Today, among car owners, there is a lot of controversy about which oil is better to fill in the engine. Some prefer mineral fluids, others recommend taking synthetic oils, and still others do not choose anything other than semi-synthetics. 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 will look at several criteria for choosing lubricants and find out which oil is best to fill in the engine.

Viscosity

The first thing to look at 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 in the summer) and winter (well, everything is clear here). So, everythe manufacturer, whether it be Opel or domestic GAZ, initially indicates in the operating manual the exact viscosity of the oil that needs to be filled in at one time or another of the year. There are no exact indicators here, since each company sets its own optimal data range, and the difference between them is very large.

Car mileage

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

What was the liquid before?

Examination of motor oils showed that in many respects the choice of the desired fluid (in particular, on used cars) depends on what lubricant their engine was previously running on. For example, if over the past 50-80 thousand kilometers the engine has been running on "mineral water", then this time it is best to fill it with "synthetics". Why? The thing is that the first type of oil, by its properties, forms various cracks and deposits in the units, which can only be washed out by the second type of lubricant (it has stronger acid indicators, so this is very useful for the engine). But it is possible that“Synthetics” will also wash out useful deposits, so it should not be poured a second time. But then what kind of oil is better to fill in the engine after a synthetic fluid? In this case, it is best not to immediately switch back to mineral water, but to use a compromise - a semi-synthetic lubricant. Due to its special properties, it will not harm the engine and at the same time prepare it for the next consumption of "mineral water".

As you can see, there is no definite answer to the question of which oil is better to fill in the engine. Each car is special, and you only need to fill it with the liquid that will not inhibit the operation of the engine (we just listed these cases). Therefore, take care of your iron friend and pour only high-quality liquids into it!
