensor works together with the pressure indicator located on the vehicle’s instrument panel. It has an electromechanical design that responds to changes in sensor resistance.

The oil pressure sensor works in tandem with a pointer located on the dashboard

The operating principle of the MM358 sensor is as follows: when the engine is not running, there is no pressure in the lubrication system. The resistance of the sensor, in accordance with its characteristics, is 159–173 Ohms. When the power unit starts, the pressure increases, and the oil begins to act on the membrane, bending it inside the housing. By bending, it moves the transmission lever through the pusher, which, in turn, moves the rheostat sliders to the right, reducing the resistance of the sensor. The pointer reacts to this decrease by moving the arrow to the right.

Characteristics, design and principle of operation of the emergency oil pressure sensor

The emergency sensor is designed to inform the driver about a drop in oil pressure in the system to critical levels. In power units ZMZ 405, 406 and 409, emergency oil pressure sensors of type MM111D or similar are installed, manufactured under catalog numbers 2602.3829, 4021.3829, 6012.3829. These are contact-type devices, the operating principle of which is based on the closing and opening of contacts.

Sensor type MM11D

Characteristics of the MM111D sensor:

working element - diaphragm;
rated voltage, V - 12;
response at pressure, kgf/cm2 – 0.4–0.8;
size of the landing thread, in inches – ?.

A spring-loaded diaphragm is located inside the device body. A contact plate is attached to it, which in the non-operating state is closed with the body (ground) of the sensor. While the engine is running, lubricant under pressure enters the housing through a special hole and pushes back the diaphragm. The contacts are then opened.

The main element of the sensor design is the membrane

The emergency pressure sensor works in tandem with a signaling device, which is located on the instrument panel. It is made in the form of a red butter dish. When we turn on the ignition without starting the engine, the oil can should burn. This indicates that voltage is applied to the sensor, but there is no pressure in the system. 3–5 seconds after starting the engine, the pressure in the system increases and reaches operating values. The oil acts on the diaphragm, the contacts open and the alarm goes off.

Gazelle 405 injector: characteristics, operating features

The Gazelle 405 car with an injector engine is equipped with a new fuel supply system, which allows for more economical consumption and distribution of fuel. Let's consider the main qualitative characteristics of this engine model, operating principles, and also determine the advantages and disadvantages of using a fuel injection system.

Engine	Consumption (highway)	Consumption (city)	Consumption (mixed cycle)
2.4 (gasoline)	12 l/100 km	16 l/100 km	14 l/100 km

GAZ-31105 with ZMZ-406 engine

The transitional version from the ZMZ-402 carburetor engines is the more modern 2.3 liter ZMZ-406 engine. For GAZ-31105 vehicles, only engines with distributed fuel injection were installed, developing a power of 131 hp. and a torque of 188 Nm. These motors were installed from 2004 to 2008, after which they were replaced by the more powerful ZMZ-40525.

