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

I own a small trucking company, two cattle ranches and I pull our Montana 5thWheel with a diesel RAM truck. On average I pay for over 150 gallons of DEF per week. I learned that I save over $2.00 per 2-1/2 gallon jug by my employees buying at WalMart rather than at truck stops and other sources. We have had no problem with WalMart DEF in the Blue jugs plus it is cheaper than even bulk supply.
