Tip 1: How to distinguish a synthetic oil
Synthetic oils are organiccompounds widely used as a lubricant for various types of engines and mechanisms. Sometimes synthetic oils can be used as a coolant.

Synthetic oils are characterized by: a flat viscous-temperature curve, low volatility, resistance to low temperatures and simultaneously - fire resistance, high lubricity, chemical, thermal stability and radiation resistance. In particular, the chemical stability is manifested in the fact that, when interacting with other substances during engine operation, synthetic oils are not subjected to oxidation, paraffinization and other processes that impair its performance. The thermal stability of synthetic oils is their ability to maintain optimum viscosity over a wide range of temperatures, which allows the engine to be started, for example, in the cold, and then operate under high temperatures in the high-speed mode and under heavy loads.

As practice shows, the peak sales of syntheticmotor oils fall on the fall. It was at this time, thanks to them, it was possible to achieve the necessary low-temperature characteristics with less effort. In addition, compared to mineral oils, synthetic fibers have a higher viscosity index, better fluidity, greater resistance to aging, lower volatility, better antifriction properties and increased resistance to shear deformation.

You can also distinguish synthetic oils fromNo problems with cold start of the engine, more economical fuel and lubrication consumption, reliable protection against high-temperature deposits. Synthetic oils quickly come to the engine parts after a cold start, thus ensuring their less wear and tear.
Tip 2: How to distinguish synthetic oil from mineral oil
Currently, the market of automotive accessorieshuge, car owners can choose for their car any product depending on their needs and capabilities. But how to navigate among such an assortment? For example, when choosing an engine oil, the question may arise which one is better for the car? There is a synthetic and mineral motor butter, and also semisynthetic. Depending on the goals and the situation, you need to choose a more suitable one. So what's the difference between oils?
You will need
- - Mineral motor oil;
- - synthetic motor oil;
- - Consultation of the dealer center.

First, we should orient ourcar. Typically, manufacturers of certain brands often conduct testing of their vehicles. Based on this, they often give advice on the type of oil, which is the most suitable for this type of engine. Dealers in the service centers can consult you, selecting exactly the right products for the brand of your model

It is necessary to take into account seasonality and certain properties of motor oils. So, the mineral butter is natural, that is, has a basis in itsoriginal form after oil refining. A synthetic is created by the synthesis of a natural base with so-called additives - additives, each of which has certain properties. The creation of a synthetic base was necessary when a mineral butter, used for aviation purposes, becamefreeze at low temperatures. Under the influence of chemical molecules, the natural base has acquired new properties - resistance to temperature changes. So it was invented a synthetic mineral butter. In the ability to maintain their originalproperties (viscosity, fluidity) with changes in the external environment and is one of the main differences between synthetic oil and mineral oil. Thanks to this property, those who use synthetic butter, the engine starts easier. Because at first it heats up, then overheats, then cools down - and the synthetic butter at this time it functions as usual.
