The effects of not adding urea to trucks: 1. Environmental pollution. The reason for adding urea to vehicles is to convert harmful substances in the exhaust into harmless nitrogen and water vapor. 2. Vehicle damage. If there is no urea circulation for a long time, components such as the nozzle, pipelines, and urea pump are prone to crystallization blockage or high-temperature damage. 3. Insufficient vehicle power. Precautions for using vehicle urea: 1. During the use of vehicle urea, it is important to ensure the urea solution is filled to 100% (90% can be filled when temperatures are low in winter). When the urea solution is depleted to 20%, it needs to be refilled. 2. Regularly check the urea level and inspect for any urea solution leaks. Do not overfill or underfill (not less than 18%). 3. When refilling urea, remember to wipe the dust around the filling port with a cloth to prevent dust from entering the urea tank.

I've been driving a truck for long-distance hauls for nearly a decade, and skipping the urea is really not a smart move. Urea is used to reduce emissions, and not using it is basically letting the engine spew out more harmful nitrogen oxides, polluting the air. Over time, it not only harms the environment but also affects the health of people around, like worsening asthma. Plus, the truck itself will start acting up: the system detects the lack of urea and may limit power, force lower gears, making it hard to pick up speed on the highway. The key point is, there are government emission regulations—trucks without urea might fail annual inspections or even get fined. In the long run, repairs become a bigger hassle, with higher costs for replacement parts. Bottom line: don’t cut corners for short-term convenience, or you’ll end up hurting yourself and others.

From a cost-saving perspective, skipping urea is actually a trap. A friend of mine tried it, thinking he could save some money, but it backfired: the urea system automatically triggered an alarm, the engine power reduced, causing fuel consumption to skyrocket, burning several extra liters of diesel per 100 kilometers. Over a few months, this added up to hundreds of extra dollars. Worse yet, system components are prone to damage, such as clogged nozzles or failed catalysts, with repairs starting at thousands of dollars. There's also the risk of fines—environmental inspections for excessive emissions can result in penalties of thousands. So, honestly, adding urea is the smarter choice, preserving your vehicle's performance and avoiding trouble.

Skipping urea addition significantly impacts truck engine performance. I experienced this firsthand: failing to refill on time triggered immediate power limitation, sluggish acceleration, and struggling uphill climbs. This occurs because the SCR system relies on urea to break down exhaust gases – without it, the protection mechanism kicks in to reduce power output. Prolonged neglect leads to internal component issues like carbon buildup and catalyst aging, increasing maintenance frequency. Additionally, fuel consumption rises, wasting money on extra diesel. Safety risks emerge too, such as losing control on slopes due to insufficient power. Regular urea tank checks are essential for smooth operation.
