Can you use water instead of DEF?

If you remove the urea from the DEF -- that is, if you run water through the injectors instead -- it probably won't hurt anything, since you're reducing the level and quantity of corrosive reactants inside the stainless steel SCR system.

What can you substitute for DEF fluid?

DEF is urea or otherwise known as aqueous ammonia. Windshield washer fluid that contains ammonia will do in a pinch.

Can you run water in DEF tank?

Registered. If you put water in an EMPTY DEF tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate NOX (Oxides of Nitrogen) via the SCR (Selective Catalytic Reducer).

Can you use pee as DEF fluid?

The urea found in urine is not in the proper concentration needed for DEF, nor is it of a sufficient level of purity, in either urea or water. The bottom line, to spell it out just one more time… urine and DEF = Never. DON'T PEE IN YOUR DEF TANK!

What happens if I use water instead of AdBlue?

If you fill up with water instead of AdBlue, you can block the injector and damage the catalyst. Progressive damage to your SCR system can reduce engine performance and actually increase the fuel consumption per mile or kilometer. Your vehicle will not maintain the emissions allowed for a Euro 6 car.

How do you make DEF fluid?

From a strictly chemical disposition DEF is a mixture of 67.5% deionized water and 32.5% urea. Urea is a compound in Nitrogen that turns to ammonia when heated and is used in a variety of industries. Urea is technically derived from a byproduct of urine but for mass production purposes it is synthetically made.

Can you drive a diesel without DEF?

SCR Systems Modern trucks will not run without the DEF. Hence the need for diesel truck owners to check their fluid levels frequently. Reducing emissions should be everyone's goal. Maintaining your vehicle would also reduce emissions and DEF consumption.
