What kind of oil to fill in the Kia Rio X Line engine

Kia Rio 4 is a Korean B-class car, the best-selling Kia model on the Russian market. The car entered production in 2017, and its Russian version is produced in St. Petersburg. The car is available in hatchback and sedan bodies, and also has a new design compared to its predecessor, despite its similar design. Technically, the Rio is similar to the platform model of the Hyundai Solaris of both generations.

Since 2021, a restyled version of Rio has been produced, which has an updated design, an improved media system with a larger diagonal and an expanded set of options. The engine range includes gasoline engines of 1.4 (100 hp) and 1.6 liters (122 hp), operating with a six-speed manual or automatic transmission. Based on the 4th generation Rio, a cross-version of the Rio X-Line was created, which is distinguished by increased ground clearance (+10 mm), modified suspension and protective plastic body kits around the perimeter of the body.

When to change oil in 4th generation

You can decide when to change the oil based on the condition of the engine and signs indicating the need for replacement. Unpredictable regulations are especially relevant in cases where the operating mode of the vehicle differs significantly from the statistical average. For example, unscheduled replacement cannot be avoided in the following cases:

  • frequent long-distance travel
  • commercial use
  • mileage exceeds 150 thousand km
  • The engine is subject to constant stress due to towing trailers or off-road driving

When do you need to change the lubricant in the engine more often than recommended?

Conditions considered severe by the manufacturer are:

  1. frequent driving on dusty, uneven or congested roads;
  2. regular short trips (up to 16 km at low temperatures, up to 8 km at normal temperatures);
  3. long-term operation of the internal combustion engine at idle speed;
  4. frequent driving on sections of roads heavily treated with salt;
  5. use of a trailer, frequent towing of other cars;
  6. operation as a taxi, patrol car;
  7. driving in mountainous areas (with frequent descents and ascents).

If the Kia Rio is operated in such conditions, then the frequency of oil changes should be halved. Regular replacement will preserve the life of gasoline internal combustion engines installed on Korean cars.

Recommended replacement schedule

The frequency of oil changes often depends not only on operating conditions, but also on the design of the engine. This is due to the fact that automakers can introduce certain maintenance regulations for a certain type of internal combustion engine. However, even in this case, the replacement time falls within the range of 10-15 thousand kilometers. Of course, due to possible heavy loads, it will be necessary to deviate from this regulation and perform the replacement earlier than the stated deadline.

Features of oil consumption in various conditions

With a mileage of over 150 thousand km, engines already have a certain degree of wear, but under favorable conditions this does not cause accelerated clogging of the oil and a deterioration in its viscosity. However, in difficult conditions, the life of such an engine will inevitably come to an end, which is why excessive oil consumption is possible: its quality will deteriorate and the level will decrease. Based on this, in addition to factory regulations, it is equally important to take into account operating conditions:

If in the city the oil service life can reach 600 hours, then on the highway this figure will be 250 hours
At speeds up to 130 km/h, nothing bad happens to the oil, since this is an absolutely acceptable speed limit for a modern car. However, if you constantly exceed this speed (constant trips on the highway at speeds above 130 km/h), then in this case the technical fluid has a high degree of wear. Here you can also add negative factors such as heat and frost, which worsen the condition of the lubricant. The same applies to extreme driving in city traffic jams, or active off-road use: driving on sand, snow, mud and frequent slipping. In such conditions, the vehicle’s components work to the limit, which inevitably leads to a reduction in maintenance schedules.
The oil change period is also affected by the condition of the fuel. A low-quality fuel mixture with a high sulfur content causes rapid oxidation of the oil and a sharp deterioration in its lubricating properties.

Oil change period depending on oil type and engine

For gasoline engines

  • Synthetics - 10-12 thousand km
  • Semi-synthetics - 8-12 thousand km
  • Mineralka – 3-5 thousand km

Functions of oil and why it is important to change oil on time

The need for timely oil changes is obvious, since a high-quality lubricant has three important functions on which the performance and durability of the engine depends.

