Increased Fuel Consumption Priora 8 Valve • Winter period

Reasons for discrepancies

...using a caliper we check the distance between the end of the valve needle and the supporting surface of the regulator flange. The distance should be no more than 23 mm. This is necessary in order not to damage the regulator during installation - the regulator needle should not rest against the seat of the throttle assembly. It is necessary to take into account that if the specified distance for the new regulator is more than 23 mm, then it will be possible to retract the locking needle into the regulator only with the help of a special tester (at a service station). Before installing the idle air regulator, clean the valve seat, air duct and surface for the sealing ring in the throttle assembly. Apply a thin layer of engine oil to the new regulator O-ring.

Increased fuel consumption on Kalina 8 valves

The fuel consumption indicated by the manufacturer may differ significantly from the readings observed by the owners of this car. Let's find out what gasoline consumption of the Lada Kalina is indicated in the instruction manual and what real figures are observed by car enthusiasts.

The technical characteristics of Kalina (sedan, station wagon, hatchback or sport) indicate “ Fuel consumption by driving cycle, l/100 km ”:

• for Kalina 1.4l is equal to 7.0;
• for Kalina 1.6l from 7.2 to 7.8.

To determine the real fuel consumption on Kalina 1.4, we analyzed reviews from owners. As a result, it turned out that:

• Consumption in the city ranges from 6.8 l/100 km to 11.5 l/100 km. The average is 8.47 l/100 km.
• Highway consumption ranges from 5l/100km to 8.5l/100km. The average is 6.18 l/100 km.
• The combined cycle ranges from 6.5l/100km to 8.3l/100km. The average is 7.29 l/100 km.

Fuel consumption for Kalina 1.6 will be slightly higher, the average is 9/6.8/8 for city/highway/mixed. Why do some people have high fuel consumption in their Lada Kalina, while others have much less? There may be several reasons, here are the main ones:

• Driving style . The differences in fuel consumption during quiet driving and active driving (with sharp braking and acceleration) can be significant (10-25%).
• Gasoline quality . Gasoline consumption of AI 95 will be less than AI 92 (article).
• Seasonality . Kalina's consumption per 100 km. in winter it will be more due to slippery roads and warming up. The difference with summer will be 1-2 liters.
• Traffic jams . Even a small traffic jam can increase gasoline consumption by 2 liters.
• Air conditioner . When the air conditioner is turned on, Kalina's consumption increases by 0.5-1 liters.
• Kalina malfunctions . If fuel consumption on Kalina has increased significantly, then you should diagnose the car and determine the reasons for the high gasoline consumption.

Driver surveys

To find out what fuel consumption the Priora has per 100 km. it took observations from the drivers themselves, who were already able to verify the real numbers in practice. These reviews are divided into several categories. Of 100 percent of respondents, most of the votes were given for the Priora's fuel consumption of 8-9 liters/100 km.

Further, with slightly fewer votes, we settled on data of 9-10 liters/100 km. The next results were consumption of 7-8 liters, which was voted for by one third of the drivers, the majority of those participating in the survey. Also, in the minority of votes, there were reviews (from large votes to small ones):

• 12 liters/100 km;
• 10-11 liters/100 km;
• 11-12 liters/100 km.

Ways to eliminate the “sore”: The engine overheats

1. Engine size (Lada Kalina comes in two types - 1.4 l and 1.6 l).
2. Number of valves (for Lada Kalina - 8 and 16).

What is the real fuel consumption of the Lada Kalina per 100 km • To visually assess the consumption, you should monitor the current indicator in 4th, 5th gear during quiet driving.

Prevention Techniques

High gasoline consumption on a Priora can be normalized using logic and common sense. After checking the systems, the specialist must correct the deficiencies, if any. Or, having ruled out problems of this nature, master driving techniques that will prevent overspending:

1. It is necessary to monitor the tire pressure and avoid serious deviations from the 2.0 atm mark. This can be done at gas stations, using purchased equipment at home, or at other special points.
2. It is necessary to ensure that the windows are closed while driving, and also to remove the roof rack, if there is one. It’s not difficult to do, and the car’s consumption will decrease.
3. Review your driving style: take care to change speed smoothly, do not change it unnecessarily.
4. Use engine braking.
5. If the engine has not reached the desired temperature, it is important to warm it up; this can be done while moving.
6. Do not fill the car with gasoline other than 95.
7. When traveling, turn off climate control systems.

If you follow these recommendations, the fuel consumption of the Lada Priora will decrease significantly. You can additionally consult with a professional, since the combustion of “extra” fuel significantly affects the financial situation of the owner. There is reason to seriously work on this issue.