Reviews about the fuel consumption of the GAZ-31105 with the ZMZ-406 engine

Maxim, Nizhny Novgorod. What captivates me about the Volga is its cross-country ability. The engine power and ground clearance are enough to drive along the most rugged dirt roads. Consumption is of course bad if you drive through mud - 14-16 liters, like from a bush. But if on the highway, then it’s normal - on average 10 liters per 100 km comes out.
Alexey, Murmansk. Three years ago I sold the VAZ-2110 and bought a GAZ-31105. On the one hand, the interior is much larger - what we needed for the family. But on the other hand, the barge is just kind of clumsy, its dimensions are huge, you can’t park anywhere properly, and its consumption is high - in the city it’s from 13 to 14 liters, 4 liters more than the “ten”.
Anton, Ust-Kut. The car was bought in 2008, the “rogue” configuration, i.e. completely naked. I was persuaded to buy a used Japanese car, but I decided to buy a new car - I don’t have to worry about repairs, that’s all. There were no particular complaints, except for gas consumption - it eats it up like a cow, 13-14 liters in the city - this is still a normal figure.
Alexander, Cheboksary. I have been driving my Volga -31105 since 2006 for almost 10 years. If your hands grow where they need to and you take care of the car, there won’t be any problems, guaranteed. The main thing is to remember to add oil to the thresholds at least once every 1-2 months so that they do not rot. Yes, the consumption is higher than that of VAZs - I got 13 liters in the city in the summer and 15 in the winter, about 10 liters on the highway. But keep in mind that the car weighs almost one and a half tons and has a 2.3 liter engine.
Andrey, Saratov. I will say this - the 406 engine that is installed on the Volga is one of the most successful domestic engines. No whims, no surprises - it starts even at -30 below zero, pulls properly, easily consumes 92 gasoline. You won't get any dynamics from it - but then there are no problems either. In winter, consumption is from 12 to 14 liters - depending on the cold and road conditions; in the summer in the city I have 11.5 liters.
Nikolay, Tver. In 2010, I bought a five-year-old GAZ-31105 with a ZMZ-406 engine. The quality of the paintwork and assembly sucks, but by the way there are practically no complaints about the engine. The AI-92 always ran without problems (compared to the AI-95 there is no difference at all) - it pulled properly. On the highway the consumption was about 10 liters, in the city from 12 to 14 liters, depending on traffic jams.
Konstantin, Omsk. For my budget, there was only one choice - the domestic auto industry. But after looking at five TAZs with their wretched and flimsy interior, I still decided to take the Volga. I bought it at a dealership in 2006 - I figured that the new one would last at least a couple of years without any problems. Motor ZMZ-406, I read that it is an analogue of the SAAB engine - the spare parts fit exactly the same. By the way, I have a derated one, 130 horsepower, but it pulls just right. Consumption is within reasonable limits - highway is about 10 liters, city up to 14.5 liters, no more.
Stanislav, Krasnodar. My father also bought the GAZ-31105 - for him, the Volga is still a legend of the Soviet automobile industry. I had a VAZ-21103, it was constantly breaking down, after my father gave me his Volga (with a mileage of 60 thousand km) I couldn’t get enough of it - it didn’t break down!!! In reality, there were no such problems as with the basin at all - only small things, the main thing is not to forget to lubricate the main components, especially the suspension. The iron is good, thick, but if you don’t lubricate the thresholds, they will rust. The engine is also decent - 130 horses, but the volume is 2500 cubic meters, just right for the Volga. In terms of consumption, many write that it eats like a cow. The engine is 2.5 liters - my consumption is from 11 to 14 liters in the city. A lot of? And how much should it be, if the TAZ more than once reached 10 liters in the city, with a 1.5 liter engine.

Operating principles of an injection engine

An injector is a special system for injecting fuel into a car engine. Unlike the operating system of a carburetor engine, here fuel is forcibly injected into the cylinder using injectors. Because of these features, cars with such systems are called injection.

When the engine is in working condition, the controller receives information about such indicators as:

crankshaft position and speed;
antifreeze temperature;
vehicle speed;
all uneven road surfaces;
presence of malfunctions in the motor.

Location in power units ZMZ 405, 406, 409

In ZMZ motors, the location of both sensors is identical. You will find them in the upper left part of the cylinder head (as viewed from the interior) above the exhaust manifold. And while the emergency sensor may not be immediately visible, the oil pressure sensor is instantly identified by its barrel-shaped body.

Pressure and emergency oil pressure sensors are located in the upper left part of the cylinder head

Both sensors are screwed into one forked fitting (tee), which is screwed into the cylinder head and connected to one of the oil channels of the lubrication system. Power wires are connected to the sensors.

Advantages and disadvantages

Unlike carburetor engines, engines with an injection control system can reduce fuel consumption, simplify and improve the quality of Gazelle engine control, and meet all requirements for the composition of exhaust gases

. There is no need to manually adjust the fuel supply system.

But there are also some disadvantages of using injection engines: a significantly high price, if they break down they cannot always be repaired, the fuel must only be of high quality. If you have little experience in repairing Gazelle cars, it requires constant contact with special service stations, which leads to additional costs.

GAZ-31105 with Chrysler engine

In 2006, the GAZ-31105 car received an imported Daimler Chrysler 2.4 liter gasoline engine. Thanks to its successful design, the engine was quite popular and about 30% of all Volgas since 2007 have been equipped with this particular engine. Compared to the basic version, it has been slightly modernized - power has been reduced from 150 to 137 hp, in order to increase torque to 224 Nm. The reduction in power did not affect the dynamic characteristics and efficiency - they were higher than those of the ZMZ engine.