1. Heat removal from heated components . Unlike a radiator with antifreeze, engine oil has a much more important task - namely, cooling in specific friction areas of parts
2. Anti-corrosion protection . This function of the oil is extremely important under conditions of temperature changes and increased loads, which can cause mechanical damage, as well as oxidation and corrosion processes. Protection against them is provided by a durable oil film that envelops the internal combustion engine parts and thereby protects them from rust.
3. The cleaning function of oil plays an important role in keeping the engine clean. Oil has the ability to collect and retain carbon deposits, metal particles, dust and soot. This prevents scratches and other damage on rubbing surfaces.

Consequences of untimely oil changes

Based on the above, you can be sure that poor or low-quality oil does more harm than good for the engine. With high mileage, the beneficial properties of the oil deteriorate. In this case, large elements of wear products settle on the oil filter, while small fractions continue to circulate along with the oil along the highways, and thus contamination occurs. As a result, whistling, knocking and other extraneous sounds appear. Serious consequences of untimely replacement include cranking of connecting rod bearings, engine oil starvation, jamming of the camshaft, bent valves and sticking of piston rings. All this leads to a major overhaul of the engine.

How to determine oil aging

To check the condition of the oil, do the following:

  1. Warm up the engine
  2. Pull out the dipstick and drop a little oil on the paper
  3. Determine the condition of the oil by the color of the drop: - clear oil indicates a high concentration of water - light brown oil indicates a small amount of harmful deposits - dark brown color is a sign of a large accumulation of wear products - a black drop indicates that the oil has long been outdated and it needs to be changed urgently

Tips for changing oil in difficult conditions

  • An early oil change is necessary in such extreme situations: - frequent off-road driving - staying in traffic jams - driving with semi-trailers and other heavy loads - sudden starts and braking
  • For severe conditions, you should choose a high-quality branded oil that has sustainable beneficial properties
  • With frequent vehicle downtime, condensation forms inside the engine, which leads to a change in the chemical composition of the lubricant. As a result, things can lead to corrosion of parts and serious problems with the internal combustion engine.
  • Under heavy loads, it is important to prevent the engine from overheating in order to increase the oil change schedule and increase the service life of the internal combustion engine.
  • Changing engine oil is carried out only on a warm engine
  • High-quality oil must meet all factory requirements

Lubricant for Kia Rio 1st generation

Kia Rio 1 cars are equipped with 1.3 A3E and 1.5 A5E engines. The lubrication system of the first power unit must be filled with 3.3 liters of oil when replacing it. The 1.5 liter engine is a little larger – 3.4 liters.

The replacement interval is regulated; the oil needs to be updated every 10-15 thousand kilometers.

Answering the question of what kind of oil to pour into first-generation power units, it is worth noting that synthetics behave better throughout the year. Semi-synthetic oil with a viscosity of 10w-40 is used less often. The viscosity of synthetic motor oil is 5w30 or 5w40.

The list of motor oils most often used by car owners includes the following brands: Zic, Motul, Mobil, Castrol, Shell Helix.

What oil is better to pour into the engine?

For Kia Rio 4, two types of oil should be considered:

Semi-synthetic - designated as Semi-Synthetic and is a mineral oil with the addition of a small amount of synthetics, which slightly improves the basic properties of mineral oil. On the one hand, a liquid of this type can be equated to full-fledged synthetics, provided that we are talking about world-famous products. On the other hand, you need to understand that even the highest quality and most expensive semi-synthetics will not replace full-fledged synthetics

Synthetic is the best type of oil today. Therefore, owners of modern cars such as the Kia Rio 4 choose synthetics. This liquid is suitable for hot and frosty climates, since it is able to maintain its liquid consistency at any time of the year, while semi-synthetics are prone to freezing at extremely low temperatures. Moreover, synthetics best protect the engine from oxidative and corrosive effects, thoroughly clean all engine surfaces and prevent the formation of harmful deposits.

What groups of oils are there?

Summer oil - suitable only for operation in conditions with positive ambient temperatures. At low temperatures, the use of such oil can cause problems with starting the internal combustion engine, since summer fluid can thicken and freeze

Winter oil is the exact opposite of summer lubricant. On the contrary, such a liquid has a rare consistency and is not prone to freezing, which allows it to be used at extremely low temperatures. However, in hot conditions, winter oil becomes even thinner, which can be critical for cars with high mileage. For example, if microcracks are present, leaks may occur. In addition, even in summer conditions, such oil is not capable of forming a strong oil film to protect parts from dry friction and various damages.

