We took three fully synthetic imported motor oils with SAE 5W-30 viscosity from the leading manufacturers that occupy the lion's share of the domestic market - ExxonMobil, Shell and Castrol. To this trinity was added the not so common, but no less famous Motul oil.

How was it tested? On each of the oils, a specially prepared bench engine was rotated in the specified modes for one hundred and twenty hours, while its characteristics were compared at various stages of testing. The engine is a domestic VAZ-21114 eight-valve with injection, with a modified control program and a piston oil cooling system.

Why is it not a foreign engine? Test conditions do not allow. The technique requires before and after testing to open the motor, measure, defect, photograph and weigh the parts. And modern non-nashen engines cannot be disassembled and assembled - the crankshaft cannot be removed there. More precisely, you can remove it, but putting it back is already prohibited.

After a fixed time, we took - three times - samples of the oil to assess the rate of its aging. Changes in the physical and chemical parameters of the oil were monitored, as well as the content of wear products in it. And opening the engine clarified the idea of ​​deposits and wear.

To weed out doubts about possible fakes, we sent fresh samples of oils to the laboratory to determine the basic physical and chemical indicators and compared them with the indicated manufacturers. If they match, then the oils are real, not fake. I was surprised by something else: the initial parameters of all four oils are almost the same. Are they from the same barrel? From different! This became clear after measuring the dynamic viscosity over the entire temperature range. But first, let's remember what viscosities are in general.

KINEMATIC, DYNAMIC AND HTHS

There is a direct relationship between oil viscosity, friction loss and wear rate of the friction unit. In classical hydrodynamics, two viscosity characteristics are distinguished - dynamic and kinematic. It is the dynamic viscosity of the oil that is important for the motor, since it takes into account the change in density with temperature. And kinematic viscosity is important for oilers; it can be accurately measured with a capillary viscometer. Previously, the viscosity parameters prescribed by the SAE class limited only the possible range of changes in the kinematic viscosity of the oil at a temperature of 100 ° C. This range for SAE 30 oils is 9.3-12.6 cSt; for SAE 40 oils it is wider than 12.6-16.3 cSt.

The SAE classification has now been extended with dynamic viscosity restrictions at 150 ° C. This is the so-called high-temperature viscosity HTHS (High-Temperature, High-Shear).

Previously, it was believed that SAE classification was sufficient for the selection of oil, and then it turned out that it was not enough. Oils from one group at operating temperatures can differ in viscosity by tens of percent, and this is essential for the operation of the motor. Therefore, an additional restriction was introduced.

Manufacturers of modern oils are guided by opposite priorities. For example, Shell claims the low viscosity of Helix Ultra oil, which results in low friction losses. And Motul has specially developed 8100 X ‑ clear FE, which has a high HTHS value. Who is right?

For the sake of completeness, let's go through all temperatures - from winter to quite operating modes, like in a fully warmed-up engine. The highest values ​​of the high-temperature viscosity HTHS at the first test - in the oil Motul 8100 X ‑ clear FE, as promised by the manufacturer: 3.2 mPa · s versus 2.7 mPa · s for Mobil. Takeoff run - almost 20%! This means that this oil will reduce the load on the bearing by 20% - or will increase the pressure on the bearing by the same 20% without deteriorating its operating conditions. The price for this is the highest dynamic viscosities at low temperatures: 8330 mPa s for Motul oil versus 6220 mPa s for Mobil oil. This means that it will be more difficult to start a motor with Motul oil in the arctic and antarctic.

However, it is more interesting to trace the dynamics of changes in this parameter during the entire period of testing. Oils Mobil 1 ESP Formula and Motul 8100 X-clean FE for 120 hours of torture with a Russian engine and Russian (not the best, as everyone says) fuel changed their parameters slightly and quite predictably. During the tests, the dynamic viscosity in the entire temperature range increased by only 3-5%.

