Viscosity - the defining characteristic of the oil. It varies with temperature, and the tolerances of changes determine the temperature range of use of the oil. To start the engine at low temperatures, the best motor oils are those that do not have a high viscosity. This property is necessary so that the elements of the lubrication system can qualitatively deliver the oil to the friction surfaces and the starter power is enough to roll the crankshaft of a cold engine.
The engine oil rating of 2017 included the well-known manufacturers from the TOP-10:
- PC Supreme Synthetic 5W-30/;
- Liqui Moly Molygen NG 5W-30;
- ZIC A +;
- GToil GT Energy SN 5W-30;
- NGN Nord 5W-30;
- Super Car 2000 X1;
- Pennzoil Ultra 5W-30 Api SN;
- Ravenol TSI;
- Lukoil Lux synthetic 5W-40 API SN / CF;
- Сastrol Magnatec.
The best motor oils effectively remove wear products and excess heat from friction assemblies, making motor operation reliable and durable.
The best motor oil of 2017 was recognized as a product under the brand Castrol Magnatec, its use, both in diesel and gasoline power units, reduces fuel consumption and has a positive effect on the environmental performance of the vehicle's exhaust gases.

What engine oil is better: synthetic or semi-synthetics?
Car owners often face the question of which oil is better to pour, synthetics or semi-synthetics. For the optimal choice of lubrication, it is necessary to consider the parameters of the vehicle:
- It Ultra
- Ravenol
- ZIC A +
- Super 2000 car
These products showed approximately equal anti-oxidative properties. Sastrol Magnatec's performance is somewhat worse, but not significant.
Semi-synthetic engine oil rating 10W40, по усредненным показателям экспертиз, выглядит так:
- ZIC A + Gasoline VHVl.
- Super Car 2000 X1.
- It Ultra.
- Ravenol TSI.
- Castrol Magnatec.
The best semi-synthetic engine oil 10W40, according to the rating of engine oils semi-synthetics, experts recognized the product ZIC A + Gazoline VHVI. In addition, in Russia, this oil is inexpensive. It has excellent detergent, protective, energy-saving properties. Resource characteristics are optimal in a similar product line.
In order to make rational use of funds for car maintenance, during the warranty period of operation, it is necessary to follow the recommendations of the manufacturer. This practice exists all over the world. For example, the use of synthetic oil after mineral, in addition to an unreasonable increase in costs, can unpredictably affect the parameters characterizing the operation of a diesel or gasoline engine:
- Increased fuel consumption.
- Lowering the compression number - normal working pressure in the cylinders.
- The deterioration of the performance of the sealing cuffs, sleeves, gaskets.
- The appearance of previously unobserved noise.
- Increasing the content of harmful substances in the exhaust gases.
This effect of synthetic oil is caused by its base, which is a substance with high fluidity. Increased detergent properties, along with excellent penetrating power, act as a solvent. Getting on the deposits of carbon and slag, this grease partially cleans the parts from the products of operation, at the same time, changing the geometric parameters of the gaps in the parts and sealing materials. This directly affects the key operating settings of the engine, and not in the best way.
