What Type of Engine Oil is Suitable for Cars in Winter?
2 Answers
Winter engine oil models typically have a multi-grade viscosity of 5W-30. Below is a partial introduction to winter engine oil models: 1. State: In winter, temperatures are low, and conventional engine oil may turn into a semi-solid, semi-fluid state, reducing its flowability. Poor-quality oil might even stop flowing entirely. 2. Viscosity: It is best to choose engine oil with low base oil viscosity, a low pour point, and strong anti-wear performance. Most car owners in China opt for multi-grade viscosity oils like 5W-30 or 10W-40. The number before the 'W' in the oil grade represents the oil's low-temperature flowability.
Choosing the right winter engine oil is indeed crucial. From my experience, the key is to look at the 'W' number at the beginning of the oil grade. For example, 0W means the oil can still flow at -35°C, while 5W can handle -30°C. Last year, I switched to 0W-40 full synthetic oil for my German car, and even at -20°C in the morning, there was no noticeable sluggishness—the engine started right up. For those in northern regions, it's especially important to avoid using high-viscosity summer oils, as cold starts with dry friction can seriously damage the engine. Here’s a handy tip: when parking outdoors, block the radiator grille with a cardboard sheet to help the oil warm up faster. Also, regularly check the oil level, as cold temperatures can cause fluctuations in oil volume.