All-season oil is most relevant for the Kia Rio 4 if the car is operated in Russian conditions with a variable climate. This liquid is not specialized, and therefore is suitable for any time of year. Therefore, all-season liquid is universal and easy to use.


The best lubricants for Kia Rio 4 can be identified depending on the type of oil:


Shell Helix HX7 5w-30

Liqui Moly Molygen New Generation 5W-20

Motul 6100 Save-lite 5W-20


Shell Helix Ultra Professional AM-L 5W-30 Total Quartz 9000 Future EcoB 5W-20 Castrol Magnatec Professional E 5W-20 Liqui Moly Synthoil High Tec 5W-30 Motul Specific 948B 5W-20

Choosing oil for Kia Rio: tips and tricks

The topic of choosing oil for Kia Rio is extensive. The entire model range of Korean cars is equipped with very reliable engines. However, if you do not carry out the required maintenance, without timely diagnostics, any, even the most reliable motor will begin to fail.

Regular oil changes in Kia Rio are one of the important stages in car maintenance. This is especially true for those cars that have already been in use for some time. The engine receives a serious load, and therefore suffers from premature wear without proper care.

The frequency of oil changes depends on the manufacturer's recommendations. To prevent wear and tear, the manufacturer recommends replacing the product at least every 10,000 km.

About three liters of liquid are poured into the engine. The obvious fact is that the oil needs to be changed promptly and regularly.

The main indicator for deciding whether an oil change is needed is its viscosity or degree of fluidity.

For Kia Rio engines, the manufacturer recommends oils with a viscosity of 5W-30 or 5W-20. Moreover, the latter option is more preferable for KIA, which are operated in Russia.

At the same time as the oil, service centers always change the oil filter. If you decide to carry out the replacement procedure yourself, take into account some of the features of Kia Rio engines of different years of manufacture.

For example, for cars of 2015, 2012, 2013, 2014, you can select several suitable options:

  • Shell Helix Ultra;
  • Total Quartz;
  • Divinol;
  • ZIC XQ LS.

Price-quality analysis shows that the best option among those presented is Shell Helix Ultra . The branded product includes the entire range of additives and minerals. Using it for the Korean Rio is quite justified. Shell does not lose its positive qualities with prolonged active use, which is also a definite plus for the oil of this company.

Total Quartz boasts impressive characteristics. This oil is also capable of keeping all engine parts in working condition. The price of a branded product is also not high. The original characteristics of the additives and minerals included in the oil retain their qualities even during long-term active use of the vehicle.

Divinol oil differs from previous ones in low consumption. Despite the fact that the brand has not received widespread advertising in the media, it is actively purchased by knowledgeable motorists. The option is quite suitable for KIA, as it copes with all engine protection functions.

ZIC oil is another product that is sold at an affordable price. The impressive list of additives included in its composition may alarm some. However, they directly affect the protection of the motor from premature wear. It can be safely poured into the Rio engine.

If we consider the choice of oil from the point of view of choosing a brand, then this exercise is practically useless. Each car owner has his own preferences. It is unlikely that anyone will want to change the brand just after reading one article.

Moreover, the Rio manufacturer does not recommend changing the brand of oil. If you purchased one specific product to replace it, then it is better to use it in the future. Or use the services of the same auto repair shop.

If you carefully study the technical specifications in KIA, you can highlight the following important information:

  • Manufacturer's recommended engine oil is Shell HELIX;
  • filling volume 3.3-3.49 liters;
  • API Service classification – 4 or higher;
  • temperature range for recommended viscosity values ​​from -30С (5W20) to +50 (20W50)

At the same time, a reminder for the driver states that before pouring oil, you need to make sure that the surface near the filler cap, as well as the filler hole, is clean. The oil dipstick should also be clean.

These indicators are especially important if the car is operated in dusty, polluted conditions. For example, when driving on country dirt roads.

Timely cleaning of these parts (dipstick and cover) will protect the engine from dust and sand.

KIA Rio engines of later releases are made with no gaps between rubbing parts. Oil with a lower viscosity penetrates into gaps better, lubricating parts better.

