Def fluid
Have a 2011 Duramax. Have had a sensor problem. Dealer says the def from Walmart is giving some problems. Any thoughts.

Its the universal answer from the dlr. I had a 2011 GMC and the tank had to be replaced at 600 mi and again at around 75k mi. As well as a sensor a couple of times. It has nothing to do with the def you are using.
