Changing the Oil in a Chevrolet Aveo T300 Manual Transmission

As the manufacturer of the Chevrolet Aveo indicated, the oil in a manual transmission cannot be replaced, i.e. it has a lifetime interval. However, it is recommended to regularly monitor the level of transmission oil in it. It should only be changed if the gearbox is repaired.

As Aveo operating experience shows, with a mileage of 80-100 thousand km, there may come a time when the gears begin to engage dryly, a small crunching sound appears, a hum occurs while driving, etc. According to experts, this is due to the fact that the manufacturer does not fill the box with expensive high-quality oil, which has a lifetime interval of use, but fills in cheap semi-synthetic, which during use absorbs fine abrasive, metal oxide, formed from friction, which as a result worsens the operation of its components and details.

A simple change of transmission oil helps solve all these problems (

It's a good day. Kicks appeared when changing gears. I changed the oil in the automatic transmission partly a week ago, the foam still remained. What could it be? I have a question about the box: besides the filter, did you change anything? (clutches, clutches, etc.) From time to time in “D” mode when parked, for example at a traffic light, the car starts to shake. Didn't you have such a task? Thanks in advance.

We did not have to change the parts of the transmission itself, because everyone who comes to us for service on such cars with low mileage, we show them the report that is posted here and explain what this can lead to. Accordingly, people agree to the correct replacement, and during the mileage the wear of clutches and other parts is still small.

Thank you. Can you tell me something about the shaking?

Needs to be opened. If there is extraneous noise, vibration and nothing to do, this can lead to disastrous results and expensive repairs.

Thank you. I'm thinking about it.

Thank you. Can you tell me something about the shaking?

The shaking is likely due to the motor mount. When you drive, everything is fine; when you stop, it starts to shake.

You see, it was important for us to show what happens in this automatic transmission at low mileage. We are not forcing anyone to change the oil in it every 50t, but simply giving advice on how to protect yourself from more expensive gearbox repairs. There are about 6-7 liters of oil in it, 500-700 rubles each ATF6 filter one thousand five hundred gasket two thousand five hundred work 8000-9000.

According to the regulations, the filter in the gearbox does not change because of. believes that it is for the entire service life of the car, which expires when your warranty expires. Let’s take, for example, the engine from my Ford S-max 2.5t car with a mileage of about 350,000t.

km maintenance regulations of 20,000 km, do you think the engine would have lasted to such a mileage while remaining in impeccable condition if I had adhered to the regulations?! I can tell you with complete confidence that no. and changing the oil every 7-8 thousand km left it in excellent condition.

And when you change the oil in an internal combustion engine, why change the filter? When changing the oil in ordinary gearboxes, where is the pan located that can be removed without much effort and the filter changed, why is it changed? When you answer these questions, I think you will find comprehensive answers to the question why change the filter)))

“...the entire service life of the car, which expires when your warranty expires,” then you would be left without a job. The car needs to be thrown away.

Sorry, but here it smells not ten thousand, but at least twenty, or even 30, there is 1 thousand oil per 5 thousand. Is it really worth shelling out such money every fifty 000 km? It’s kind of surprising that every fifty thousand cars need to actually have the transmission rebuilt. Although according to the regulations, a partial oil change is seventy five 000 - one hundred fifty 000.

When replacing and removing the gearbox, pay attention to all seals. Leaking of drive seals, gearbox seal behind the donut and crankshaft was observed on several cars. TAKE A CLOSE INSPECTION!

All automatic transmissions have a filter that needs to be changed)))

Kolya. On AF17, and even more so AF-40, there is no need to create such actions. It’s quite easy to periodically renew the fluid (by replacement)… Once every 60t.km.

Damn, this is a cheap B-class car. And every 50,000 km, pay off 20k? This isn’t some kind of Porsche turbo, or a BMW M5, which they use all the time. It’s an ordinary vegetable car. Well, why would you remove the box every 50,000 km, well, what the heck?

Don't scold the elephant, otherwise you won't sell it.

We don’t even think about it. My wife drives while there are other difficulties in order to change the car. When the time comes, it will go, where will it go)

Transmission oil change interval

This box was installed on front-wheel drive vehicles with an engine capacity of up to 2.4 liters. The manufacturer advises changing the oil in the car’s automatic transmission after a mileage of 150,000 kilometers. But this figure is taken from calculations of normal operating conditions.