But Castrol Edge FST and Shell Helix Ultra oils have changed their viscosity by 21-28%! Moreover, the increase in the viscosity of Castrol oil began almost immediately - such a dynamics is not typical for the usual behavior of the oil. And Shell oil did a good job until the middle of the tests, but gave up in the second half of the cycle. As a result, by the end of the tests, the advantage that these oils had over Motul oil in terms of viscosity at low temperatures completely melted. Those planning to use these oils in the harsh northern conditions have something to think about.

An even more expressive picture, reflecting the rate of aging of oils, is given by the analysis of the dynamics of changes in the kinematic viscosity at 100 ° C.

And again: the viscosity of Motul oil is practically unchanged. For Mobil oil, the change in viscosity is more noticeable, and by the end of the test period it reached the threshold value. Castrol, on the other hand, showed a very significant increase in viscosity at 100 ° C, well beyond the acceptable range. The most interesting thing is that the viscosity at 40 ° C began to decrease by the end of the tests - this can be seen from the data in the final table. The viscosity index flew as much as 210!

Viscosity index is an important parameter of engine oil, which characterizes the rate of change in viscosity with increasing temperature. The higher it is, the smaller the difference between the viscosities at high and low temperatures. For full synthetics, it usually lies in the 160-180 range.

And one more oddity of Castrol oil. Typically, the base number gradually decreases: a complex of detergent additives is triggered. And here on the contrary - growth!

Perhaps, from deposits formed in the engine, calcium or another element returns to the oil, to which the device reacts. By the way, for the other three oils, the same method gave the expected result.

We evaluated the energy saving of oils twice, comparing in the modes of our cycle both with fresh oil and with 120 operating hours. These results are also tabulated.

Here again it is appropriate to return to the conversation about HTHS. The oil with the highest HTHS value, Motul 8100 X ‑ clean FE, also performed better here. However, all tested oils, judging by the results, may well be classified as energy-saving. But those with a lower viscosity growth rate changed the fuel consumption and engine power the least after a cycle of long tests. The effect of high-temperature viscosity was most clearly manifested in the analysis of the protective functions of the oil. Analysis of the content of wear products in oil samples taken at the final stage of testing clearly reveals the unconditional leadership of oil with high HTHS. This is the Motul 8100 X-clean FE. It is quite understandable: the higher the viscosity, the greater the thickness of the separating layer and less.

Autopsy of the engine after test cycles showed approximately the same final level of high and low temperature deposits, with more stable oils giving slightly better results. But in general, all oils in these parameters showed a high result, characteristic of high-quality synthetics.

NOT FOR RUSSIA?

Why did the oils perform differently during the tests? Two of them - Motul 8100 X ‑ clear FE and Mobil 1 ESP Formula - worked without remarks, while the other two showed less optimistic results. The very nature of oil aging, when the viscosity begins to walk, and other parameters as a whole remain normal, most often indicates that the additives included in the used additive package conflict with something.

In starting this expertise, we wanted to continue the theme of the “oil plague” that we raised three years ago - the unpredictable decomposition of oil, in which black tar is formed in the channels of the lubrication system, the oil pan, and the valve mechanism. This disease has killed more than one hundred motors. And the oilmen named Russian gasoline as one of the possible culprits of this trouble. Then we found other causes of the "plague", moreover, confirmed by experiment. But it was also necessary to check the version about the influence of bad gasoline.

The solution was found after our examination of cheap 95 gasolines (ZR, 2015, No. 5), during which it turned out that most of them contain prohibited methanol. This is the kind of gasoline we used for our tests.

Thus, our research has confirmed that bad gasoline can really spoil the oil, and with it the engine. Yes, but Motul 8100 X-Сlean FE and Mobil 1 ESP Formula oils, working on the same gasoline, did not make any complaints about it! This means that the additive package can be adjusted in such a way that the oil works normally under our conditions. Another thing is that not everyone succeeds.

In the meantime, we repeat: go around unverified gas stations in a wide circle! When it comes to choosing an engine oil, we advise you to go for products with a higher HTHS value.

The motor, nerves and wallet will be more whole!

