How Often Should Castrol Full Synthetic Engine Oil Be Changed?
2 Answers
Castrol full synthetic engine oil should be changed every 10,000 kilometers or once a year. Advantages of full synthetic oil: Compared to mineral oil and semi-synthetic oil, full synthetic oil has the following advantages: stable physicochemical properties, better lubricity, high-temperature oxidation resistance, and a longer oil change interval. It also has good low-temperature fluidity, making it easier to start the car in cold weather, and provides excellent engine cooling performance at high temperatures. Precautions for adding engine oil: When adding engine oil, avoid adding too much or too little. If there is too much oil, it will increase the resistance of moving parts. Excessive oil can also easily enter the combustion chamber and participate in combustion, leading to slow and incomplete combustion, resulting in unstable engine idle and easy stalling, as well as sluggish acceleration response.
I've been driving for twenty years, and full synthetic oil is indeed durable. For big brands like Castrol, it's perfectly fine for regular family cars to go 8,000 to 12,000 kilometers before an oil change. But don't just focus on the mileage—consider your driving conditions too. For someone like me who often drives on highways, changing at 12,000 kilometers is no issue. However, if you're frequently stuck in city traffic with short trips where the engine never reaches optimal temperature, you might need to change it at 8,000 kilometers. You can check the oil dipstick yourself—if the oil is black with a burnt smell or the viscosity has noticeably degraded, don't hesitate to change it immediately. By the way, German cars or those with turbochargers usually require earlier oil changes, especially older vehicles that need more frequent checks.
