How Often Should 0W20 Full Synthetic Engine Oil Be Changed?
2 Answers
0W20 full synthetic engine oil can be changed every 10,000 kilometers, but the actual interval should be determined based on the vehicle's condition. Below is relevant information about engine oil: 1. Definition: Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. 2. Precautions: Never use an adjustable wrench to remove the oil drain plug, as it can easily damage the threads. Loosening the oil filler cap before draining the oil helps the old oil flow out more smoothly. When tightening the oil drain plug, apply just enough force to secure it without over-tightening and damaging the threads. Some oil drain plugs come with copper washers to prevent leaks, which need to be replaced periodically, and the drain plug itself should also be replaced regularly.
I've always used 0W20 full synthetic engine oil. After driving for over a decade and changing oil numerous times, experience tells me not to blindly trust the so-called 10,000-kilometer oil change standard – adjustments should be made based on actual conditions. For instance, with frequent city traffic congestion or extensive summer AC usage in high temperatures, I recommend changing every 6,000 to 8,000 kilometers. Otherwise, the oil tends to oxidize and thicken, compromising lubrication. Last time when I reached 9,000 km, the engine noise noticeably increased, prompting an immediate visit to the repair shop. Develop the habit of checking dipstick color – change early if it turns black or cloudy. Don't jeopardize your engine to save small money. Also pay attention to oil condition maintenance during seasonal transitions to extend lifespan while saving costs.
