Daewoo Nexia is a compact B-class car, first introduced in 1994. It is a platform version of the 1984 Opel Kadett E, which, in turn, is a clone of Nexia’s predecessor – Daewoo Racer 1986-1994. Thus, Nexia is only a modified version of Racer. Despite the outdated design, the car was in steady demand until 2016. The car was produced in Uzbekistan and Russia. The 2008 modernization slightly refreshed the appearance of Nexia, but there were no technical changes, except for the modified engine range. By that time, the car also received a top-end 1.6-liter engine with 106 hp. s., familiar from Chevrolet Lacetti.

What kind of oil should I put in the Daewoo Nexia engine?

The small-class car Daewoo Nexia became, in fact, the first foreign car that domestic car enthusiasts began to purchase en masse.
The model was developed by Opel specialists and later modernized by specialists from the Korean company Daewoo. The car began to be produced in 1996 and until 2016 two generations were produced. For some time, cars were assembled in Rostov, but mostly assembly took place in Uzbekistan. Over the entire history of its existence, about 500 thousand copies of the model were produced; Daewoo Nexia was purchased not only in Russia, but also in other countries of the post-Soviet space. In 2008, a restyling was carried out, during which engines that did not meet the requirements of Euro-3 environmental standards were replaced; instead of the outdated G15MF and A15MF, a new A15SMS with a power of 80 hp appeared. With. Motor oils are classified by the American Petroleum Institute based on their quality level. Each quality category is designated by two letters. The first letter indicates the type of engine for which the lubricant is characterized. The second letter respectively indicates the quality level of the lubricant. It is allowed to use lubricants of higher quality without regard to the manufacturer's recommendations.

Engine oil for Daewoo Nexia should be:

• API SJ or higher for Daewoo Nexia;

As for specific brands, there is no information about this in the manual. The car manufacturer does not bind the motorist to a specific brand of product. Therefore, in this regard there is complete freedom of choice.

Useful tips

When unscrewing the drain filter, make sure that the sleeves of your clothing are long enough. This will prevent your skin from coming into contact with the exhaust manifold screen.

When removing the lubricant filter from above, you must prepare a piece of rag in advance and spread it under the filter on the crankcase protection. In this case, the oil that will flow out of the filter will not spread over the protection. So the driver will be able to draw the right conclusions regarding the tightness of the system.

If you don't currently have a new copper sealing washer, you can use an old one. Only it will need to be treated with fine sandpaper until a smooth surface is obtained. However, it is not recommended to use an old washer more than twice. Don't be afraid to keep the lubricant level as high as possible.

How much oil is in the Daewoo Nexia engine

You can change the engine oil and filter yourself. To do this job, you need to know the filling volumes. The filling volumes of Daewoo Nexia power units are (including the oil filter):

• A15SMS - 3.8 l;
• F16D3 - 4 l;
• G15MF - 3.9 l;
• A15MF- 3.9 l.

Advice: we recommend keeping a few liters of material in reserve in order to, if necessary, replenish the missing amount of lubricant in the system.

Tools

• new oil;
• a new filter element, better a unique one, as annoying as it may sound, clear filters from other companies are listed;
• drain plug o-ring;
• filter remover (you will need it if you can’t unscrew it by hand);

Filter wrench

• a capacity of approximately 5 liters for draining waste water; it is made from a plastic bottle or canister. How much oil is in the MAZ 504 engine? Be sure to wash it, as later you can really evaluate the quality of the used oil;
• gloves, since during such work, waste oil can flow into your hands, which is very harmful to the skin;
• a set of keys;
• screwdriver;
• a funnel made of any material for which the design is intended, rolled up from thick paper;
• rags.

What is poured into the Daewoo Nexia engine from the factory: recommendations

The brand that produced the motor oil for Nexia was not particularly advertised. The factory poured in what was supplied to one or another assembly plant. Still, there are certain parameters regulated by the manufacturer that influence the choice of lubricant for the engine. The plant strongly recommends that you comply with the minimum requirements for engine oil when purchasing.