Fuel consumption rate for GAZ-31105 with a Chrysler engine per 100 km

Ruslan, Rostov. The fact that ours finally thought of installing imported engines is only a plus. I heard that KamAZs are equipped with imported turbodiesels, and it just turns out to be a fire. It’s the same with the Volga - with a Chrysler engine it’s a completely different car. Yes, the consumption is serious - if in normal mode it’s 12-13 liters, then with plugs it’s still 15-16 liters, after all, it’s an American engine. But the dynamics are comparable to any domestic auto industry.
Nikolay, Kazan. I live in the suburbs, so the travel mode is 20% city, 80% highway. I bought the Volga about three years ago – it’s a good and cheap version of a C-class car. The interior is spacious, rides very smoothly both on the highway and in the city, and is inexpensive to maintain. In mixed mode, I get even less than 10 liters per 100 km - 20 liters of gas is enough for four trips to work and home (which is 30 km one way). By the way, the engine is not ours, but an imported one, 2.4 liters.
Alexey, Balashikha. I work in Moscow, service vehicle - VOLGA 31105, with a Chrysler engine, 2400 cm3. The car, although inexpensive, is very good for the money - especially the engine. For 4 years I have not had any complaints about the engine. The consumption is decent - up to 16-17 liters in Moscow, but I can’t get more than 13 liters myself.
Konstantin, Astrakhan. GAZ-31105, 2.4 “Chrysler” 132 hp, 2009. A real cruiser - on the highway 150 km/h it goes calmly, the main thing is that the Shumka is good, otherwise you sit as if in the center of a hurricane. I drove at 170 and even 200 km/h - but then the consumption turned out to be under 20 liters. And if you go 100-120 km/h, then no more than 9.5 liters per 100 km, in the city 13-14 liters.
Pavel, Shakhtinsk. I drove a Volga with an American 2.4 liter engine for about a year. It seems to be a good car - there is a lot of space, gasoline consumption is adequate (highway 9 liters, city 13 liters), but even a used Japanese car is much more interesting. That’s why I sold the Volga and got myself a foreign car – now I don’t regret it at all.
Anton, Novosibirsk. I’ll say this – the Volga is not an acquired taste. The purchase of this car cannot be called a reasonable choice - just like the purchase of any domestic car. Yes, the option with the Chrysler engine is the most sane - but even despite all the advantages of the engine, our ugly assembly spoils the whole impression. On the highway the consumption is 9 liters, in the city from 11 to 14 (in winter), but if you don’t make noise, you can become deaf at speeds of more than 90 km/h. But the paint on the bumpers comes off from Karcher even at the car wash - what can we say about the pebbles from the road???
Vladislav, Rostov-on-Don. If you take the Volgarik, then only with a Chrysler engine. Trans-Volga engines are not even close to it. Consumption is from 11 to 13 liters, if you shoot - then 14-16 liters. However, six months later I installed HBO and didn’t bother at all.
Denis, Novosibirsk. The car is not actually mine - we bought it for my grandfather. He is a fundamental fan of Volgas, before that he drove the 29th, but it completely fell apart, so they chose the grandfather 31105 with the Chrysler engine. By the way, my grandfather immediately didn’t want to take it with an American engine, they barely persuaded him. Consumption is highly dependent on many conditions - from weather and road traffic to wind and the location of stars in the sky. On the highway from 9 to 15 liters (if you drive 150 km/h), in the city - from 13 in summer to 25 in winter (1-2 gears in heavy snowfalls).

What factors determine fuel consumption?

The main factors affecting fuel consumption on a Gazelle with a 405 engine are:

driver behavior while driving;
It is necessary to periodically check the condition of the wheels. Let there be more pressure in the wheels than the lack of it;
engine warm-up time;
additional parts that drivers often put on the car body;
technical condition of the car;
an empty car consumes less fuel than a loaded one;
inclusion of a large number of additional equipment.

ZMZ engine oil. Little trick

Polytrafic 10w-40 oil
This was suggested to me by the Elf employees themselves. According to a very simple American classification, ZMZ engines fall into the category - light truck. That is, light trucks, or in other words, commercial vehicles. This means that they can be filled with commercial grade oils. What does this mean translated into Russian? This is an oil intended for commercial vehicles with high mileage. Allows you to increase the interval from replacement to replacement. These oils contain a double package of additives. There is only one drawback: since they are used for truck engines, the manufacturer produces them in 20 liter cans. That is, this canister is enough to fill a gazelle or patriot for 3 times. Therefore, people have a question of storage. Otherwise, this is the best option, both in terms of price per liter of oil and its characteristics. The viscosity of this oil is 10-40. Product name Polytrafic 10w-40. This product also has approvals from almost all leading truck manufacturers, both for gasoline and diesel engines.

What can be changed

Fuel consumption will increase significantly if you constantly exceed the permissible driving speed, often move away sharply, while accelerating too much or pressing the brake pedal sharply.

If the car is in a technically faulty condition, then the engine does not operate at full power and the fuel simply, as they say, “flies down the drain.”

Such auxiliary parts as a stove, radios or other audio systems, air conditioners, always-on headlights, wipers, even the use of winter tires affect fuel consumption. So , for example, turning on the high beam increases the amount of fuel consumed by the Gazelle by more than ten percent,

using air conditioning for a long time - by 14%, and driving with windows open at speeds exceeding 60 km/h - by more than 5%.

