What is the difference between 0w and 5w?
2 Answers
The difference between 0W and 5W is: 0W engine oil can normally start the engine at a minimum temperature of minus 35 degrees Celsius, while 5W engine oil can normally start the engine at a minimum temperature of minus 30 degrees Celsius. Here is some related knowledge about engine oil: 1. The meaning of W: W refers to all-season engine oil, and the number in front indicates the low-temperature fluidity of the oil, identified by the lowest applicable ambient temperature. 2. Applicability: For most regions in China, 5W is sufficient, and only some extremely cold areas should consider using 0W engine oil.
I'm just a car enthusiast who loves tinkering with my vehicle. Every year when winter approaches, I change the engine oil, and there's a big difference between 0W and 5W. 0W flows exceptionally well in cold weather—imagine turning the key at sub-zero temperatures and the car starts immediately, unlike 5W, which can get sluggish and leave you waiting. 0W provides better low-temperature protection, reducing engine wear, making it ideal for northern or extremely cold regions, though it's a bit pricier. I've used 5W in moderate climates, and it runs smoothly, handling summer hill climbs effortlessly. Choosing the right oil depends on climate and car model—some manuals recommend 5W for daily convenience, while switching to 0W might affect fuel efficiency. Ultimately, regular oil changes are key—don't underestimate these viscosity ratings, as they impact engine longevity and fuel economy. My advice? Stick to the manual and don't make random changes.