Oil with a viscosity of 5W-40 almost does not flow into narrow gaps, leaving them without lubrication. Due to incorrectly filled oil, early engine wear occurs. That is why it is important to follow all manufacturer's recommendations when changing the oil.

This requirement applies to both gasoline and diesel engines.

It is more important to choose the right oil for the KIA engine not by brand name, but by API quality class, IlSAC. It is important to take into account that the manufacturer recommends a different oil for each generation of KIA.

The more modern the engine, the higher the quality the product should have. API SL and ILSAC GF-3, for example, are recommended only for first generation KIA.

Higher quality oils - API SM/SN and ILSAC GF-4/GF-5 - are quite suitable for cars produced in 2000-2005.

Rio 2005-2009 requires the use of API SM and ILSAC GF-4 oils. As in the previous case, the oil is of a higher quality, for example, API SN and ILSAC GF-5 are quite suitable options. Lower quality oil cannot be used.

In KIA Rio 2015 it is recommended to use API SN and ILSAC GF-5 quality oil. If we are talking about a KIA Rio with a diesel engine, according to the manufacturer’s recommendation, you should use oil of API CH-4 quality, but lower.

Recommended oil

It is important to use only high-quality and suitable oil to extend the life of the engine and ensure its smooth operation. Moreover, carefully selected lubricant reduces fuel consumption. Therefore, it is extremely important to pay attention to the factory specifications and tolerances before purchasing the appropriate oil.

So, in the case of Kia Rio 4, you need oil with the characteristics of API-SN and ILSAC GF-4, and ILSAC GF-5 is even better. Another important parameter is viscosity, which is selected depending on climatic conditions. For example, mainly in summer a viscosity of 20W-20 or 25W-50 is required. In winter, 0W-30, 0W-40 or 5W-30 is recommended, and for all-season use, 10W-40, 10W-30 or 5W-40 is suitable.

Based on the above parameters, the recommended engine oil for the Kia Rio 4 is the original Hyundai Turbo SYN Gasoline or Hyundai Premium LF Gasoline SAE 5W-20 synthetic fluid.

Kia Rio engine - how much oil

First generation DC, 2000-2005

Kia Rio DC in Russia and many developing countries had the status of an affordable entry-level family car, which was a worthy alternative to the post-Soviet models Samara and Lada 110. In addition, it was a relatively safe and comfortable car with a fairly spacious interior and high-quality assembly. The design of the car lacks proportionality, which is not a drawback due to the rather original and memorable streamlined shapes in the style of the 90s.

Fourth generation FB, since 2016

The Russian-made Kia Rio FB is an almost complete copy of a similar model called Kia K2. Among the stylistic changes, one can highlight the rear platform for the license plate, moved from the trunk lid to the bumper. In addition, the front of the car is distinguished by an original bumper and a new radiator grille, and a different multimedia system is installed in the cabin. Otherwise, the Rio FB is still a redesigned Solaris, but at the same time remains true to Kia’s corporate style. From the co-platform model, the car borrowed modernized aspirated engines with a volume of 1.4 and 1.6 liters (100-122 hp), operating with a manual transmission or automatic transmission.

Gasoline engines from 2017

  • 1.4 100 l. With. G4LC, oil volume - 3.6 liters, tolerance and viscosity: API-SN; SAE 5W-40, 5W-30, 10W-40, 10W-30, 0W-40, 0W-30

Factory requirements for engine oil for Kia Rio

Motorists often change lubricants themselves. Monitor the cleanliness of the drain hole and dipstick and prevent dust and dirt from entering the oil container.

They also ensure that the engine oil for the Kia Rio 3 meets the following requirements:

  • Fluidity. Running the rubbing elements of the unit “dry” leads to their premature wear. Due to its fluidity, the oil envelops them. However, the opposite property - viscosity - is important during long periods of inactivity: motor oil fills all cavities and does not flow down parts. This is especially important in frosty weather.
  • Ability to contact metal surfaces. When the engine is running, the oil heats up. It liquefies and loses its lubricating properties. Therefore, an important indicator of lubrication is the ability to form a thin film on rubbing parts. To obtain such characteristics, manufacturers use additives. In hot weather they add thickness to the liquid, in cold weather they make it more fluid.
  • Engine cleaning. During operation of the unit, combustion products are formed on its parts, which then enter the lubricant and settle in the filter. Thanks to this, engine elements remain clean and operate longer.
  • Corrosion protection. There is always some amount of water vapor in the motor. The lubricant prevents metal corrosion from developing.

