Car owners often wonder which oil is best to choose: semi-synthetic or synthetic? When choosing, it is necessary to take into account certain technical characteristics: age, technical condition, brand and mileage. Thinking about what is needed: synthetics or semi-synthetics, you should at least be aware of their differences.

Synthetic motor oil for cars is a product of artificial origin, which is obtained from natural gas or from the deep processing of oil. It does not change its properties even with prolonged use and is slightly affected by external factors.

Semi-synthetic oil is obtained by combining several bases in a certain proportion.

Mineral oil is a product of natural origin, which is obtained after the distillation of petroleum and subsequent purification.

Differences between synthetic and semi-synthetic oil

What does stability mean relative to synthetic motor oil, and what does it matter to the average motorist?Synthetic oil is formulated with molecules that have been carefully engineered for performance.

This results in high chemical and thermal resistance. Therefore, synthetics are not as afraid of low temperatures and overheating as other oils. This ensures safe operation of the engine both in winter and in summer due to the preservation of the optimal viscosity index at high engine load and high speeds. With this choice, it does not matter what composition the oil has: synthetics or semi-synthetics.

Chemical stability allows for a long time to not change properties even in the absence of interaction between the oil and the engine. Semi-synthetics are characterized by high stability, unlike mineral oil, which is significantly inferior in this. But under certain conditions, it is worth making a choice in favor of synthetics, leaving behind disputes about which is better: synthetics or semi-synthetics. If the car has a significant mileage, then it is worth refueling the engine with semi-synthetics, as it gives a high degree of carbon monoxide. If

the car is not operated at low temperatures, then in this case, you can safely use semi-synthetics. But it is worth noting that semi-synthetic oil has to be changed more often than synthetic.

Synthetic auto oil proves useful in severe weather and high temperatures. In addition, its service life is longer. But don't pay attention tothis characteristic, since synthetic oil is not suitable for all cars. Therefore, not everyone will think about which oil is better than synthetics or semi-synthetics. For example, most older cars use semi-synthetic, which is also popularly called mixed. The main difference between oils such as synthetics or semi-synthetics is the molecular composition of their bases. Synthetics have high thermal and chemical resistance.
