No, the 2011 Chevy Duramax diesel engines do not use DEF (Diesel Exhaust Fluid). DEF was introduced in the Duramax line starting with the 2013 model year to comply with stricter emissions regulations. The 2011 model does not have the selective catalytic reduction (SCR) system that requires DEF.
5 year 100k miles for the engine 3 year 36,000 for whole vehicle

It is illegal. The EPA requires all vehicles to have a 3-way catalytic converter that lowers toxic emmissions. The catalytic converter must also be made up of specific metals in order to qualify as legal in the U.S. Almost the entire world requires your car to have one.
Look under the vehicle and count them.
the cummins. Hands down. if you said any dodge older than a 2005, I'd go with the duramax, but the trannies in the 05 and up dodges are much better, and you cant beat a cummins for power and reliability.
