I have been driving a '13 without DEF since Aug.'13. No issues. The previous '08 DPF eqiped no DEF one I drove for 2 years had no issues either.

2013 model Ram Cummins has DEF. You must be running a 2012.

I did not say it was a Ram. They are IC Navistar school buses. The comment was about diesels trucks not specifically a Ram,Chevy,or Ford. The new '14 school buses that the school crop. bought are def equiped.

I'm sorry, I had the OP's question in my head when I posted.

I was one of those that was "against" DEF on a diesel. While I still don't like the complexity it adds, I do agree is does add mpg via fewer regens.

I think alot of you get this confused but DEF has nothing to do with the DPF. The DPF is a soot filter/trap and DEF is injected in exhaust to lower emmissions.

I am not sure what your objective is, but we recently switched from a 2012 Ram3500 4x4 crew cab dually (no def) to a 2014 same model (no def). So far we have seen better fuel mileage about 1 - 2 MPG better that we were getting on the 2012.

If you have 2014 Dually without Def, perhaps they are exempt, anyone know?

As the poster said on editing his post, his 2014 DOES use the DEF fluid.

It is really a non-issue with these new trucks. Used it problem free on my 2011 Ford and now on my new Ram.

Takes all of five minutes to add every once in a while, all dependent on how you were using the vehicle (towing/loaded versus empty) for duration between re-fills.

Edited to show 2014 does have DEF, sorry

Is DEF required by the EPA? I thought DEF was a choice over Dodge's earlier DPF BluTec system. Dodge had a lot of problems with their DPF on the 6.7L so I was under the impression they changed to DEF as a result. I have a 2007 Dodge with DPF and had TONS of issues although they appear to have been resolved.

DEF is not required, but it does not appear that there is a current engine that can meet EPA without using this technology. I'm all for simplifying the emission system if someone can figure out how to make a cleaner burn.

Thanks, I was wrong!

The DEF started in 11 Chassis Cabs.

My fill is right behind the cab and the tank sits under rear half of the crew cab.