Russian roads and climate are not normal conditions. And many novice drivers who do not know how to handle a car in the cold season, with an automatic instead of a manual, turn these conditions into extreme ones.

In extreme conditions, it is recommended to change the oil every 70,000 kilometers, making a complete change of lubricant. I recommend performing a partial oil change after a mileage of 30,000 kilometers.

Attention! Check the lubricant level in the Aveo T300 automatic transmission after a run of 10,000 kilometers. And along with the level, do not forget to look at the quality and color of the oil. If the oil in the automatic transmission has darkened and you see foreign impurities in it, then urgently change the lubricant to prevent damage to the Aveo T300 automatic transmission.

If you haven't changed the oil and when driving you hear:

Read Do-it-yourself complete and partial oil change in the Lada Granta automatic transmission

First of all, replace the lubricant. All these signs of bad oil should disappear. If they remain, then take the car to a service center for diagnostics.

Useful tips

As you can see, the method of partially changing the oil without removing the pan allows you to delay a complete oil change and increase the service life of the unit. At the same time, the Aveo automatic transmission requires about 3 liters of oil.

The only thing is that in this case you should repeat this procedure every 15 thousand km or even earlier, then drain again and partially fill in fresh oil to update it in the automatic transmission. By the way, in order to achieve maximum effect, the total amount of oil may even exceed that which is required for a one-time complete hardware replacement. To this you can add the time lost to complete the procedure.

We also recommend reading the article on how to service an automatic transmission and change the oil in an automatic transmission. From this article you will learn how to change the oil in an automatic transmission, as well as what subtleties and nuances to pay attention to during this procedure.

If you change the oil by spilling, at the same time cleaning the automatic transmission radiator and changing the filter, as well as cleaning the pan, then you will immediately need about 8-10 liters or more, as well as a new automatic transmission pan gasket and automatic transmission oil filter. At the same time, after 10-15 thousand, it is recommended to additionally perform a partial replacement without removing the pan to completely update the ATF fluid.

Taking into account the above, you can determine what is better, limit yourself to a partial replacement, or immediately contact a service station, where the replacement will be carried out in full, the automatic transmission pan will be removed and cleaned, the automatic transmission filter will be replaced, etc.

Naturally, such a complete hardware replacement of ATF using the displacement method will cost more, but in the future the automatic transmission will not require maintenance in the next 50-60 thousand km. (provided that the automatic transmission is in full working order and no unexpected breakdowns occur during this period).

How to change the oil in an automatic transmission 6t30e

Partial ATF replacement can be done independently in just half an hour. The main thing is that all consumables and the oil itself are collected. We will also make sure that the waste is drained into a container of at least 5 liters.

We carry out the replacement according to the following algorithm:

We place the car on the pit and unscrew the protection. Two bolts in front and two in back.
With the engine off, drain the oil through the drain plug. We wait until all the oil has drained, screw the plug into place, checking its condition.

We put the protection in place, checking for drips on the plug and on the control plug. After a short mileage (up to 500 km), it is advisable to check the oil level again.

Checking the volume and condition of the oil

To check the oil level, you will need a dipstick, which is located under the hood of the car.

To check the fluid level, you will need a special device - a dipstick. It is located in the engine compartment. It shows the Max and Min marks, by which you can determine the need to add oil.

If the fluid print on the dipstick is below the Min standard, it indicates an insufficient level. In this case, the liquid is added without exceeding the Max mark on the dipstick.

If, with high mileage, the oil becomes cloudier or changes color to a darker one, this indicates that the oil will soon become unusable. The suspicious composition of the oil and its specific odor indicate that the oil is unsuitable. In these cases, it is necessary to change the oil.

The car enthusiast must dismantle the protective part of the pan (of course, if there is one), unscrew the bolts (3 pieces), remove the stretcher from the subframe - it interferes with disassembling the transmission pan.

We use a brush to clean the surface of the pan that is pressed, as well as the plug that closes the drain, then twist it and wait for the used oil to pour out.

After waiting for the fluid to drain, close the hole with a plug, and then unscrew the bolts located at the edges of the transmission pan.

Now the pan can be easily removed, and you can easily remove any remaining oil from it. We remove the gasket and carefully wash everything (for example, with gasoline or another cleaner).

We unscrew the bolts that hold the oil filter (usually there are three of them), and then dismantle it.

