204 views
Engine oil improves mileage by reducing friction between engine parts, which allows the engine to run more efficiently. High-quality oils retain viscosity and lubricate better under different conditions, leading to improved fuel economy. Regular oil changes with the right type of oil also enhance engine performance, prolong vehicle life, and thus contribute to better mileage.
