9 best engine oils for KIA RIO

The need to use engine oil in all cars is the same - to ensure constant lubrication of moving parts, timely remove heat and prevent friction wear processes. However, different engines have different specifics of work, which affects the need for the use of oils of strictly defined classes and tolerances. In this article, the editors of expert.bigbadmole.com/en/en/, together with staff experts, tried to figure out which of the oils put on sale are the best for the Kia Rio - a Korean small car.

Factory requirements for engine oil for Kia Rio

The first and most important requirement for the maintenance of the engine - the timely replacement of oil after a certain mileage. For Kia Rio, the recommended interval is 10 thousand kilometers, but professionals recommend a shift after reaching 80-90% of the resource output (that is, every 8-9 thousand kilometers).

Among other things, it should be understood that when choosing oil it is necessary to focus not only on the name, but also on the quality class. At the current stage of production of Kia Rio, manufacturers require the use of at least API SN and ILSAC GF-5 in an oil lubrication system - these are optimal tolerances guaranteeing long and stable engine operation throughout the entire life cycle.

The rest of the characteristics specified in the car manual are as follows:

1. recommended brand of engine oil - SHELL Helix;
2. filling volume - from 3.30 to 3.49 liters;
3. optimum operating temperatures for recommended viscosity grades - from -30 to +50 ° С (the values ​​given are typical for oils from 5W20 to 20W50);
4. level, according to the classification of API Service (American system of classification of motor oils) - from 4 and above.

The best synthetic oils for Kia Rio

SHELL Helix Ultra Professional AM-L 5W-30

Rating: 4.9

As prescribed recommendations, the leader among synthetic oil becomes another product manufactured by SHELL. Helix Ultra Professional AM-L 5W-30 is a compound developed by applying a special technology for the distillation of natural gas, free from impurity elements and negative properties of petroleum products. An addition to the basic base is a whole package of active additives, an important role among which is assigned to detergent components. The emphasis on them is the main feature of the oil, whose task lies in the immaculate preservation of the cleanliness of the internal part of the engine.

According to the technical specifications, the SHELL Helix Ultra Professional AM-L 5W-30 works well in low temperature conditions (it freezes at -45 ° C), due to which it provides easy start of the engine even in severe frosts. It has an optimal viscosity index (69.02 mm²/ s at 40 ° C) and thus increases the efficiency of the engine, though not by much (power increase is not higher than 1.7-2.1%).Fully compliant with API standards SN / SF, and thus ideal for use in Kia Rio.

TOTAL Quartz 9000 Future EcoB 5W-20

Rating: 4.8

The second candidate for leadership in the ranking is low viscosity synthetics with a predominance of mechanisms to reduce the harmfulness of exhaust gases and the function of cleaning the engine. Due to the finest and most complete purification of the composition from sulfur and phosphorus, the oil has an optimizing effect on the catalyst, thereby reducing the rate of its production and the release of harmful compounds into the atmosphere.

Among other things, the structure of TOTAL Quartz 9000 Future EcoB 5W-20 reduces fuel consumption by an average of 3.35% (test score ACEA M111FE), which gives a good economic effect when used over a long period of time. According to users, despite the reduced viscosity, the oil provides easier start-up of the engine during the cold period, but signs of solidification begin to appear already at -30 ° C. In this respect, the effectiveness of its use is questionable, but not all regions of Russia are exposed to such severe frosts. In the aggregate of positive features, it is a good alternative to the line of oils from SHELL, with comparable indicators of working resource and market value.

Castrol Magnatec Professional E 5W-20

Rating: 4.7

We awarded the third line of the rating to the oil of the Castrol Magnatec line created using CM Intelligent Molecules technology, which affects the synthetic composition at the molecular level. In the end, Professional E 5W-20 has a complex effect on the motor, expressed not only in lubricating, cleaning and cooling properties, but also in creating a dense modified film on the surface of metal parts that is resistant to thermochemical effects. This film provides engine protection at the most vulnerable moment of its operation - during start-up, when the lubricant rests in the oil pan.

Despite the reduced viscosity, Castrol Magnatec Professional E 5W-20 perfectly manifests itself when working in cold conditions, freezing completely only at a temperature of -45 ° C. An excellent indicator to facilitate the launch of the engine in the cold. According to the users, this train perfectly maintains 10 thousandth runs, giving, with moderate vehicle operation, the opportunity to travel another 1-2 thousand kilometers without losing useful properties. This is an excellent oil, which successfully rolls around cars of American and Korean production (including the Kia Rio).

LIQUI MOLY Synthoil High Tech 5W-30

Rating: 4.6

The fourth line of the rating goes to the traditionally high-quality product of the company Liqui Moly. Under other circumstances, it could claim a place higher, but in comparison with competitors, its manifestation is somewhat ... standard. All performance characteristics were balanced, and manufacturers did not intend to place any obvious emphasis on anything. However, it is still possible to mention a couple of moments: for example, a very large supply of working resource (about 12-13 thousand kilometers). Thanks to the advanced additive package, the oil is aging very slowly, practically does not succumb to oxidation and is not wasted on waste, which is quite a painful topic for new Kia Rio engines.

