Since I am very meticulous in everything (and even more so when it comes to the car). Therefore, I cannot just take and fill in any standard oil. I would like to know as much as possible about this!
Therefore, I surfed the Internet for a couple of days, re-read a lot of information, and have already drawn some conclusions for myself! But I still want to hear your opinion on this issue!

Who is which oil?
- Which company?
- What viscosity grade?
- And in general any interesting information on the issue of changing engine oil?

In the instruction manual “ Chevrolet Lanos” approved for engine use motor oil with quality classes API SJ or ACEA A1/A2/A3 and higher quality classes, as well as having a viscosity of SAE 5W-40, SAE 10W-40, SAE 15W-40.

Manufacturer " ZAZ lanos”recommends: API SH ACEA A2/AZ SAE 5W-30, SAE5W-40, SAE 10W-30, SAE 10W-40, SAE 15W-40. It is clear that SAE 10W-40 and SAE 15W-40 are recommended for use only in the warm season, and synthetics SAE 5W-30 would be better suited in winter.

In addition to viscosity and quality class, there is also such a parameter as the engine manufacturer’s approval (this is the engine manufacturer’s own standard, which indicates that the oil contains everything necessary for use in its engine). For use in Chevrolet engine Lanos is suitable for oils with Opel GM-LL-A-025 approval.
In Lanos, most services use GM 5W-30 Super Synthetic synthetic engine oil. In addition to this motor oil, there are several other oils now on the market with approved viscosity, quality class and certified to Opel GM-LL-A-025 approval.

These are the oils:
ELF Excellium GM 5W-30.
ELF Evolution SXR 0W-30.
Mobil 1 New Life 0W-40.
Castrol EDGE SAE 0W-30.
Shell Helix Ultra AG SAE 5W-30.

Specifically for my car:
Currently I have Mobil Super 3000 X1 Formula-FE (5W-30) engine oil.
About of this oil I will say: The oil seems to be good.
In winter, the car starts very easily, the engine runs quietly, already 10 thousand/km. passed on it, and the oil on the dipstick is like new. In general, I was pleased with them!
It is possible to order oil from Poland (I think the quality will be better there, and there will be fewer fakes), but I don’t know what good brands they have there! Maybe someone can tell me?
There are so many manufacturing companies that it is very difficult to choose: GM, MOBIL, SHELL, CASTROL, MOTUL, LIQUI MOLY, etc. And most importantly, you really want to buy quality oil not a fake! In short, I'm confused (...
I have one option in mind, but I don’t know if it will fit into our engine, and most importantly, won’t it do any harm?

“Castrol 0W-40 EDGE Formula RS Oil”

“””WHAT DO YOU SAY ABOUT THIS”””?

P.S. Here’s the question I’m actually interested in: Should I stay on the same oil parameters (Sentnika 5W-30). Or maybe something can change? And which brand of oil is better to buy?

Typewriter Daewoo Lanos 2007 “Polyak” - 1.5l. 8V. Mileage 82 thousand/km.
Standard engine:
-Function/release slightly improved.

My driving style is far from calm, I often rev the engine to 5000-6000 rpm.
I like to get into the cut-off)…

So, dear readers. The time has come for us to discuss which motor oil is best suited for the pride of the Ukrainian automobile industry, people's car ZAZ LANOS, aka DAEWOO LANOS, aka DAEWOO CHANCE, aka CHEVROLET LANOS.
For the sake of objectivity, we will look at this small but proud bird under the microscope of the chronology of production in the world:

OPEL KADETT– indeed, the A15SMS 1 5 engine installed on DEO LANOS is a modified version of the G15MF 1.5 (installed on Daewoo Nexia before restyling), which, in turn, was copied from Opel engine C16NZ, designed back in the 80s. For such Opel engines at one time recommended motor oil class API SF/SG/SH (one version) and API SF/SE (recommended in more than one version) old instructions manual).

