For every 100 liters of diesel, 3~5 liters of AdBlue should be used. Here are the specific details about AdBlue: Dashboard display of AdBlue: The remaining amount of AdBlue is displayed on the dashboard, similar to the fuel gauge.

How much AdBlue should be added? I've driven diesel vehicles for over a decade and have experience. Generally, fill the AdBlue tank to full but avoid overflow, as excess can damage the system or cause waste. Different models have varying capacities—for example, my pickup's AdBlue tank is 25 liters, so I fill it to around 24 liters to leave some space; smaller vehicles like sedans may hold 10-15 liters, so fill up to the MAX indicator line. The dashboard usually has a warning light that signals when it's time to refill. Pour slowly when adding to prevent foaming, and use reputable brand AdBlue to avoid impurities affecting emission control. It's best to check before long trips, as low levels can reduce engine power or cause excessive emissions. Remember, regular maintenance extends the SCR system's lifespan—don’t wait for an alert to act. In short, fill according to the tank size, and be careful during operation.
