Protecting Your Car in Sub Freezing Weather

The brake fluid is probably the most important lubricant in your car. However, the other fluids are just as important too, since they must be in good Xe đông lạnh condition to make sure that your car is totally winterized. In this article, we will be discussing the other fluids that make your car work, including what you can do to make sure that will continue to work well even when subjected to the extreme cold of winter.

Wiper Washer Fluid
In summer, the wiper washer fluid is usually composed of nothing but water. It is automatically sprayed in front of the windshield to remove stuff that impedes the driver’s vision. During winter, where temperatures can go as low as a -25 degrees, pure water will freeze.

Thus, it is important to put anti-freeze into the wiper washer fluid container.. If some level of fluid resistance can still be observed, try adding more anti-freeze gradually. This is to make sure that the whole mixture will have a lower freezing point.

Replacing the wipers with brand new ones is also recommended. Unlike rain, snow may come with various particulate matter like sand, that may give your wipers a hard time. Thus, it is advisable to replace the wipers as soon as the first snowflake falls.

Engine Oil and Gear/Transmission Oil
First off, one question: What should be used, synthetic or Traditional oil?
Most car experts will tell you to switch to synthetics for greater efficiency.
Traditional oils are derived from crude oil, which are made up of literally hundreds, if not thousands of substances. Even if unwanted components are almost wiped out through various chemical processes, there are bound to be some impurities that can damage your car, such as asphalt, sulfur, and nitrogen compounds. Synthetic compounds, on the other hand, are entirely created from scratch, which means that their chemical composition is much more pure traditional oils. In short, synthetics have much less of those that a car doesn’t like to have.

The most common synthetic oils for winter are 0W-30, 5W-30, and 10W-30, where W denotes that the particular oil is made for cold climates. The part to look out for in these names is the number before W. In general, lower numbers mean a lower viscosity (i.e. it is more freely flowing) when subjected to drastically lower temperatures.

Hence, of all three common types, 0W will be the best for extreme cold. Take note that a car warms up as soon as the engine runs, so that viscosity in winter counts when the car is being started. Furthermore, viscosity grades of oil do not refer to their actual viscosity. Rather, they refer to how much the viscosity changes given a certain change in initial operating temperature.
