Is 0W40 Oil a Multi-Season Oil?
2 Answers
0W40 oil is a multi-season oil, where 0W indicates the oil's cold-start performance. The smaller the number, the better the oil's cold resistance. The oil serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, absorb shocks, and resist wear. The steps for changing the oil are: 1. Lift the car, remove the underbody panel, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug and use an air gun to blow into the oil filler port for two minutes; 3. After draining, tighten the oil drain plug and wipe it with a tissue to check for leaks; 4. Reinstall the underbody panel, lower the car, and use a funnel to add oil through the filler port.
Speaking of 0W-40 engine oil, I've driven for ten years and tested it in the freezing winters of the north and the scorching summers of the south—it's definitely an excellent all-season choice. The first number, 0, indicates strong low-temperature fluidity, allowing quick engine starts even in sub-zero winter conditions and reducing wear. The 40 represents high viscosity at high temperatures, providing solid protection when the engine runs in summer heat. I find it incredibly convenient—no need to switch between winter-grade and summer-grade oils like with older formulations. Year-round, it's hassle-free. During routine maintenance, I've noticed stable engine temperatures, reduced noise, and consistent fuel consumption. Always choose reputable brands when changing oil; don't cheap out on knockoffs to avoid engine aging issues. Even in extreme weather, like freezing points or 40°C heat, 0W-40 holds up, ensuring safe and worry-free driving. In short, as an all-season oil, its design tackles annual temperature fluctuations effortlessly.
