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

I just ordered Motorcraft DEF off of Amazon. My 2018 Ford F350 manual specifies I use Motorcraft brand. This is my first diesel, so like many other newbies I am apprehensive, most likely for no good reason. Is Motorcraft a good brand? Thoughts?
