Oil choice for winter use on identification mark
The most important parameters of oil which you should consider when buying greasing liquid, can be learned on identification mark. We had a separate publication about labeling of automobile oils. Today we will consider, what identification mark should be chosen for drivers in cold climatic zones or during a winter season.
It is important to find an optimum combination of viscosity, the minimum and maximum temperature of use of liquid in this situation. The majority of motorists in the coldest zones where temperature reaches-45 degrees Celsius in the winter, use the following oils:
0W30 - the least viscous oil which practically doesn't react to low temperatures;
5W30 - oil with sufficient viscosity and quite good parameters of temperature endurance;
10W30 - liquid for less cold climatic zones which one use in winter time in northern parts of Europe;
10W40 - actually multigrade oil which can be used during summer season.
One of the most noticeable shortcomings of oil with the first figure on identification mark 0 is too liquid state in an operating mode. When the engine is warmed, such lubricating fluid doesn't provide due lubricant of the DVS elements and results in its increased wear.
In some climatic areas you can use only such kind of oil; after all it guarantees a starting engine operation actually at any temperatures. For the summer period all oils stated above, except 10W40, should be replaced with more viscous options.
