The F14D3 engine, which is installed on the Chevrolet Lacetti, was designed in the early 2000s. True, "designed" - said loud. Almost this is the engine of the company Opel 1996 development X14CH, almost all parts are interchangeable, the nominal and parameters of the crank-connecting-connecting group are identical, but no one really advertises. Well, God with him, us, owners of Lacetti, more concerns the issue of the cost of operation - how to fill in and whether it is possible to go with AI 95 to AI 92.
Lacetti engine is able to digest 92 gasoline, but it is better to pour 95.
Regular Motor Gasoline, so on the international European classification is called 92nd gasoline.
This means that it is used for medium-warning atmospheric engines with an average compression degree. In Europe, they produce both eaten varieties and non-determined varieties of 92th gasoline. At the same time, the 95th gasoline is classified as Premium Motor Gasoline. . How big is the difference between these two stamps? It is enough to ensure that General Motors recommends that AI-95 according to GOST 51105-97 (gasoline eaten).
Figures that are marked by gasoline is octane number. Consequently, three units of difference play a significant role. Moreover, until 2009, GM recommended that gasoline refuel not lower than the 92nd. From that time, the engine was slightly upgraded and the requirements for fuel changed. There are new technologies for the production of petroleum products.
Thus, AI-95 is indeed obtained from low-grade gasolines, but with the addition of modern additives (aromatic components, gasolines, high-temperature distillate processing products). And this is not the same 95th, which we sold more than about 10-15 years ago.
What gasoline to refill in Chevrolet Lacetti
While the car is on warranty service, the tank is categorically forbidden to cast gasoline with an octane number less than 95.
And this is not a capris GM and not an universal conspiracy. If there will be a breakdown during the warranty period and as a result of the examination it will be found that detonation occurred in the engine due to the wrong gasoline brand, the case will be considered non-warranty and pay for the repair of the car. The main reason for the persistent recommendations of the company - prevention of detonation.
Sensor detonation and 92 gasoline
Many people think that the detonation sensor, which is designed to supply the signal about the start of the detonation process to the control unit, the ECU will adjust the magnitude of the ignition.
Yes, it will adjust, but at certain limits. The thing is that the constant correction of the ignition advance angle already suggests that the detonation bursts in the engine were already as quickly reacting the sensor, how quickly the ECU will react and in what limits, it remains only to guess.
And the detonation in the meantime continues. No one needs to explain how much it is destructive for the motor But we saved a couple of rubles at the octane number of gasoline.
Interview
And what is the result: AI-92 or AI-95?
In Europe, by the way there is no 92 gasoline, there is 91. And the difference between it and 95 are even more.
It remains several important conclusions before choosing one of the pistols at the dressing - with 92nd and 95th gasoline:
conclusions
Naturally, everyone can draw conclusions for themselves. However, if we want our lacetta to makeballe more than one hundred thousand kilometers, you should adhere to the manufacturer's recommendations. He does not advise bad. Do not save on oils and gasoline and even all the roads!
How to translate lacetta by 92 gasoline or, on the contrary, at 95? Very simple. Here is a photo and video instruction of this not complicated procedure.
In the world of car enthusiasts, probably the most inexhaustible and contradictory the topic for disputes is what gasoline to use? 92th or 95th?
Even in our community at the time of writing this article, the voices were divided almost equally equally - 52% for the 95th and 48% for the 92nd.
And to convince, one or another half is practically not real. I expressed my opinion on this occasion
But in fact, the cause of disputes is not only in the beliefs and religious worship of this or another gasoline.
I want to consider the other side of the medal. The fact is that it is very often possible to hear from the owners, it would seem like the same cars, completely different impressions of using fuel with different octane numbers. Someone writes that the car does not go to the 92nd car, someone hears detonation and other nuances. And someone, on the contrary, haut 95th gasoline - type big consumption, the car is tupit, etc.
Why are such opposite reviews from the owners of the same cars? Of course, you can do everything, as usual, to write off on a different quality of fuel in different regions and at different gas stations. But let's leave it for those who have to blame for gasoline.
