Can Using High-Quality Engine Oil Save Fuel?
2 Answers
Using higher-quality engine oil can relatively save fuel. Here is the relevant content introduction: 1. Function: High-quality engine oil can better protect the engine, offering superior lubrication performance, better low-temperature fluidity, and higher resistance to high temperatures. 2. Regular Engine Oil: Regular engine oil generally refers to mineral oil, while high-quality engine oil typically refers to full synthetic oil. Mineral oil is made from the inferior components of crude oil, and because impurities cannot be completely removed during the refining process, the base oil's strength is relatively weak and its performance is unstable. The typical oil change interval for mineral oil is 5,000 kilometers. Full synthetic oil, on the other hand, is a high-grade oil product made from the better components of crude oil.
Yes, I've personally used different engine oils and found that high-quality full synthetic oils can indeed bring slight fuel savings. The primary function of engine oil is to reduce engine friction, allowing components to operate more smoothly; premium oils like advanced synthetics have higher lubrication efficiency and lower engine resistance, which can marginally reduce fuel consumption. However, the difference isn't substantial—at most 1-2% savings—and depends on the vehicle model and driving habits. It's crucial to choose the correct oil viscosity, as using oil that's too thick (like in my older car) can increase engine load and raise fuel consumption. Other factors are equally important: underinflated tires or aggressive acceleration can negate the benefits, so comprehensive maintenance is key for better fuel efficiency. Regular oil changes are fundamental—they keep the engine clean and prevent carbon buildup from affecting performance.
