What the 5W30 numbers mean. Fluids: Engine oil, everything you need to know. How to choose engine oil

 The main purpose of the lubricant engine is to protect engine elements from dry friction and ensure normal operation of the power unit while maintaining tight cylinders. l A suitable choice the oil engine works regularly for a long time. 5W30 oil is the most popular among synthetic lubricant species of famous brands.

The largest local manufacturers of Rosneft lubricants, Lukoil ensure the high quality of oil products produced. Synthetic motor oil5d30 produced here enters the acceptable price category this grease is fully adapted to the work of many types of total strength in local climatic conditions.

5W30 car oils manufactured in Russia are successfully used at high environmental temperatures, acceptable for use in warm latitudes.

which means the symbolism put on the 5w30 engine oil label

When purchasing lubricants, buyers wonder about decryption 5W30 is that the information in the inscription, any kind of preferred product. Decryption of engine oil is necessary for the implementation of the right choice of lubricant products.

SAE 5W30 is decrypted as follows:

Of the number of numbers, 30 are necessary, and the result is minus 25. The temperature is equal to 25 years the start of the cold engine.

Letter W corresponds to the first letter of the winter word and means that the brand can be applied in northern latitudes.

According to, the speed of the oil is determined by the high temperatures in the running engine.

The value of the number after W is characterized by oil balz during the hot engine

Due to the fact that the local climatic conditions for the operation of the car vary sharply, select the necessary lubricants after a comprehensive study of the patterns on the product. The poster on the poster corresponds to a special classification of oils for sae viscosity.

This classification helps choose the desired grease brand for its car through its technical characteristics depending on the temperature at which the 5W30 engine oil will be used.

Benefits Use SAE 5W 30 Lubrication

5W30 synthetic oil has indisputable advantages. Excellent properties of these materials contribute stable engine work during operation in harmful urban environments that have a negative impact on engine elements:

Long work in inactivity;

Find a car in road congestion conditions (traffic jams);

Run the device at short distances;

Increase the content of dust in the atmosphere.

The right choice of oil producer does not contribute to increasing the duration of engines. Due to its unique design and special additions, which have a  5w30 engine oil label , this lubrication has properties that provide the following functions:

Protecting energy unit elements from premature destruction;

Reducing the harmful effects of corrosion;

Remove carpenter layers from working surfaces;

Cooling parts and action engine knots.

Engine oil 5W30 resists the temperature inside the working power unit equal to 150°C, without changing its valuable qualities. Choosing oil for a particular car engine, you need to be based on the recommendations made in determining the collection by automakers.

Despite the brand's popularity, it is necessary to choose lubricants with parameters corresponding to the requirements put forward by the manufacturer of this car.

Features of chemical composition of oil products

The additives included in sae 30 engine oils are designed for precisely defined functions. Thanks to a balanced range of inserts supplement oil liquids become suitable for use in specific engines. Each type of lubrication contains additives in accordance with standard car oil standards.

Any type of car oil application depends on the choice of the owner of the car. Based on the age of cars, engine characteristics, high-speed modesThe owner prefers a certain type of oil:

Mineral oils.

Synthetic or semi-synthetic.

The use of mineral lubricants in machines produced more than five years ago leads to a decrease in oil consumption and increases engine use, he said.

If modern imported under the hood is installed total strength recommended using synthetic varieties of lubrication. In this series, there is artificial oil SAE 5W3 belonging to well-known international brands capable of withstanding climate differences and the density of traffic loads in the city.

Oil liquids test

Before receiving a quality certificate, test passing and chemical analysis are performed. On stickers, the box provides information on compliance with lubricant requirements. Test data is given to inform consumers.

Test oils occur in laboratory conditions on special stands. A test is conducted for the viscosity of the lubricant product depending on the temperature inside the work engine.

This type of diagnosis lets you determine the ability to start a cool engine in frost and the degree of the engine toaster from high temperature in hot weather. The test shows the thickness and changes of the protective film from the driving surfaces of the work parts as a result of the increase in the internal temperature of the engine.

The test lets you introduce consumers to the features of lubricants manufactured by various manufacturers for  5w30 engine oil label.
