I know.Our clean air Macks with the DEF ARE CONSTANTLY GOING INTO" RE GEN" NOW! Loss of power,gota pull over 15/20 minutes & let it run its course. Real POS !!! Sometimes we gota call our tow company have em towed back to the terminal.
DEF Fluid is Cow Urine sanitized purified mixed with Deionized water.One of our delivery guys told me the same thing about their Diesels.
He said that the government or who ever mandated the use of DEF has now found out that it is worst for the enviroment than engines that
don,t use it at all. Imagine that!
I have not done any research on that claim, so this is just hearsay for now...
My Duramax does not use the DEF, but it does go into a re-gen about once every tank of fuel.
Yes from what I read Google.WTF? I have not heard about this, stealth move by the EU.
Is it the direct injection engines that are affected?