The answer is clear - yes, nothing will happen, but with the caveat “for how long” or “how long to ride it.” After all, in the 70s there was no concept of “extended oil change interval” and oils were worn out much earlier than modern ones. It was from this era that the opinion came to us that if the oil has darkened, it needs to be changed urgently.
Those who are especially savvy have probably already guessed that since the “old” version of the instructions recommends more outdated classes of oil, and the “new” version recommends more modern ones - then the more modern oil- the better it is. And there is a grain of truth here. But our task now is not just to find out “which oil is the best in the universe”, but to determine that golden mean between “MOST” and “UNREASONABLY EXPENSIVE”, because among the owners of DEO LANOS you rarely meet a person who is ready to spend easy money on an oil change. At the same time, you need to figure out which product will prove itself BEST in the price segment of the owner of “our hero”.

1.Original oil under the GM logo.

Since DEU LANOS is stuffed from head to toe with logos of this brand, many quite rightly believe that it should be poured original oil G.M. Incredible, but true - GM does not produce the oil itself (just like other original oils). The oil is made for him by the one who offers the most favorable price for a product that meets the requirements stated by the car manufacturer. WHO ARE THEY? MANUFACTURERS? There are quite a lot of versions today: LUKOIL at factories in the Russian Federation, Turkey and Romania, the British “WOLF” (before that Castrol, Elf, Delco). Both versions have quite significant confirmation on “oil forums” - from certificates to photographs of canisters indicating the manufacturer. But for sure, we only know what we can see with our own eyes (see photo).

Yes, yes, in Turkey GM produces LUKOIL LUBRICANTS MIDDLE EAST MADENI YAĞ SAN. And all Turks, by the way, with a population of 80 million people, have been driving TURKISH GM for a long time (by the way, the vehicle fleet there is much fresher than ours, and there are generally more cars).

It also sounds quite plausible that the oil sold on the territory of Ukraine is, for the most part, the same Romanian LUKOIL plant, with the legal indication “made in EU” on the canister.

2. Oils of “domestic” production.

Since our online store www.site is located in Ukraine, from personal observations I can state the fact that about half of the owners of “people’s” cars in Ukraine, over time, switch to cheap oil, often domestic production. In general, there is nothing wrong with this, but you should be careful and pay attention when choosing domestic oil to the following:
1) Viscosity index this product should be at a fairly high level. And this is due to the fact that not all so-called “semi-synthetics” are produced using “synthetic raw materials”. Often manufacturers are cunning and, in order to reduce the cost of the product, replace the synthetic base with an unreasonably large number of viscosity additives. However, this does not make the oil “synthetic” or “semi-synthetic”. So it turns out that you are buying a “semi-synthetic”, but in fact it is a “mineral water” with a viscosity of 10w-40. Before buying oil, don’t be lazy, go to the manufacturer’s website and look at the plate with technical characteristics. If the viscosity index in it is about 130 units, this is probably the case. If the viscosity index is about 150 or more, then most likely you have a “real semi-synthetic”, “synthetic”, or “synthetic” product. In other words: the higher the viscosity index, the higher the safety margin!

2) API class- the higher, the better. Pay attention to the following: SN is better than SM, SM is better than SL, etc. descending - SN, SM, SL, SJ, SH, SG, SF (see API picture above). Accordingly, keep in mind that the SG class is a standard valid from 1989 to 1992, and SN appeared in 2011, and to this day there is nothing better than this class. Moreover, if the API classes are confirmed by the API itself (API - American Petroleum Institute or American Petroleum Institute) - generally excellent - then this oil at least corresponds to the class that is written on its canister. If the API knows nothing about it, then no matter what class is written on the canister, it means absolutely nothing, and there is NO confidence in the quality of this product (or under the guise of SN, for example, they sell you SG)! Judge for yourself: CASTROL, MOBIL, SHELL, TOTAL, ELF, and LIQUI MOLY are certified according to API classes, but some “pseudo-German” oil in a tin can is not. Draw conclusions. The easiest way to check this is directly on the API website - https://engineoil.api.org/Directory/EolcsSearch. Using the example in the photo below, you can verify that the quality level of the requested product corresponds to its description, officially verified by the American Petroleum Institute. By the way, LUKOIL oil has more than 70 such confirmations https://engineoil.api.org/Directory/EolcsProductResults?accountId=-1&brandName=lukoil

3. Viscosity

The optimal viscosity for our climate is SAE 5w-40 and 10w-40. But in general, AVTOZAZ, as you have already seen, regulates a fairly wide range (depending on climatic conditions). In the latest edition of the manual from ZAZ, these are 5w-40, 10w-40 and 15w-40 (according to one version of the manual, even 5w-30, although in fact there is no urgent need for such a “non-viscous” oil).

