Can High-Quality Engine Oil Save Fuel?
2 Answers
High-quality engine oil can save fuel. Good engine oil has better low-temperature fluidity. Below are some introductions about high-quality engine oil: Advantages: High-quality engine oil has better low-temperature fluidity. High-quality engine oil requires shorter warm-up time. High-quality engine oil has lower consumption. During engine operation, some oil consumption is inevitable. Although oil consumption mainly depends on the engine's technology and design, different oils have varying consumption rates. Generally, under the same vehicle or operating conditions, full synthetic oil has lower volatility compared to mineral oil. High-quality engine oil is less prone to aging. Composition: It uses better components from crude oil, undergoes chemical reactions, and is artificially synthesized, resulting in superior quality, better thermal stability, oxidation resistance, and viscosity change resistance compared to mineral oil.
Actually, good engine oil can indeed save fuel to some extent. I've worked in repair shops for many years and often get asked this question by car owners. The key factors are the oil's viscosity and lubricating properties. Premium full synthetic oils have better fluidity, which reduces friction resistance between internal engine components. When the engine runs smoother, it naturally consumes less fuel. However, don't expect a dramatic fuel consumption drop immediately after changing oil - the fuel saving effect is typically around 3% to 5%. I've seen many people use incorrectly high viscosity oil, which actually increases fuel consumption. The vehicle's condition also matters - older cars perform better with high-mileage specific oil. Remember to change oil regularly every 5,000 to 10,000 kilometers, otherwise even the best oil will lose its effectiveness.