How was

Our results are of a relative nature, applicable only to the comparison of the four tested synthetics. When comparing the motor characteristics of the engine, another oil was included in the test - a relatively simple anonymous semisynthetics of the same viscosity grade, taken as a basis for comparison. Bench testing completely eliminates the uncertainty inevitable when testing on a real motor under normal operating conditions. In the latter case, much depends on the operating modes of the engine, its technical condition, driving style, fuel quality, weather overboard and a number of random factors.

The applied methodology makes it possible to assess the comparative quality of engine oil according to features that are usually taken into account when they are admitted to use by various car manufacturers. Let's list these signs.

Energy saving is determined by the change in the average specific fuel consumption when operating on the test oil in comparison with the base oil.

Wear protection is determined by the change in the mass of the control parts (), the change in the size of the parts, the content of wear products in the engine oil sample taken after the tests.

Tendency to form high temperature deposits is determined by visual assessment of the level of contamination of the side surfaces of the pistons. The tendency to form low-temperature deposits is determined by the change in the mass of the control weight elements - engine parts installed in the valve cover (oil separator mesh) and in the oil pan (oil filter receptacle).

Environmental performance are determined by the change in the toxicity of exhaust gases during engine operation according to a standard test cycle on a test oil compared to a base oil.

In addition, the comparative pace and its effect on engine performance were assessed. The resource indicators of the oil were characterized by the dynamics of changes in its viscosity, base and acid numbers, and a change in dispersing ability.

The viscosity limits determined by its SAE class were used as the rejection parameters, on the basis of which the oil serviceability preservation was assessed. For SAE 5W ‑ 30 oil, the kinematic viscosity, measured at 100 ° C, should be in the range 9.3–12.6 cSt. In addition, the oil was rejected if at some stage of testing its base number dropped by more than 50% of the initial value.

High temperature oil viscosity

In modern engines, the oil temperature in the working area can reach 180–200 ° C, especially in the piston ring - engine cylinder friction pair. The viscosity of oils of even the same SAE group at these temperatures can vary significantly. Thus, our previous examinations showed that for oils of the group “forty” at 150 ° C the kinematic viscosity can vary in the range of 5.4–6.8 cSt, that is, the takeoff run reaches 25%! For the thirty, the relative difference may be even greater.

That is why the concept of high temperature viscosity HTHS has appeared in the revisions of the SAE J300 rules since 2001. This is the dynamic viscosity of the oil, determined on a rotational viscometer under fixed conditions - at a shear rate of 106 1 / s.

Manufacturers of modern oils have the same goal - to optimize engine performance, but to achieve it they choose mutually exclusive methods. For example, in the description of Shell Helix Ultra oil, it is said that due to its low viscosity, it reduces friction losses. And Motul has specially developed 8100 X-clean FE with a high HTHS value.

Who is right? Let's turn to the theory. Any friction pair in an engine is a kind of bearing: cylindrical, if it is a crankshaft bearing, or flat (slider), if, say, a friction pair between a piston ring and a cylinder. So, one of the most important indicators of the quality of the bearing is the load factor. It is defined as the ratio of the average bearing load to the operating viscosity of the oil multiplied by the shear rate, and this is multiplied by the square of the ratio of the operating clearance to the bearing diameter. The value of the load factor must lie within certain limits. Exceeding it leads to a sharp increase in the wear rate and friction losses, but too low a loading factor leads to an increase in friction losses.

The load and speed in the bearing are the operating parameters, we do not touch them. If we decrease HTHS, we automatically increase the bearing load. And we can compensate for this only by the size of the working gap - it must be reduced. But even here there is a limit! This means that each motor, with its design features and operating modes, has its own optimal high-temperature viscosity HTHS.

Moreover, even in the case of one motor, each of its modes of operation will have its own optimal HTHS. And the law is simple - the higher the load, the higher the viscosity should be.

What do the rules say? They only stipulate the dependence on the viscosity class. For "twenties" - not less than 2.6 mPa · s, for "thirties" and part of "forty" - not less than 2.9 mPa · s, for the rest - not less than 3.7 mPa · s. Note - no less! Therefore, in the light of modern trends in the creation of motors, the position of the Motul brand is still closer to us. The test results confirm this opinion.