In particular, this concerns viscosity. However, the viscosity of the oil, which we dealt with not so long ago, is selected individually and is determined depending on climatic conditions and, of course, the operating mode of the engine. Here's what the manufacturer says:

1. It is highly not recommended to use mineral-based motor oils. Preference should be given to synthetic and semi-synthetic products.
2. Based on the API standard, the oil must meet the requirements of the SM/SF class.
3. The viscosity of the oil depends on the ambient temperature. SAE 5W-30 should be used when the temperature drops below -20 ˚С.
4. Oils 5W-40 or 5W-50 are poured in the average climate zone.
5. At high temperatures, in the south or in hot summers, use oils 10W-40, 10W-50.

Modifications

To eliminate the above errors, it was decided to improve the engine. Extensive work was carried out, the gas distribution phase adjustment unit was updated, and automatic valve regulators were replaced with a calibrated version.

Another modification of the F18D4, unlike its predecessors, has more power. This was achieved by increasing the volume of the cylinders. It was also possible to increase the timing belt life by 50%. Another useful innovation was the replacement of the working parts of the valves with products made of soft but corrosion-resistant metals.

What kind of oil to pour into the Daewoo Nexia engine

Oil quality is the main selection criterion. In no other European country are there as many counterfeits as in Ukraine, and this must be clearly understood. Any genuine oil that meets the parameters specified above is suitable for use.

Moreover, even high-quality modern mineral oils can be safely used in the summer - there will be no leaks, no drop in pressure, guaranteed by experience. And mineral oils are much cheaper than synthetics. But provided that the mineral water is of high quality. Yes, and you should not forget to flush the lubrication system after using synthetics or semi-synthetics.

Semi-synthetic motor oils are perfect for engines with high mileage. The fact is that synthetic oil in a dead engine will help like a poultice for a dead one. It will instantly find a leaking oil, the pressure will be unstable, and besides, you will have to spend a lot of money on topping up the already expensive synthetics.

Sequence of work

1. We provide access to the filler neck, which is located in the engine compartment. We unscrew the plug. New oil will be added later
2. We climb under the car, remove the engine protection, if any.
3. We place a technical container under the drain hole, then unscrew the plug and observe the process of the old liquid flowing out. It is possible that the oil will come out along with dirt, soot and metal shavings. You need to work carefully here, as the oil is very hot. It is advisable to wear gloves and protect your face with some kind of mask. This will prevent hot oil from splashing into unwanted areas.
4. After draining the liquid, tighten the plug tightly and move on to the next step.
5. We provide access to the oil filter, which will have to be pulled out and then a new element inserted in its place. Before doing this, you need to thoroughly wash the seat under the filter. Lubricate the new O-ring with oil, and also pour some fresh oil into the new filter, then install it in its seat. You can do this by hand. When using the tool, you must act carefully so as not to damage the thread.
6. After making sure that the new filter and drain plug are tightly screwed on, we come out from under the bottom of the car and take a new lubricant
7. New oil should be poured into the hole through a funnel, and this should be done smoothly, avoiding sudden movements. Please note that you need to fill in a certain amount of liquid - exactly as much as the old oil was drained
8. After bringing the amount of oil to the optimal level (between the Max and Min marks on the dipstick), we put back all the removed parts, including the filler plug.
9. Let's start the engine. It should run for a few minutes. At this moment the oil pressure light will come on. If it goes out, this means that the fluid replacement process was successful. Otherwise, we turn off the engine and urgently find out where the possible malfunction is coming from.
10. After making sure that the oil level is normal and the light has gone out, we take a test drive around the city. After 10-15 kilometers, we check the fluid level again and top up if necessary.

Brands of engine oils for Daewoo Nexia

The brand of engine oil for the Daewoo Nexia is a matter of the owner’s religious affiliation. You will never be able to convince someone who is on Castrol to fill up with Shell. Not because it's better. He is so used to it and it seems to him that Castrol copes perfectly with engine lubrication and he is, of course, right.

In a word, here are several popular brands of motor oils that are most often used by Daewoo Nexia owners and that meet the manufacturer’s requirements:

• Shell Helix HX8 5W-40;
• Zic 5W30;
• GT Turbo Coat 10W-40;
• Castrol SLX Professional 5w-30
• Mobil 10W-40;
• Mobil 5W-40;
• Eneos 5W-40;
• 5w30 from GM;
• ELF Competition;
• Esso 5W-40.
• Liqui Moli Synthoil Energy 0W-40.

