Which oil is better to pour into a Daewoo Nexia 16 valve box?

What determines the performance of the Daewoo Nexia’s internal combustion engine and gearbox? From fuel, preferably of good quality, and from engine and transmission oil poured into components and assemblies. To extend the service life of the car, you need to choose oils for the Daewoo Nexia engine and gearbox not based on price, but on characteristics.

Which oil is better to choose

When changing the oil in a Daewoo Nexia n150 gearbox with 8 or 16 valves, you need to know what kind of lubricant should be poured into the system. The manufacturer does not regulate this replacement. Accordingly, you will not be able to find information about choosing a product in the service book. Practice shows that Daewoo Nexia gearboxes whose owners fill with synthetic or semi-synthetic lubricant last a long time. Initially, when a car is manufactured, mineral oil is used in the gearbox, so when buying a car it is also better to change it to “synthetic” or “semi-synthetic”.

If the climate in your region is moderate, then you can safely use any oil of the SAE 80W GL-4 standard. When operating a car in severe frost conditions, it is better to give preference to the 75W90 GL-4, proven by car enthusiasts. This lubricant is especially suitable for northern regions, where the average air temperature throughout the year is −25 degrees. It is possible to use both synthetic and semi-synthetic oils, but for cold climates “synthetics” are better suited. The use of such fluid in the warm season can lead to noise in the transmission.

Engine oil

Despite the fact that several engines were installed in the Nexia - 8kl and 16kl, with a volume of 1.5 and 1.6 liters, the engine oil will be the same in all cases. Everything will depend on the preferences of the car owner.

Now let’s figure out which oil is better to fill in Nexia. To do this you need to answer some questions.

Oils are divided into mineral, semi-synthetic and synthetic.

• Mineral oil, such as oil, should not be poured into the Nexia engine, as it has the worst service life and the lowest quality of lubrication. With such oil, the engine will quickly overheat, under load it can get scuffed, and after use the oil leaves a residue in the form of carbon deposits.
• Semi-synthetic oil, standard oil suitable for the engine. This oil should be poured into the car engine. Much cheaper than synthetic oil.
• Synthetic oil should only be filled up to 100 thousand kilometers. This is due to the fact that synthetic oil is very fluid, and from a used engine, oil can ooze out of the seals and other holes.

So, in Nexia it is necessary to fill in subsoil oil with a class not lower than SG/CC - this is the standard class into which all oils are divided. You shouldn’t bother with the letter value, the main thing is that the label says it’s for gasoline engines (four-stroke). Class SG/CC - written, for example, on Lukoil mineral oil. Since it is absolutely not worth pouring mineral oil into Nexia, any semi-synthetic oil will, by definition, be of a higher class, and therefore meet the requirements.

Next, you should know what the numbers on the canister of 5W-40 oil, etc. mean. These inscriptions indicate the temperature range of oil operation. For example, in winter you should fill in one type of oil, and in summer another. You can understand this choice thanks to this table:

Oil viscosity table

The established volume of oil filling into the engine is 3.75 - 3.8 liters. Canisters are sold in 4 liters, this is enough for you to change the oil, as well as top up while using the car.

The oil viscosity should be selected carefully. A visual table showing how fluidity changes at low temperatures.

What brands of oil are most often poured into Nexia?

The manufacturer and dealers most often fill in Mobil brand semi-synthetic oil; the viscosity depends on the region where the vehicle is used.

Most often there are lovers of the Shell brand who fill in semi-synthetics. There is no definite answer to this question, since everyone chooses oil to suit their wallet. The price for a 4-liter canister starts at 1,200 rubles, but can cost more. The most inexpensive oil is Lukoil, which car enthusiasts do not recommend pouring into the engine. According to Nexiyavodov, this oil leaves carbon deposits and also quickly loses its lubricating properties.

You can use original GM oil, but it will cost many times more. Canisters under this name are filled with completely ordinary oils - be it Total, Mobil, etc.

How much do you need to fill?

It is equally important for owners of these car models to know how many liters are poured into the transmission. Service books for cars that require replacement of this consumable usually contain a table with fill parameters. In the case of an 8- or 16-valve Nexia, there is no such information in the service manual. However, before changing, you need to consider how much lubricant to pour into the gearbox.

As for volume, the transmission of the Daewoo Nexia should contain about 1.8 liters of oil.

History of Nexia

This Korean middle-class car was presented to the public in 1986. The development was carried out by German specialists (). The car was created on the basis of the Opel Kadett E, which was widespread at that time. "Nexia" began to be produced for residents of developing countries. Since 1995, cars have become available to citizens of the former Soviet Union. By the way, this car is known to Korean residents under the name “Daewoo Cielo”.

