Can any other fluid be used in the DEF system?

No, it is not recommended to use any other fluid in the Diesel Exhaust Fluid (DEF) system besides DEF. Using any other fluid can cause damage to the system and affect the performance of the vehicle. DEF is specifically designed to work with the system and meet emission standards.

Can one pee into diesel exhaust fluid tank?

Stupid idea. These catalyst systems are extremely strict about how pure the DEF must be. If it detects impurities in the DEF, it'll first derate, and eventually shut down, the engine. Then, the DEF tank, DEF doser, and all DEF lines will have to be removed and thoroughly cleaned out (in the case of the lines and the tank, they'll probably just be replaced outright). The DEF doser will have to be cleaned out and possibly replaced, then all that has to be reinstalled.

What age does a tractor trailer have to be to enter California?

Tractor Trailers got to meet EPA requirements. Because California has so much pollution in the air. "DEF fluid" can get about 2,700 miles to a 25 gallon tank, that is what my 2011 Volvo is averaging. DEF Fluid helps your truck burn cleaner fuel, so you put out less pollution, so you can better reach California EPA requirements.
