How Often Should Synthetic Oil Be Changed?
3 Answers
Fully synthetic oil can typically be changed every 10,000-12,000 kilometers or every six months. If the driving environment is dusty, the temperature is relatively low, or the vehicle is frequently used for short trips, it is recommended to shorten the replacement interval of fully synthetic oil to ensure smooth engine operation. Here is some extended information about fully synthetic oil: 1. Introduction: Fully synthetic oil is called "fully synthetic" because it no longer uses crude oil-refined base oil. 2. Advantages: Compared to traditional oils refined from crude oil, fully synthetic oil is purer, which results in more stable performance.
I've always believed that the interval for changing synthetic oil depends on your car's condition. Having driven an SUV for nearly a decade, I'm accustomed to changing it every 7,500 miles or 8 to 10 months, especially since city traffic congestion puts more load on the engine. Delaying the change can cause the oil to thicken, affecting lubrication. During summer road trips in high temperatures, I check the dipstick in advance—if the oil turns black, I change it immediately. Although full synthetic oil is more expensive, its better heat resistance allows it to last up to 8,000 miles. Don’t forget to replace the oil filter during the change—it’s crucial for filtering out impurities.
From my perspective, the most reliable method to determine synthetic oil change intervals is to check the owner's manual. Manufacturers typically recommend changes between 5,000 to 10,000 miles or every 12 months. I drive a hybrid vehicle, and my manual specifies oil changes every 7,500 miles, which I follow strictly. For gentle driving habits, such as more highway miles with less stop-and-go traffic, you can reasonably extend this to 10,000 miles. However, don't be complacent—aged oil can lead to increased engine fuel consumption and diminished performance.