4. Availability of official approvals

Having official approvals from car manufacturers is an additional advantage. However, keep in mind that for the Lanos engine, there are no special requirements for approvals from GM. Requirements, by the way, as well as API classes, can be checked online. It is advisable to do this. Since recently, manufacturers of the so-called “GERMAN OIL” have entered the market, bottled at the same domestic factories, posing as a “quality German brand”. Read any approval on the canister and check its relevance with the information on the website of the issuer of the approval. For example:
Mercedes Benz - https://bevo.mercedes-benz.com/bevolisten/bevo-blaetter-sort1.html(select required clearance)
GM - www.centerforqa.com/dexos/ (select Dexos 1 or Dexos 2)
and so on.

In 2012, on the basis of the Melitopol Motor Plant on the ZAZ SENS engine ( younger brother Lanos) MEMZ-307 Public Joint Stock Company "ZAZ" tested LUKOIL LUX API-SL 5w-40 motor oil (note even “semi-synthetic”) to assess its quality and possibility of use in production, according to the “FAILURE-LOSS” engine test method. After this event, for the first filling at PJSC "ZAZ" during the assembly of ZAZ LANOS, ZAZ VIDA (clone Chevrolet AVEO) , ZAZ FORZA, ZAZ SENS it was decided to use LUKOIL TM oil. And under the hood of these cars there was a sign “ZAZ recommends LUKOIL LUX oil.”

Somehow, a few years ago, I came across a well-known forum about oils, from which I managed to borrow these photos:

We often receive questions related to the choice of engine oil for Daewoo Lanos.
Car owners are looking for answers to basic questions:

• What kind of oil should I pour into Lanos?
• Is synthetic or semi-synthetic better suited to Lanos?
• Original oil for Lanos?

We will give you answers to these and other questions that will be relevant when choosing oil for Daewoo Lanos and Sens cars.

Manufacturer's recommendation for the use of oil in Daewoo engines
Depending on climatic conditions, the manufacturer recommends filling Lanos with oil with a viscosity of 5W-40, 10W-40 or 15W-40. The oil quality level in Lanos must correspond to API SJ or ACEA A1/A2/A3.

What does the oil marking say?

The motor oil manufacturer took care and produced oils for different climatic zones of the planet. The viscosity of the oil for Lanos is selected depending on the operating temperature conditions. In the marking, the first numbers (5W, 10W, 15W) indicate low temperature oil viscosity, in which the oil pump is able to pump oil through the system and supply it to the working units, without allowing dry friction. Moreover, the engine cranking temperature is 5 degrees higher than the pumping temperature, i.e. If you were able to start the engine in cold weather, then rest assured that the oil is able to be pumped through all oil channels and fully perform its functions.

SAE class	Low temperature viscosity
	Turning, t	Pumpability, t
	30 0 C	-35 0 C
	-25 0 C	-30 0 C
	-20 0 C	-25 0 C

High temperature viscosity(5W 30 , 10W 40 ) is a general indicator of the minimum and maximum oil viscosity at operating temperatures of 100C and 150C. The higher this number, the higher the viscosity of the engine oil at operating temperature engine. When independently selecting oil for Lanos, this indicator should not be higher than that recommended by the manufacturer, otherwise this will lead to an increase in load, a drop in power and increased engine wear!

Oil quality for Lanos
All produced oils are tested and receive quality certificates. The belonging of an oil to a certain class fully characterizes its properties and qualities.
Classification of oils for Lanos according to the American Fuel Institute standard is marked - API SJ. This means that oils of this class are designed for use in gasoline engines since 1996 release. Used in passenger cars and sports cars, minibuses. Provide established standards and are serviced according to the requirements of vehicle manufacturers. Have additional requirements to work at low temperature and minimal carbon formation.
In Europe there is a quality certification similar to the American standard - ACEA. IN European classification The quality of oils for Lanos is set to quality A1/A2/A3, which provides for the possibility of using oils from standard to high quality.

