How Often Should You Add Urea to Your Car?

Car urea should be added approximately every 2000 kilometers. Details about car urea are as follows: Urea consumption: 3 to 5 liters of urea are used per 100 liters of diesel, equivalent to 3% to 5% of fuel consumption. Function of car urea: Car urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. Reason for adding car urea: The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulates. While particulate emissions can be reduced through technical means within the engine, the exhaust primarily contains nitrogen oxides. By injecting urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures, which then reacts with nitrogen oxides in the presence of a catalyst to produce harmless nitrogen and water.

I've driven diesel vehicles for ten years and have some insights into DEF (Diesel Exhaust Fluid) refill frequency. It's not a fixed rule – it largely depends on your driving habits and distance. Generally, you'll use 3 to 5 liters of DEF per 100 liters of diesel consumed. For example, since I frequently drive long distances, I need to top up DEF every 3,000 km on highways. But my colleague who only uses the car for short urban commutes may only refill every three to four months. There's a dedicated warning light on the dashboard – when it turns yellow, it's time to act, otherwise your vehicle's performance will be limited, significantly impacting safety. I recommend quickly checking the DEF level before each fuel refill, or topping up before long trips. In winter, remember to prevent freezing because low temperatures can cause DEF to crystallize, affecting its performance. Consumption varies by vehicle model, so always consult your manual – developing good habits is the most hassle-free approach.

I drive a diesel SUV daily and pay great attention to its environmental performance. Urea is used in the SCR system to help reduce exhaust pollution, and the frequency of addition depends on the specific situation. On average, it needs to be added every 5,000 kilometers or so, but if you frequently drive on highways or carry heavy loads, the interval is shorter. Don't ignore the dashboard warning light to avoid the system forcing a speed limit, which could affect driving safety. I check the fluid level every time I refuel with diesel, which is quick and easy. Remember to use standard AdBlue products, as using the wrong one may damage the nozzle. It's recommended for new car owners to start with the basics and consult the 4S shop for peace of mind. Developing regular maintenance habits can extend engine life and avoid penalties for environmental issues.

I've been driving my diesel sedan for several years and am quite familiar with adding urea. Most of the time, when the dashboard light comes on, it's time to refill – this signal shouldn't be ignored. The consumption during driving is about 0.03 liters per kilometer, so you might need a refill after around 3,000 kilometers. For urban short-distance drivers, topping up every six months is sufficient, while long-distance travelers need to do it more frequently. I personally check the fluid level weekly to avoid getting stranded midway. Low system fluid levels can affect performance, and reduced power is troublesome. I recommend keeping a small spare can in the trunk for on-the-go refills. Developing good habits makes for a worry-free and safe experience.

As a diesel vehicle owner, I was initially curious about what urea is, but now I understand it's essential for the SCR system to treat exhaust pollution. How often should you refill it? It mainly depends on diesel consumption: 3-5 liters of urea per 100 liters of diesel. If you drive mostly in the city, you might refill a canister every quarter; if you drive more on highways, it could be monthly. Don't delay when the low-level warning light comes on, or the vehicle will enter a protective mode with speed limits, which is dangerous on highways. I recommend that beginners check the level monthly and top it up when it's below 1/4. Manually checking the tank location is straightforward and won't cause any issues. Proper maintenance not only saves money but also reduces emission problems, making driving more worry-free.