For your information

• When estimating the actual amount of fuel consumption, it is advisable to follow the generally accepted method: fill the tank full, reset the odometer, drive a certain number of km and fill the tank full again, while simultaneously noting the amount of liquid filled. The required value is found by dividing liters by kilometers traveled.
• The on-board computer in mixed mode, after resetting, starts counting from 19.9 l/100 km.
• To visually assess consumption, you should “monitor” the current indicator in 4th and 5th gears during quiet driving.

Total

The factory fuel consumption figure for Priora with 16-valve engines is 6.6-6.9 liters per mixed “hundred”. In reality, the appetite ranges from 8 to 14 liters. in winter and 5.5-11 l. in summer.

It's an environmentally responsible thing to do and will indirectly help save fuel. We believe that cars require no maintenance other than worn brake pads, tires, shock absorbers and filters. However, as high-energy ignition systems move away to the cross electrodes, the gap becomes wider and the spark is less consistent and intense. Get yourself a fresh set of spark plugs for better gas mileage. And while you're at it, check your ignition coils and wiring harness.

Vacuum leaks are easily one of the most overlooked faults because we tend to assume the worst and miss stray suction entirely. Vacuum leaks often prevent detection. Since so many under-hood jobs rely on intake manifold vacuum, there are apparently miles and miles of vacuum hoses from bumper to bumper. Vacuum hoses are dry, as are tees and other connections. And when they do, they create vacuum leaks that can disrupt the electronic engine management system.

Increased fuel consumption can be caused by malfunctions in the fuel system, in the ECM, a clogged air filter, a clogged catalyst, incorrect operation of the air purge valve, or air leaks. Tire pressure and driving style also determine energy consumption.

Real reviews from owners about fuel consumption on the Lada Priora:

You get rough or unusually high idle and less power. The result is poor fuel economy. Fuel pressure regulators are typically flight vehicle components, but they can fail. A faulty fuel pressure regulator may or may not cause too much fuel pressure. Too much means high fuel consumption and poor performance.

14: Ignition coils and seat belts

However, high-energy ignition systems and sizzling temperatures take their toll on ignition components. Coil-based ignition systems virtually eliminate ignition wires. However, many traditional coil and distributor ignition systems remain. When you change spark plugs, try checking and, if necessary, replacing the ignition wires and coils while you're at it. This keeps the entire ignition system fresh and in addition to the ignition business.

• I am a measured driver, so the “acceleration-deceleration” mode is not for me. Fuel consumption is interesting for sporting reasons. It suits me along with the car. In fact, during the run (see above), fuel consumption per 100 km never exceeded 8 liters in mixed mode.

• A – voltage 12V.
• B – “–” (mass).
• C – “–” reverse earth (literal translation).
• D – output signal SIG to the ECU.

What other factors influence

Engine operation itself affects Priora's fuel consumption, and various manipulations force the injectors to inject more mixture into the cylinders. This occurs when switching the gearbox selector, sharp braking or accelerating, as well as during frequent turns of the ignition key.

The next most important factor why fuel consumption on the Priora has increased is the air conditioning, especially if it is operating at full capacity. If it is necessary to influence the climate, it is not recommended to turn on the maximum to quickly achieve results. It's better to do it gradually.

An unheated engine increases the fuel consumption of the Priora. Therefore, it is important to ensure that it reaches the optimal temperature. Approximately the same effect is exerted by headlights while traveling, insufficient tire pressure and open windows (noticeable at speeds of 55 km/h).

Engines and official fuel consumption rates for Lada Priora

Popular among domestic car enthusiasts, the Lada Priora is equipped with a line of gasoline engines developed by the VAZ concern. They have proven themselves to be reliable and maintainable units. The following motors are installed on the car:

1. 1.6 at 90 forces:
2. 1.6 at 98 forces;
3. 1.6 at 106 forces;
4. 1.8 at 123 or 130 forces.

An important feature is that the fuel consumption of the Lada Priora does not exceed that of the leaders of its class. Given the relative cheapness of the car, this attracts additional attention from potential buyers. Priora has mechanical and, since 2014, automatic transmissions.

VAZ-2112 owner reviews about consumption Theoretical indicators

First of all, the ability to achieve low consumption of a high-octane composition is determined by the serviceability of all vehicle systems. A massive power plant, in order to obtain results in speed or power, consumes less gasoline than a similar car with a smaller engine.

Reasons for discrepancies

Among other things, urban driving style will vary greatly depending on the congestion of the roads on which the car is driven, the duration of the trip, warm-up time, and the length of time it is parked with the engine running. Well, before concluding the article, I would like to say that fuel consumption in winter is affected not only by engine idling, but also by a bunch of other parameters.