Synthetic or semi-synthetic oil Is it better to pour into Lanos?
The manufacturer recommends using mineral, synthetic and semi-synthetic oils in Lanos. The fundamental difference between mineral and synthetic oil is in the special structure of the molecules that were created through synthesis.

Synthetic oils have improved properties:

• retain their properties longer during operation
• more resistant to overheating and changes in operating temperatures
• are energy saving
• better protect the engine from wear
• higher low temperature viscosity
• longer service life

Semi-synthetic oil is intermediate between mineral and synthetic oil, both in terms of properties and in terms of the proportion of the main components.
If the winter temperature does not drop below -25C degrees, then the use of synthetic oils only because of low-temperature viscosity is not advisable.
It is not recommended to use synthetic oils in Lanos cars with increased mileage, when there is a possibility of oil losses and leaks.

Original oil for Lanos
The simplest and most correct way to select oil for a Daewoo Lanos lies in the direction of choosing the original oil recommended by the manufacturer.

IN Daewoo cars Lanos is equipped with Opel engines, which were developed and manufactured by General Motors. Designed specifically for these engines GM motor oil , which was poured on the assembly line. Original GM oil can be purchased in our online store.	The second recommended for use in Lanos cars is the Belgian WOLF oil. A special feature of this oil is that it was developed jointly with GM and for GM vehicles. Corresponds to a high quality class for semi-synthetic oils. WOLF 10w-40 oil can be purchased in our online store.

What oils are poured into Lanos

The top selling oils for Lanos are Castrol Magnatec oil. To be fair, it should be noted that Castrol is more often used in Daewoo Sens cars. This is partly due to the presence of special molecules in the oil that provide additional protection to the engine, as well as good experience with use in higher-class cars. Castrol Magnatec oil from a German plant can be purchased in our online store.

Lanos enjoys stable demand among motor oils English oil COMMA . COMMA Eurolite is a premium oil manufactured at a factory in England. A special feature of this oil is the absence of components recovered from used oil, which are officially added by many European manufacturers to reduce the cost of their products. COMMA oils are 100% virgin oils! Poured into many racing cars. COMMA oil can be purchased in our online store.

I would like to recommend buying a Lanos or Sens to every car owner best oil, do not skimp on things that prolong the life of the motor. Check the oil level regularly. Change the oil in a timely manner. Do the right purchases- choose the best.

Does changing the oil in a Daewoo Sens coincide with replacing the timing belt? Choose

In order to choose the right type of motor oil for your engine, you need to carefully examine and weigh everything. Although the Chevrolet Lanos is not something special, it is necessary to treat special attention to his needs.

What affects the time for changing engine oil on a Chevrolet Lanos

Under the hood of Lanos.

This is the most important factor that affects the performance of the car. Experts say that the oil should be changed between from 8,000 to 15,000 kilometers . Such a large run-up is explained by objective factors, such as:

• The quality of the originally filled oil;
• Fuel quality;
• Driver's driving style;
• Operating conditions of the vehicle.

Users have their own opinions about the replacement

Oil filler neck.

Car enthusiasts claim that the limit is 5,000 or 7,000 kilometers is objectively the most suitable for Lanos. In any case, if the oil has a characteristic dark dirty color, it is a sure sign that it is time to change it.

No kilometers or distances will be of exceptional decisive importance. The most important thing is the condition of the lubricating element. Before you start replacing, it would be good to decide on the volume.

How much oil do you need to buy to change?

Kit for oil change on Lanos + flushing fluid. There is a lot of controversy about its use.

According to the manufacturer's specifications, the engine contains 3.8 liters. The figure does not depend on the engine size; all options require the same amount.

This means that by purchasing a four-liter canister, pouring the required amount, you can get a balance of 200 grams for future refilling.

In fact, car enthusiasts talk about certain inconsistencies. If you make a replacement and first pour a little oil into the filter before starting work, you will get a fundamentally different result from the standard one. 3.8 liters on the dipstick will indicate middle position.

The optimal amount for an oil change is about 3.8 liters.

If you pour everything 4 liters, then on a warm car it will be just max. It turns out that there will be nothing left for refilling. You will need to buy a little more, or in a 4.5-5 liter canister. That's the math.

