When buying a car, the owner is interested in the question of fuel consumption. The fuel consumption of the VAZ 2112 16 in comparison with other models of this car brand is considered economical and acceptable. But it is worth considering that even the driver depends on gasoline consumption for a certain distance. To understand this issue in more detail, it is necessary to consider all the reasons and nuances that affect the decrease or increase in fuel consumption. The actual fuel consumption of the Lada 2112 in the city is approximately 8 liters per 100 kilometers.
If your car's engine uses more fuel, then you need to find out all the direct factors that influence this.
Average fuel consumption values for VAZ 2112
When purchasing a car, you must immediately know the average fuel consumption of the engine under three main conditions.
| Engine | Consumption (highway) | Consumption (city) | Consumption (mixed cycle) |
| 1.5 5-mech | 5.5 l/100 km | 9.1 l/100 km | 7.6 l/100 km |
| 1.6 5-mech | 6 l/100 km | 10 l/100 km | 7.5 l/100 km |
| 1.5i 5-mech | 5.5 l/100 km | 8.8 l/100 km | 7.2 l/100 km |
The first is the fuel consumption of the VAZ 2112 on the highway, which averages from 9 to 10 liters. In rural areas, off-road - from 9.5 liters. In a combined cycle, fuel consumption on a VAZ 2112 should be at least 7.7 liters. If your VAZ car requires much more, then you should pay attention to the following points:
- like driving style;
- engine's type;
- car mileage;
- specifications;
- fuel quality.
Driving maneuverabilityVAZ
The first thing auto mechanics advise you to pay attention to when fuel consumption is high is your driving style. Lada is a car that does not tolerate slow acceleration or slow acceleration.
The gasoline consumption of a VAZ 2112 per 100 km in the city will be up to 7.5 liters, only when the car drives smoothly, without jerking, switching to different speeds, and also choosing the optimal driving style in summer and winter.
Keep in mind that in winter up to 1 liter is needed to warm up the car. If you do not do this, then the engine will require a lot more gasoline when driving to warm up the system while driving.
Engine type VAZ
The 2112 hatchback has a 1.6-liter fuel-injected engine with 16 valves. A 5-speed manual transmission is installed. For such an engine, the fuel consumption of the VAZ 2112 (16 valves) is an average of 7.7 liters.
As for the engine type. If the VAZ 2112 fuel consumption per 100 km exceeds 8 liters, then you need to pay attention:
- fuel filter;
- valve filter;
- nozzles;
- candles;
- valve;
- oxygen sensor.
You should also check the condition and adjustment of the electronics and its reliability.
Characteristics of VAZ-2112
The VAZ-2112 car was positioned by the plant as a model with increased dynamic characteristics; initially, the cars used in-line 4-cylinder power units with fuel injection (carburetor versions were not offered). The equipment was equipped with 5-speed manual transmissions with front-wheel drive (the gear ratio of the main pair depends on the engine model). The all-metal body (shortened compared to the sedan) is designed for a driver and 4 passengers, the luggage compartment is closed with a lift-up lid.
The car is equipped with a rear sofa with a separate backrest and a folding mechanism, unified with the seat from the station wagon. The shortened luggage compartment has a positive effect on the handling of the hatchback, which reacts sharply to steering wheel deviation.
The hydraulic brake system with a vacuum booster remains unchanged (discs are installed at the front, drum mechanisms are used at the rear). The VAZ plant mass-produced the car from 1998 to 2008, abandoning further production in Ukraine under the Bogdan brand.
The cars were equipped with rack and pinion steering without hydraulic power steering. The standard equipment included a cabin ventilation unit with a heating radiator, and a small number of cars were equipped with air conditioning. Basic versions had manual window drives in the front doors; on expensive versions, electric windows were offered. The car had a low level of passive safety; the design was not designed to install airbags or an anti-lock braking system in the brake drive.
3-door VAZ-2112
Since 2002, the 3-door Lada-21123 coupe, based on the body of the 2112 car, has been produced in small series since 2002. The cars used only 16-valve engines with a volume of 1.6 or 1.8 liters; according to the main technical parameters, models with 3 and 5 doors were no different.
The coupe had a body with increased torsional rigidity, which further improved handling. Assembly of the model ceased in 2009.
Car mileage
A very important point is the mileage of the car, as well as its condition. If this is a new car from a showroom, then all average fuel consumption indicators should match. If the car’s mileage has exceeded 100 thousand kilometers, then gasoline consumption may exceed the average.
It also depends on where the car was driven, on what roads, at what pace, and whether the engine was repaired. To find out exactly what gasoline consumption on a VAZ 2112 will be under your driving mode, fill the tank with 1 liter and check how far you can drive. Car mileage is the total number of kilometers that the car has traveled without repairing the engine and its main components.