We install a new filter in place of the old one.

Now on the cleaned surface of the pallet we install magnets in the appropriate areas, as well as a gasket. Then the pressure part of the gearbox should be degreased and also cleaned. Having completed these manipulations, we return the removed parts to their places.

Using a special neck, fill in the purchased lubricant (the hole into which the dipstick is placed). The volume of oil poured should be approximately 2 liters, then you should alternate gears without starting the engine. Then add one liter of lubricant and start the engine. We put the automatic transmission into park and check the level with the engine running.

With slight delays, we change gears (while the engine is running), fix the lever in the “P” state.

At the last stage, you should warm up the engine to the operating, standard level. Gradually add oil on the gearbox dipstick. We check the fixed pan for fluid leaks; if there are no problems, we return the elements that protect the crankcase and, accordingly, the extension to their places.

So, now you know how to change the oil in a Chevrolet Aveo T300 automatic transmission.

Why might oil leak?

A lack of fluid in the automatic transmission leads to slipping of the friction discs and problems when shifting gears. This may be almost unnoticeable on a flat road or downhill, but more significant loads (when accelerating, on an uphill slope, or during heavy stop-start traffic) lead to overheating of the box and can damage it.

What causes a lack of oil in an automatic transmission? A small amount of oil in the gearbox evaporates during operation; this is a natural phenomenon. Usually it does not have a critical effect on the pressure; the transmission fluid will quickly lose its properties as a result of depletion. Sometimes the culprit is not adding enough oil at the last change. This can be easily corrected by measuring its level and adding the missing amount.

The most dangerous problem is oil loss due to leakage. This can happen as a result of wear of the oil seals and O-rings, as well as in the event of mechanical damage to the oil pan, which happens when the driver hits a high obstacle.

In this case, you should tow the car to the nearest service center as soon as possible for diagnostics and oil change in the automatic transmission on the Chevrolet Aveo T300. It is best to do this with the help of a tow truck, but if it is impossible to call one, towing is done under its own power using a cable.

When towing a Chevrolet Aveo, you need to remember two things: to avoid complete destruction of the gearbox, transportation should occur at a speed of up to 50 km/h for a distance of no more than 50 km. When transporting, the gear selector must be set to position N.

Which oil is better to choose for a manual transmission in a Chevrolet Aveo?

In contrast to an automatic gearbox, where oil (or more precisely, a special transmission fluid) is the so-called working fluid that transmits torque. And also in a diesel tracked vehicle, with the help of oil pressure, the crankshaft is rotated for ignition (for example, most army tracked chassis are started in the indicated way); there is no torque converter or oil pump in the mechanics. So why is there oil in a manual gearbox at all?

In a manual transmission, the lubricating fluid performs the following three most important functions:

For starters, it's a lubricant. In the presented case, everything is simple - the gears of a manual gearbox (MT) are in mesh. If lubrication is present, the designated gears engage more smoothly, resulting in slower wear. This is due to the fact that there is no or very little friction in the presented situation;
In addition to what is indicated, oil removes wear products (small metal particles, chips) from parts that rub;
Protection. The oil that covers the parts of a manual gearbox (MT) creates a certain protective layer that protects them from corrosion, friction, and oxidation. All this also extends the period of operation of the unit in question;
The oil also removes heat from the manual transmission (partial cooling). When a Chevrolet Aveo vehicle is in motion, the oil temperature in the manual gearbox is on average 150 degrees Celsius. The temperature at the points of contact of the gears that are in mesh is approximately twice as high as previously indicated.

Thus, the lubricant that washes over the gears cools them slightly. Based on the information presented, we conclude that even a small volume of oil in a manual gearbox (in a manual transmission there is about 2.5-3 liters of lubricant) can extend the service life of the transmission. As already indicated above, oil is even more important for automatic gearboxes.

A large number of vehicle owners choose synthetic oils. This is due to their working properties. The following gear oils are suitable for manual gearboxes: SAE 75W-90/SAE 80W-90, which belong to the GL4 class. ESSO JWS 3309 fluid is suitable for automatic gearboxes.

Frequency of oil changes in a manual gearbox (MT) on a Chevrolet Aveo.

Manufacturers of the Chevrolet Aveo brand vehicle state that the factory oil in a manual gearbox is designed for the entire service life of the vehicle. On the one hand, the above statement is reliable. The presented conclusion can be drawn from the positive reviews of the owners of the car in question living in European countries with a favorable climate.

