The choice of oil viscosity, taking into account the climate, is, first of all, following the recommendations of the manufacturer of your car, indicated in the instruction manual. Automakers are already taking into account the temperature conditions for different regions.
However, if you live in a region with very cold winters, you should prefer oils with a lower first digit (for example, 0W or 5W) to ensure easy engine start and quick lubrication at low temperatures.
If your region is characterized by very hot summers and you often operate your car under high loads (for example, in traffic jams, when driving with a trailer, off-road), it may be worth paying attention to oils with a higher second viscosity (for example, 5W-40 or 10W-40 instead of 5W-30). if it is allowed by the manufacturer. However, it is important to remember that modern low-viscosity oils (for example, 0W-20, 5W-30) have excellent high-temperature characteristics due to advanced additives, and a thicker oil is not always the best choice.
In the era of modern technology, when one all-season oil is able to work effectively over a wide temperature range, there is no need for seasonal oil change.
The main thing is to follow the recommendations of your car’s manufacturer, choosing an oil with the correct viscosity and appropriate tolerances. This ensures maximum engine protection, durability and optimal performance in all climatic conditions.
