How much urea should be added at one time?

Urea should be added 5L at one time. Introduction to automotive urea: Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5% and the solvent being ultra-pure water. The raw materials are special automotive urea and ultra-pure water. Function of automotive urea: Automotive urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. It mainly plays a role in purifying exhaust gases in vehicles, reacting with nitrogen oxides in the exhaust to reduce nitrogen oxide emissions. The primary function of automotive urea is to convert nitrogen oxides (NOx) generated by diesel engines into non-toxic nitrogen gas (N2), reducing the NOx content in the exhaust to comply with national emission standards.
I've been driving diesel vehicles for several years, and every time I refill the urea, I wait until the dashboard alerts me about low fluid levels before handling it. Usually, I just top it up to the MAX line at the top of the tank. The exact amount isn't a fixed number—it depends on the size of your vehicle's urea tank. My old car had a smaller tank, so about 10 liters would fill it up, while my new one might take around 20 liters. The reason is simple: urea is used to reduce nitrogen oxides in the exhaust. Not adding enough or skipping it altogether can affect the vehicle's performance and pollute the environment. I typically check the fluid level every 5,000 kilometers to avoid getting stranded on the road. Overfilling can lead to spillage, which is wasteful and may corrode parts, so I carefully pour it using a funnel. Make sure to use the correct AdBlue solution and avoid mixing it with water or other liquids, as improper handling can trigger system errors and result in costly repairs. Just follow the manual's recommended refill amount—no need to obsess over the exact number of liters.
