Specifications


Diesel 3309 can be of several types depending on the type of body: chassis, flatbed cargo platform, all-metal body, trailer with body.

New product "Dobrynya"

The new one is a modification of the 3309 model. The Dobrynya truck, whose carrying capacity is of average value, is in great demand for the transportation of various goods. Price for supported models 2006-2008 the issue ranges from 400-600 thousand rubles.

It looks like a truck Dobrynya GAZ 3309


The manufacturer has developed a new GAZ cab, in which a sleeping bag is provided. Metal is used for its manufacture. The sleeping bag is sheathed on 4 sides with sheet steel. Inside the bed is finished with fiberboard and foam. The latter material gives the sleeping area warmth and soundproofing. In this compartment of the cab there are 2 fold-down shelves, under which there is a luggage compartment.

For external treatment of the sleeping bag, the manufacturer uses thermal powder paint. This treatment protects the cab from corrosion. Sleeping bag length - 2.15 m. A van can be installed if necessary. The difference between the new cab and the old one:


The new cab is made of fiberglass, which increases the durability of the structure. The cab doors remained unchanged. A new plastic bumper is installed at the front of the body. The structure is fixed with a rigid frame. Cab roof spoiler saves by improving dynamic characteristics car.

If necessary, a 5.2 m long van can be installed on a new truck. The carrying capacity of such a model increases several times, and the volume reaches 26 m³. The van can have a manufactured goods or isothermal purpose.

Technical equipment

The carrying capacity of the Dobrynya vehicle does not exceed 4 tons. Experts refer to the main technical characteristics of this truck:

  • rear drive;
  • diesel engine (D-245) with a turbine;
  • engine power 125 hp sec., and the working volume is 4.75 liters.

The power unit complies with the Euro-4 ecology class. An in-line arrangement of four cylinders is observed. The diesel engine has the following additional characteristics:

  • compression ratio - 17.0;
  • maximum torque value - 42.5 kgf (1100-2100 rpm);
  • weight - 430 kg;
  • liquid cooling.

If the truck is equipped with a van, then its frame, unlike the model with a cab and a sleeping bag, is lengthened by 0.8 m. The insulated van is trimmed with galvanized sheets inside.

Technical characteristics of the truck Dobrynya GAZ 3309


In the body of the vehicle, a plafond of illumination is provided. The cockpit of this Dobrynya model has 2 seats - a driver's and a passenger's. The driver's seat is equipped with a link suspension, which dampens vibrations when the vehicle is moving. There is a hatch on the roof of the cab, and a shelf for storing things inside the structure. The new GAZelle is equipped with an anti-lock braking system, a volumetric tank.

Pros of the novelty

The manufacturer of the "Chaika-Service" model has developed a new generation truck. "Dobrynya" has an original appearance and new technical capabilities, which made it possible to bring the GAZelle to high level... The updated GAZ-309 has the following advantages:


Common features

GAZ-3309 and the novelty "Dobrynya" consume an average of 14-16 liters. With. when driving at a speed of 60 km / h. This indicator depends on the following factors:

  • type of power unit;
  • the quality of the fuel used;
  • loading the truck;
  • movement speed;
  • weather conditions;
  • the condition of the road surface.

The fuel consumption value depends on the equipment of the engine. The power reserve is not more than 750 km. With an increase in speed by 20 km / h, the consumption increases by 4-6 liters. Some GAZelle owners believe that the fuel consumption values ​​declared by the manufacturer differ from the actual fuel consumption. But the drivers themselves are to blame for this. The manufacturer explains it this way: the operation of the power unit depends on the quality of the diesel fuel used.


Driving style has a significant impact on this indicator. Often old and new machines are operated at maximum utilization. The above factors contribute to the rapid wear of many mechanisms, which degrades the performance of the power unit. This increases fuel consumption. Experts attribute the possibility of self-tuning to the advantages of the old and new models.

Domestic trucks of the Gorky Automobile Plant have been popular since Soviet period... As you know, engine oils, and GAZ are no exception, must have high adhesion properties and reliably protect the main mechanisms of the system from corrosion corrosion, effectively remove heat from the rubbing surfaces of parts and prevent wear.

General characteristics of oil for GAS

According to the operational conditions for the functioning of the internal combustion engine: pressure, temperature indicators, the strength of the frictional interaction of parts, as well as the material of their manufacture, various types of motor oils are used on GAZ cars.

They have one thing in common: high-quality greases should not change their original characteristics during operation or under the influence of temperature fluctuations.

At the same time, they must comply with the vehicle manufacturer's requirements and general approval. The composition should not contain harmful waste and impurities, alkalis and acids. A lubricant component with a certain level of viscosity, temperature setting and stability is used for each engine separately.

With regard to viscosity, this indicator demonstrates the resistance of particles to mutual movement. If the oil has a high degree of viscosity, then it is difficult enough to penetrate into the engine and poorly sprayed.

Accordingly, if this parameter is not observed, the car oil negatively affects the reduction of friction of parts, which leads to rapid engine wear. Viscosity is usually denoted by numbers in front of the letter indicating the brand. Thus, the higher the index, the greater the degree of viscosity.

