Many experienced car owners know that the quality of the oil and its certain indicators determine how stable and easy the engine will start in cold conditions.

If in the summer months the oil should only protect parts of the engine from high temperatures and loads, then in cold weather other characteristics must be taken into account.

It is worth saying that the division of petroleum products into lubricants for winter / summer is now irrelevant. Today, in auto oil stores, there are mainly all-season products.

In other words, today universal lubricants are sold that can be used all year round. Also, over time, the boundary between oily fluids for gasoline / diesel engines disappears.

There are more and more consumables that can be poured both in diesel engines and in internal combustion engines on gasoline. It has not been possible at the moment to create a truly universal lubricant that is effective in any engines.

This is due to the peculiarities of the functioning of power units and the fuel used. Any car enthusiast should know what winter engine oil must be used in winter conditions, how the markings on canisters are deciphered, how to control the amount of car oil and top it up in the engine in winter.

  • What kind of lubricant to pour into the engine in winter

    Petroleum products in stores, for the most part, are considered universal. However, many drivers before the start of winter are still in a hurry to change the oil fluid.

    It must be said that replacing the engine oil in winter is very useful, especially when the old oil has used up at least one-half of its life.

    How to choose consumables for winter, taking into account the viscosity index and other indicators that are quite significant for the proper functioning of the engine and comfortable driving?

    It is necessary to pour into the engine those lubricants recommended by the manufacturer of the machine. Recommendations can be found in the operating manual. The list is not limited to a couple of items.

    Not only power depends on the characteristics and quality of the used car oil. Lubrication affects elasticity, ICE noise, fuel costs, ease of starting in cold conditions, and so on.

  • It is well known that a thick oily liquid forms a strong lubricating film. This allows the engine to operate with less noise. The chance of leakage of oil seals, linings, and other sealing parts is reduced. In view of this, drivers, especially those who have traveled more than a hundred thousand kilometers, pour viscous car oil into the internal combustion engine in the summer, observing the tolerances and recommendations of the automaker). This is due to the fact that with mileage, the gaps between the contacting parts increase. In other words, if the engine first used oil, for example, 5w30, then after a run of a hundred thousand kilometers, it is advisable to switch to the "forty". It must be taken into account that thick oil products become even more viscous in winter and are poorly pumped. As a result, the engine, which was easy to start with grease in the summer season, is difficult to start in cold weather. In such a situation, it is necessary to immediately change the car oil.
  • You need to understand how to check the lubrication in the engine. Pull out the special dipstick before starting the engine without warming up. Check the state of the grease, how quickly it collects in a drop at the tip of the dipstick. If you notice that the oil product is too viscous, then it needs to be changed.

    Considering that the lubricant becomes thicker in winter, you need to understand how to properly add oil to the engine without over/underfilling. Oil must be poured exactly according to the level.

    If you check the amount of car oil with a cold engine, then the data may not be accurate, since the lubrication level decreases at low temperatures.

    In order to accurately determine the volume, a good warm-up of the engine is performed. Then the motor is turned off, they wait a quarter of an hour. During this period, the finally diluted car oil will leak into the sump. The readings on the dipstick will make it possible to objectively assess the level of lubrication.

    Obviously, the thinner the oil, the easier it is to start the power unit in winter. If you find that the frosting oil you are using is not suitable, choose another one.

    The choice of motor oil for the winter

    Key indicators of lubricant, which must be taken into account before purchase, can be recognized by special markings. For winter conditions, an oil with the appropriate viscosity and temperature parameters is required. The following products are the best choice:

  • 0w Very fluid. Even at very low temperatures (up to forty degrees) it retains fluidity, passes well through the oil complex;
  • 5w Recommended for use in regions with severe winters;
  • 10w Optimal for cars operated in “mild” winter conditions;
  • 10w All-weather lubricant, optimal for both warm winters and hot summers.
  • Temperature regime of engine oils

    It must be remembered that the lower the 1st number, the thinner the oil product will be after the power unit warms up and reaches high temperatures.

    A low-viscosity consumable lubricates contacting parts less effectively than a thick oil product. Liquid lubricant forms a thin film, therefore, motor wear increases.

    It turns out that for a stable start-up and the least wear, you need to pour liquid oils that are not able to protect the engine when heated. It is advisable to follow the recommendations prescribed in the operating manual, to maintain a balance.

    For example, the manufacturer wrote that it is possible to fill the engine with both “thirty” and “forty”. In this case, make a choice based on the ambient temperature.

    If in the winter season the temperature usually does not fall below seven degrees, then the "magpie" is considered the best choice. If the cold reaches minus twenty, choose 5w30.

    Remember that with the advent of summer, the car oil will have to be changed to a thicker one in order to better protect the internal combustion engine. In view of this, some experts advise pouring liquid oil into the power unit in winter and thick oil in summer, that is, replacing the consumable seasonally.

    Specialists and experienced drivers pay attention to the fact that the most important thing is the approvals of the engine manufacturer. When choosing a lubricant, first of all, you need to take into account temperature and viscosity indicators, then the car manufacturer’s tolerances.

    Only then is the type of motor oil determined (mineral, synthetic, semi-synthetic) and attention is focused on the brand of petroleum product, its characteristics and price.

    It turns out that it does not matter whether you use Liquid Moli, Castrol or Mobile. The main thing is that the oil filled in is not fake, suitable for a particular motor, has the necessary viscosity index, and is in accordance with the tolerances of the automaker.

    Conclusion

    Considering that today many types and brands of lubricants are freely sold, you should not stop your choice on the most inexpensive products.

    It is advisable to buy consumables in trusted stores. This reduces the chance of acquiring a fake. If you know for sure that a very low temperature will soon set in, do not choose mineral water. It is better to use a semi-synthetic petroleum product.

    If the car is usually parked in a warm room, and sits on a cold street for no more than three hours, then you don’t need to use liquid lubricant in winter.

    It will only be necessary to carry out the insulation of the space under the hood, the power unit. This will make it possible to reduce the cooling rate of the engine.

    Another way to reduce the likelihood of increased wear, to facilitate starting without warming up, is to install a preheater, use automatic engine warm-up, and so on.

    Most of today's car alarms are equipped with a function that makes it possible to automatically warm up the engine in cold conditions.

    If this option is not available, it is possible to install a special autorun module. The power unit can be started from a distance, that is, it can be warmed up in advance.

    Autostart can be configured so that the car starts, for example, once every 2 hours. This allows you to prevent severe cooling of the machine’s engine when idle, and reduce the likelihood of problems with starting without pre-warming.
