Synthetic And Mineral Oils
Synthetic oils, unlike the mineral have a maximum thermal and chemical stability. Chemical stability means that the work of synthetic oils in the engine with them does not occur any chemical transformations (oxidation, parafinizatsii, etc.), which could affect its performance. Thermal stability means maintaining the optimal value of the viscosity of the oil in a wide range of temperatures that means easy and safe engine start in the cold, while the maximum protection for the engine in its highest-temperature zones at high speeds and loads. Owing to the peculiarities of its molecular structure of synthetic oils have a higher (compared to mineral), fluidity and penetrating power.

Problems associated with the transition to a 'synthetic', usually arise in cases where the previously used low-quality oil change intervals recommended violated or there has been a hit in the oil foreign substances, such as, for example, coolant, additives in the oil, etc. In this case the engine may appear significant deposits. Usually at the same time there is partial or complete loss elasticity (up to cracking) seals (gaskets, valve stem seals, etc.). Unlike mineral oils, which 'wash' deposits in the engine slowly, layer by layer, synthetic oils (Due to their inherent high strength and penetrative ability) causes detachment of deposits from the inner surfaces of the engine, which can lead to clogging of the mesh maslopriemnika, oil channels are working in oil starvation and, consequently, failure of the engine.
