Is urine really enough in the diesel tank?

Adblue as an important diesel additive is currently a scarce commodity. High gas prices ensure that the production of the exhaust gas cleaning agent is becoming more and more expensive. Producing Adblue yourself from urine is not an alternative. Damaged components and high costs are the result, warn car manufacturers.

AdBlue is required as an additive by around ten million diesel vehicles in Germany. Bottlenecks are currently threatening due to rising energy prices. The nitrogen works Piesteritz as the largest manufacturer produce the indispensable exhaust gas cleaning agent not for several weeks. Some private diesel vehicle owners may also be wondering whether the aqueous urea solution could be produced themselves. The short answer: no.

Even car manufacturers themselves warn against other diesel additives, as these affect the catalytic converter or others damage important components of the vehicle could. In addition, the manufacturer’s guarantee can become invalid (source: Car picture).

Urine with water as an Adblue substitute is not suitable because residual substances can accumulate in the tank and in the lines. The reaction with oxygen and other substances should ensure that the mixture begins to rot over time. Just one expensive repair can help then.

With industrially manufactured Adblue, the urea cleaned from other organic compounds. Numerous other substances, such as proteins, would otherwise cause problems for the catalyst.
