The basis for the selection of motor oils for the winter are their SAE Grade, you need to get acquainted with them, перед тем как выбирать automobile oils – prices available на них вы найдете в магазине Магнит Авто.
viscosity grades
- 0W-xx has an appropriate viscosity that ensures normal operation of the engine to -40?WITH;
- 5W-xx has an appropriate viscosity that ensures normal operation of the engine to -35?WITH;
- 10W-xx has an appropriate viscosity that ensures normal operation of the engine to -30?WITH;
- 15W-xx has an appropriate viscosity that ensures normal operation of the engine to -25?WITH.
one can understand that the oil should be applied to our climate from the above information such as 5w-40 or 5W-30 Extra, that allow in our climate to produce a comfortable cold start.
Even popular oil, such as mineral Helix HX5 15W-40 does not create problems, since the temperature below -25 очень редко встречаются на большей части территории России.
Considering the dilution of oil by fuel, passing into the sump, eg, when driving in traffic, we can be sure, that engine start is possible even at lower temperatures, what is guaranteed by the SAE.
Widespread in our climate zone oil class SAE x-40 well is protecting the motor, but contributes to increased fuel consumption. В свою очередь класс вязкости SAE x-30 является более дружественным в отношении к окружающей среде, as it provides a higher fuel economy.
Myth are the stories about the impact of low viscosity, e.g. 0W-xx fuel economy. Вязкость 0W-xx облегчает запуск двигателя при температуре масляного картера -40?with, but after several revolutions and engine warmup value ceases to be.
What else is worth remembering
Sometimes low winter SAE viscosity grades may be the cause of an accident, так как отличная текучесть и низкая вязкость при очень низких температурах может быть смертельной, for engine parts, blurred unevenly. With increasing temperature, the viscosity decreases very rapidly, and oil can not provide appropriate engine lubricant. High fluidity causes rapid draining oil from the lubricated parts, заставляя работать на “dry”.
Using winter diesel engines must always be mindful of listening to weather forecasts, as the current standard diesel vehicle allows the use at temperatures up to -20?C при которой происходит блокировка топливного фильтра. Ниже этой температуры кристаллизованный парафин блокирует насос, filter and fuel hoses.
In the case of sudden changes in temperature ads, must be added to the tank so-called additives, which will not allow to freeze diesel fuel filter and pump.
