Can automobile urea still be used after three years?

Urea in automobile mainly plays the role of purifying exhaust gas, and reduces the emission of nitrogen oxides by reacting with nitrogen oxides in automobile exhaust gas. So, can urea for automobiles still be used after three years?

1. Try not to use urea for vehicles after three years because the shelf life of urea for vehicles is very short. If unqualified vehicle urea is used, the quality of vehicle urea may decrease, and the purification effect cannot be achieved. In severe cases, the urea pump will be damaged.

2. Vehicle urea is a pure substance, which is composed of 32.5% high-purity pumped urea and 67.5% ultra-pure water. If the temperature is lower than 10℃, it can be stored for 36 months. When the temperature is less than 25℃, the storage time is generally about 65438 08 months. If the temperature is less than or equal to 30℃, the storage time is only one year.

3. There are different brands of urea for vehicles in the market. When choosing, try to choose the one with guaranteed quality. Using inferior urea in vehicles will damage the engine system. In addition, when purchasing urea for vehicles, the delivery time is generally within six months. If it has been more than one year, try not to use it again.