As for the operation of a Chevrolet Aveo vehicle in harsh climatic conditions, in this case the situation is not clear-cut and depends on road and weather conditions. An unfavorable climate negatively affects the working properties of the oil, which causes it to deteriorate faster.

As a result, the need to replace the lubricant arises much earlier than indicated in the official operating manual for the Chevrolet Aveo. Based on the information presented, we can conclude that in Russian conditions it is better to change the oil in the manual gearbox of the vehicle in question after 20-25 thousand kilometers.

The owner of a Chevrolet Aveo should change the oil in a manual gearbox if any of the following symptoms appear:

When checking the oil, the car enthusiast discovered that the color of the oil had become darker than it should be;
The lubricant gives off an unpleasant burning smell, which is not typical for vehicle lubricants;
Switching does not occur in an optimal mode, systematic problems arise;
Obvious noise from a manual gearbox (MT) on a Chevrolet Aveo in neutral;
Vibrations and shaking sensation;
Delay or complete lack of reaction to the actions of the owner of a Chevrolet Aveo vehicle: relevant for both manual and automatic gearboxes.

It should be noted that the above signs do not always indicate that there is a problem with the transmission oil, however, there is no need to hesitate in checking it, but it is recommended to start with self-diagnosis of the lubricant or manual gearbox.

How much lubricant should be poured into a manual gearbox (manual transmission) in a Chevrolet Aveo?

When replacing or topping up the lubricant yourself, it is important for the car owner not to overdo it with the amount of oil. This is important because if a car owner who owns a Chevrolet Aveo vehicle overdoes it with the amount of oil, this can lead to breakdowns.

To find out how much oil a manual gearbox of a Chevrolet Aveo car holds, its owner should read the car’s operating manual. This is the easiest and also the correct way. Each motor requires a certain amount of lubricant.

More about Aveo: Chevrolet Aveo ground clearance: description, increase, spacers

According to the information provided, determining the amount of oil required is based on a strictly specific car model. The Chevrolet Aveo is equipped with a wide variety of types of power units, so there is no single quantity. For the most common types of engines, the volume of transmission oil poured into a manual gearbox (MT) is as follows:

Z6 of all years of manufacture with manual transmission – 3.9 liters;
LF 17 – from 2.87 to 2.9.

If, for any reason, the owner of a Chevrolet Aveo vehicle has certain difficulties with access to the official documents of the car, and to information about the type of power unit in the car in question, the amount of oil for a manual gearbox (manual transmission) can be determined using a crude artisanal method .

Beginner car enthusiasts use this method quite successfully. When there is enough lubricant, it will flow out of the filler hole. Afterwards, the owner of a Chevrolet Aveo car needs to try to suck out the excess amount of lubricant, and also wipe dry all parts of the vehicle that have received transmission oil.

Features of manual transmission

Using a manual gearbox (MGT), it is possible to regulate the speed of a Chevrolet Aveo vehicle. In first gear the car starts moving. In the presented gear, the speed cannot reach more than 60 kilometers per hour. Next, the car owner has the opportunity to gradually increase the speed; to do this, he needs to switch to second, third, fourth gear.

The design of a manual gearbox is quite simple and operates on the principle of a gearbox. Gears of different diameters with different numbers of teeth are mounted on two shafts. For example, if there is a gear on one shaft, which engages with its teeth a second gear, the size of which is smaller in diameter than the second, then the second gear will transmit a lower speed to the shaft, and therefore to the wheels of the vehicle. This is due to the fact that a large gear will be slower to complete a full revolution. And vice versa, if the first gear is larger than the second, the speed is 2nd, which means the second shaft will be larger, as a result of which the wheels of a Chevrolet Aveo car will rotate faster. There are several pairs of gears presented above in a manual gearbox (MT). Their number depends on the number of speeds of the Chevrolet Aveo vehicle.

The higher the speed of the car, the less power that is transmitted by the first gear to the second, as well as to the second shaft and wheels of the vehicle. Based on the indicated information, we conclude that at fourth speed the car owner will not move the car from its place. When a Chevrolet Aveo is in motion, it is easier to keep it at a certain speed than to move it from a resting state. To carry out the indicated action there is no need for high power.