As for stability, this means its ability not to change its original properties for a long time. This is an extremely important factor for the operation of GAZ vehicles. Solidification of a lubricant denotes its temperature at which it loses its mobility properties.

Lubricating products for GAZ power units are designated by numbers and letter symbols. The number is the degree of viscosity, the letter M and subsequent numbers indicate the performance.

Oil for GAZ 53

In the internal combustion engine 53 models, off-season greases AC8 or M8B are usually used. The first marking is an older version of the oils designation. The letter A indicated engines with carburetors, C was the cleaning method, and the last figure indicated the degree of viscosity of the fluid.

For the most efficient operation of the oil, it is recommended to use special additives in the GAZ engine. They increase the viscosity of the base lubricant and also prevent strong fluidity and improve system performance. For GAZ, complex additives are usually used that change some of the properties of a car oil.

Lubricant for the GAZ 3110 engine

For the 3110 internal combustion engine with 8 cylinders, it is necessary to use a natural oil with a viscosity level of 15w30, 10w30. Also recommended for use are semi-synthetics with a viscosity of 10w40 from the companies Gazpromneft, Lukoil.

If the vehicle is actively operated in severe frosts, then it is necessary to fill in synthetic products with a viscosity level of 5w40. However, for such engines, it is best to use lubricants based on mineral and semi-synthetic bases.

As for the volume of motor oil, for the GAZ 3110 engine system it is necessary to use about 8 liters, and in old 3.5 engines - no more than 7 liters. The lubrication change frequency is carried out upon reaching 5000-7000 km, according to the operating conditions.

Engine oil GAZ 3307

For power units with 8 cylinders on a gasoline basis, it is recommended to use engine fluids with a viscosity level of 10w40 and 5w40 on a semi-synthetic basis. You can also fill in mineral water with a viscosity of 20w50, 15w40. Factory oils have been specially developed for model 3107:

  • Master 10w40;
  • Professional 5w40;
  • Mineral oil Original and Standard.

Any factory lubricants can be changed to alternative foreign options. For filling, 10 liters are required. Replacements are carried out upon reaching 7,000-10,000 km of run in accordance with the operating conditions.

For engines on a diesel basis with volumes of 4.75 and 4.43 liters, it is necessary to use about 12 liters of grease. It is recommended to use liquids on a mineral or semi-synthetic base as a filling. The viscosity is 15w40, 5w40, 10w40. Replacement frequency - upon reaching 7,000-10,000 km of run.

If there is a desire or need to replace the factory oil with identical analogs, then you can use any mineral formulations. Experienced car enthusiasts recommend using motor lubricants from manufacturers:

  • Lukoil;
  • Gazpromneft;
  • Castrol;
  • Shell.

The main thing is not to forget that the product must correspond to the level of viscosity, depending on the operation of the car for certain weather conditions.

For the Volga power units of the first generation of 1968, off-season mineral-based fluids with a viscosity level of 15w20 and SG quality are relevant. If we are talking about newer vehicle trim levels, then for the cold season it is recommended to fill in mineral water 5w20 SG.

Any selected car oil must be checked against the factory requirements and specifications for the GAZ 21, as well as the maintenance intervals. Mainly 21 model owners use semi-synthetic oils with a viscosity level of 10w40. They work great at any time of the year.

For replacement, about 6 liters are used. In summer, it is recommended to use mineral greases with a change interval of 7-10,000 km. As for the brand, it is worth giving preference to the above options.

Oils for GAZ in winter

Thanks to the marking, each GAZ owner can choose the most optimal oil for his car model. In winter, the lubricant must be selected according to temperature indicators and viscosity characteristics. Ideally, these are formulations with viscosities from 0w30 to 10w40.

0w30 is less viscous, but even in severe frosts -30 / -40 it does not lose its original flow properties and interacts perfectly with internal combustion engines.

As for oils with an indicator of 5w30, they are also used in winter, when there are light frosts. Oils with index 10w30 are recommended for use in regions with milder weather conditions.

The 10w40 mark demonstrates versatility. That is, the lubricating fluid can be used in areas where temperatures are observed down to -5 ° C.

Do not forget the fact that a lower indicator demonstrates the level of viscosity during the heating period of the engine and its further reaching operating temperatures. If the oil has too much fluidity, then it will not be able to guarantee full protection of the GAZ engine in comparison with thicker lubricants.

In other words, we can say that with high fluidity, a thinner, not so reliable film is formed to protect the main mechanisms of the GAZ system. Accordingly, in order to be sure of the instant start of a cold unit, it is best to use lubricants with a viscosity level of 5w30, 5w40, 15w30.

Taking into account the peculiarities of operating a GAZ car, it is necessary to follow the manufacturer's recommendations and fill in better quality products in accordance with the climatic zone.

For example, if in technical instruction it is indicated that for a specific car model it is necessary to use 10w40 or 5w30 oils, then it is necessary to select fluids taking into account the possible lowering of the temperature conditions of a particular region.