Engine fluid cools the rubbing elements of the engine and fills the gaps between them.

What are the tolerances depending on the type of oil, engine and year of manufacture of the car?

Oil consumption

The condition of the power unit can be assessed based on many criteria, including oil consumption. Exceeding the permissible flow rate is the cause of a malfunction or poor quality of the lubricant. Of course, a sharp increase in oil consumption will alert any car owner who has to find out the reason for the excess consumption. It is important to keep in mind that failure to promptly monitor the condition of the oil (for example, its poor quality or low level) can lead to costly repairs.

What determines oil consumption?

  • on the characteristics and degree of wear of the engine (power, number of cylinders, age)
  • on climatic conditions and frequency of maintenance
  • on the condition of the filter (if it is clogged or damaged, then oil consumption will naturally increase)
  • on the characteristics of the oil itself

Normal oil consumption

During the break-in period during the first 5000 km, oil consumption should not exceed 1 l/1000 km. This consumption is considered acceptable even after replacing the piston rings. Below are the oil consumption rates in constant operation mode for runs of 5-150 thousand km (after running-in)

  • 0.25 l/1000 km – in favorable conditions
  • 0.4 l/1000 km – at high speeds and with increased loads
  • 0.5 l/1000 km – in mountain conditions

What is the consumption rate for a car with high mileage?

If the car's mileage exceeds 150 thousand km, then the consumption rate is considered to be 0.35-0.55 liters.

What is the oil consumption per 100 liters of fuel?

For new gasoline engines25 ml
For older gasoline engines100 ml

There are cases when oil consumption is 0.5 l/100 l of fuel. This indicator is still considered acceptable, but undesirable. In this case, there is a high risk of the engine jamming while driving, so it is better to immediately contact a service station to solve the problem with overrun.

Oil change intervals

The manufacturer states that the oil needs to be changed every 10 thousand km. But service specialists urge you to do this when the product has reached 80-90% of its standard life, i.e. after 8-9 thousand km.

This advice is optimal for those who drive a lot on the highway or on open roads in the city.

If we are talking about constant stops in traffic jams, you will need to fill a new portion after 7 thousand km.

Causes of premature wear

There are 3 key reasons for increased wear of the protective lubricant mixture:

  1. Driving on low quality gasoline. When such fuel burns, more soot is released. The consequence of this is contamination of the lubrication supply system.
  2. Poor engine condition. As cylinder compression decreases, the proportion of combustion products in the engine housing increases.
  3. Aggressive driving. First of all, operation in “start-stop” mode.

Fat burning: causes and solutions

  1. Plug leakage occurs when the engine is warm and under load. To check this version, you need to warm up the engine and see if there is an oil puddle under the car
  2. Poor quality oil not only leads to excess consumption, but can also be the cause of many other problems. In this regard, it is recommended to purchase oils with protection against counterfeiting. Such products include Ravenol, Mobil, Shell, etc.
  3. Oil separator malfunction. To check this version, you need to assess the degree of contamination of the oil separator outlet pipe. If it is in good working order, then it will have a small amount of plaque in the form of ash at its output.
  4. Coking of the piston rings of the cylinders occurs due to the aging of the oil, which only dirty the engine and does not bring any benefit. Such fluid primarily affects the cylinder oil scraper rings, which over time become clogged with dirt and malfunction. As a result, oil enters the combustion chamber of the fuel in large quantities. Prevention will help solve the problem: thorough washing and changing the oil three times. In the worst case, you will have to contact a service center for washing with a special agent (the procedure is called ring decarbonization)
  5. Piston rings are damaged. In this case, the problem of excessive oil consumption will be relevant even after washing the piston rings, which are seriously worn out and must only be replaced
  6. Poor fuel quality, wear of spark plugs or ignition coils, problems in the fuel system - all this causes rapid aging and excessive oil consumption.
