Oil "Lukoil" (synthetics) 5w40: reviews. Oil "Lukoil" (synthetics) "5w40 Suite"

The key to long-term and accident-free operation of any car is often a high-quality engine oil. Especially this statement is true, if we talk about domestic climatic conditions, when a single cold start of the engine can "fly away" a significant part of its resource.

What to do and what to use?

Unfortunately, motorists do not always buy really high-quality lubricants, because they are guided first of all by their cost. The realization that such a path is flawed and does not lead to anything good, comes only after the first serious engine failure and major repairs. For the sake of fairness, we note that many high-quality oils do not always differ in sane price, and therefore motorists have to look for a cheaper alternative worthy.

Does it exist in nature? Fortunately, yes. For example, oil "Lukoil" (synthetics) 5w40. The testimonies indicate that with characteristics that are not inferior to many imported analogues, it is much cheaper. In addition, this lubricant is much better adapted to very unfavorable climatic conditions, which is far from in all cases possible from foreign peers.

So, many French oils already at a temperature below -30 degrees Celsius turn into jellies. How does the oil "Lukoil" (synthetic) behave 5w40? Reviews say that everything is in order. In order not to be unfounded, we will give the main operational characteristics of the products.

Declared characteristics

The manufacturer himself gives the following data, on which one can judge the suitability of using oil in the specific conditions of our country:

• Viscous grade - 5W-40.

• At a temperature of 100 ° C, the kinetic viscosity is not less than 12.5 / 14.5 mm2 / s.

• The minimum viscous index is 150 units.

• The minimum flash point (with access to oxygen) is -210 ° C.

• It freezes at -37 ° C.

• The average alkaline number is 7.5 mg KOH / g (not a very good indicator).

• The percentage of sulfate ash content is 1.2% of the mass volume.

That is the difference between Lukoil (synthetic) and 5w40. The characteristics of this oil are such that it is possible with a clear conscience to put it on a par with many well-known imported lubricants. They are not too different in all the above features from domestic products, often cost several times more expensive.

Many motorists (even from northern regions) confidently say that with Lukoil the car will start better (if to compare with domestic and foreign analogues). In addition, during overhaul and preventive maintenance, it is found that there is almost no trace of deposits and deposits on the parts.

Important note

If you poured this oil for the first time, and we are talking about a car that has been operated for a long time using not very high-quality oil and fuel, experienced motorists are strongly advised to rinse the engine before replacing the lubricant.

After you travel about seven to eight thousand kilometers, the oil will need to be drained again, and in this case you will need to use some certified engine cleaning compound, from which the additives of Lukoil probably washed away a huge amount of dirt. Experienced in this matter, people say that after such a procedure the car starts to go much better, fuel and oil consumption is reduced.

Of course, you should not expect that such a banal operation will increase the power of the engine or bring its technical state to the indicators of what was just bought. Miracles, unfortunately, do not happen.

Does the oil have international certificates of conformity?

Yes, this also characterizes the oil "Lukoil" (synthetics) 5w40. Reviews say that it can easily be poured into the engines of almost all foreign cars, that for domestic products - a rare achievement. Foreign experts fully agree with this assessment, since they have awarded a lot of international certificates of conformity to the lubricant. The most important of them are the following: SAE, API SJ / CF, ACEA-A3-98 and ACEA-B3-98. Even the company Mercedes Benz in the recent past has tested and approved this lubricant for use in their cars. And it says a lot! Thus, the oil "Lukoil" (synthetics) 5w40 SN is quite suitable even for pouring really expensive and status cars into the engines.

Supplied in canisters of one, four and five liters, as with all normal producers). The average price is 100, 400 and 450-500 rubles, respectively. Already for only one cost in the domestic oil can literally fall in love, as foreign producers for their products ask at least twice as much money.

Main Features

What else is characterized by the oil "Lukoil" (synthetics) 5w40? We will review the comments about it a little later, but for the time being we will describe what, in Lukoil's opinion, is its production, which is so beloved by domestic motorists.

The product under consideration is universal, suitable for use at any time of the year. Produce it from a high-quality mineral base with a low content of paraffin and sulfur, adding for the improvement of characteristics practically the same packages of additives that foreign companies use.

In principle, it is because of this that this lubricant with full right can be considered an analogue of the average statistical samples. Experienced users believe that in the latter case we overpay exclusively for the brand, while the real characteristics remain the same.

Motorists recommend!

In addition, Lukoil Lux 5w40 (synthetics) fully meets the requirements of all eminent automakers, can be used with equal success in the most modern gasoline engines that are equipped with a turbocharger, and in diesel engines of cars, trucks, and buses. It is difficult to say whether this lubricant is poured into passenger buses in "field" conditions, but the owners of small diesel trucks are satisfied with it.

They say that "Lukoil" allows saving about 5% of fuel, if you compare oil with the products of other companies. Given its extremely low cost, the picture is more than attractive.