Let's try to figure it out according to Feng
The fact is that in spite of the same motors, the motors control units are not all the same.
Consider this in more detail.
Special electronic jumpers under the hood were installed on the first models for the Ukrainian market. In the schemes, they got a name that in translation denotes - okthan number switch.
I talked about this jumper in the article. By default, it was configured to Octan 91.
But, after some time, this jumper was removed, and by default, the ECU began to configure on Octan 95. Therefore, even in the operating instructions for the car in Lachevodov, different requirements for fuel used. Someone is not lower than 91, and someone has no lower than 95.
These changes are associated with more rigid ecology requirements, which did not allow, apparently, to use Octan 91.
From this point on, the dispute over the fuel used was aggravated, since someone went better at 92nd, and someone at 95th.
And some are convinced that no difference and all these settings give any effect, and the detonation sensor will help you to adjust the ECU to any octane number.
Well, what to say ... everyone has its own opinion and everyone has the right to think as he wants.
But if you do not think, but look at the real development of events, it can be noted that when switching the jumpers to 95, the starting uz on diagnostic charts really grows. And it can also be noted that the detonation sensor was literally a holy and almighty sensor that could fix almost any situation if you look at the diagnostic graphs, then the Cylinder Cylinder Correction begins only with a speed of 90 km / h ...
How to translate lacetti from 95 to 92
Despite the fact that the switching jumper of the octane number is abolished, this option remains in the engine control unit. And it does not work out any difficulty.
Consider this procedure on the Sirius D4 ECU, but these options are on other control units, including on and HV-240.
To begin with, we define exactly under what gasoline is your engine control unit, if you do not know. To work, we will need a wrench for 10 mm and an ohmmeter (multimeter).
First of all, we turn off the negative terminal from the rechargeable battery
... and remove the block with the ECU
We need the 27th contact of the ECU blocks. The extreme contacts are signed and calculated the necessary contact is not difficult. It turns out the fourth right in the lower row.
We connect the first multimeter probe to it. Not all probe get to contact, so it is convenient to use the segment of the wire
The second probe multimeter is connected to the "mass". It is more convenient to do this by connecting to the disconnected contact from the battery.
Set the multimeter to the resistance or "transverse" measurement mode and look at the testimony. If the resistance is minimal, then the 27th contact of the ECU is connected to the "mass", and this, in turn, means that the ECU is configured to the 95th octane.
In the photo below it is. 1.3 Ohma is the resistance of the probes themselves.
Clear? I repeat.
If the 27th contact of the pellets of the ECU is closed on the "mass", then the ECU understands it as the 95th Octan. And if the 27th contact is not closed on "mass", then the ECU understands it as the 91st Octan.
This can be done in two ways:
- Extract the 27th contact from the ECU block and leave it not connected.
- Cut the wire from the 27th contact. You can leave cut, and you can make a switcher or a "dad-mom" for quick switching between the 91st and 95th octane. Here is the choice for you.
To find the necessary wire, you need to remove the cover from the ECU block connector
We shift it forward
Remove the lid and find our fourth with the edge of the wire from the 27th contact
Here is this wire
Attention! I have a car with a jumper switching octane number under the hood, so I have a blue wire! On cars without this jumper, the wire will be black with a white stripe! The essence does not change!
To go to 92th gasoline, it suffices to cut this wire. And to re-go to the 95th, this wire must be connected again.
If you do not want to cut the wire, you can simply remove the 27th contact from the ECU block.
To do this, we subscribe from one end. Yellow plastic chip
Then from the other
And remove it.
We have contacts in all our glory. Now need a needle to squeeze the necessary contact and pull it out of the block.
We collect everything back and our car can ride the 92nd gasoline normally.
It is also desirable to reset adaptations using the Chevrolet Explorer program. Download, configure and learn to use you can in the heading
Here is a video How to translate Chevrolet Lacetti by 92-gasoline
From myself I will add that I am more like a ride on the 95th gasoline in the Ron Switch 95 position.
