How Often Should You Refill AdBlue?
2 Answers
When the AdBlue level drops below approximately 20%, it's time to promptly refill the AdBlue solution. Here's some relevant information about AdBlue solution: 1. AdBlue works in the Selective Catalytic Reduction (SCR) system of diesel vehicles to catalytically convert nitrogen oxides (NOx) in exhaust gases into harmless nitrogen (N2) and water (H₂O) for emission. 2. AdBlue consists of 32.5% high-purity urea and 67.5% deionized water. Under normal circumstances, AdBlue is harmless to humans (if it comes into contact with skin, simply rinse with plenty of soapy water or clean water, but be careful not to get it in eyes or swallow it). However, under high-temperature conditions, AdBlue may release ammonia gas (NH₃). NH₃ can have corrosive and irritating effects on human skin tissue upon contact. Prolonged exposure to ammonia gas may lead to symptoms such as skin pigmentation or skin ulcers.
I've been driving a diesel car for several years, and the frequency of adding AdBlue is generally around every 10,000 kilometers, but the key is to check whether the urea warning light on the dashboard is on. Daily driving habits have a big impact—for example, highway driving consumes less, while city traffic congestion consumes it faster. I keep a large container at home and check the fluid level when refueling, topping it up when it's low, which is simple and convenient. Don't ignore this—if you don't add AdBlue, the car might limit power, crawl like a snail, and you'll end up spending money on system repairs. It's best to use genuine AdBlue fluid, as off-brand products can easily clog the nozzles, especially in winter when temperatures are low. Make sure to tighten the cap after refilling to avoid crystallization. Developing a habit of regular maintenance will make the car more durable and reduce problems.
