Engine oil is of great importance, its quality is immediately reflected on the performance of the car and the shared resources of the machine.The oil is designed to lubricate the friction rotating parts, and cooling them in the process.It is filled through the oil filler neck, located on top of the engine valve cover.
For oils, there are certain requirements.First of all, the engine oil must be stable under various conditions.When the cooling and heating of its structure should not be changed.Finally, the engine oil for the car must have a constant viscosity.
What oils provide the above conditions and comply with all these requirements?
First of all, they are divided into the following categories: mineral, synthetic and semi-synthetic.
Mineral oils produced by refining crude oil.This engine oil low stabil- under certain conditions.This means that when the motor in different modes probability that mineral oil not retain their chemical properties is quite high.Simply put, this type of product does not provide adequate lubricating effect of the friction surfaces.Unfortunately, as the temperature of the motor oil viscosity increases and its properties deteriorate lubricants.
Another thing - synthetic engine oil.In performance is significantly superior to the mineral.All because synthetics create artificially.That is, the performance stability of this type of product is much higher due to the fact that most of its structure is present synthetic base.Synthetic oil is widely used in the engines of modern cars due to the stable viscosity and excellent cleaning and lubricating properties.
semi-synthetic oil - a mixture of mineral and synthetic species.Its main advantage is a lower price than the "synthetic".The indicator of stability when the engine is lower.A good option use "semi-synthetics" is a motor having a significant run, as this will burn synthetics.
Which oil to choose?
In fact, the choice of motor oil is not an easy task.Options on the market a lot of automotive products.This raises some doubts - synthetic or mineral?The answer is obvious, if you understand the basic operating characteristics of the engine particularly taken.For example, if the engine has high mileage, it friction parts are worn out.It follows that fill "synthetic" engine does not make sense, as this mineral oil is thinner and quickly burn out.This is an expensive engine oil, and it will often topped up, which is economically disadvantageous.In this case, mineral or semi-synthetic oil will be the most profitable option.
Incidentally, mineral oil should be changed more often than synthetic."Synthetic" less susceptible to temperature changes, longer maintains operational performance has better viscosity.This allows the use of synthetic oil in the engine working in different environments, at varying loads and various high-speed modes.
In fact, it is not recommended to save too, choosing oil for the engine.But it is important not to hurt, trying to ease the life of the motor.You must always remember that the quality of the engine oil depends on engine life.This means that by buying higher quality oil, the owner to protect itself from future problems encountered when necessary to repair the engine.The choice is yours.