Well, what to do you and decide, actually you
All world and smooth roads!
The entire line of Chevrolet Lacetti engines is designed with the optimal ratio of efficiency and liter power. Fuel consumption is comparable to competitive models. At the same time, the machine provides sufficient dynamism, allowing the car owner to confidently feel both in the city stream and on the track.
The stability of the power plant and its durability depends on the fuel tank of the fuel tank. Therefore, the quality of the fuel is required to approach with the maximum responsibility and do not fill in the fuel in the fuel base from the dubious gas stations.
If gasoline consumption increased and no external factors changed, it means that the car should be given. The consumption rate that the automaker establishes, although it is obtained under ideal conditions, but still it is a guidance of the normal operation of the power plant. A sharp increase in fuel consumption very often suggests that repair requires a node or part of the power plant or related systems.
Fuel consumption with various engine volumes
The fuel consumption of Chevrolet Lacetti depends on which volume has a power plant, as well as from the checkpoint, which the machine is completed. Consumption 100 km on Chevrolet Lacetti Passport with 1.4, 1.6, 1.8 liters engines, given in the table below.
Table - Fuel Consumption Chevrolet Lacetti
Choosing gasoline
According to the manufacturer's recommendation, only non-ethydrated gasoline with octane number 95 and higher should be poured into a gas station. The fuel with a lower OK causes detonation in the power unit and can cause damage to the cylindrophone group.
Detolation damage appear on the use of low-fuel fuel in the power plant. They are easy enough to reveal. At the same time, the car owner risks losing free warranty repairs. Therefore, if you wish to reduce the cost of refueling, the choice between 92 or 95 should not be. In more detail, the behavior of the car on various types of fuel is shown in the table below.
Table - The effect of the octane number of driving a car Chevrolet Lacetti
Volume of fuel tank
The volume of the tank is designed in such a way that the car can overcome up to a thousand kilometers without additional gas stations. In more detail, the tank capacity of Chevrolet Lacetti in various bodies is shown in the table below.
Table - Chevrolet Lacetti
Car owner reviews suggest that real capacity allows you to pour up to 65-67 liters to the cut-off. This is due both to the "honesty" of the gas station and so that the volume of the tank is slightly more normalized.
Description of the reasons for a large fuel consumption on Chevrolet Lacetti and their solution
In the case of a worn motor, a valve slope or a rings running, a decrease in compression in one or more cylinders is possible. As a result, the fuel combines with less efficiency. This worsens the dynamics of the car and requires an increase in fuel consumption to maintain the desired speed mode. Elimination of the problem is possible only to the defect and replace damaged nodes or parts.
Real fuel consumption may differ from the norm due to insufficient pressure in the wheels. As a result, an increased effort is occupied required to overcome rolling resistance. To eliminate the problem, it is necessary to swing the wheels by controlling the pressure to the manometer.
A frequent problem of Chevrolet Lacetti is the twisting brakes. For diagnostics, it takes after a trip to control the temperature of the wheels of the wheels. The jamming brake warms them very much. For repair, it is necessary to replace the culprit of the subflinking, and after pumping the brake system.
Fuel consumption may increase due to the fill of low-quality fuel. The engine has to burn more fuel to maintain the required dynamics. Very often, falsification becomes the reason why the fuel filter and the grid are clogged. The solution of the problem is possible with a plum of low-grade fuel and washing the fuel line.
Effect on fuel consumption
Not timely replacement of consumables or their low quality is a frequent reason why fuel consumption increased. Thus, the fuel filter directly affects the air supply to form the fuel and air mixture. The drop in its bandwidth impairs the technical characteristics of the power plant and causes a great fuel consumption.
Crashing air filter
Ignition Candle, Oil and Oil Filter also directly affect fuel consumption. They require timely replacement and complete following the recommendations of the automaker.

