Urea as a carbon cleaner?
 

Yes, i know... water injection, alt.fuels, blaablaa...

I was just sitting on the comp with a program on discovery rolling, and heard "burn off carbon"... so, being a rotard, i turned my head, rewind the program on Discovery, and checked it out...

What are your thoughts on applying this as a premix in an OEM rx once in a while? I just recorded it on my cellphone, uploaded it and asking here. Im not going to do it... i was just curious :)

and no, i did not search :P

I think you would be better off trying to find an E85 pump. Not too thrilled at the idea of pee pee in my car.

Urea solutions (DEF) are injected into the exhaust after it has left the engine. It's meant to keep the exhaust components clear of carbon, not the engine.
