Adblue is not something that you just stick in your normal diesel fuel tank and see some kind of magical improvement. You've got the wrong idea about what its all about.
The Adblue system is designed to cut the emissions from a diesed engined exhaust system down to basically nitrogen and water. The actual Adblue liquid is held in a seperate tank and it is injected into the exhaust systems catalytic converter, where the normal toxic gases that the engine produces are re-burnt and converted into the less harmful substances that this process creates (ie the nitrogen and the water). The whole idea is to reduce the emissions to help to 'save the planet' ultimately.