. . As we see, gasoline on the gas station is becoming more expensive almost every day. It becomes more expensive oil - gasoline is becoming more expensive, it seems logical. The oil is cheaper - gasoline is still becoming more interesting, it is very interesting ... At the time of writing the article, the cost of 92 gasoline in our city has risen to 33 rubles. 90 cop. I no longer have time to change the price in the onboard computer. Do not have time to leave - the new price is already. Expensive is our public domain. While I am writing this article called a friend and said that the price of 92 is already 34 rubles. 90 cop. Now, if payments were so grew - maybe we did not pay attention. But in Russia, as always, everything is the opposite and through another place. "Upper mind Russia is not understood."
The ECU of our car is tuned at 95 gasoline, and it seems to be anywhere here. But I never respected 95, since it has more additives, and evapoability of it worseThan 92. And if it is also not very high-quality, many complain that with the onset of winter during frost -10, -15 they refuse to start the car, especially with autorun. In the north frosts are still church. There, the guys for the winter are diluted in half a 92 with 80 gasoline, he has evaporated even higher, otherwise the car does not start. Of course it is not - Hood, but they have no choice. If you believe the media, our oil refineries are due to the fact that only 92 gasoline can receive money on modernization, and all that is achieved above with additives. It sills in the tank 92 gasoline, and in the shower sad ... .., especially when the instruction manual comes into the hands. And there black on white it is written:
. . And here I recently appeared vibration. I thought the hydrophop of the engine was covered. This cushion is located on the right along the air filter. On the other hand, there is a simple rubber and bottom in the middle of the reference. I checked everything and found. It can be seen somehow provis the minus battery wire and rushing the engine. And the wire is powerful, and even at the factory it was closed with a fuse unit. Here is all vibration and passed from the engine through it on the body of the machine. While eliminated the problems, the thought came to mind - and does the engine work hard with me? He began to remember his cars with a battle. When you do later, the ignition falls, and the engine works softer. When earlier - the revolutions rise, and the engine is hard.
On 95 gasoline, the ignition is exhibited earlier (he has a detonation threshold above) than at 92. The ECU is tuned to early ignition - by 95 gasoline, and I fill 92, with a smaller octane number. So ignition should be done later. There would be a tramber - there would be no problems. It is necessary to adjust the brains by the car. We use the Internet. The official on this occasion is silent. If you believe the Ukrainian guys, then in the machines of their assembly there is a switching chip from 95 to 92. The Russian guys won - the search and did not find it. It turns out on the machines of the Kaliningrad assembly there is another ECU - Sirius D42. Here is a photo:
And these brains have no switching chips, and they are only 95 gasoline. I was saddened, again I remembered that I live in Russia, but did not fall in the Spirit. Climb again, but already on zavel sites with electricians, climbed on specials. Forums. And so on the bitches - in the girlfriend gathered these puzzles in her head and found a solution. Thinking for a couple of days, weighing everything, firmly decided to go to the garage, crossed himself, and the man said - the man did. Everything is very simple. Not ingable, five minutes, just ten gray hair (joke), and the brain of the car is already 92 gasoline. Naturally, it immediately wanted to try. I drove kilometers 5 and it seems nothing felt. I thought that morning the evening was wiser and went home. In the morning came, started and not understand. The car is cold, the turnover is increased, the garage is good acoustics, the sound should be louder. And then so quietly, gently, vibrations on the steering wheel are almost no. It can be seen during the night caught or the computer is not instantly rebuilt. I looked at the computer and noticed that the Woz (ignition advance angle was 3-5 degrees less. Previously, at acceleration on reduced gears, about 4,000 rpm I did not really like the Röv of the engine, but now I even became somehow pleasant. In general, time was spent not in vain. You can make cars of the Kaliningrad assembly with ECU - Sirius D42 to translate into 92 gasoline. I regret only one thing that did not think until that right away, as I bought a car. A young driver may not notice a big difference (the break is small between 95 and 92), but it will definitely feel that the car has become easier to breathe. I made a video, looking at which, everyone who interested this question may be in five - ten minutes to translate his Chevrolet Lacetti by 92 gasoline and if he wants, back to 95 (although this desire appears in a row). You don't need to buy anything, only hands are needed. Video instruction costs 250 rubles. We have a difference in price between 95 and 92 in 2 rubles. 50 kopecks Money will pay off for the first 100 liters, and then will save. Who is interested - go to the page to support the site.
