Any vehicle owner wants his car's engine to last for a very long time. To do this, you need to make sure that all rubbing parts are covered with high-quality lubricant. Choosing a car oil today is very simple - there is a wide selection of products on sale.
Instructions
Step 1
You don't even have to visit a service station. You can choose a car oil yourself and pour it into the car, the result will be obvious.
Step 2
Remember that the choice should be approached very carefully, because due to an error, a number of catastrophic events can occur. These include: the appearance of intense carbon deposits, rapid destruction of rubber parts, jamming. Coking of diesel engines can also be observed (we are talking about their nozzles and piston rings), intensive wear often occurs.
Step 3
If you are the owner of a foreign car, the question of choosing the right oil becomes even more relevant. Today the car park is very diverse, there are old and completely new vehicles. Owners of old cars do not have instructions on hand that would tell you which oil to use. In addition, there is a wide selection of oils on sale, they have different prices. How do you choose which oil is best for you?
Step 4
Always pay attention to the characteristics of the car oil. The industry began to produce mineral and petroleum oils after it became possible to separate fuel oil into fractions.
Step 5
Modern engines are very demanding on the quality of the car oil, because the engine experiences high thermal and mechanical loads. In order to improve the quality of the oil, additives are added to it. For example, the use of antiwear additives can reduce the wear of rubbing parts.
Step 6
There is a wide range of gear and engine oils on the market today. Be sure to study their technical characteristics before choosing a car oil, only then you should make a purchase. The quality of the oil and its viscosity are the most important characteristics. Speaking of viscosity, it is worth considering the climate in which the vehicle is operated. Consider the operating season as well.
Step 7
Be sure to study the product labeling, only after that is it worth making a purchase. The viscosity of the oil is determined according to foreign standards, it is indicated as it is accepted in the SAE - the society of automotive engineers (USA). If these letters are written on the label, then you should know that the numbers after them characterize the viscosity. If the car oil is intended for winter, the letter W is put in the designations (winter - winter).
Step 8
Let's take a closer look at SAE J300. This standard includes OW, 5W, 10W, 15W, 20W, 25W. These are winter viscosity grades, the use of such oil guarantees a cold start of the engine if the air temperature is -30 ° C to + 5 ° C. Summer varieties have no letters in the designation, there are only viscosity grades 20, 30, 40, 50 and 60.
Step 9
When traveling by car throughout the year, it makes no sense to buy seasonal oils, it is better to choose a car oil designed for all seasons. Watch the label carefully. Multigrade oil is designated as follows. The letters SAE are indicated first, followed by the winter and summer indicators.
