Does Engine Oil Affect Fuel Consumption?
1 Answers
Engine oil affects fuel consumption. It provides good lubrication for the engine, reducing friction, cleaning, buffering, and sealing. Poor lubrication from engine oil increases the engine's motion resistance, leading to higher fuel consumption. Therefore, engine oil not only impacts fuel consumption but also affects the engine's lifespan. It is recommended to change the engine oil every 5,000 kilometers. Over time, engine oil degrades, reducing viscosity and lubrication efficiency, increasing friction. Prolonged use of degraded oil can cause severe engine wear, enlarging the gaps between moving parts, resulting in abnormal engine noises that worsen with continued wear.