Good viscosity parameters in Synthoil High Tech 5W-30 are interspersed with resistance to temperature changes, and in cold weather and in hot weather, starting the engine is pretty easy. Synthetic feels great in the cold, freezing only at -45 ° C. In general, there is nothing more to say here: consumers are very satisfied with the operation process, in particular, with a large working resource. And what about the price parameters ... we conclude this way: in terms of quality, it is quite adequate.

Motul Specific 948B 5W20

Rating: 4.5

The development of this synthetics was carried out taking into account the features of Ford's engines, upon the request of which, in fact, the entire development process was initiated. However, the end result turned out to be very versatile: the Motul Specific 948B 5W20 was successfully used in Jaguar engines, in the Land Rover line, and in a number of low-end small cars, which is also our main model Kia Rio.

Unlike competitors by rating, this synthetics is allowed to mix with other types of oils, including mineral ones (however, we still do not recommend this). The composition has a high degree of purification from impurities (sulphate ash does not exceed 0.78% of the total mass of the oil), almost neutral base number (pH 8), as well as good resistance to work in the cold. In the condition heated up to 150 ° С, the HTHS-viscosity of the oil, according to tests ASTM D4741, is 2.6 MPa. The state is very bordering, and in the event of a change in temperature in the direction of an increase, the probability of breaking the integrity of the oil film is high. However, in its normal state, the Motul Specific 948B 5W20 works perfectly and is a popular choice among owners of Kia Rio and cars of a similar class.

MOBIL 1 ESP 5W-30

Rating: 4.5

Universal synthetic oil suitable for use in diesel and gasoline engines. It implements and includes many functions to ensure acceptable working conditions, which negatively (and these are the words of users) affects the size of the resource.

However, if you want to walk, and 8 thousand kilometers for you is an acceptable figure, then MOBIL 1 ESP 5W-30 is the best fit. Clearance under difficult working conditions (with catalysts, turbocharging and particulate filters) has a positive effect on power performance (1.9% increase in power), and also contributes to low fuel economy (2.43%) due to the reduction of friction losses at the nodes. Like Motul Specific, this oil can boast a high degree of purification: the proportion of sulphated ash in its mass does not exceed 0.8%, which protects the engine from residual sludge. Another strong point of the MOBIL 1 ESP 5W-30 is the pour point. The loss of turnover is observed at -48 ° C, and this figure is very good in Siberia. The product has earned a number of enthusiastic reviews from small car owners, with a few complaints about the high price.

The best semi-synthetic oils for Kia Rio

SHELL Helix HX7 5W-30

Rating: 4.9

According to all the canons of recommendations from manufacturers, the semi-synthetics of SHELL Helix HX7 5W-30 falls into the first stage of the rating of oils for Kia Rio, whose working potential is estimated to be 6 thousand kilometers. It is perfect for working in used engines of old models, as it contains a mineral base, and will not become redundant in brand new cars, whose engines have not yet been touched by a destructive wear mechanism.

The temperature range of the theoretical operation of this “universal” product is limited to -48 and 244 ° C, which is the full freezing point and flash point in an open crucible, respectively. In addition to approval from the Korean automaker, SHELL Helix HX7 5W-30 is recommended for use in Volkswagen and Mercedes-Benz cars, and also meets the requirements of four specifications (which include API SN of interest to us). This is a very good oil that will suit all lovers of reliability, economy and does not overdo it with an aggressive style of driving.

LIQUI MOLY Molygen New Generation 5W-20

Rating: 4.8

In one step from leadership (due to the lack of a manufacturer's recommendation), the LIQUI MOLY Molygen New Generation 5W-20 semi-synthetics stopped, which was based on the HC synthesis technology. In addition, the special development of Mlygen, which is aimed at improving the methods of cleaning the engine from solid sedimentary compounds, corrosion and other pollutants, has been added to the additive series.

Despite the fact that the pH of the oil is at a neutral level (pH 7.2), the additive complex contains components that neutralize the action of acids. The lubricating functions of Molygen New Generation 5W-20 contribute to a significant reduction in the friction coefficient between the parts, increasing fuel economy and increasing power (unfortunately, there are no specific data from studies on these items). The final point is the presence of 15 tolerances and approvals from automakers: American (Chrysler, General Motors, Ford), Japanese (Toyota, Honda, Suzuki, Subaru) and Korean (Hyundai, Kia).

Motul 6100 SAVE-lite 5W20

Rating: 4.7

It so happened that Motul 6100 SAVE-lite 5W20 was the third representative of semi-synthetic oils, suitable for use in the engines of the car Kia Rio. The development of this composition was sanctioned by a number of American manufacturers, which, in fact, gave approval for its use as part of their cars (this is Chrysler, General Motors and Ford).

The prefix "SAVE" in the name of the oil speaks of sharpening for the preservation of the working life of the engine by timely cleaning from solid deposits and neutralizing corrosive media, corrosion processes. The low pour point of Motul 6100 SAVE-lite 5W20 does not allow the composition to be used in severe frosts, but to some extent facilitated start of the engine still provides (up to about -20 ° C). Of course, it cannot be compared with opponents either by an indirect measure of the number of approvals and tolerances, or by technical characteristics. However, the owners of Rio love this oil. A popular assessment (opinion) often means much more than the notorious indicators of comparison.