The insides of the engine on Lanos, into which only good oil and changed it strictly according to the regulations.

Classification is provided according to the following division principles:

• viscosity grade (SAE term);
• operational properties (quality class);
• manufacturer's approval.

Definition of Viscosity Term

Viscosity implies certain properties of ductility when changing temperature regime inside the combustion chamber and the external environment.

At low temperatures, the viscosity should be lower, and at high temperatures, vice versa.

This is vital not only to be able to start the engine, but also to maintain pressure in the system. It is extremely important that lubricant reaches all rubbing surfaces on time and without difficulty.

Types of viscosity values

• Winter help to start the car even at extremely low temperatures.
• Summer Due to their high viscosity, options are simply necessary in the heat.
• All-season are a universal method for any time of year.

The vehicle documentation contains the following SAE indicators:

• 5W - 40;
• 10W - 40;
• 15W - 40.

Quality classes are represented by the following indicators

• API SJ;
• ACEA A1;
• ACEA A2;
• ACEA A3.

You can also use any other one whose quality characteristics are higher than those recommended.

List of options approved by the manufacturer for use

• Opel GM - LL - A - 025;
• Opel GM 5W - 30;
• Opel GM 5W - 30.

There are other analogues that may be acceptable. These include the ELF brand with modifications GM 5W-30 or 0W-30. Additionally, Mobil 1 is recommended for use, among which 0W-40 and Shell 5W-30 can be distinguished. Castrol oil 0W-30 can also be safely filled in.

We consider semi-synthetic oil to be optimal for Lanos. You can choose the manufacturer yourself!

When selecting a suitable lubricating fluid, it is best to follow the recommendations made by the manufacturer. Today there are the following principles that characterize oil according to another important indicator.

The composition of base elements, additives, and other components is divided as follows:

• Mineral - the result of oil distillation, in which the viscosity directly depends on the temperature conditions of use. In this set, although special additives are used, they are quickly destroyed due to high temperatures and mechanical overloads. The service life of these types is quite short.
• Synthetic – synthesized using chemical processes. The consistency is quite homogeneous, the properties are stable, they do not lose their viscosity and fluidity in extreme cold. They become more viscous in the hot season, do not fade as much as mineral ones, and form less precipitation. They last quite a long time.

An important advantage over other types – non-aggressive, does not corrode oil seals, however, they can leak at the site of worn seals due to increased fluidity.

• Semi-synthetic - average option. Mineral ones last longer, but are less durable compared to synthetic ones. Rapid darkening indicates contamination of the system, as well as good cleaning properties of these types of lubricants.

In the case when the oil does not burn out much, it is better not to experiment with choosing new brands, or those that have special properties. If you regularly have to top up the dipstick to the average level, then it’s time to think about replacing.

With age, the connections in the car become less tight, so with a significant mileage, users recommend switching from synthetics to semi-synthetics. Cars whose engines are quite tired can even expect mineral lubrication.

Choosing the right engine oil is one of the fundamental factors for the normal operation of a car. The classification of oils has three divisions according to viscosity grade (SAE) and two according to performance properties. SAE classification implies one or another viscosity of motor oil. This is a very important factor that directly affects the operation of the car.
According to experts, the oil needs to be changed every 8-15 thousand kilometers. In other words, changing the oil once a year ensures normal vehicle operation. Many car enthusiasts who use Chevrolet Lanos (aka Daewoo Lanos in Ukraine) have a different opinion and claim in their reviews that the oil should be changed every 5-7 thousand kilometers of the car.
Be that as it may, one thing unites all car enthusiasts - doubts whether the time has come to change the brand of motor oil, choose oil with a different viscosity, etc. According to reviews, if a car requires constant topping up of oil, this indicates that it is overused, and it is necessary to choose a different manufacturer or class of oil. The Chevrolet (Daewoo) Lanos operating manual states that oils with the following quality classifications are allowed for use in the engine:
- API SJ
- ACEA A1/A2/A3 or higher.
Required viscosity:
- SAE 5W-40
- SAE 10W-40
- SAE 15W-40, etc.
Engine manufacturer approval:
- Opel GM-LL-A-025
