Which oil is better to be poured into the engine - synthetic, semi-synthetic or mineral?

For today among automobile owners there is a lot of disputes about what oil it is better to fill in the engine. Some prefer mineral fluids, others recommend taking synthetic oils, while others do not choose anything other than semisynthetic. In addition, the problem of choice is created by many companies that advertise their products as the most modern and optimal. In this article, we'll look at a few criteria for choosing lubricants and find out which oil is best poured into the engine.

Viscosity

The first thing you should pay attention to is the viscosity of the lubricant. Often, the characteristics of motor oils are divided into two types - summer (that is, those that should be filled in the summer) and winter (well, everything is clear now). So, every manufacturer, whether it is an "Opel" or a domestic GAZ, initially indicates in the operating manual the exact viscosity of the oil, which must be poured in this or that time of the year. There are no precise indicators here, because each company sets its optimal range of data, and the difference between them is very high.

Car mileage

The answer to the question of which oil is best poured into the engine, directly depends on the life of the machine, that is, its total mileage. Many masters recommend to motorists to use synthetic little only for new cars. Well, for the old there is nothing better than mineral fluids. Also worth noting is the exception - if you are the owner of a sports car, which is 5 years or more, it is better to give preference to "synthetics", since the engine in such machines works at very high revs.

What was the liquid earlier?

Examination of engine oils showed that in many respects the choice of the right fluid (in particular, on cars that were in use) depends on the lubricant on which their engine worked before. For example, if during the last 50-80 thousand kilometers the motor worked on a "mineral water", then this time it is best to pour in it "synthetic". Why? The thing is that the first kind of oils in its properties forms in the aggregates various cracks and deposits, which can only be washed by a second kind of lubricant (it has stronger acid values, so it is very useful for the engine). But it is possible that "synthetics" will wash useful deposits, so the second time it should not be flooded. But then which oil is better to be poured into the engine after the synthetic fluid? In this case, it is best not to immediately go back to the "mineral water", but use a compromise - semisynthetic lubricant. Due to its special properties, it does not damage the engine's performance and at the same time prepares it for the next consumption of "mineral water".

As you can see, there is no unambiguous answer to the question of which oil is better to be poured into the engine. Each car is special, and it is necessary to fill it with only that liquid that will not depress the motor (we just listed these cases). Therefore, take care of your iron friend and pour into it only quality liquids!