Machine Specifications
A Russian passenger car with a hatchback body with easy maneuverability, it has fairly good factory technical characteristics. In order for fuel consumption to remain constant and not increase, it is necessary to monitor the technical characteristics of the entire vehicle. Inspection at service stations, as well as computer diagnostics will help you with this.
Fuel quality
The fuel consumption at idle speed of the VAZ 2112 is affected by the quality of gasoline, as well as the ketone number of the liquid being refilled. An experienced driver can safely say that he noticed how fuel consumption changed not depending on driving style
, not from the engine or even from the filters, but from high-quality fuel. When driving a VAZ 2112, you should take into account its mileage, as well as what you put in the tank. Accordingly, the amount of fuel consumption is determined from this.
Installing a 16-valve engine on
Why is it necessary to install a 16-valve engine on a “classic”? And is the game worth the candle? A definite answer can only be given if we analyze all the advantages and disadvantages of such a modification. First, you need to consider what the engines of the classic series and more modern ones, for example, installed on the VAZ-2112, are. Some difficulties may arise during the work, but they can be overcome if you approach the matter with a clear head.
For most people, tuning means attaching plastic body kits and stickers to the car body. There was even such a concept as “collective farm tuning”.
This phrase describes cars that have difficulty moving on the roads, but are covered from roof to wheels with stickers with emblems of some brands.
It is much more pleasant when a simple car that does not stand out from the crowd has technical characteristics comparable to foreign-made vehicles, and not of the lowest class.
Why is it necessary to install a 16-valve engine on a “classic”?
Classic series cars have not been produced for many years, but spare parts for them are still available for sale. Pay attention to the engine - there are only eight valves, there are just over seventy “horses” in the harness, and the timing chain makes eerie sounds, increasing the noise level. You can increase the power and acceleration of your car in several ways:
- Changing the fuel system (transition from an obsolete carburetor to an injection system).
- Replacing the engine with a more advanced model.
- In the case of fuel-injected cars, changing the ECU firmware can help (fuel consumption increases in proportion to power).
It is worth considering the second option in more detail. If you have a car with a carburetor engine, then you kill two birds with one stone - install a new engine and completely change the fuel system. It is worth mentioning that the ignition system is also being transformed - instead of a contactless one, you will need to install a microprocessor one. And hence the increase in reliability, power, and durability of the power unit.
Is such a replacement legal?
Recently, there has been a law according to which a car engine does not require mandatory registration. In fact, the engine of a “classic” becomes an ordinary spare part, like a bumper or thermostat.
But you need to adhere to the recommendations that come from experts. When purchasing a motor, enter into a sales contract. If possible, check the traffic police database for the car from which the power unit was removed.
The seller must provide you with documents that confirm his absolute right to own the car or engine.
Provided the transaction is clean, there will be no claims against you. You can proceed to the next step after installing the 16-valve engine on the “classic”. This is registration with the traffic police.
Many people have an ambivalent attitude towards the procedure, since some try to formalize the alteration so that everything is official, while others take advantage of the fact that no inspector has the right to inspect the engine, and cannot demand that the hood be opened either.
Even during the state inspection, they don’t pay much attention to such alterations.
What advantages and disadvantages are expected from installing a new motor?
The most important thing is that you will increase the power and response of your car. Installing the 2112 engine in a “classic” gives another advantage - quiet operation. Due to the fact that a rubber belt is used instead of a timing chain, the noise level is reduced. Speed also increases.
The reliability of many units in modern engines is much higher. From an environmental perspective, you will reduce the amount of carbon dioxide released into the environment. This is realized by introducing a catalyst, the operation of which is controlled by two lambda probes.
The disadvantages include the need to rework almost all car systems:
Brake. Electrical equipment. Fuel. Ignition. Clutch.
If you are offered a motor without attachments, then it is better to refuse it, since it will be expensive to buy everything separately. The new 16-valve engine, the price of which is in the range of 60-80 thousand rubles, is beyond the means of most. Therefore, it is better to use the services of the secondary market, where the cost of the motor ranges from 20 to 30 thousand rubles. Moreover, they usually sell not only the engine, but also all attachments, including the ECU and fuel system elements.
Why do you need to redo car systems?
It is worth remembering that installing the 2112 engine in a “classic” entails many changes. And not only in design, but also in technical characteristics. Speed, power and torque increase. And the standard brake system is designed to work with an old motor.
And it may not be able to cope with the loads that will appear after changing the design of the car. Mounting the engine takes little time - just screw it with three bolts to the gearbox.
But its correct connection, configuration, adaptation of systems to new characteristics is a whole science.
Without certain knowledge of the design of the car and its components, you should not even attempt a modification. The brakes on the “classic” should be replaced, even ventilated discs can be used for more efficient operation. It is also better to use disc brakes on the rear wheels.
It’s better to forget about drums, whose efficiency is not always good. The clutch unit works under greater loads than before, so it is recommended to use reinforced models. And don't forget about the crosspieces mounted on the cardan.
