How to choose engine oil

Motor oil performs important functions during the operation of the Iron Horse with its owner. Prevents wear out and protects against corrosion, absorbs fuel combustion products, serves to cool the engine. Not any oil can approach your motor. High quality, but unsuitable will be much more harm than average quality oil, but the corresponding parameters of your engine.

First of all, when choosing an oil, it is recommended to pay attention to its viscosity and SAE standards. From this parameter, the ease of cold start of a car motor in a cold time depends on this parameter. Depending on this characteristic, the oil is all-season, winter and summer. The viscosity is selected, based on the design and characteristics of the motor, in which modes it works. For winter, SAE 0W, 5W, 10W, 20W oils are suitable for summer - SAE 20, 30, 40, 50, 60. Universal substance for all seasons - SAE 5W40, SAE 10W-40. Almost all firms producing oils use these standards. Therefore, first find out what kind of oil you need, and then define the oil brand for your car.

Abbreviation of the type 0W-40 means the following:

the first digit is the temperature, when the oil is reached, the oil cannot pump the pump, does not pass through the filter, that is, its viscosity is lost;
W - from English "Winter", winter time;
the number after the dash is the maximum temperature at which it is allowed to ride by car, since with an increased temperature mode, the lubricating properties of engine oil are lost, and the parts of the engine begin to wear faster.

In addition, when choosing an engine oil, it is recommended to consider the quality class:

Classification of API quality oil: oil for gasoline engines (SG, SL, SN) and for diesel (CF-4, CI-4). The first letter is decrypted: "S" - (Service), "C" - (Commercial). The second letter on the label: larger oil, than it is further from the beginning of the alphabet. In brackets also indicates the year of approval of the specification - for example, CJ-4 (2010).
Classification of ACEA oils: oils for gasoline engines of vans, minibuses, passenger cars - class A (A1-96, A5-2002); Oils for diesel engines, minibuses, cars - class B (B1-96, B5-2002), oil for cargo transport - class E, universal oils of the new generation - class C, suitable for diesel engine and gasoline engines. The higher the first digit, the characteristics are better. The second number is the year of approval of the specification.

It is quite difficult to determine which brand to buy oil. After all, a lot of advertising and all sorts of tips. We will not consider them all, but listen to the recommendations of professionals. They advise using Mobil 1, Valvoline, Castrol mineral oils. It is important to distinguish the original from the fakes. Before buying, carefully examine the holograms and protective stickers, and if there are doubts, ask the seller to show documents confirming the cooperation of the store and manufacturer.

Another important point: you need to decide, synthetic oil to use in the engine or mineral. To make the right choice, it is recommended to deepen in particular its production. Mineral oil is manufactured by refining and distillation of oil, it is naphthenic and paraffin. The best viscosity characteristics are paraffin base oils. Synthetic oil is produced, synthesizing certain chemical compounds, it has a smaller viscosity, and the composition includes active additives that contribute to the dissolution of the Nagar inside the engine.

It is known that synthetics has advantages over mineral oil:

contributes to low fuel spending;
the ability to work when the temperature is low;
lack of reaction to overheating;
chemical stability remains.

Such advantages affect the price of the product. However, it is better to ride on old oil than to top up, but cheap. Therefore, manufacturers and invented a compromise solution - mixing synthetics and mineral water, as a result, it turns out a semi-synthetic oil for use in any types of engines.

When you decide to change the oil, you need to buy an oil filter (well-established Mann, Fram) and the engine washing fluid, for example, Liqui Molyclean Liqui. This tool is used immediately after purchased the machine, and if you change the type of oil. Before merge the old oil, remove the dipstick and analyze the smell. Upon the presence of the smell of Gary, rinse must be necessary. Remember that it is impossible to pour the synthetic after you used mineral oils. There are at least two reasons. In the first case, the synthetic oil will begin to destroy the old Nagar, which, so to speak, would fit, and the engine will work with overloads. The second reason is that the synthetic oil has a low viscosity and starts to flow through the dangling cuffs, and this will deliver additional troubles.

These are the basic tips for choosing an engine oil. The main thing is to follow you so that you will not be fake. Buy oil not on the market, but in specialized stores!

According to what is better from domestic producers: LUKOIL or ROSNEFT. It is said that if you take LUKOIL, then the big risk is praised to the fake, and Rosneft the risk of fake is zero.

I believe that our oil is better because the price is cheaper, and the quality of the oil is like imported. I advise everyone to buy our manufacturers and I go to Rosneft.

I do not agree that at a cheap price there may be normal quality. I moved at one time from Lukoil on the moth moth, the difference is tangible. The engine works quieter, there is nothing to pour between the planned replacements of the oil.

Yes, there can be no high-quality oil to cost cheaply, from which it is done if it is worth a thousand rubles. Ha natural you will make the difference, I myself went on the onion, then it was tired of throwing money into the pipe, went on the moth lyrics. This is the sky and the earth is simply, I forgot about all the problems that were before it with a car.

Synthetic is also different. Almost everyone writes 100% synthetics, but in fact a mixture. We need to watch tests. Impaired by oil evaporation, viscosity, outflow temperature and a bunch of everything. Lately Last time LM Molygen NG 5W30. Very good engine oil with mileage for 100. You can also pour with new water. And the flushing of course did during the transition to this oil, then lm, as they advise

For His Mahina, and it has 110000 km, it has chosen an oil to the semi-synthetic moth. I am satisfied with the quality of oil, I go a year without problems, the car behaves like a new one. Everything is good in this oil. In addition to the price.
