AdBlue is a urea-based fluid that is specifically formulated for use in diesel engines with selective catalytic reduction (SCR) technology to reduce emissions of nitrogen oxides (NOx) in the exhaust gas. It is made from a high-purity urea solution and requires a specific manufacturing process to meet the required standards.
It is not recommended to make your own AdBlue. AdBlue is a very high-purity urea solution and can be corrosive to some materials and surfaces. It also requires a specific manufacturing process to meet the required standards and ensure the quality of the product, which is difficult to replicate at home.
Also, using a homemade solution can cause damage to the SCR system and the engine, and may void the vehicle’s warranty and lead to the vehicle failing emissions testing. Additionally, making your own AdBlue may not be legal in your area, therefore, it is important to check the regulations of your country or state.
It’s important to always use the correct fluid and to follow the manufacturer’s recommendations for refilling and maintenance of the AdBlue system. It’s also recommended to purchase AdBlue from reputable suppliers to ensure the quality of the product.