It is advisable to replace them with more reliable ones made of high-quality metal.
How to regulate fuel consumption on a VAZ 2112
We have already considered the factors and reasons that affect the use of gasoline in the VAZ 2112. Now you need to know what needs to be done to prevent gasoline consumption from increasing or how to reduce it. The main points to prevent increased fuel consumption are:
- constantly change the fuel filter;
- monitor the operation of the engine system;
- change candles that become black and oily over the years - non-functional;
- watch the condition of the fuel pump mesh so that it does not fall into the glass;
- The catalyst and exhaust must function.
By adhering to these rules, you can save on fuel costs for the VAZ 2112 by 7.5 liters.
Basic rules for reducing gasoline consumption
An attentive driver must constantly monitor all indicators of the car. Monitor the oil level, monitor engine operation, and monitor all filters and strainers. If you bought a car that has already traveled a certain number of kilometers and its fuel consumption exceeds 10 liters, then you should immediately take the following actions:
- change oil (adjust level);
- replace the filter;
- check the quality of gasoline;
- observe the performance of the fuel pump;
- regulate driving maneuverability.
If all this does not lead to the desired result, then you need to do computer diagnostics of the car.
VAZ-2112 – what should be normal fuel consumption?
In order to find out how much gasoline the “twelfth” consumes per hundred kilometers, you should refer to its passport data. The manufacturer, in particular, gives an average figure of 7.5 liters per hundred. However, a car's fuel consumption depends on many factors. For example, the Volzhsky Automobile Plant installed three types of engines on the “twelfth”:
- 21121 – 1.5-liter, 80 horsepower, 8 valves;
- 21124;
- 21120.
The last two engines are 16-valve. The volume of 21124 is 1.6 liters with a power of 89 horsepower. It should be noted that here, if the timing belt breaks, the valves do not bend. Finally, 21120 is a 1.5-liter engine with 93 horsepower.
It should be noted that the consumption of each of these engines also depends on the brand of fuel. For example, when driving an AI-92, this figure is 9.12 liters per 100 kilometers. By filling the tank with higher octane fuel, you reduce its consumption. In particular, with AI-95 gasoline, consumption is reduced to 7.4 liters. An even more noticeable effect in terms of savings is noticeable on premium varieties. In particular, by filling AI-95 Premium gasoline, you will reduce fuel consumption to 6.5 liters. All data is given for the “mixed cycle” mode.
It should be noted that it makes no sense to cite the figures announced by the manufacturer. Real consumption always differs greatly from the passport data. Also, do not forget that driving in urban conditions with heavy traffic significantly increases gasoline consumption. At the same time, on a suburban highway you can travel most of the way in 5th, direct gear. Accordingly, the appetite of the iron horse is significantly reduced.
Fuel consumption differs in winter and summer. In the first case, you often have to fight your way through snowy streets in 1st and 2nd gears. In addition, until the coolant temperature rises to operating temperature, the engine will operate at higher speeds. All this also does not contribute to savings.
A very important point is driving style. With an aggressive style, with sharp acceleration and frequent braking, fuel consumption increases quite seriously. Therefore, if you do not want to overpay for each kilometer of travel, it is better to move more smoothly without revving the engine. Don't get too carried away when pressing on the gas. The most optimal mode in terms of fuel consumption is 5th gear at a speed of 90-100 kilometers per hour.
It should also be noted that fuel consumption can increase significantly due to technical problems. There could be a great many reasons for this. If you find yourself in such a situation and intend to independently find and eliminate the reason for the sudden increase in gasoline consumption by your car, then follow the rule “from simple to complex.” First of all, it is recommended to check the fuel filter. Often it is its clogging that leads to an increase in appetite. Don't forget that it needs to be changed at regular intervals. Consumption may also increase due to dirt getting into the injectors. In this case, you most likely cannot do without a visit to a car service center. It is not recommended to clean injectors yourself if you have never done this before. Believe me, it’s better to pay professionals for the work here.
Pay attention to the fuel pump mesh - it may well become clogged due to low-quality fuel. Also, when identifying the cause of the increased consumption, you will need to check the performance of a number of sensors - idle speed, speed, camshaft, and so on.
Keep an eye on the numbers on the on-board computer - you will often see a prompt with an error code there. Also carefully inspect the spark plugs for carbon deposits and ensure the integrity of the high-voltage wires. By the way, a clogged air filter may well lead to an increase in consumption. As you can see, there are really many reasons, and we have not listed all of them, but only the most common ones.
Well, in conclusion, I would like to give some advice on how to prevent gasoline consumption from going beyond normal limits. Firstly, always carefully monitor the technical condition of the car. Secondly, try to keep your eating style as smooth as possible. Thirdly, do not try to save money by refueling at dubious gas stations - the consequences can be very serious.