. . But not all Chevrolet Lacetti Kaliningrad assembly need 95 gasoline. It all depends on the year of release and even the month. We bring quotations from FAQ on Lacetti:
. . A: For cars with Euro-3: According to the passport - not lower than AI-91, it makes sense to fill AI-95 only if it is completely confident in his quality, otherwise it is easy to kill spark plugs or ferrocene after a few fasteners (a red conductive flap appears on electrodes and insulator candles).
. . A1: For machines from Euro-4 (2007 release): on the passport you need to pour not lower than AI-95. Take a carefully user manual. Accurate to call the date Changes in the requirements of gasoline can not, unfortunately.
. . Maybe someone knows? So far, it was possible to calculate that March 2007 - not lower than AI-91.
Here I found a photo of the ECU - Sirius D42 with a removed battery:
Thanks to Evgeny Kondratenko for useful information. He wrote to me that immediately after the alteration, I connected a scanmar to the computer, where in parameters you can look under what gasoline brains. Before the alteration, the value was - 95, after it became 91. Remember before there were AI-91 and AI-93, now it was one A-92. There is no such option on my computer, I could only determine that the ignition was 3 - 5 degrees later, but on scandamics you can see specifically that brains switched and you can safely use 92 gasoline.
. . Many in letters ask a question, and for some reason, after after the ECU transferred to 92 - "Will there be any consequences for the car after such a rework?" I answer everyone at once. We do not convert anything. The switching option from 95 to 92 was introduced by our ECU developers themselves. But in order to deal with the ecology in 2007, they switched to Euro-4, using more environmentally friendly gasoline - 95, and this option could be said to be hidden. And we simply found it and use it. That's all. The engine in 2007 did not change. It was originally made under 92 gasoline - and remained. As there was a compression ratio of 9.5 - it remained. To translate engine itself On 95 gasoline, it was necessary to reduce the volume of the combustion chamber, thereby increasing the degree of compression. But nothing was done. They arrived easier - switched the ECU by 95, increasing the uzin, and removed from the wiring of our universal brains, the switching chip so that no one could think to use our native 92 gasoline. Many people think that on the 95th machine more powerful and more economical. Yes, I agree, but only when the engine itself is made under the 95th. The higher the degree of compression - themes and returns more. Now, if they took the head from the engine in 2007, and removed with her millimeter 2 (decreased the combustion chamber, thereby increasing the degree of compression) then - yes. So after the transfer of the ECU we go to your native gasoline. And there can be no negative consequences.
. . Many ask what will happen if not to translate the ECU and refuel by 92nd gasoline? Immediately nothing will be. I will tell such a case. In the 90s in our city, 92 gasoline disappeared somewhere for half a year. I just worked as a motorist in a taxi. Old Volga were on the 80th gasoline, and new and Muscovites 2140 on the 92nd. Smart drivers moved the battery and made the ignition later under the 80th. And "riders" and chased on the early ignition. After three months, engines with missing compression went to our engine shop. An autopsy showed an interesting fact - in cars that worked around the city burst and upper and lower piston compression rings. In intercity machines - only the top. In urban conditions, the load is more (traffic lights, constant accelerations). On the Internet, a lot is written about the consequences of early ignition. So you can read.
. . 04/14/2017. Recently, Damir from Neftekamsk wrote me a message. He has a car from 28.05.2007, and the most interesting thing is that the EURO is 0, and nothing is written in a book under what gasoline. After the inspection, they found out that the car under 95. And Nikolai Viktorovich writes that his car from 21.02.2007. Euro 4 and not lower than 91 gasoline. And there must be Euro 3. It can be seen in Kaliningrad in this 2007 transition to 95 gasoline was full of mess.
