Clutch fluid is generally changed every 2 years or approximately 40,000 kilometers. Below is more relevant information: 1. Mastering the use of the clutch: Avoid unnecessary pressing of the clutch pedal. During normal driving, the clutch in a car is in a tightly engaged state and should not slip. Except for starting the car, shifting gears, and low-speed braking, avoid pressing the clutch pedal unnecessarily or keeping your foot on it. 2. Hazards of prolonged clutch engagement: Keeping your foot on the clutch pedal for extended periods while driving can easily lead to clutch slippage, clutch disc burning, and other issues. In severe cases, it may even cause the clutch pressure plate and flywheel surface to burn or wear out, leading to failures such as the clutch pressure spring losing its temper. Additionally, it can result in increased fuel consumption and vehicle wear, raising driving costs.

I've been driving for fifteen years, and the clutch fluid replacement interval is quite important. Generally speaking, it should be changed every two years or every 30,000 kilometers. I once neglected it for three years, and the clutch pedal became stiff, especially during cold starts in winter. Gear shifting was rough, and I almost had a minor incident on the highway. After replacing the fluid at the repair shop, it immediately became smooth again. Clutch fluid gradually absorbs moisture from the air, causing the fluid to become dirty and corrode internal seals. Prolonged neglect not only reduces clutch performance but may also lead to oil leaks or even system failure. In daily car maintenance, this small item should not be overlooked. Regular replacement and maintenance will make your vehicle more durable.

Based on my experience, it's quite reliable to recommend replacing the clutch fluid every 2 to 3 years. Just like brake fluid, it's a crucial component in the hydraulic system that can absorb moisture and oxidize over time, leading to a decrease in boiling point, which directly affects the responsiveness and sensitivity of clutch operation. I've checked my own car's user manual, and many mainstream brands like Honda suggest a two-year interval, while others like BMW might recommend three years. If you frequently drive in humid conditions or often take long trips, the interval should be even shorter. Regularly check the fluid level and color changes in the reservoir; if it appears dark or cloudy, address it promptly to prevent minor issues from becoming major problems. Regular maintenance of this fluid can significantly extend the lifespan of vehicle components.

Last month, my friend's clutch fluid was overdue for replacement by two years, making gear shifts as stiff as stepping on a rock, and the car struggled even on small slopes, nearly causing an accident. Now I've learned my lesson and change it every two years on the dot—it doesn't cost much but prevents sudden breakdowns. Online research recommends a two-year cycle, especially in rainy cities where it's even more crucial to stay on top of it. Regularly checking the fluid reservoir for bubbles or impurities and addressing them promptly keeps things worry-free.

From a driving safety perspective, clutch fluid must never be left unchanged for too long. If the fluid deteriorates and fails, it may cause delayed clutch response in critical moments, significantly increasing the risk of control loss. I insist on changing it every two years, such as during routine maintenance, which saves both money and hassle. It's also crucial to regularly inspect the fluid quality—clear and transparent is a good sign, but if it appears dark or contains bubbles, it should be replaced immediately. Ensuring the safety of yourself and others makes this small investment absolutely worthwhile.
