Which provides better performance, 0W30 or 5W30?
1 Answers
Engine oil grades should be selected based on the vehicle model and condition. 5W40 oil is typically suitable for German cars, while 0W30 oil is suitable for domestic and American cars, as well as Japanese cars with over 150,000 miles. Therefore, these two oil grades are not directly comparable. Classification of engine oil quality from high to low: Full synthetic oil, semi-synthetic oil, and mineral oil. Full synthetic oil outperforms other oils in terms of power, noise reduction, cleanliness, and longevity. Many well-known brands offer full synthetic oils, with replacement intervals ranging from 7,000 to 10,000 kilometers. High-end imported oils like GT Magic Red, which are PAO full synthetic oils, offer even better overall performance, with replacement intervals reaching up to 15,000 kilometers. Semi-synthetic oils have significantly poorer overall performance, with replacement intervals typically around 5,000 kilometers. Mineral oil is the lowest quality oil, containing more impurities and less refined, resulting in poor overall performance. Selection of oil viscosity: Oil viscosity should first be chosen based on the vehicle model and condition. With the exception of certain models, in most cases, Japanese cars use 20-grade oil, American and domestic cars use 30-grade oil, and German cars use 40-grade oil.