95 or 92 gasoline? These disagreements can be called classic for all motorists. Today, briefly and in your understandable language will answer this question.
Previously, the 80th gasoline was also participating in this "competition of the best gasoline", but he gradually left the market, as modern engines have a higher degree of compression and because of this, they need higher octane fuels.
It is because of the degree of compression, to more, and depends on the use of a particular gasoline. The greater the degree of compression - the greater the octane number of gasoline used.
I remember how before, in order to use low-fledged gasoline (76th or 80th), the car owners installed an additional gasket of the cylinder head, thereby reducing the compression ratio.
But time and technology do not stand still, the engines become more powerful, economical and less toxic. On sports cars, it has long been not enough octane number of even the 98th gasoline. Therefore, chemical additives are applied to fuel (additives) to increase the octane number.
What is better - 95 or 92 gasoline?
This question is much easier than everyone seems.
I use only 95th gasoline! Why? Because it is written in the instruction manual for my car
I know that many drivers with "foam at the mouth" prove that the 95th gasoline does not exist that there is additives and the like. So what, what is there additives? Additives are almost everywhere, including in engine oil, but for some reason it does not scare anyone. Good additives are chemical compounds that are designed to help the engine. Nothing in this is absolutely no. I am more than confident that soon this dispute will lose its relevance, since, in my opinion, the 92nd gasoline is waiting for the fate of the 80th gasoline. And this will happen in the near future. Here is the village aboutthrite.
It also makes it possible that the 95th gasoline is often formed. Of course fake. But also fake 92nd gasoline. There are quite a lot of people, there are quite a lot of hand, so fake all - ranging from gasoline and ending with cigarettes. Therefore, refuse gasoline with b aboutby the octane number due to the fact that someone makes something forgets, I consider not quite reasonable. You just need to refill your car on verified gas stations.
I hope that many pay attention as manufacturers write in the instructions - "95th or higher" or "not lower than the 95th". From this it follows that you can no longer, and less can not! And this is not a statement, any uncle Vasi with the car market, but the recommendation of the manufacturer! And so far the car is under warranty, this is not a recommendation, but the rule that must be followed in order not to lose warranty service!
Another misconception is connected with the detonation sensor. Inexperienced car owners think that the detonation sensor adjusts the ignition advance angle, and detonation from the low-octane gasoline used is not terrible.
It is also worth considering that if the detonation sensor reports a detonation, then several bursts of this detonation has already happened! And only then the ECU is changing the parameters! And how much is dangerous detonation for the engine I think it is not necessary to explain. I saw the piston killed by constant detonation. This is probably the most important enemy of motors.
Rings on candlelight from the application of 95th gasoline
Yes, this fact takes place. But this is not going anywhere yet. Until the more modern chemical compositions are used to increase the octane number, it will have to put up. Always for everything you need to pay, and this fact is no exception.
Better once every seven thousand kilometers than the engine detonation. This is my opinion.
Which gasoline is less expense?
This question will not even be considered, as I do not see the point absolutely. If the engine is designed for gasoline with an octane number of not lower than 95th, then the use of the 92nd for the sake of some savings in 50 kopecks is simply absurd.
What gasoline do you use? 95 or 92 gasoline
At the time of writing a small advantage on the side of the 95th gasoline.
The choice, of course you, but remember that detonation kills the engine.
P.S. I would like to note that you do not need to generalize this advice to all engines. It is the engines! Since engine manufacturers and car manufacturers are different things. The same engine can be used in different models of cars. And you need, first of all, look at the characteristics of the engine, and not on the car brand! For example, on the car of my wife is a motor that is recommended to use gasoline non-ettenited with an octane number of not lower than 91.
And those who want to get to the truth and understand why gasoline is recommended on some cars of the same model not lower than 91, and on the other not lower than 95 - read this small and draw conclusions
Take care of yourself and good luck on the roads !!!