Useful properties of lubricant

Being absolutely similar in this parameter with the best samples of foreign lubricants, "Lukoil" 5w40 (synthetics) perfectly cleans gasoline and diesel engines from carbon deposits and other pollution categories, while perfectly protecting their parts from corrosion in all temperature ranges.

On the elements of their designs, several times less deposits appear, which helps almost immediately to start the engine in winter conditions, and its rapid pumping and heating help to start instant lubrication of all parts immediately after the engine starts.

Important! Unlike other domestic lubricants, "Lukoil" 5w40 (synthetics) does not have any harmful effect on catalytic afterburners of modern cars, and also perfectly protects from wear and tear of even high-powered turbo-charged diesel engines.

Sulfur and other troubles

Particularly important is the latter circumstance due to the fact that all of the above applies to diesel engines operating on low-quality diesel with a high sulfur content, as well as to all categories of injector gasoline engines.

Drivers of diesel cars in Russia say that only thanks to this oil it is possible to avoid serious consequences, having been forced to refuel for a long time on dubious gas stations. However, from the need to replace extremely expensive injectors, this does not relieve, unfortunately.

Tests of independent experts

So we came to the most interesting part. No matter how good (according to the manufacturer) there would be oil "Lukoil" (synthetic) 5w40, it is always interesting to learn about the results of independent experts' tests. As a rule, their data is much better characterized by any product. So, here are the actual results of the studies, according to which the "field" TTX greases are as follows:

• At 100 ° C, the actual viscosity (kinetic) is 12.38 mm2 / s.

• The maximum flash point, provided free oxygen is available, is in the area of -224 ° C.

• Solidifies the oil "Lukoil" (synthetics) 5w40 at a temperature of only -40 ° C and even lower.

• The average alkaline number is 9.68 mg KOH / g (which is much better than official data, oddly enough).

• At a temperature of 20 ° C, the density is 0.8621 kg / l.

• The average ash content is 1.18 wt%.

• At an ambient temperature of -30 ° C, the dynamic viscosity was in the range of 6,600-4,900 mPa.

This is how the oil "Lukoil" (synthetics) 5w40 manifested itself in the research. Tests, by the way, showed very good results, which many from the Russian lubricant and did not think to get.

What does all of this mean?

Interesting figures, but what can they say to an average motorist? Let's open and decipher the values of individual indicators. We note that there are practically no remarks, but we should especially emphasize the low viscosity values in conditions of rather low ambient temperatures. Why is it so important? The fact is that this figure affects the crankability of engine parts in the winter with a cold start.

And what do the owners themselves say? With this, everything is fine: it turns out that using this oil a cold start no longer causes difficulties even at temperatures down to -33 degrees Celsius. Almost everyone says that with this lubrication the engine under such conditions works much more smoothly and more confidently, which can not but rejoice.

A spoon of tar

Alas, the test on a photometer showed that there is a very large amount of suspended impurities in the oil. This indirectly indicates that in the lubricant - a large proportion of oxide products. It's a shame, because the indicators of the alkali number in this test are quite decent. However, there is nothing criminal in this: we can simply conclude that the main indicators are in the average range, not much inferior to the bulk of common oils.

How are things with the environment?

Very popular among a considerable part of car owners is the oil "Lukoil" (synthetics) 5w40 "Lux". Reviews say that at a ridiculous price we get an excellent oil, which in its characteristics is quite comparable with many foreign analogs.

The only point concerns environmental cleanliness. Lubrication, which initially marked an increased content of products of oxide and other suspended impurities, can cause a low purity of exhaust products. Therefore, on such a machine it is not necessary to go to those countries in which zealously monitor the cleanliness of the air.

However, in practice everything is not so sad. In the reviews there are no mention that the use of this lubricant would prevent normal pass technical inspection of the car, related, among other things, with the analysis of the quality of the exhaust. So the buyers of this lubricant are quite satisfied, since for real operational properties this indicator does not affect the exact account in any way.

The main conclusion

So, how did the "Lukoil" (synthetics) oil show up with 5w40 Lux? Feedback, as well as the results of laboratory studies, which we already mentioned above, indicate its decent quality. And it is gratifying, as domestic lubricants can rarely please really impressive characteristics.

This oil can be safely recommended to almost all motorists. Fortunately, the lubricant is suitable for both diesel and gasoline engines. One of its drawbacks is perhaps the high photometric contamination index, which implies a large mass fraction of suspended particles from oxidation products.

But in all other respects motor oil "Lukoil" (synthetic) 5w40 is little inferior to its imported "colleagues". Motorists report that, with its regular application, the engine's run is significantly increased before its overhaul, and on the internal parts of the power plant there is practically no deposit and deposits. Agree that for a synthetic lubricant with such a price indicator is close to fantastic!

That is why "Lukoil Lux" 5w40 (synthetic) is an excellent oil that is available to almost anyone who wants at the expense of its low cost. In this case, the buyer will not get any dubious lode, but a high-quality product, which will certainly be in the liking not only of him, but of his car, regardless of the characteristics.
