How to choose the right engine oil for a car depending on the season?

In summer, the oil heats up, it works better at high temperatures, helps the engine not to overheat. The consistency of summer oils is usually more viscous and tolerates high temperatures better, ensuring optimal engine lubrication, reducing friction and wear, improving efficiency and protecting against overheating.

In winter, the oil becomes thicker and circulates worse through the engine. Therefore, in cold weather, it is better to use synthetic low-viscosity oils so that it is easier for the starter to start the engine, and the oil quickly reaches all the parts.

It is recommended to use all-season engine oils for most modern passenger cars. Their labeling, for example, 5W-30 or 10W-40, indicates their suitability for use in both summer and winter.

All-season oils have optimal properties for cold start in winter and reliable engine protection at high summer temperatures.

For regions with extremely low winter temperatures or very hot summers, the use of oils with a wider temperature range may be justified. For example, in conditions of severe frosts, it is advisable to choose an oil with an index of 0W or 5W, and in hot climates – with a higher second numeric index (for example, XXW-40 XXW-50).

Always follow the recommendations of your car’s manufacturer as listed in the owner’s manual.
