You cannot change the engine oil without replacing the filter. The reason is: The performance of the oil filter directly affects the lubrication effect of the oil on the engine. The steps for changing the engine oil are: 1. Use a jack to lift the vehicle, locate the drain plug, and loosen it to drain the oil; 2. After unscrewing the oil filter, place a container underneath; 3. Replace with a new oil filter and add new oil. The precautions for changing the engine oil are: 1. Choose the right oil for your vehicle; 2. Change the oil as much as possible when the engine is warm to ensure all the old oil is drained; 3. The oil filter must be replaced when changing the oil; 4. The amount of oil added should be appropriate, as indicated by the dipstick; 5. After adding the oil, start the engine and check for any leaks in the components.
It's really not recommended to change the oil without replacing the filter. After decades of driving, I've seen too many lessons learned. The filter traps various metal shavings and impurities. If not replaced, the new oil gets contaminated quickly, accelerating wear on internal engine components and shortening their lifespan. Over time, clogged oil passages may cause abnormal noises and power loss. In severe cases, it could lead to major engine repairs costing thousands – definitely not worth it. I always replace the filter when changing oil; it's inexpensive, around 100 yuan, and ensures engine health for worry-free long-distance driving. Regular maintenance isn't just about saving money – it's mainly to avoid unexpected breakdowns that could disrupt your trip. Filter replacement is actually simple; just consult your manual, and follow the standard workshop interval of every 5,000 kilometers.