Ergonomics of Daewoo Nexia

The car stood out, first of all, for its low price. It cost no more than Russian front-wheel drive VAZs. The car was quite reliable, unpretentious in use, was ahead of Russian cars in terms of these characteristics and was not inferior to imported middle-class models. Replacing broken parts was easy due to their availability. All this explains the ubiquity of this machine.

However, Nexia gradually began to lose ground. The last car of this model was released four years ago. After this, the Korean manufacturer began producing the Daewoo Gentra.

Consequences of untimely replacement

8- and 16-valve Daewoo Nexia requires periodic replacement of transmission oil, since the additive package in the lubricant loses its properties over time. As a result, it becomes inoperable. Because of this, the liquid cannot provide the proper level of protection for rubbing surfaces. The loss of basic properties will lead to foaming of the working substance, which will ultimately cause scuffing of the main gear. As a result, the gears of the transmission differential will begin to hum, that is, the operation of the gearbox will be accompanied by a hum.

After 500-1000 km, the teeth on the gears will be destroyed. And this will lead to the transmission jamming. The driver will not be able to engage one or more gears. In Nexias with automatic transmissions, oil is also used to cool the unit. Failure to change the lubricant in a timely manner will result in kicks and jolts when shifting gears.

How often does an oil change need to be made?

To begin with, we suggest you sort out the question of when to change and fill new fluid into a manual transmission of a Daewoo Nexia 150 2011 or another year of manufacture. According to official data from the automobile manufacturer, the oil initially poured into the transmission at the factory must be used throughout the entire life of the vehicle. But the manufacturer also does not specify what the specific service life of the car should be. Therefore, the car owner will not be able to check whether this resource has expired or not.

In order to prevent serious malfunctions in the operation of the Daewoo Nexia gearbox and avoid large financial costs, it is recommended to change the transmission oil after 100-150 thousand kilometers. Or every 7-10 years. If there are malfunctions in the operation of the unit or difficulties with switching speeds, the fluid can be changed earlier. The best option is to replace it every 100 thousand kilometers.

How to change the lubricant yourself?

You can replace the working fluid with the help of specialists at a service station or yourself. Let's look at the process of changing it yourself.

Preparation

Before completing a task, you need to prepare. Buy two liters of lubricant and prepare the tools:

• a set of wrenches or socket heads (you will need tools for 13, 17 and 19);
• jack;
• medical or construction syringe;
• new transmission pan gasket;
• an old bucket, basin or cut-off bottle for collecting waste.

Before purchasing a gasket, be sure to inspect the pan on the transmission. On sale you can find two types of pallet gaskets, which are mounted with 10 or 11 bolts. Therefore, when buying a seal, make sure that it suits you. If it is not possible to purchase a gasket, you can make it yourself from paronite. As a last resort, if there is no seal, the perimeter of the pan must be coated with sealant.

The best motor oil. does it exist?

• used oil loses its original composition, loses its lubricating properties and additives
• The viscosity level is significantly reduced, the oil foams and oil starvation occurs, as a result of which the rubbing parts of the manual transmission are subject to accelerated wear, and scuffing appears on the gearbox gears

To avoid the above problems, you must promptly:

• checking the fluid level. This must be done when the gearbox has cooled down every 8-10 thousand km. The fluid should be level with the bottom edge of the filler hole.
• checking the gearbox housing for the presence or absence of damage, oil leaks, etc. If leaks are detected, you must contact a diagnostic service
• analysis of oil by color, smell and content. The liquid should not have a cloudy color, there should be no sediment or metal particles in it. You should also pay attention to whether the oil is cloudy, dark, or clear in color.

Level control and topping up

Before changing the lubricant, you need to make sure that its level is normal. If the check shows a critical lack of fluid, you need to carefully inspect the unit for leaks. Visually assess the condition of the transmission - the gearbox should not have cracks or other signs of leaks. Otherwise, the problem must be solved.

Visually familiarize yourself with the process of replacing transmission fluid in a Daewoo Nexia car in the video (author - Alexandr Borziy).

To diagnose the oil level, do the following:

1. Place the front left side of the car on a jack. The inspection hole is located in an inconvenient place. You can try to get to it from under the hood, but it is more difficult.
2. Unscrew the left wheel, if you look in the direction of travel of the car. A wheel wrench is used to unscrew the bolts.
3. After dismantling, next to the CV joint (constant velocity joint), you will be able to see a plug in the form of a bolt. You need to unscrew it with a wrench.
4. If the fluid level is normal, then after unscrewing the plug you will see grease near the lower hole.
