Walmart has it in store!
All of our tractors require def fluid so when I realized Walmart sold the brand I was go to Home Depot to get I pick it up when I do my household shopping. One less stop and they always have it on the shelves.

the blue Def works great Walmart carries it and it is about the cheapest place if I have to buy it in any other store it is double the price and if I cannot find the blue DEF I am forced to use no name brands and I have nothing but problems check engine light comes on I will get a 75 mi to 15 mile an hour see dealer immediately as soon as I put the blue d e f back in all my problems go away.

Good product at a great price
Good product at a great price. The pour spout consistently works well and it's stored in a cool area instead of on a sidewalk out in the sun or in the garden department.
