Diesel exhaust fluid. Opinions!

Currently have a '04 gmc 2500 cc duramax. It's been a great truck. In 2010 we purchased a Sierra 355qbq. Even though it did a decent job of pulling the big 5er, I was considering buying a new bigger truck.

That was until I heard about def.. I did my research, and couldn't come up with definitive answers. But, 3 diesel mechanics I talked to said, stay away from it. Using terms like, "unproven, corrosive, a born lemon, and so on. So I passed on buying new and made some updates to my current ride.

My questions are, who has real world experience with def?, and what are your opinions? Does anyone think it will be repealed in the future? Thanks.

Ford has an EGR and DPF system in there 6.7 power stroke
The whole thing is revolving around what's coming out of the tail pipe
At this point it's like Beta vs. VHS either one could come out on top.

I would say it is here to stay until they come up with something "better". I hate what they have done to the new diesels. The emmisions garbage is killing them. I have a 2008 Dodge 6.7 Cummins and it was terrible on mileage. I deleted all the power robbing, motor killing, mileage killing emmisions equipment and picked up 5 mpg. Engine oil stays cleaner and engine temperature has dropped. Really like the truck now.

Here you go type EGR delete in the search box and you will probably be reading for a while. Great forum to join if your a Ram owner.

EGR valve, DPF and NOX filters. I also opened up the air horn and modified the stock air box for better flow. To do this you need to use a programer to fool the computer to believing everything is intact. I am running a Smarty JR programer. It took me about 6 hours to do the whole works and about $750. It has been trouble free and worth every penny. It is a totally different truck now and it runs way better and never goes into regen. I picked up 5 mpg.

DEF is not new, look at European engines. lots of guy pulling have it ford and GM. Other than pump issues and figuring out consumption, it seems to do a great job.

We bought a "new to us" 2006 Dodge Ram 2500 Cummins. When I first started reading these forums regarding diesel TV and heard the term DEF, I thought it was some kind of joke, you know, like a left handed screwdriver or a knipple valve. Since we'd never owned a diesel before, the term was totally new to me. Guess I'm glad we bought an '06 before Dodge started screwing with the exhaust and emissions.

For me it's not the additional cost of the fluid, or that I don't care about the environment. It comes down to, will the system give me nothing but problems over the years. Especially living in a cold climate.

It bothered me that the manufacturers will not warranty it past the 3 year/36k mile. Aren't emissions equipment supposed to have a 100k warranty? Read in a article that the Ford exhaust system weighs over 800 pounds. Also, hard to modify these trucks, illegal in most cases.

However, after driving both the new Ford and Chevy models, I was impressed. Quiet, internal engine braking, built in brake controllers, stronger frames, navigation, and so on.

Maybe after a few years if def proves itself, I'll change my mind. Time will tell.

The dot in all states has RAISED the Max gvw on new over the
Road trucks because of the increased weight added for emissions.
That is bs imo.