Lada Priora 1.6 MT 98 hp

Features of the package

Another power unit from the line of engines of the basic Lada Priora is the same four-cylinder unit with a volume of 1.6 liters. Its significant differences are that the number of valves has been doubled - now there are 16. In turn, this has affected the increase in power from 90 to 98 horsepower. The maximum speed of a car with such a unit installed under the hood is 183 km/h, while acceleration to hundreds of kilometers will take 11.5 seconds, which is one and a half seconds faster than 90 horsepower. Fuel consumption in the urban cycle has also increased - so, now 9.8 liters are spent per 100 km, and 5.6 liters on the highway.

Owner reviews about consumption

• Pavel, Astrakhan. Before this Priora, I drove the ninth VAZ model for a long time. I decided to take something newer and inexpensive. The car (I took a used one from 2007 with 97 thousand mileage) is very good, even because I, a tall person, can sit in it comfortably. The interior is not noisy, but its build quality leaves much to be desired. Yes, and the gears are difficult to switch, especially 3rd. Consumption on average is 7.5-8 liters.
• Maxim, Tambov. Lada Priora 1.6 MT 2008. The car is new and I recently purchased it. So it’s too early to talk about the pros and cons. But the first thing that caught my eye was the good design and engine. Its consumption per hundred is about 8 liters. Among the shortcomings, I noticed that the trunk lid was knocking and there was a strong creaking noise in the cabin. I'm guessing it comes from the brakes.
• Ramil, Belgorod. I drive relatively recently, I bought a 2009 car second-hand. First impressions are good. The only thing is that the engine makes too much noise, and the doors have poor sound insulation. On a dirt road, the car jumps a lot, apparently due to the harsh suspension. Consumption in the city is 9-10 liters, on the highway 6-7 liters. Overall happy with the car.
• Denis, St. Petersburg. Priora 1.6 MT 2008. Of course, for that kind of money they could have tried to make a better car. The first serious problem I encountered was that after 9,000 km the heating system stopped working. In addition, it was possible to install air conditioning in cheaper trim levels. Consumption at the moment the computer shows 7 liters per 100 km.
• Andrey, Chelyabinsk. Our people still don’t know how to make cars. Over a period of 100 thousand km, I changed the steering rack twice. I repaired the box because it started to lose the first two speeds. The interior is put together disgustingly - all the control buttons are already sunken, just like the seats. The only normal thing is consumption - 7-8 liters per 100 km. It's time to switch to a foreign car.

#1 Andruchka: Fuel pump and filter

Get ready to fork out money if you use incorrectly selected oils, which, with increased viscosity, increase gasoline consumption for the Priora by 15. Unstable or reduced pressure in the fuel system, which prompts you to check the cleanliness of the filters, the service life of the fuel pump, and the free passages of the injectors.

Increased fuel consumption on Lada Priora: why? • Winter period

1. The serviceability of the engine, as well as all systems that relate to fuel consumption (stove, air conditioning, etc.);
2. Engine capacity;
3. Ambient temperature;
4. Number of included energy consumers (“air conditioner”, stove, headlights, radio, etc.);
5. Fuel quality. If, for example, you fill in 92 instead of 95, then be prepared for the consumption to increase. In addition, if the fuel is of low quality, then its consumption will be higher by about 15-20%, depending on the “degree of lousiness”.

Car color

Some motorists argue that the cost may directly depend on the color of the car. For example, a light model consumes much less than its dark counterpart, but this is far from a guarantee.

American scientists have proven the influence of color. They found that this manifests itself especially in the warm season.

When the car heats up, it spends a lot of energy cooling the interior and, of course, fuel consumption increases

In the interiors of dark cars, during the hot season, the temperature was several degrees higher than in light models. That is, the fuel consumption of the Priora station wagon (per hundred) in the summer will be less.

It's a difficult time of year for cars. Priora fuel consumption can vary significantly. The 16 valve Priora consumes more in winter. Firstly, when the engine is not warmed up, the gasoline consumption of the Lada Priora will be higher.

Secondly, the increased complexity of roads that require the car to drift also increases fuel consumption. Thirdly, speed. The slower the car moves, the more gasoline it uses.

Lada Priora, which has 16 valves, is overall more economical than other cars with similar technical characteristics. In addition, if you wish, you can always convert it to gas consumption and significantly save your family budget.

#1 Andruchka

Experts, please tell me a potential reason for the increased fuel consumption.

The engine is a standard one. In the city, the on-board computer began to show 18 liters per hundred; when accelerating, the car picks up speed “thoughtfully”, with failure and delay. Could this be related to the TPS or the MAF? And what, in general, could be the reasons for the sharp increase in fuel consumption on the Priora (all other things being equal).

Surely this topic has already been discussed more than once before, but I couldn’t find anything by searching. And in general, I haven’t been here for a long time - everything has changed so much.

Thank you very much for your help in finding the cause of the problem.
