Car owners often wonder about what kind of oil is best to choose: semi-synthetic or synthetic?If you choose should take into account certain technical characteristics: age, technical condition, make and mileage.In thinking about what needs to be: semi-synthetics or synthetics, it should be a little bit aware of their differences.
Synthetic motor oil for cars is the product of artificial origin, which is derived from natural gas or oil in the deep processing.It does not change its properties even after prolonged use and little influenced by external factors.
semi-synthetic oil is obtained as a result of the merger of several bases in a certain proportion.
Mineral oil is a product of natural origin which is obtained after distillation of crude oil, and then the next purification.
differences between synthetic and semi-synthetic oils
What is the relative stability of synthetic motor oil, and what does it matter for the ordinary motorist?Composition of the synthetic oil includes molecules which performance scrutinized.This leads to high chemical and thermal stability.Therefore, synthetics are not so terrible cold temperatures and overheating, as the other oils.This ensures safe operation of the engine in the winter and in the summer thanks to the preservation of the optimum viscosity index at high engine loads and high speeds.If this choice does not matter which part of the oil from: synthetic or semi-synthetics.
Chemical resistance allows for a long time does not change the properties, even in the absence of interaction between the oil and the motor.Semisynthetics characterized by high stability, unlike mineral oil, which is considerably inferior.But in certain conditions should make a choice in favor of synthetics, leaving behind the debate about which is better, semi-synthetics or synthetics.If the car has considerable mileage, then refuel the engine is semi-synthetics, as it gives a high level of carbon monoxide.If the vehicle is not operated at low temperatures, and in this case we can safely use the semi-synthetics.But it is worth noting that the semi-synthetic oil should be changed more frequently than synthetic.
synthetic oil for cars is helpful in severe weather conditions and high temperatures.Besides its life longer.But do not pay attention to this feature, since synthetic oil is not suitable for all cars.Therefore, not everyone will think about what oil is better than synthetic or semi-synthetics.For example, in most older machines used a semi-synthetic, which is popularly referred to as mixed.The main difference between oils such as synthetic or semi-synthetics, a molecular composition of their foundations.Synthetics inherent high thermal and chemical resistance.
