Diesel Exhaust Fluid (DEF)
This is what's starting another urban legend.
Diesel Exhaust Fluid does include urea, which is processed animal urine.
I did forward the article to Mark who is in the article.I had to pick with him at lunch Sat. about the urine deal..He thought that was funny.Couldn't believe the paper would put that in there..lol
But that is in new conditions. Can you tell me what that looks like in 3-5 years when things have worn a bit?