Draining waste fluid

It is necessary to drain the used engine fluid when the engine is warm. This is due to the fact that heated oil is more liquid. This makes it easier for it to leak out of the thin channels of the lubrication system.

The replacement can be made on any level surface, because it is not necessary to remove the engine protection on a Chevrolet Aveo. It has a special hole designed to drain the waste. But since we are changing in a pit, we removed the protection, so the draining process will be more accurate. The bolts that secure it are set to 17 key.

When everything is ready, we proceed to the draining operation:

We lift the hood, find the filler neck on the engine, and unscrew the plug that closes it (Fig. 1).

Fig.1 Oil filler neck

Now we go down under the car and place a waste container in the drainage area. You can use a cut canister or an old bucket.
Unscrew the drain plug using a Torx T45 sprocket (Fig. 2).
Fig. 2 Drain plug Under the hood in the front of the engine there is a plastic housing for the filter element. We unscrew it using a 24mm socket. First we place a rag under it so as not to smear the motor with the workings (Fig. 3).
Fig.3 Filter element housing
Using this method, you can drain the maximum amount of used oil, after which you can proceed to further actions. The main thing is not to forget, everything that we unscrewed must be put back in place.
Flushing the lubrication system
Engine flushing on a Chevrolet Aveo should be carried out only in exceptional cases, which include:
1. Purchasing a used car when you cannot know about the quality, as well as the regularity of lubricant replacements.
Engine operation with constant frequent overheating, which contributes to coking and other deposits.
In cases of switching to another type, for example from synthetics to semi-synthetics.

There are several types of flushes for the Chevrolet Aveo engine:

Five- or seven-minute, capable of cleaning even the most difficult deposits. They must be used very carefully and strictly follow the instructions printed on the packaging. It is recommended to use them only when absolutely necessary. Since there is a high probability of causing premature wear of the sealing seals. And also clog the oil channels with particles of washed away carbon deposits.
Special compounds that are added to the oil several hundred kilometers before the expected change. They are more gentle, but there is also a possibility of clogging of the oil channels.
Flushing oil is the most gentle method of cleaning the engine from the inside. This composition is poured after draining the waste, the engine runs for 15-20 minutes, after which the liquid with deposits is drained. The absence of aggressive additives in the wash composition gently cleans the engine, but is not able to remove heavy contaminants.
Regular oil that you are going to use when changing. This method is not so popular due to its high price.

Installing a filter, filling in new engine fluid

If the Chevrolet Aveo lubrication system is sealed and does not require repair work to eliminate leaks, you can proceed to adding fresh oil. In addition to the oil itself, for the 1.6 engine we will need a new rubber sealing ring for the drain plug GM 90528145. As well as the original GM oil filter 93185674.

Consumables for maintenance

When everything is ready, let's move on to the bay:

We put the drain plug in place, it is advisable to replace the rubber O-ring.
We wipe the seat under the filter element housing.
We put a new rubber ring on the plastic case, first lubricate it with fresh oil.
We tighten and install the housing with a new filter element.
Pour new oil into the filler neck.
We check the level on the dipstick; it should be between the MIN and MAX marks.
We start the engine, let it run for 10-15 seconds, then turn it off.
After 5 minutes, check the level with a dipstick and top up if necessary.

Checking the level, adding and changing oil for Chevrolet Aveo T300

HELPFUL ADVICE: It is recommended to drain the oil within 15 minutes after the trip, until it has cooled down and has good fluidity.

NOTE: For manual transmissions, use API GL4 SAE 80W-90 or SAE 75W-90 oil. The manufacturer recommends replacing the oil filled at the factory with SAE 75W gear oil if the vehicle is operated for a long time at ambient temperatures below -30°C.

To check the oil level, top up or replace it in a manual transmission, perform the following operations.

1. Remove the engine crankcase protection (see “Removing and installing mudguards and engine crankcase protection”).

2. Loosen the oil level plug located on the side of the gearbox housing and remove the plug. 3. The oil level should be at or slightly below the edge of the hole (you can reach the surface of the oil with a screwdriver or your finger).

4. If the oil level is very low (cannot be checked with a screwdriver or finger), remove the cap from the oil filler plug located on top of the gear shift housing.

5. . loosen the plug.

6. . and turn it out.

NOTE: The oil filler plug doubles as a breather, so make sure the holes in it are clean.

