Today among car owners there is a lot of debate about how best to pour oil into the engine.Some people prefer the mineral fluid, others recommend taking synthetic oils, and others nothing but a semi-synthetics do not choose.Besides the problem of choice create many companies touting their products as the most modern and optimal.In this article, we look at several criteria for selecting lubricants and find out how best to pour oil into the engine.
Viscosity
The first thing you should notice is the viscosity of the lubricant.Often the characteristics of motor oils are divided into two types - summer (ie, those that must be filled in the summer) and winter (well, here is all clear).And so, every manufacturer, whether it is "Opel" or domestic gas, originally indicated in the manual operation of an accurate oil viscosity that is needed to fill in a particular time of the year.Exact figures are not here, because every company exhibits its optimal range of data, and the difference between them is very high.
car Mileage
answer to the question of how best to pour oil into the engine depends on the age of the machine, that is, its total mileage.Many masters recommend to motorists to use synthetic small only for new machines.Well, in the old there is nothing better than mineral fluid.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 "synthetic", as the engine in such machines operate at very high speeds.
What fluid was before?
Examination of motor oils has shown that in many respects the choice of the desired liquid (in particular, in cars that were used) depends on what the lubricant of the engine was running before.For example, if during the last 50-80 thousand kilometers the engine worked on the "mineral water", but this time it is best to fill with "synthetics."Why is that?The thing is that the first kind of oil in its properties forms aggregates in various cracks and deposits, which can wash only the second type of lubricant (it has a strong acid performance, so the engine is very useful).But it is possible that the "synthetic" wash and utility deposits, so the second time to fill it should not be.But then what kind of oil is better to pour into the engine after the synthetic fluid?In this case, it is best to not go directly back to the "mineral water" and 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 intake, "mineral water".
As you can see, a clear answer to the question of how best to pour oil into the engine, no.Each car - especially to fill and it is necessary only that the liquid that will not inhibit the operation of the motor (these cases we just listed).So take care of your iron friend and pour in a liquid only quality!