From the above, we can conclude that before wondering why the gasoline consumption of your Gazelle has increased, analyze all your actions related to the operation of the vehicle, check the serviceability of the car engine, inspect the fuel tank, and, if possible, eliminate all problems, reduce to minimize the number of factors affecting fuel consumption.

Checking the emergency oil pressure sensor

To check the device you will need:

slotted screwdriver;

key to 22;

ohmmeter (multimeter);

tire pump with pressure gauge;

a piece of hose with clamps of the appropriate diameter.

Check procedure:

Using a screwdriver, disconnect the power wire from the emergency sensor.

Using a 22mm wrench, unscrew it from the fitting (tee).

We connect the pressure gauge fitting to one end of the hose. We fix the connection with a clamp.

We put the other end of the hose on the sensor fitting. We clamp the connection with a clamp.

We connect the probes of an ohmmeter or multimeter turned on in ohmmeter mode to the sensor terminal and its body (ground). The resistance should be zero (contacts closed).

We begin pumping, controlling the pressure and resistance of the sensor. When the pressure reaches 0.4–0.8 atmospheres, the sensor contacts should open and the ohmmeter should show infinite resistance. This means that the sensor is working. Otherwise, it must be replaced.

The principle of testing is to create the pressure inside the sensor necessary to open the contacts

How to reduce fuel consumption

Having figured out what the fuel consumption standards for the Gazelle 405 are and comparing them with the fuel consumption indicators of your car, if you exceed them, you can significantly reduce the amount of fuel consumed per 100 km of run, adhering to just a few rules. You should:

promptly check all systems and components of the Gazelle and carry out their repairs in a timely manner;
use only high-quality fuels and lubricants;
adhere to the basic rules for operating the Gazelle 405 with an injection engine;
if you do not have sufficient experience in servicing injection engines, contact service station specialists;
reduce to a minimum the use of air conditioning, high beams and all other additional devices;
Carry out tuning of the Gazelle after a certain number of kilometers.

GAZ-31105 with ZMZ-402 engine

The base engine for the GAZ-31105, which was transferred to it from the previous model, is a 2.4-liter ZMZ-402 carburetor engine, developing a power of 100 hp. and maximum torque of 183 Nm. Production of Volgas with a carburetor engine was discontinued in 2006 - they were replaced by injection engines of various types.

Gasoline consumption of GAZ-31105 with ZMZ-402 engine per 100 km. Reviews

Maksim. Seversk Volga 31105, carburetor engine ZMZ-402, 100 horses, 2004. Of course, the carb engine is a thing of the past, but at that time there were no normal options with injection engines in our city - they were all dead. And in terms of money, the injectors were more expensive. On the other hand, I have repaired the carbs more than once, so there were no problems - after adjustment, my consumption was 12-13 in the city and 8 liters on the highway, no more.
Timur, Tula. In fact, there is no point in slandering the Volga - the car is quite decent for the money. Its fuel consumption is not that high - in the city from 12 to 15 liters (in winter), on the highway 8-9 liters, no more. But there is a lot of space in it, and it rides quite smoothly.
Peter, Perm. I believe that the Volga is the most successful domestic car. Firstly, it is reliable, and secondly, it is really comfortable, there is plenty of space and it’s convenient. The engine is powerful, and in terms of fuel consumption the situation is not the same as with the 24th and 29th Volgas - my gasoline consumption was 13-14 liters in the city and about 9 liters on the highway, but that’s if you drive quietly.
Alexey, Surgut. If you want to buy a Volga GAZ-31105, then I will give you a couple of tips. First, spare parts are expensive and repairs are expensive, unlike Lada. Secondly, it is difficult to find a normal service. Third - don’t buy the Volga at all, because you won’t sell it. The ZMZ-402 engine is complete crap, the carb always created problems, for such a cow it is rather weak, therefore, there is no dynamics. If you drive like a pensioner, then the consumption is about 13 liters in the city and 9 on the highway, but if you drown it just a little, then the highway is 12 liters, the city is still 15-16 liters.
Daniil, Ivanovo. GAZ-31105, 2004, engine 2.4 l carburetor, 100 hp. It has its pros and cons. Compared to the domestic auto industry of those years, it is one of the best options, at least to sit comfortably in it. Compared to foreign ones, it completely sucks, in its class the car is practically naked, the engine is weak and consumes a lot - 14 liters in the city with a volume of 2.4 liters and no dynamics.