WARNING: Operating the vehicle without the protective plug cap is prohibited! If it is missing, road dirt will get into the gearbox.

7. Fill the oil with a syringe into the hole in the gear shift mechanism housing until it appears from the inspection hole. Close the inspection hole plug.

HELPFUL HINT: The plug has a magnet to collect metal wear debris; clean it before installing the plug.

8. Tighten the oil filler plug.

9. The design does not provide a plug for draining the oil, so if it is necessary to change the oil, install a container under the gearbox to drain the oil, and remove the bolts securing the lower cover of the gearbox.

10. . and drain the oil. 11. Remove the cover and gasket. 12. Wipe the cover and gasket with a clean rag to remove any remaining oil.

NOTE: Replace the gasket with a new one each time the bottom cover is removed.

13. Install the lower cover of the gearbox and fill in the oil as you did when checking its level and topping up (see paragraphs 1-7 of this subsection).

Leaks and problems

The longer the Chevrolet Aveo's mileage increases, the more problems appear, as in principle with any car. Most often this is due to natural wear and tear of the engine, causing oil to burn. Although the manufacturer allows for a small consumption.

In communities about this car you can find information that engines are very sensitive to bad oil. And if you fill in a high-quality product, there should be no problems with fat, no more than 500 milliliters from replacement to replacement.

But on some engines, there is a common problem, oil in the spark plug wells. The reason for this lies in the valve cover gasket, as well as the sealant that has ceased to perform its function.

Therefore, to eliminate leakage into the spark plug wells, we change the valve cover gasket. After first removing the old sealant and cleaning the seating surface with a cleaner.

When carrying out this procedure, it should be taken into account that the sealing rings under the bolts require replacement. The original ones are expensive, so you can look for one from Kamaz, article number 7401003040. They are suitable for many engines of this model.

The most problematic engine in the family is considered to be the 1.5 liter. Many owners complain about oil consumption. Most often, the culprit is the valve stem seals or coking of the piston rings. Although there may be many more options for problems with increased consumption.

All this is general information, which may manifest itself differently on each specific vehicle, since everyone’s operating modes are different. The same applies to leak locations; it is impossible to identify the cause from a distance.

Replacement process

To change the oil in a Chevrolet Aveo automatic transmission, you will have to study a little the technical characteristics and design features of the vehicle. So, you should understand that you will have to dismantle the pan and wash it.

Chevrolet Aveo T300.

According to the technical documentation, the Chevrolet Aveo automatic transmission contains 3 liters of oil. When changing, 2.75 liters / - 10% is usually sufficient. But, if flushing is carried out, all three liters will be required. Let's look at the replacement process itself:

We install the car on an overpass or pit. Of course, if you have your own lift, then the task is simplified.

We remove the battery terminal so as not to short-circuit anything accidentally.
We climb directly under the car and place the container opposite the drain bolt from the automatic transmission.

Unscrew the drain plug.

Smoothly unscrew the bolt and wait for the oil to drain.

The process of draining oil from the box.

Now, unscrew the screws securing the pallet and remove it from the car.

We install a new gasket and mount the pan in its seat.

Install the new pan gasket.

We take out the oil dipstick in the box. We will pour new liquid through it. If you don’t have a special watering can, you can do it yourself using a hose with a diameter of 10 and a plastic bottle.

We fill in new oil through the dipstick.

Disconnect the return hose. Then we connect the washing tube, and the second part into the bottle.

Disconnect the drain hose to flush the automatic transmission radiator.

We get behind the wheel of the car, start it and start going through the gears with a delay of 3-4 seconds. This is necessary to flush the automatic transmission radiator.

Having unscrewed the return line, set the hose to 10 to flush.

We put the unit back together and top up the oil.

Drain flushing from the automatic transmission radiator.

Now, the oil in the system has been changed. Flushing the radiator may require up to 7 liters of oil.

Fuel consumption

As for fuel consumption, this figure is lower when using a manual transmission. More detailed information on the amount of fuel used per 100 km is given in the table.

It is also worth noting that most owners of the Chevrolet Aveo T300 assure that the actual fuel consumption of the car differs from that stated by the manufacturer. Thus, according to some car enthusiasts, an Aveo with automatic transmission consumes 8.5 liters of gasoline per 100 km with a calm driving style in mixed mode (highway + city); with manual transmission - 7.6 liters per 100 km under the same conditions.