To summarize, we note that the schedule for changing Daewoo Nexia engine oil at 10 thousand km does not correspond to our operating conditions, so we are reducing it. We choose the brand of oil at our discretion, but beware of counterfeits.

Any good synthetic or semi-synthetic oil with a viscosity of 5W-30, 5W-40, 10W-40, 10W-50, 5W-50 is approved by the manufacturer. And yet, we try not to use magic additives that magically extend the life of the engine indefinitely. Miracles don't happen, but that's a completely different story.

Leaks and problems

The longer the mileage of the Daewoo Nexia becomes, 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.

If, when inspecting the engine for leaks, they are found, then eliminating the leak, and with it the burns, is not difficult. But if there are no signs of leakage, then you should pay attention to the following nuances. Increased oil consumption can be affected by driving at high speeds, as well as frequent idling of the engine.

On 16 valve engines there is a common problem, oil in the spark plug wells. The reason for this lies in the valve cover gasket. The covers themselves come in plastic and aluminum.

Therefore, in order not to make a mistake, owners are advised to choose not the original, but the analogue Victor Reinz 15-53456-01 (155345601), this gasket is suitable for any type. You will also need o-rings for the bolts. Here you can save money and buy from Kamaz, article number 7401003040. And of course, don’t forget to buy sealant for the gasket. And also a cleaner for cleaning oil from the seating surface.

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.

Daewoo Nexia engine oil - how often to change

The car manufacturer Daewoo Nexia recommends changing the oil every 10 thousand km. Under favorable conditions, detergent additives, as a rule, lose their effectiveness closer to 7-8 thousand km. However, in the worst case, an oil change may be needed every 6 thousand km if the engine is overloaded due to constant exposure to city traffic jams. Under these conditions, sudden throttle changes and braking, frequent gear changes, unpredictable driving style, etc. are possible. All this leads to overheating of the internal combustion engine and premature deterioration of oil quality.

Daewoo Nexia engine - how much oil to fill

First generation N100-N150 (1994-2016)

In terms of design, the Daewoo Nexia was in many ways similar to its ancestor, the Kadett. However, the appearance of the Korean car has been improved by adding streamlined shapes, resulting in much less angular lines. However, inside the Nexia even more evoked associations with cars from the 80s. In addition to hard plastic and cheap finishing materials, many owners spoke negatively about the specific driving position, and passengers spoke negatively about the cramped interior in the rear. But the car received a spacious trunk - one of the most voluminous in the class. In addition, Nexia was perfectly adapted to Russian road conditions. In terms of safety, not everything is clear - the car withstood the first crash test of Autoreview (a collision with a hard half barrier at 50 km/h), but in more stringent tests (the second crash test of Autoreview with an impact of 64 km/h with a 40 percent overlap) turned out to be a failure for Nexia.

Any engine oil with suitable characteristics will be suitable for Daewoo Nexia car engines. You should choose from proven brands Kixx, Shell, Valvoline, Mannol, Shell, Castrol, Liqui Moly, etc. You can also opt for relatively inexpensive domestic products Rosneft, G-Energy and Lukoil. As for the SAE viscosity type, in this case climatic conditions must also be taken into account. For example, for winter use viscosities 0W-30, 0W-40 and 5W-40 are suitable, and in summer it is recommended to use 20W-40 or 25W-50. If we are talking about all-season use, then you can stop at SAE 10W-40 or 5W-30.

Unoriginal

When choosing high-quality engine oil for Daewoo Nexia, you must also take into account the API approval, which characterizes the quality and compatibility of the product. For example, for cars of earlier years (for example, 2008), all-season semi-synthetics with a viscosity of 10W-40 and API-SL approval are recommended. If we are talking about more recent cars produced in 2014, then you can opt for pure synthetics with API-SM approval. Below are the best lubricants for Daewoo Nexia engines.

• Shell Helix HX8 5W-40
• ZIC 5w-30
• Eneos 5W-40
