What Type of Oil Should Be Used in Winter?
2 Answers
What type of oil to use in winter depends on the different temperature conditions. The specific details are as follows: 1. 0W oil: Used when temperatures do not drop below minus 35 degrees Celsius. 2. 5W oil: Used when temperatures do not drop below minus 30 degrees Celsius. 3. The functions of oil: Lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption, and wear resistance. 4. Method for changing oil: Lift the car, remove the protective plate, and place a container under the oil drain screw; loosen the oil drain screw, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain screw after draining, and wipe with a tissue to check for leaks; reinstall the protective plate and lower the car, then add oil at the filler port.
I remember last winter, my car had a particularly hard time starting on a -10°C morning, with the engine making strange noises. Later, I found out the issue was with the engine oil—regular oil becomes too thick in low temperatures, reducing its flowability and affecting cold starts. It's best to choose a low-viscosity grade for winter, such as synthetic oils starting with 0W or 5W. For example, 5W-30 is ideal for typical winter conditions, as it remains fluid down to -25°C. If you live in extremely cold regions like Northeast China, 0W-20 performs even better. This type of oil quickly lubricates engine components, reducing wear and preventing failures. I usually make it a habit to start the car a few minutes early to warm it up, which works even better when paired with the right oil. Don’t ignore the recommendations in your owner’s manual—changing the oil on time and checking its quality are crucial. Otherwise, long-term engine wear can lead to costly repairs. Now, I always keep 5W-30 on hand, and winters have become much smoother.