Fuel consumption for different engines

The fuel consumption of Gazelles with different types of engines is insignificant, but still different. As already mentioned, the number of liters consumed is influenced by a number of external factors - unevenness of the road surface, traffic jams, climatic conditions, the use of a large volume of various auxiliary parts inside the car body, and much more.

Various sources of information provide different data on the fuel consumption of the Gazelle 405, injector. With an engine capacity of 2.4 liters, the average fuel consumption varies within eleven liters per hundred kilometers.

But, when using two types of fuel, this figure can be significantly reduced.

The gasoline consumption of the Gazelle ZMZ 405 per 100 km is approximately twelve liters. But this indicator is relative, since it may change under different operating conditions.

Average fuel consumption on the highway is within the stated standards, since here it is possible to adhere to the speed limit. And if your car is not too loaded, and you adhere to all the rules for using additional devices, then you should not worry about significant fuel consumption.

For example, Gazelle business, due to the introduction of more advanced technologies, has reduced fuel consumption by more than five percent. And in a Gazelle car with a Euro engine, due to the increase in engine volume, fuel is consumed even less,

in comparison with other models.

Viscosity selection

First, let's look at the manufacturer's recommendations. Oils with viscosity 10-40, 5-40, 0-40. Probably everyone knows that the first number indirectly indicates the “pumpability” of the product at low temperatures. Pay attention to the second number. It's the same everywhere. The viscosity of 5-30 is not indicated anywhere. I'll try to explain why in a nutshell.

ZMZ engines are very poorly bored. The so-called “group method”. That is, 100 blocks were brought from the boring machine, the pistons are guaranteed to fit into them and the engine should start working. This phenomenon has a pederastic name in our factories - “assembly guarantee”. The gap in the piston-cylinder pair should be on average 6 acres (0.06mm). Four hundred square meters is a clear gap and two or three hundred square meters per hole in the cylinder. The average figure for ZMZ engines is 10 acres. There were specimens up to 15 acres. What am I talking about? Oddly enough about the viscosity of the oil.

Thinner oils for a given engine can be simply destructive. With such gaps, it simply will not stay in the piston-cylinder pair. Therefore, the factory recommends oils of these viscosities. The plant simply provided itself with insurance.

Oil selection

There is no fundamental difference between pouring domestic and imported motor oil into Gazelle 405 engines. Many people believe that foreign lubricants are of higher quality and are significantly ahead of their domestic counterparts in this component.

This is not entirely true. It all depends on the manufacturer. Among imported oils there are truly high-quality solutions with excellent properties and characteristics. And there are also low-grade compounds, pouring which into the Gazelle engine will only harm the engine.

Experts recommend starting from the quality requirements and compliance with classifications provided by the Gazelle 405 automaker.

There are two main criteria here:

domestic service station classification, in this case the selected oil must meet the requirements of B4/D2;
The international API classification is relevant for imported oils.

According to API, the following oils are suitable for Gazelle 405:

If you find a motor lubricant that meets these standards and classifications, half the battle is already done.

It is also important that the oil for the Gazelle meets the temperature conditions in which the car is operated. Most adhere to the principle of choosing all-season oils. Only for certain regions of the country, where the temperature drops below -30 degrees Celsius, it is necessary to use purely winter brands of motor oils.

The most common viscosity solutions for Gazelle 405 are:

10W30;

In the first case, the oil can withstand operation in the temperature range from -30 to +20 degrees Celsius. This is acceptable for some regions of Russia.

Consumables and tools

To change the oil in the Gazelle 405, you will need to assemble a standard set of consumables and tools. Decide for yourself when choosing a lubricant. But there’s no need to save, even though we have an inexpensive domestic Gazelle in front of us.

Most car owners choose Lukoil oil. A brand of lubricant suitable for Gazelle 405 from a domestic manufacturer costs about 1,100 rubles per 5-liter canister. Don't forget to purchase an oil filter.

There are several options for filter elements:

VAZ (costs about 270 rubles and is original for the Gazelle 405),
Big Filter (150 rubles),
Hola SL (190 rubles),
Finwhale (250 rubles),
Mann (200 rubles).

Prices are approximate and may vary depending on the region and store.

Consumables are not very expensive, which makes the Gazelle 405 quite cheap to operate and maintain. In addition to the oil and filter, you need to take:

ratchet with a size 24 head,
special puller for oil filters,
container for draining waste,
funnel for pouring fresh oil,
gloves and safety glasses,
screwdriver
rags.

It is best to work in the presence of a hole, overpass or lift. If there is none of this, then climb under the Gazelle, having first laid some kind of bedding on the floor. The car is quite tall, so working under it is not as difficult as under many passenger cars.
